THE PERFECTED DURYEA CARRIAGE. Motor carriages are now occupying great attention both in Europe and America, and we may look for ex-cellent results as the consequence of this interest. In-ventors, in this country at least, have been heavily handicapped by lack of funds to carry out the expen-sive experiments which are requisite to the perfecting of the carriage. In England there appears to be now no lack of capital, but a sad lack of practical carriages. We have already illustrated the principal carriages of domestic origin and we now present an engraving of the Duryea motor wagon, which made an exceedingly creditable run in the recent inaugural trip from London to Brighton on November 14. The Duryea carriage won the first prize in the Times-Herald race in 1895 and also the prize in the Cosmopolitan race on Decoration Day, 1896. The run to Brighton was not a race, but a " go-as-you-please " run, still the time was taken, and once started the vehicles tried to pass one another, so that it was virtually a race in spite of all efforts to make it a procession. Out of fifty entries only some thirty carriages materialized, and many of them were left by the wayside between London and Brighton, to the great delight of wrli;ers for some of the dailies and weeklies, who now had a new object of ridicule. That some of the carriages greatly exceeded the legal limit of twelve miles an hour is shown by the time in which a Bollee car covered the entire distance, which was two hours thirty minutes. The Duryea carriages were late entries and were placed at the rear of the procession. While in the city it was not possible to turn out and pass the vehicles, but once in the open country the American carriages began to pull past carriage after carriage until they reached Reigate (22 miles) 30 minutes ahead of the next similar vehicle. Here lunch was served, and some of the carriages kept right on without waiting, which ac-counts for the remarkable time shown in some of the published reports ; this has been the cause of much mis-understanding. When the procession reformed, the Duryea carriage again forged ahead and reached Brighton forty minutes in advance, making a total gain of seventy minutes in about four hours. The roads were very heavy on account of the rain. It is said that the Duryea wagons were the only ones which were turned over to stable boys to be cleaned off with a hose ; the other carriages, having exposed parts, had to be wiped off like a locomotive.

Wheel and Pinion Cutting Engine Sloan and Chace   The engraving represents the No. 5 wheel and pinion cutting engine built by Sloan, Chace & Co., Newark, N. J. This machine is pro-vided with a revolving head with three spin-dles for carrying the cutters. These spindles are in quills, and are hardened and ground. The quills are in eccentric sleeves, to provide an independent adjustment for depth for each spindle. These eccentric sleeves have fast in their front ends binding nuts, threaded to the front ends of the quills, which gives an in-dependent end adjustment for each spindle. The head is revolved by means of a cam ring, moved by the handle shown at the left. The backward movement of this cam ring raises the latch out of the notch, and a pawl at-tached to the ring engages a pin fast to the head. The forward movement of the ring brings the head to the next notch. To feed the cutters to the work, the head is moved by means of the lever shown at the side, which is connected to a stud, provided with a pinion engaged with a rack, which is fast to the main slide. The spindle carrying the index plate and holding the work is hard-ened and ground, and is fitted to hold the same-sized spring chuck as the machinist's bench lathe illustrated in our issue of Jan. 2.

Employers and Workmen. 
In earlier days, when the world was less enlightened, employers and workmen held the relations of masters and servants ; now they are coadjutors. They form a sort of republic ; the employers hold the control in virtue of their position ; but they derive their prerogatives from the consent of the governed, and are bound to exercise their functions with all the moderation and for-bearance consistent with the maintenance of discipline. Similarly, it is incumbent on the workman to avoid everything that savors of offensive dictation, and especially not to pre-scribe terms that will have the effect of forcing American manufacturers to the alter-native of relinquishing their business or prosecuting it at a loss. They cannot expect to earn wages unless those who employ them make profits. .tip The resort to a strike is a! method of redressing grievances. muci, niary sacrifice to ttio

Cultivation and Preparation of Sisal Hemp in Yucatan. 
In our issue of Dec. 5, 1885, we described a machine for preparing " sisal" and other fiber, constructed under the supervision of Frank Darkin. Mr. Darkin has just returned from Yucatan, where he has been to start one of these machines in operation. From him we learn that almost the entire industry there is the cultivation and preparation of sisal hemp. Every farm, or hacienda, is the center of a plant. The soil, to make a bull of it, is a rock. The sisal plants are set out by native Indians, who are described by Mr. Darkin as a splendid set of men. The plants are set out in regular rows ; if there is a cleft in the rock the plant is set there, if not, soil is piled on the rock. The plants mature in five years, then the outer row of leaves is cut, and so on, for about fourteen years, when the plant blossoms, after which new plants are set out. A steam engine is required on each farm, and pumps driven by the engine are used for irrigation. The practice has been, hereto-fore, to use a wheel called a raspadora for preparing the fiber ; seven or eight of these wheels are used on a farm, each wheel re-quiring the services of two Indians, and turn-ing out from 7,000 to 8,000 leaves per day. One thousand leaves will produce about 50 lbs. of sisal. The machinery is of rude con-struction, and the wheels are dangerous to the operators.

Now this is very discouraging to the seeker for information, and yet it is not wondered at when we take into consideration the amount of labor and study which has been devoted to the subject, by those engaged in the business, and it is not too much to say that even the best informed on the subject are very far from perfection, inasmuch as they are con-. stantly called upon to change their mixtures on account of the variations in the different shipments of iron. To attempt to give a formula for universal adoption by saying, " So much of No. 2 to so much of No. 5, and

so on," is sheer nonsense, for the simple reason that when you receive a consignment of iron from the furnace which was ordered to be No. 4, you will find that no less than three or four grades of iron have been ship-peed to you, making it utterly impossible to follow any prescription, based on the number of the iron alone. The trouble can be over-- come after this manner : After first settling in your own mind what particular grade shall be called No. 1 and No. 6, with their intermediate numbers according to grade, you may then make from your own experience mixtures that will be intelligible to yourself, but would be useless to any one unacquainted with your methods of number-ing. But this is not all that enters into the successful making of rolls, or anything else that requires special mixtures If it were at all times profitable and convenient to use new iron, the business might soon be learned not cost nearly twice as much as coal in and by adopting the method suggested above. near coal-producing districts.

The cutter slide, and all other working slides, have been en-larged in length and wearing surface.

Mixture for Rolls. 
BY S. BOLLAND. 
The question is often asked by foundry-men " What is the best mixture for rolls ?" and again, " Why cannot we have a regular' set of mixtures, gotten up by some one who has had large experience in this class of work ?" Go where you will, you are met by these enquiries, and (strange as it may seem) no answer comes, at least none that is intel-ligible to the average moulder. Some have tried to give what purported to be the right mixture, made up of so much of " this," to so much of " that," supplementing the formula by saying that good rolls were made at such a place by the mixtures given. Again, you go into shops where they make a specialty of rolls, and ask for their mixtures, and naturally, they shake their heads, and express by the look they give, as well as they could by a multitude of words, " Not much." Now this is very discouraging to the seeker for information, and yet it is not wondered at when we take into consideration the amount of labor and study which has been devoted to the subject, by those engaged in the business, and it is not too much to say that even the best informed on the subject are very far from perfection, inasmuch as they are con-stantly called upon to change their mixtures on account of the variations in the different shipments of iron. To attempt to give a formula for universal adoption by saying, " So much of No. 2 to so much of No. 5, and

THE AMERICAN MUSEUM OF NATURAL HISTORY—ITS COLLECTIONS AND WORK—THE MOUNTING OF THE ELEPHANT " TIP." The assertion that those who live in a city often know least about its institutions has become a truism. It is safe to say that comparatively few New Yorkers have an adequate idea of the American Museum of Natural His-tory, which is one of New York's most notable institu-tions. It was founded over 20 years ago, the original law under which its charter was acquired being passed in 1871. To the original building addition after ad-dition has been added, a new lecture hall has been built, and to-day the richness and extent of the collec-tion is such that in the nearly  150,000 square feet of floor space. the majority of which is now at the com-mand of the in-stitution, bar e 1 y adequate room is found for the dis-play of the riches of the collections. Mineralogy, geol• ogy, paleontology, botany, natural history, in all its divisions, and an-thropology, a r e the heads under which the many collections may be grouped. In addition to what may be termed the natu-ral increase of the specimens, many celebrated collec-tions have been bought or pre-sented from time to time. Thus,  under vertebrate paleontology, the famous Cope col-lection of fossil 
mammals of North America has recelotly been purchased, repre-senting an expen- (Mitre of nearly dr I It

Since this view was taken the west wing has been nearly com-pleted, which alone represents an expenditure of nearly $350,000. An idea of the system of arranging the col-lections can be obtained from the view showing the hall of paleontology. Natural history is particularly well illustrated in taxidermic specimens in the world of mammals, birds and reptiles. One of the trophies of this department is the mounted skin of the elephant Tip, which impressive example of the taxidermist's

T h u s, under vertebrate paleontology, the famous Cope col-lection of f ossil mammals of North America has recently been purchased, repre-senting an expen-diture of nearly $16,000. This is but an indication of the work. From in a n y exploring and collecting ex-peditions, all or part of the finds are contributed to the in us eu in . From expeditions to Peru, Hondu-ras, Sumatra and Mexico, many unique sain p les have been re-ceived. The Peary Relief Expedition of 1894 greatly en-riched the depart-ment of mammals and birds.

richness. Another very interest-ing feature of the work is the department of public in-struction under the curatorship of Prof. Ticknor. Here numerous lectures on travel and exploration and on subjects connected with the exhibition are given to the school teachers and the public in general. The library now numbers upward of 30,000 volumes and many maps. Books treating of forestry and botany are in special request. Among the mineralogical specimens some samples of minerals are quite unique, from size and perfection. The Jesup collection of North American woods has at last received a permanent lodgment. It is proposed uow ever each of the beautifully mounted specimens of 
art confronts the visitor as he enters the building, and of whose preparation a description is given below. The president of the museum is Mr. Morris K. Jesup. The working staff of the institution includes the follow-ing names : Department of Public Instruction.—Prof. Albert S. Bickmore, curator. Departments of Geology, Mineralogy, Conchology and Marine Invertebrate Zoology.—Prof. R. P. Whit-field, curator ; L. P. Gratacap and Edmund 0. Hovey, assistant curators.

1. 111 11 the skin until it could hold no more has been abandoned, a n d. now the taxider-mist devotes his energies to per-petuating every fold and wrinkle of the skin that existed in the original animal. Our illustra-tions show differ-ent stages in the mounting of the skin of the famous elephant " Tip." T h i s somewhat famous elephant came here in 1881. embarking f r o Toulon under tht ownership of Carl Haagenbach. By him he was sold to Adam Fore-paugh, but as the animal proved too vicious for circus use, some eight or nine years after his purchase he was presented to the Central Park Museum. Tip had always been vicious and had the death of several keepers to answer for. While in the Central Park Museum he attacked his at-tendant, Snyder, nearly killing him, and the death of Tip himself was determined on. After considerable trouble a large dose of potassium cyanide was administered to him, on May 11, 1893, which killed him, at the age of twenty-three years. He was of good dimensions, 9 feet 6 inches in height and 11 feet long. It is quite usual to use some of the bones of the original skeleton in mounting animals. In Tip's case, however, the skeleton was preserved for separate mounting. Immediately after his death the skin was removed and all the flesh was dissected from the bones, and the skin after paring down was put in tan liquor. The bones were carefully prepared for mounting en squelette. For the taxidermic figure a wooden skull

A profile board of heavy plank was cut out, representing the longitudinal section of the great body. It was sus-tained by four iron bars fastened by iron straps to its sides. Close to the bars were mounted the representa-tive of the leg bones. This stage of operation is shown In Fig. 1, The wooden skull was attached to the pro-• file board, and a pair of tusks from another elephant were attached to the wooden skull. This gave the ex-temporized skeleton in part. To the profile board curved ribs were now attached, and over these laths were nailed closely together so as to give the general contour of the body. A similar process was applied to the legs, they being brought to a cylindrical shape by laths running up and down, nailed to a framework surrounding the iron supporting bars and wooden leg bones. From the skull depended a profile board repre-senting the longitudinal section of the trunk. This marked the second stage in the operation, and is shown in Fig. 2. The next step was to cover the laths with excelsior, tied, tacked or glued on, according to the circumstances. Now constant reference was made to the photographs of the living Tip and to measurements. The skin mean-while had been lying in the tan liquor for a year.. it was scraped and pared down to a manag ,61e thickness and was now tried on the excelsior covered elephant. This resulted in indicating the necessity for adding excelsior in some places and in taking it away in others. The skin was repeatedly tried on and the excelsior added or removed until the manikin was made to exactly fit the skin, which for ease of manipulation had been cut into three pieces. The excelsior covered core is shown in Fig. 3. When this fitting of the manikin was complete .a thick coating of modeling clay was applied all over the surface until the clay manikin, shown in Fig. 4, re-sulted. The skin was now slung up and placed over the model, and was sewn in place with wire. Fig. 5 shows the work in progress.. The trunk board had been pad-ded out to give the approximately cylindrical section. Glass eyes were put in position, the eyes being con-structed with great care to reproduce the colors of the true elephant's eye. After the tanning the skin was no longer the natural color. By the use of paint, varnish and some finishing touches, the proper color was re-stored to it and the true appearance of an elephant given to the whole, as shown in the final cut, Fig. 6. it now forums one of the most attractive objects in the museum, and represents a very complete embodiment of the art of taxidermy. The use (4* clay and of the elastic excelsior gives the taxidermist great, hieilit loo in reprodneing fin tho luau tirvs a patent invalid even if the question is not raised by the parties to the case. Blount Manufacturing Company v. Bardsley (U. S. C. C. A., 2d Cir.), 75 Fed., 674. Interpretation of Claims. —Where certain claims of a patent described a shaft. as connected with a piston " to operate the same," and " to operate the same and be operated thereby," but failed to show how the con-nection was made, it was held that the connection was not necessarily an attachment incapable of separation, but such a relation of parts as would produce simul-taneousness of motion between the shaft and piston, and, therefore, such claims cover a cam connection. Door Checks.—The Blount patent, No. 289,380, for door check; having a liquid regulating cylinder separated from the actuating spring and having a by-pass, has been held valid and the second claim re-stricted to the combination shown, and his patent, No. 485,357, for a door check and closer, has been held valid and claims 2 and 3 restricted to the specific combina-tions described. • American Soda Fountain Company v. Green (U. S. C. C., Pa.), 75 Fed., 680. What Constitutes a Combination.—A patent cannot be declared void because it is not a combination when the object to be attained by the apparatus would not be accomplished except by the mutual relation and the co-operation of the various parts. Soda Water Fountains.—The Whiffing patent, No. 414,279, has been held valid. Long v. Polk Manufacturing Company (U. S. C. C. A., 1st Cir.), 75 Fed., 835. Effect on Patent of New Functions.—The discovery of new uses or functions of a patented device has no effect upon the patent regardless of what the patentee may have claimed in the patent to be the functions and advantages of his invention, for the patent is on the mechanism. The discovery of a new function, therefore, cannot be used to give the patent a breadth not shown on its face. Road Vehicles.—The Long patent, No. 281,091, for an improved steering head for road vehicles has been con-strued and limited. Beach v. Inman (U. S. C. C., N. Y.), 75 Fed., 940. Effect of Prior Decisions.—When a patentee has ob-tained a final decree after years of arduous litigation, sustaining the broad claims of his patent, such decree should protect him against all intruders who seek to use the actual invention by making changes in forin to avoid the claims and speeification; the specification and claims are not to be scanned with a hostile eye after such decision. Paper Bag Machine.—The Buck reissue, No. 11,167, for a inlichineu to attach stays to the eornors of paper 1,4wsJL4 t,► first twi, claims is again sustained an4I is •• ■ ■■ cted with great, care to roproilliciel thca coiors or th., true elephant's eye. After the tanning the skin was 111► longer the natural color. By the use of paint varnish and some finishing touches, the proper color w!is n stored to it and the true appearance of an elephant, given to the whole, as shown in the final cut, Fig. 6. _It now forms one of the most attractive objects in the museum, and represents a very complete embodiment of the art of taxidermy. The use of clay and of the elastic excelsior gives the taxidermist great facilities in reproducing all the natu-ral features of an animal. The modern school of taxi-dermy is specially well illustrated in the American Mu-seum of Natural History. Thus,taking as example the walrus or the rhinoceros, it will be found that in both of these animals the large wrinkles or folds of the skin are very characteristic features. The modern school of taxidermy takes full cognizance of them, and often many hours and days of work are devoted to the final life-giving touches and reproduction of minute features. The stuffed animal is no longer a mounted skin ; it is the reproduction, of the animal itself, upon which every resource at the taxidermist's command is lavished. Recent Patent and Trade Mark Decisions. Osgood Dredge Company v. Met. Dredging Company (U. S. C. C. A., 1st Cir.), 75 Fed., 670. Combinations and Aggregations.—The general rule of law is that the conception of a combination which merely brings together two or more functions to be availed of independent of each other is an aggregation and not a combination, and there is no invention in it. Dredging Machines.—The Osgood patent, No. 257,888, for a dredging machine having a boom attached to operate either a scoop for hard soils,. or a " clam shell" bucket for soft soils, has been held void as to claims 1 and 3 because it is a mere aggregation and not a com-bination. Validity of a Patent as Affected by Prior Declara-tions of Defendant.—The fact that the defendant by advertisements and other publications has maintained the patentability of machines of the same general character as that for which he is charged with infring-ing is entitled to little weight in determining the validity of the patent, because whether the patent is valid or void is a matter of public concern and neither the in-ventor nor the infringer can be permitted to substitute his own opinions for the judgment of the court which represents the public. Expert Testimony.—An expert witness in a patent case has no right to answer any mixed question of law and fact, and it was improper for the expert to state as his opinion that a certain alleged invention belonged to that class of inventions described by the term "new article of manufacture." A Court Declaring a Patent Void on its Own Motion. —Because the court represents the public, and the validity of the patents is a matter of some public con-cern, a court has a right on its own motion to adjudge itostoll v Inman (11 H, 4 , N ), Vtql , 1110 )001►414.11s, 'V 11111 II 11111011101i i1uM 111, 1,/i.11114I IL I It4"I'Itl, 1111Itr yesirs or 'arduous lit Iv:at ion, sustaining I III' broad or his patents, Misch devroo 8114►pr►lvet, him against, nu tot niti►•m who sock tolls,' the actual invention by maki11t4. changes in it i tll to avoid the claims and specification; the ification and claims are not to be scanned with a hostile eye after such decision. Paper Bag Machine.—The Buck reissue, No. 11,167, for a machine to attach stays to the corners of paper boxes as to its first two claims is again sustained and is infringed by a machine having only differences of form and in substance. Ex parte Ernest (Commissioner's Decision), 76 O. G., 1417. Amendment to Drawing. —If the examiner thinks the proposed amendment to a drawing involves new mat-ter, the change in the drawings should not be allowed to be made until not only the question of new matter has been finally determined but whether the claims based thereon will be allowable, so that all questions may be settled at once on appeal. Rewriting the Specificati(►ii. —Although an al )1)1 ication may be confused and informal, yew if the claims can be understood from the description and drawings, action should betaken on the merits. Ex parte Stern (Commissioner's Decision), 76 0. G., 1417. Entering Amendment to Application.—Where an amendment to an application for a patent cancels some claims and amends others, the examiner cannot admit the amendment so far as it relates to the cancellation of claims and refuse to admit it so far as it relates to the amendment of claims, but must either enter or reject the amendment as a whole, so as to enable all questions to be settled by appeal. Ex parte McFarlane (Commissioner's Decision), 76 0. G., 1418. Dispute as to Ownership of Patent.—The Patent Office is not the proper place to dispute the ownership of a patent, for it has no judicial functions for the de-termination of private rights, and where the title is dis-puted the patent should be granted to the inventor, leaving the question to be determined by the courts. Pell v. Pierpoint (Commissioner's Decision), 76 0. G., 1573. The Question of Novelty in an Interference Case.— Where the question of priority has been decided with-out the suspension of an interference proceeding, the question of patentability of a claim involved in the in-terference will be considered ex parte and not inter partes by the primary examiner. Ex parte Grosselin (Commissioner's Decision), 76 0. G-., 1573.

Thierseli made the same experiment upon filly-six mice, the con-ditions being accurately determined and scientifically controlled, and with the death of fourteen mice gaVe the world more exact information about the contagion of cholera than all the cholera epidemics recorded in history. This is the scientific experiment which we are told should not be made. The antiseptic method, which we owe in so great a measure to the vivisectional experiments of Joseph Lister, is past all reasonable controversy and we may refer to it here. It has come to be used in hospitals generally, and has reduced mortality from surgical operations to one-tenth of what it was before. Any one who has seen even a few cases of antiseptic surgery will readily agree with Dr. Keen when he says : " Sir Joseph Lister has done more to save human life and diminish human suffering than any other mean of the last, fifty years." Still, Lister was obliged to leave England to vontinue experiment in his merciful work after the passage of the restrictive law in 187t1.

Should you be going to run your pipe on the top, let there be holes cast in plate, through which your gates will pass ; for, as will be seen at A, Fig. 1, your core plate is to be the covering plate. You must also cast holes over each flange for risers, as well as for the staples shown at B, Fig. 1. These staples will be cast in the core iron, as shown by broken lines at B, at such places as are needed for lifting, and, as you will perceive, will protrude through the plate when you set on your core iron. The core iron here shown is the best and easiest made of any I have ever used, being readily made by the use of a bent pricker pattern. It must be understood that in this case you need but one plate and one core iron. Before proceeding to ram your half core, let your plate be well cleaned, and then lay off the position of flanges, and make marks on edge of plate with a chisel to guide you in setting. Bed down' the core iron, and set in the studs to support core wherever needed, provision having been made of course by crossbars in the core iron A. Fig. 2, shows position of stud. Do not, as many try to do, attempt to slick up your core with the trowel after you have swept off the sand, but, what is much better, dampen the face of core and finish off with rubbing sticks ; by so doing you will pre-serve your core in shape. You must now place on the half flanges, which are made to fit the core. After squaring and securing them with spikes, prepare to lay on the thick-ness, which is done in this manner : Have a core-box 20" long and 6" wide, with good draft, the depth of the thickness of pipe. Let frame be secured to a board. Take the toughest sand you have, moisten it well, and with this make sufficient cores to co-ar the core inside the flanges.

The reason for the loose plate over the chaplet is to save trouble when bedding on the top plate. The mud between the plates becoming hard enough to resist the pressure, saves trouble. The top chaplet also remains where it is built, so that when the mould is closed there is no measuring or wedging to do. Mark your mould at the joint at such places as are not likely to be disturbed, lift off your cope and set up on stands high enough to work under. Lift out your core, first freeing it at prints, as well as digging out a little of the thickness all around ; this prevents the joint from being lifted up. After pulling off the thick-ness, and trimming, a little blacking finishes ready for the oven. In closing your mould, if you are careful in setting your bottom half in pit, you will find that core and cope will come together very readily. A plan of binding is shown at Fig. 2.

Mr. Ball has made sonic valuable improve-ments in their locomotives during the last few months. Cast-iron shaking grate bars have given place to a grate composed of ten 2-inch water bars and four 11" loose bars. The water bars are arranged in groups of two, with a loose bar intervening and dropped a little lower. Water bars are hydraulic drawn tubes, -1" thick, screwed in at one end and expanded at the other. The front end of the grate is 41" lower than the rear end, which gives perfect circulation through the boiler. The back flange bearing for the grate is dis-pensed with, and cross-bearers used to sup-port the grate. This prevents clogging of ashes in back end of grate, which, as is well known, tends to warp and break the grates. With this improved form of grate, which has been applied to five locomotives, an actual saving of fifteen per cent. of coal has been made. Mr. Ball has made the equalizers -Pf" deeper and 31" longer, so that the bolt in back end, where the hole is bored, cleaks the wheel and is easily taken out. This also makes a better riding engine. Another improve-ment is securing the front end of the cab to the boiler Ivith angle plates, well bolted. An iron foot-rest is placed on the back of the tank, and the reverse gear quadrant is sup-ported by a bracket from the back end of the boiler. The center bearing of the truck is made so the bearing extends fully across it instead of part way, and the bolt extending through it has a countersunk head, which comes flush against the outer bearing surface. This prevents the spring from getting loose. Some new locomotives will be built for this road, which will contain other improvements originated by Mr. Ball. The frame will be made heavier, and the pedestal jaws heavier. Changes will be made in plan of placing the dome on the boiler ; also in the dry pipes to brake ejector.

Mr. Ball has made sonic valuable improve-ments in their locomotives during the last few months. Cast-iron shaking grate bars have given place to a grate composed of ten 2-inch water bars and four 11" loose bars. The water bars are arranged in groups of two, with a loose bar intervening and dropped a little lower. Water bars are hydraulic drawn tubes, -1" thick, screwed in at one end and expanded at the other. The front end of the grate is 41" lower than the rear end, which gives perfect circulation through the boiler. The back flange bearing for the grate is dis-pensed with, and cross-bearers used to sup-port the grate. This prevents clogging of ashes in back end of grate, which, as is well known, tends to warp and break the grates. With this improved form of grate, which has been applied to five locomotives, an actual saving of fifteen per cent. of coal has been made. Mr. Ball has made the equalizers -Pf" deeper and 31" longer, so that the bolt in back end, where the hole is bored, cleaks the wheel and is easily taken out. This also makes a better riding engine. Another improve-ment is securing the front end of the cab to the boiler Ivith angle plates, well bolted. An iron foot-rest is placed on the back of the tank, and the reverse gear quadrant is sup-ported by a bracket from the back end of the boiler. The center bearing of the truck is made so the bearing extends fully across it instead of part way, and the bolt extending through it has a countersunk head, which comes flush against the outer bearing surface. This prevents the spring from getting loose. Some new locomotives will be built for this road, which will contain other improvements originated by Mr. Ball. The frame will be made heavier, and the pedestal jaws heavier. Changes will be made in plan of placing the dome on the boiler ; also in the dry pipes to brake ejector.

In a previous paper I stated briefly what we knew and what we did not know about elec-tricity. We have now to deal with electricity as generated by dynamo-electric machinery. The term " dynamo," in its present accepta-tion, is applied to any sort of an electric ma-chine, wherein the current generated is the result of work expended, or, in other words, a machine which converts the energy of me-chanical motion into the energy of electric currents, as, for instance, steam, water or wind power. The " dynamo" has come into general use, for the reason that it is the most economical generator of electricity. Electricity can be generated by chemical means, as in batteries, but here zinc is consumed, and there is no comparison in the question of economy be-tween the cost of coal and zinc. It is not necessary however, to enter into the question of the relative cost of generating the current by means of a dynamo or batteries. With batteries we have practically nothing to do, except in so far as relates to " storage batteries," and of them later on. A dynamo consists, first, of the field mag-nets, which can be of cast or wrought iron. Fairly soft wrought iron has been found to give the best results. The field magnets can be per-manent magnets—that is, where the iron of the magnet is permanently magnetized—as by the touch with the loadstone or magnet, or they can be electro-magnets, which consist of a soft iron core, around which is wound an insulated copper wire. Fig. 1 shows a perma-nent magnet. Fig. 2 shows an electro-magnet. The iron of the core is rendered magnetic by in-duction, and the degree of magnetism depends upon the current travers-ing 1,110 coil of inHnin1,..1 

In the top space there are but few lines in the middle portion more, and the lowest still more. The degree of magnetism may be said to be proportional to the number of lines within the magnetic space. The degree to which a piece of iron can be magnetized has been determined, and that point is known as the point of saturation.

one attempting to acquire information. Even the most perfect graphic illustration will sometimes fail to convey the actual true state of the case, and it is quite impossible within the limits of such an article as this to give all the facts which have a direct bearing, without having the description assume too much the character of a text-book, and thus bore the gen-eral reader. It is, however, necessary at the outset to state the observed facts and the methods by which they are observed. The field magnets in all sorts of machines are, as a rule, mounted upon a bed-plate of cast iron, and magnetically insulated therefrom by a plate of brass or other magnetic metal. Non-mag-netic metals, while they are conductors of electricity, will not connect magnetic lines, as is the case with magnetic metals. If a plate of iron be placed across the field poles of a dynamo machine, the polar influence of the magnets will be lost, and the magnets cease to act as magnets. This fact, very simple in itself, should be remembered, as I shall prob-ably have occasion to refer to it in speaking of how to locate and handle dynamo electric machines. 

How to Build a Railroad. 
The modern way of building a railroad on nothing and making it a paying enterprise for the projectors, is well illustrated in the case of the Arkansas Central narrow gauge road costing, for the 48 miles constructed and equip-ped, less than $10,000 a mile. From the coun-ties and cities along its line the owners obtained bonds and grants to the amount of nearly $500,-000. The State gave it $160,000 for arranging that the bed could be utilized for levee pur-poses, and lent it $1,350, 000 worth of State bonds. The road was then bonded for $2,500,000, and a con-siderable amount of stock certificates issued. Then the road made default in payment of interest, and rveei vet' 5'i1l4 appointed who made unbend issue of II rid (`N for completing ********************************************************************************************************************

magnetized am or magnet, or they can be electro-magnets, which consist of a soft iron core, around which is wound an insulated copper wire. Fig. 1 shows a perma-nent magnet. Fig. 2 shows an electro-magnet. The iron of the core is rendered magnetic by in-duction, and the degree of magnetism depends upon the current travers-ing the coil of insulated wire upon the magnet. With the cessation of the current, the magnetism of an electro-magnet ceases, not entirely, how-ever—a very small amount of residual mag-netism remaining in the core. Modern practice prefers eleetro-magnets from which to form the inductor of a dynamo electric machine, for the reason that, first, the degree of magnetism can be regulated to meet differing conditions, and, secondly, that the degree of magnetism can be much intensi-fied over that of a permanent magnet, and will always be the same under the same con-ditions, whereas the strength of a permanent magnet decreases and increases under varying conditions in a purely arbitrary manner, and is often affected by slight external conditions. The majority of dynamo machines which have been introduced into use are provided with two pole pieces, to which have been given the name field poles, polar extensions, etc., and arbitrarily named north and south poles, or possibly so called for the reason that the north pole attracts the north-seeking end of a compass needle, and the south pole the opposite end. Other machines have been made with a number of pole pieces which have been variously located. Two forms are shown in Figs. 3 and 4. Fig. 3 is a six-pole machine, and Fig. 4 has a large number of poles, the latter machine being the arrange-ment generally employed for alternating cur-rents. The difference between an alternating and a continuous current will be explained in its proper place. The magnets in multipolar machines are arranged alternately north,south, INT. S.

No one ever saw a magnetic field, although its influence is appreciable, and its general fea-tures can, by means known to scientists, be practically demonstrated. The delineation by lines is a convenient method only of explain-ing the observed facts in relation to the field of force. It is unfortunate that in electricity so much must be left to the imagination of

This parallel piece proper consists of two parts, so fitted that when put together as shown in Fig. 1, they form in effect one parallel piece. Fig. 2 shows the parts sepa-rated, It will be seen that by means of the screw C, the part B can be moved along A to increase or decrease the thickness of the parallel portion. The uses to which these pieces can be put in the machine shop will be apparent to mechanics. The inventor is Fred I. Getty, Springfield, Ill.

LETILIS FROM PRACTICAL MEN. 
Machine Shop Cost and Time Accounts. Editor American Machinist : I am a constant reader of your paper ; am a subscriber through our local news depot. I have read with great interest a growing demand for better systems of time keeping, and have read Mr. Shaw's method of dealing with the subject ; also Mr. Metcalf's in the March 17th issue. I shall not criticize either much, but wish to add my way to the general fund of knowledge. We keep a book for all orders, and in this is recorded every order taken, no matter how small—as, a piece of steam pipe or a 5" bolt, or anything coming our way ; and opposite this order is placed the number, as No. 4,728, for instance, and read consecutively from one to 10,000, and then commencing at one again. The order taken is by number given all over the shop. No man knows the name of the party order-ing the work. The workman has a " ticket" that the foreman issues to him, that states just what is wanted, and he is not allowed to do anything excepting what the ticket calls for. For instance, John Jones orders a gear and shaft, and gives directions as to the details, all of which are recorded in the order book. Then a ticket is issued to the pattern shop for the gear, and the pattern goes to the foundry. Then a ticket is given the black-smith for the shaft ; the machinists get their tickets, with explanations on for the work ; and when all done the time is put on the ticket, as per the inclosed cards or tickets.

work ; they are too apt, in verbal directions, to mistake 4 for 4 or vice versa, or -a for g, or 2176 for 2-11-, all leading to expense and ill-feeling. It is too easy for a man to hear wrongly in the noise of shop work and put down in his " check book " 21u. for 2 and bore a pulley too large, or 1R for 111,, and then claim he is right, as that is " what I understood you to say." But this way he has the figures, and the foreman is the re-sponsible man. I find that men are apt to be too careless, and are ofttimes, as in the case of foreigners, not able to write down their work so that it is intelligible " after it gets cold," and here he has only weights and time to keep up, and it lessens the chance of mistakes. All the tickets being in, the book-keeper quickly sees the prices, weight, labor, bolts, pattern and smith shop time, and it is but a moment's work to make a charge. By filing away all tickets, we can readily refer to the ticket to get at size of bore, keyseat, length of shaft, or any other detail, in case our customer two years hence should write to send him " another gear, the same as I got on April 8, 1886." A glance at the ticket will show the foreman if a man is too long on a job or not, and he has no excuse for a mis-take. Of course, there are some classes of work needing a foreman's personal attention, and in that case only a general ticket is issued. 

so long as the material being bored is not too hard the speed of cutting matters little, so long as you keep work and drill thoroughly cool. But keeping cool means to keep the very cutting edge cool. It is the heating of this sharp edge, which soon loses its tem-per, that causes a drill or other cutting tool to give way, and therefore it must be limited in its cutting speed to prevent this, unless a means for thoroughly cooling is applied. My reason for believing that speed makes no difference, so long as heat is removed, is from the fact that in boring with this in-creased speed I bored the same amount of inches as before without sharpening the drill, and the probability is, if the soda water could be reduced to zero or lower without freezing. that this boring could be done in about thirty or thirty-five minutes, or perhaps less.

Driving Ventilating Fan. Editor American, Machinist: In answer to P. F. D., Syracuse, N.

Loosen up the boxes and put some dry plum-bago in them, examine the boxes on fan bearings also, and apply the same remedy. With proper adjustment the fan should run continuously without trouble, if it will run

Making Gear Patterns. BY F. W. BARROWS. SECOND PAPER. 
Now you come to what I consider the most important part of the whole job, spacing round the wheel. Don't try to do this with-out first putting a fine, sharp, round point on each leg of your dividers. A three or four sided point won't work well, and if the point is not central you cannot space twice around your wheel and come out the same. I think a pair of dividers with moveable points best, because you put these points in the lathe and sharpen them up nicely. Don't use a pair of dividers that are too small, because the points will stand at an angle so great that it will vary the spacing. You may test them as follows : Step off two or three spaces (to get the motion) on any straight line, then before setting down the point for the next space, mark a short arc ; step once more and move the dividers as if for another step, but simply make the point mark the space, then, turning back once, strike a second arc through the point occu-pied by the first arc. If the two arcs just touch without intersecting, your dividers are in good shape, and are large enough. If they are too small the arcs will nearly always in-tersect. Space round your wheel, being careful to set the points down exactly on the pitch line. Don't bear on too hard, just enough to keep the points from slipping. How did you come out ? I have been so fortunate as to come out right the first time, but this doesn't occur very often, I am sorry to say. If you come pretty near it perhaps you may correct the space by giving your dividers a rub on the oilstone. If you fall short rub them inside, and if you overrun rub the out-side. I have always been foolish enough to cor-rect the space by means of the spring and screw which are found on most wing dividers. I presume I have been obliged to space four or five times around the wheel, when I might have struck it right the first time by resorting to the oil stone, but after I get good points on my dividers I am anxious to keep them so, and I have always been able to come out right by means of the screw.

[Several tickets are sent by our correspond-ent, of which we publish two, which will ex-plain the system.] A cross on the ticket is to call the attention of the workman to weigh his material when first brought into the ma-chine shop, and all rough material is so weighed by the machinist first handling it, and by no other succeeding workman. Each man has a rack with two pockets in, one for finished tickets, and one , for unfinished tickets ; when through with a job, he puts his ticket in the finished pocket, and every morning the timekeeper takes away all of his finished tickets, leaving the unfinished ones until they are put in the finished pocket. The sum total of both kinds of tickets each day must be the same number of hours as is given in the time book, by the foreman, or else an inquiry is started as to reasons therefor.

Boring Deep Holes. Editor American Machinist : Since writing the article, " Deep Holes by Continuous Boring," which appeared in your issue of March 27, I have had bored a large lot of shafts of the kind illustrated, and cer-tain conditions which I did not have before enabled me to make a better record of time on this work. The best time from the time of lifting the shaft from the floor to put into the lathe until it was again laid on the floor finished was forty-three minutes, using two reamers, for reasons before stated. This may to many seem incredible, yet it is correct. The conditions above referred to on this last lot of shafts were that heretofore the shafts were bored during the hot summer months, and the hydrant water used to cool the soda water being comparatively warm, was not effectual in carrying away the heat as thoroughly as during the cold winter months, when this water is very cold, as was the case in the last lot of shafts bored, and the speed used for boring could be very much increased. For boring the 1i" hole I used a speed such as would be considered antle, under ordinary drilling, for a drill, and I believe by getting the soda water down to nearly the freezing point and keeping it that way, and forcing a r  .- thr),igh the drill in given rt.

The main shaft makes 126 revolutions per minute, on which is a 12" pulley; fan pulley 3" diameter, making 504 revolutions. This belt never slips. It is not tightly stretched. Cannot P. F. D. discard the counter-shaft and pulleys, substituting a 3r pulley for the 97 pulley on fan shaft, and belt directly from pulley on main shaft to fan pulley ? I think he would then have no further trouble. Coldwater, Mich. E. 1VIANsELL.  
A Business Weather Bureau. 
A well-known novelist and critic suggests the expediency of establishing a literary weather bureau in this country, with view to announcing the advent and activity of new writers. An adaptation of his plan might readily be made to serve the purposes of busi-ness men, as to the matter of cutting prices. Some concerns want orders tremendously at certain times, and at other times are disposed to look for a living profit. If a business -weather bureau could be established, which would give due warning of an area of very low pressure, as likely to prevail for some days over the boiler works of Jones, Smith & Co., for instance, other boiler shop proprie-tors competing with them, at such times would know when to take to the woods. After the barometer had risen enough to indicate that the firm had quit offering boilers below cost, and were disposed to do business on business principles, other and better-balaL2ed concerns might enjoy a like season of station-ary barometer and equable weather, to the manifest advantage of Jones. gi: ,D.'s stockholders. as well  as of t ray 


I have always been foolish enough to cor-rect, the space by means of the spring and screw which are found on most wing I presume I have been obliged to space four or five times around the wheel, when I might have struck it right the first time by resorting to the oil stone, but after I get good points on my dividers I am anxious to keep them so, and I have always been able to come out right by means of the screw. In spacing a rack don't try to set the divid-ers exactly by a rule, but supposing the pitch is 1A-" measure off a foot exactly, and then make your dividers cut it up into eight spaces. I suppose that you can lay off a foot with no greater error than you would make in laying off 1k", and the error would be di-vided into eight parts, so you would get your 12" laid off only one-eighth the original error too large or small. Another thing I do is to leave off the center mark on each tooth. Make your spacing marks where one side of the tooth is to be, then by setting off the thickness of the tooth you have all thelpoints necessary. Perhaps I needn't tell you not to alter the dividers you set off the pitch with until you have spaced all the wheels of the set on both sides. If they are spur wheels for bevel wheels it doesn't make so much difference, because they may be corrected in fitting up. If bevel wheels are laid out on both sides of the teeth and worked by these lines, they will be wrong in ninety-nine cases out of a hundred, and the one other which comes right is only a streak of luck. You must be very particular in squaring across the face of spur wheels, or the two wheels won't touch on but one side. Don't trust to a try square, but lay your wheel on a flat surface and use a right angle, and after making one mark, turn the round to the opposite side and mane -'anothermark. If the two lines are not parallel, the right line will bisect the space between the two. There is another way of squariir which works equally well for wheels. I will explain it in the . - FINDING PITCH OF PROPELL1 If S. J.

the bored hole for shaft to a true vertical position, then draw a circle of the same diameter as wheel to be measured; on this lay off a certain part of the whole, making it as large as possible, and have the end of bucket cover it. Now measure vertically from the points that mark the ends of the space laid off on the circle. The difference in the height of the edge of bucket at these two points will be to the pitch as the space is to the whole circle. If the space is 3, of the circumference and the difference in the two measurements is one foot, the pitch is 12'. This is only for a straight pitch. 
Auxiliary Steam Power in Sailing Vessels. 
In our June 3, 1882 issue, we noted some observations regarding this subject, in the light of hopeful experiments that were then being made. A number of sailing vessels were then being equipped with auxiliary steam power and the promoters of the experi-ments looked for results, that, without inter-ference with the usual business of steamships, would point the way to an important and profitable addition to the American merchant marine. These experiments, according to our information gathered in shipping circles, have not resulted favorably, at least so far as sup-plying sailing vessels with auxiliary steam-power in the strict sense of the phrase is concerned. For useful information on this subject, we are indebted to Mr. Henry H. Sinclair, of New York, Captain George W. Tucker, Mr. James TI. Winchester, and other gentlemen. Capt. tucker informs us that his firm • are part owners in a sailing vessel which three years ago was equipped with auxiliary steam-imwer furnished by a prominent firm of marine et 'gill° builders. The vessel was full bark-rig-god, having three masts, with yards on two of them . She registered when equipped with aux-i I iary steam, 750 tons, with carrying capacity of about 1,150 tons. Her steam-plant consisted ►1 single-acting condensing engine, K'x30" cylinder, of about 175 nominal horse-power, and two boilers. The shaft was 8" in diameter, and 21' long. The trade she en-gaged in was regular trips between the ports of Now York and Buenos Ayres, South America, with oecnsional extensions of the trig) from tlm WW1' Dort to gild from RoNario. discharging at New York, while the $50 sav-ing in towage at Buenos Ayres accrued to the charterers and not to the ship : 
SAVING BY USE OF AUXILIARY STEAM-POWER. 
Earning capacity of entire vessel, 1,150 tons, increased one-third by 30 days saved in running time, estimated worth $3,150 Saving in towage in and out of N. Y., average  60 Proportionate saving on use of steam, 2 trips to Rosario out of 5 voyages, average 5 days, estimated worth   $525 Less only cost of coal  90    Making net  Estimated saving in wages of one man at sea  Saved on hoisting in port  
      Total saving in round trip $3,845 Balance in favor of auxiliary steam per voyage of 4,i mos  778 It will be noticed that the incidental Rosario trips account for most of the saving, and that cost of repairs has not yet entered into the comparison. This result, while showing a money balance in favor of auxiliary steam, was not regarded as sufficient to offset the extended overhauling and repairs, including replacement of boilers, that were sure to come. The steam plant was therefore removed and sold, the net result of the experiment being, of course, a loss. While the auxiliary steam-power employed in this vessel proved insufficient to be of much service in bad weather or on dangerous coasts, the vessel steamed readily 150 to 165 miles a day on several occasions during a calm. It was thought the propeller resist-ance hindered the ship from half a knot to one knot per hour, according to the fordo of the breeze. In further explanation, it should be said that, while the vessel could always get its cargo promptly at New York, the South American shippers could not be induced (doubtless, in some cases, were unable) to get their cargo made up any more promptly than in the case of an ordinary sailing vessel, the average stay in the South American port being 45 days. The remark was frequently made by shippers there that time was " no great object," and that the ship was double engines, having 20" high pressure cylinder, 36" low pressure cylinder, and 30" stroke of both. Her boilers are two in number, and built after the latest Scotch pattern, being 10' 3" long and 8' diameter each. The engines and boilers were built by Neafie & Levy, of Philadelphia, have 410 nominal horse-power, and cost complete about $30,000. Under steam the coal con-sumption averages seven tons in 24 hours. It was believed that 450 tons of coal would be sufficient to run the vessel to the east coast of Africa and back, steaming on the average one-half the time. The steam department gives employment to six men, the total number of hands required on the vessel being 17. In addition to her steam plant, the Jeanie carries full power spars and canvass, having a four-masted schooner rig, with spars 90 feet long. The dimensions of the vessel are 186 feet keel, 38 feet beam and 18 feet hold. Her propeller is two bladed, with provision for placing perpendicularly when not in use While subsequent experience shows the Jeanie to be well adapted to the east African trade, the breaking out of the Zulu war and other financial troubles in that country prevented her from ever being employed in that service, and she was accordingly transferred to the trade between New York and the West Indies. Her trips are made under continuous steam, the sails being employed only as auxiliary, the course of the vessel Dever being varied in order to use them. While her owners would not have designed this vessel expressly for that service, her performance is entirely satisfactory, the vessel averaging more than two voyages to a sailing vessel's one. Had her owners proposed originally to build the Jeanie for West Indian trade, they would have augmented her steam power and given her less sail. Capt. Winchester estimates that the Jeanie'8 entire steam plant, including shaft and coal bunkers, occupies a cargo space equivalent to 1,000 barrels, worth $700 to $1,000 for the round trip to the West Indies. Even at " the present low rates for freight," the vessel makes more money for her owners than she could do under sail, in fact, making money where a sail vessel would lose it.

builder of marine engines of our western lake service, that shows conclusively that with engines of 48" stroke, and 86 revolu-tions per minute, developing 800 horse-power, the gain by jacketing was less than 2; per cent.; less than $1.25 for each twenty-four hours, and calculating the actual running time in a year, the saving was about $180. The cost of the jackets was about $500, and the repairs on them in one year was $80, leaving a very small financial gain for a vast amount of trouble. The cost of coal on the lakes is from $2, to $2.50 per ton trimmed on board, but even if it were $4.50 per ton, a steam jacket under such circumstances would make a very small saving for the ship-master. The relative proportions of the steam cyl-inders of compound engines must be fixed according to the steam pressure and average point of cut off to be used. The usual pro-portion for 100 lbs. initial pressure is 31 y to 1 in area. The old proportion for a press-lire of 90 to 100 lbs. was 4 to 1 in area, the diameter of the low pressure cylinder being generally made twice the diameter of the high pressure cylinder. Continued practice, however, developed the fact that the terminal pressure in the low pressure cylinder was too low when this pro-portion was used, calculating of course from an economical point of cut off at the high pressure cylinder; the terminal often fell below three pounds, and six pounds is low enough for the final pressure, when it is re-leased to the condenser. Where there is no jacketing, a terminal of nine pounds will show about the same result as a jacket working with a low terminal, so I believe in a moderately high average press-ure in the low pressure cylinder, as its walls are then kept warm without the use of the jacket, and this system can be used with economy up to 600 horse-power, and I think the turning point showing any decided gain by jacketing will be found on engines de-veloping more than 700 horse-power. I have referred to the marine engine fre-quently in speaking of the compound system, as this service has developed this type of engine in many forms, after it was once abandoned by the best builders of stationary or land engines, and the marine engine build-o•t4 ar(1 very far in advance of the stationary engine builders of to-day.

 ono knot per hour, according to the form, of' power furnished by IL prominent Il•in of marine engine builders. The vessel was full bark-rig-ged, having three masts, with yards on two of them . She registered when equipped with aux-iliary steam, 750 tons, with carrying capacity of about 1,150 tons. Her steam-plant consisted of a direct single-acting condensing engine, 18"x30" cylinder, of about 175 nominal horse-power, and two boilers. The shaft was 8" in diameter, and 21' long. The trade she en-gaged in was regular trips between the ports of New York and Buenos Ayres, South America, with occasional extensions of the trip from the latter port to and from Rosario, about 200 miles further up the Uruguay River. Kerosene oil, chairs and lumber were among the chief articles of freight out of New York, while hides formed an important Hein in the return cargo. In all, five round trips were made, the Rosario trip being added to two of them. Capt. Tucker says his running time for ten passages averaged 44 to 45 days, making three months running time for the round trip, with about six weeks additional spent in port, the entire voyage averaging 4 months, though one voyage recorded the ex-ceptional time of 3 months. The steam was only used when there was not wind enough for the sails, this occurring mostly in the tropics. Capt. Tucker believes the Buenos Ayres trade includes sufficient use for auxiliary steam to make it a very fair test for that method. On this basis, as compared with subsequent performances of the same vessel, after removal of her machinery, the expense of maintaining her auxiliary steam-power is summed up as follows, without charging anything to repairs :

Against this should be set the following, no living being made in lighterage, loading or 
the breeze. In further explanation, it should be said that, while the vessel could always get its cargo promptly at New York, the South American shippers could not be induced (doubtless, in some cases, were unable) to get their cargo made up any more promptly than in the case of an ordinary sailing vessel, the average stay in the South American port being 45 days. The remark was frequently made by shippers there that time was " no great object," and that the ship was " the cheapest storehouse" they could find for their goods, their custom being to make drafts on consi2nees for the value of shipments as soon as made. This, in fact, appears to have been the chief cause of the virtual failure of the steam plant to render its use profitable. It is not doubted that the auxiliary steam would have been retained had its advantages at sea been supplemented on land by the facilities which were freely accorded to regular " steam-ers." This serious disadvantage was often further complicated by the impatience of con-signees in New York, who, misled by the words " auxiliary steam," looked upon the vessel as a " steamer," and expected steamer speed. Nor would South American shippers, while usually willing to accord the preference at the same rates, consent to allow the vessel any better than sailing vessel rates. As a matter of opinion merely, Capt. Tucker thinks schooner rigging would be preferabi for a vessel equipped with auxiliary steam. I to also thinks increasing the size of the vessel would be advantageous, thereby making the steam machinery occupy relatively less space. 
EQUAL STEAM AND SAIL POWER. An experiment of quite a different kind is found in the experience of the Jeanie, owned by J. H. Winchester & Co., of New York, the vessel having substantially what may be termed equal steam and sail power. During several years this firm had occasion to dis-patch a vessel every two months around the Cape of Good Hope to ports on the south-east coast of Africa. The trade being pros-perous, the firm concluded it would support two steam vessels, and the Jeanie was built with This end in view. Her registered ton-nage is 1,075, and her carrying capacity 1,600 tons, her steam equipment being sufficient to affoe full load in smooth water, with-out tf s a speed cr nine knots an them ' hour, nro-kicIPO )91-v;

Even at " the present low rates for freight," the vessel makes more money for her owners than she could do under sail, in fact, making money where a sail vessel would lose it. While her owners would not consider such a vessel suited to the trade between New York and California, they believe she would be as well adapted to ply between San Francisco and the Sandwich Islands, as for the East African trade for which she was built. Altogether the experience afforded by this vessel seems to indicate a more satisfactory solution of the problem of combining steam and sail for long voyages, than has yet come to our notice. 
Compound Engines for Stationary or Factory Purposes. 
BY WILLIAM H. HOFFMAN. 
THIRD PAPER. 
There are several reasons for compounding an engine ; one important reason is, that as the steam engine is a heat motor, the initial pressures can be as high as safety will permit, and lubricants will operate. There need be no trouble about any of the -,ackings, as they can all be metallic. These high pressures of steam keep it partially dry at least, and the cylinders hot, thus prevent-ing a large amount of cylinder condensa-tion. There is very little gain in compounding a steam engine if the initial steam pressure is to be below 85 lbs. After going to the extra expense of permanently separating the boiler from the condenser by the introduction of the intermediate high pressure cylinder, we must look for most of the other gains in the increased number of expansions, and to do this we must have an initial pressure of about 100 lbs.; this pressure will insure thirteen ex-pansions with the work well taken out of the steam. In practice I have found very little gain in jacketing cylinders with a diameter less than 18 inches for the high pressure, and 30 inches for the low pressure:.,!‘ie .e small engines in their jackets lieecled„ 41.i to IMO Inn'tio-poWer, 1111(I I think theNurning point sin ing an deci(1,(1 ►gain by jacketing will be found on engines de-veloping more than 700 horse-power. I have referred to the marine engine fre-quently in speaking of the compound system, as this service has developed this type of engine in many forms, after it was once abandoned by the best builders of stationary or land engines, and the marine engine build-ers are very far in advance of the stationary engine builders of to-day. There are modern marine engines now in operation, developing from 750 to 850 horse-power, making an average of 165 revolutions per minute, receiving an initial pressure of 160 lbs., and having a piston speed of 675 feet per minute and running continuously for thirty hours with less fuel consumption than any stationary compound engine within my knowledge. Now if we should go to the stationary engine builder, with a specifica-tion covering a case like the above, and add that he must transmit this power through a shaft 8 or 9 inches in diameter, and 80 feet long, or more, he would probably say that we were asking him to build an engine under extraordinary conditions ; yet this is now con-sidered small work in the marine engine line. The marine engineers are still moving on in the perfection of the compound engine. The triple expansion system is now being in-troduced on vessels as small as 300 tons, with a decided saving in fuel over the two cylinder I compound. d t believe, however, that the three cylinder triple expansion system will show much saving on engines below 400 horse-power, but am confident that three engines working on one shaft, with cranks set at 130° give the best results as to the regularity of speed, and uniform strains on the main shaft. of the marine engine builders of this country have lately constructed boilers with shells 14 feet in diameter and calculated for a safe working pressure of 165 lbs. , and to be connected to triple expansion engines. The two vessels for the White Star Line just commenced by Messrs. Harlan & Wolffe, Belfast, Ireland, will have boilers to carry 165 lbs. of steam with perfect safety. The engines will be of the triple expansion type, and will be run at high rotative and piston speeds, being the most powerful yet dc,, signed.

Settling the Eight-hour Problem in a Machine Works. 
The eight-hour plan for shops, mills and factories has been talked about for many years. It presents no new features. The same arguments for and against eight hours as the limit of a day's labor applied ten or twenty years ago that apply to-day, except that improved mechanical processes enable workmen to produce more in a given time than they formerly could do. Efforts to bring about an eight-hour rule in manufac-tories seem to have been put forth in certain spots this spring, but no general movement in that direction is discoverable. Clearly, it could not be expected that a few establish-ments could run on eight-hours' limit, while their competitors were running ten hours. About the first of April the employes of the extensive machine works of E. P. Allis & Co., of Milwaukee, which is a representative estab-lishment, and the largest of its kind in the West, petitioned the firm that they should be permitted to work eight hours a day from May 1 for the same wages as heretofore paid for ten hours. Mr. Allis, whose special efforts in behalf of working men are known not only in his own city and State, but throughout the whole country, immediately prepared a circular addressed " to all my em-ployes," and had it printed and distributed. In it he reviews the reasons why the petition could not be granted, and does so without the least touch of imperiousness. The following extract from the circular will indicate the excellent way in which the question was dis-cussed : 
The rate of wages now paid in our works, so far as we are advised, fully equals, at least. the average of our competitors, and we shall always keep in that position, and to pay ma-terially more is a business impossibility. If I have made myself clear in this communica-tion it is that I am ready to adopt the eight-hour rule, either now or at any other time that it is desired by our employes, supple-menting the individual shortening of hours by the employment of another set of men and running sixteen hours whenever the state of trade would permit. On the subject of wages, I am compelled to decline your request for a fixed and general advance until there comes some change, now unforeseen, in the state of our trade to war-rant it. and when that comes it will be reit(Iily gritillod. It is duo to yoursolvem and to my ►el f, how,,v(ir, 10 14sty I hat, there arcs sun, minor 1,11111401H 111141 WI J11411101101 Of wages 
It has long been a subject of consideration with me in what way I could join with you in the ownership of property, and avoid the dis-asters that have seemed to follow many at-tempts at co-operation. The formation of our Allis Mutual Aid Society, two or three years ago, wherein employer and employe con-tribute equally to a fund for temporary aid, was a first step in this direction. Its success and benefit is now an assured fact. Without interfering with that Aid Society—which is only a voluntary association for temporary aid the time would seem to have come when we c, lld form a legal association for perma-nent investments with every prospect of suc-cess. During the last year I have formulated a plan for an " Allis Investment Association," in which we can also be equally interested, the details of which have been several times revised and re-written to meet suggestions by a committee of your number, and by our attorneys to ensure their legal status, and which details may be further revised in the future if found to be necessary. The sub-stance of the plan—which is all that is neces-sary here—is this : A written contract is en tered into between myself and each employe joining the association, wherein the employe agrees that a certain percentage—five per cent., more or less, as may be agreed—of his wages shall go to this investment fund, and I agree with him to invest precisely the same amount in the same fund at the same time, thus making the aggregate fund belong equally to employer and employes. This fund is to be managed by a board of directors from our works, chosen equally by yourselves and by myself, of which board I am a perma-nent member and president. In this way we have a fund in which we are equal owners, and equally responsible in its management, and secure the best judgment and greatest ability we jointly possess for the purpose. This fund, if the plan meets your approval and general adoption, is likely to be a large one in time, and its investment and use is left to the judgment of the board, and whether it is used in providing homes for members, in real estate investments, in interest-bearing securities, or in industrial works to be oper-ated in common, will be governed by the cur-rent of events, and in either case is practical co-operation. It would be extraordinary and unnatural for workmen dealt with in such a fair and open manner, with so much regard for their own welfare, to cause a strike or a lock-out. It is therefore nothing remarkable, in view of these two communications, that a meeting of employes was held April 13th, and' the ques-tions of wages and hours of labor satisfac-torily settled by the following resolution, which was signed by a eoninlittee of etil ployen 111111 by Mr. Allis and Su►erintendt.nt rtiwitt ititymihtmt 
part of the iron before it can be transmitted to the hulk of the bolt consequently a heavy 1low, drives the bolt before it and has very 1 le of the riveting effect. A heavy blow delivered upon a rivet will, by the same reasoning, cripple without upsetting it to an appreciable extent. 
Salesmen as Engineers. We have a letter from a correspondent complaining that by the representations and advice of a salesman from whom he bought an engine and boilers he has been induced to adopt an injudicious and expensive ar-rangement. He thinks salesmen who, acting as engineers, give bad advice, f h _mild be ex-posed. Our observations in this respect are that no reputable house will knowingly employ sales-men who purposely do this, and that as a rule they are in the habit of giving good advice according to the light they have. They cannot, in their own interest, afford to do otherwise. But it is a question that a buyer may well ask himself, how far he should be guided by the opinions of the man of whom he buys. And this is without reference to any question of honest intention, and, to a great extent, without reference to ability. It is hardly to be expected that a salesman can give the time necessary to a proper investiga-tion of all the points at issue, especially as after spending a good deal of time in investi-gating, some other party may make the sale. If then he were to render a bill for engineer-ing services, he would ruin his prospects as a salesman, and probably fail to get pay for his services besides. If after investigating and advising he makes a sale, it is supposed to be a fair business transaction, without margin for services. purely of an engineering charac-ter. If a salesman's hasty •judgment is taken as conclusive, we do not see but the conse-quences ought to be good-naturedly abided. by. Of course, this does not cover misrep-resentation of what he sells, but matters of judgment as to amount of power, its distribu-tion and arrangement.

On the subject of wages, I am compelled to decline your request for a fixed and general advance until there comes some change, now unforeseen, in the state of our trade to war-rant it, and when that comes it will be readily granted. It is due to yourselves and to my-self, however, to say that there are some minor changes and adjustments of wages which are contemplated, especially with the lower priced, or common laborers, whose pay we think is proportionally less than others, and to whom a small advance will be made when the pending questions are settled. Should your request be imperative at this time, it could have but one result in the present state of the trade, and that would be the early closing of our works, for they can-not be run at the loss such advance would en-tail, and I shall enter into no contest with you. Should there be any feeling on your part that this advance should be made, irre-spective of the general condition of the trade and country, it would be well for you to be seeking other places and occupations, for our works would be certainly closed as soon as the few existing and low-priced contracts could be completed, until the times and con-ditions would justify their re-opening. Having said thus much upon the subject of your petition, I will ask your indulgence for a few general remarks, for the times are critical. It is not unknown to you that my sympathies are with the laboring classes, and I have for many years been conscientiously identified with what seemed to me, and still seems, the true movement for their permanent benefit. Labor has many wrongs to be righted, but the existing state of things is the growth of centuries, and its wrongs cannot be righted in a day or a year, and if no more rapid progress could be legitimately and peaceably made, we might be satisfied if each generation should be an adNance over the pre-ceding one. To attempt to hasten the time by violence or injustice, or disregard of natural law, is to approve eimilar methods in others, and its end vain, and its re-action sure and disastrous. In our republican form of government calm deliberation and the legal ballot is a greater power than hasty action and violence, and the combined intelligent influence and vote of the labor of the country would. rule its destiny, and it is that patient waiting and in-telligent influence and vote that is its hope and safety.

It is therefore nothing remarkable, in view of these two communications, that a meeting of employes was held April 13th, and' the ques-tions of wages and hours of labor satisfac-torily settled by the following resolution, which was signed by a committee of em-ployes and by Mr. Allis and Superintendent Edwin Reynolds: Resolved, That it is the sense of this com-mittee, duly appointed by a meeting of the employes of Edw. P. Allis & Co. to settle the question of wages and hours of labor, that the best interest of the Reliance Works, both for employes and for employer, is to accept the adjustment of wages outlined by Mr. Allis, viz.: a small advance to the common laborer and an equalization to some few men who, in the opinion of our Superintendent, Mr. Reynolds, are not now paid proportion-ally to others, and also that we continue until the 1st of November upon the ten-hour plan, unless the eight-hour plan shall be earlier generally adopted, with the option at that time of adopting the eight-hour plan and eight-hour pay at the rate of wages then pre-vailing, and that we shall continue under this arrangement till at least the 1st of May, 1887, with the assurance in the meantime that the rate of wages paid us shall be equal to that paid by other establishments of the same kind and competitors of these works, and we hereby adopt the above plan for the employes of these works as a settlement of the ques-tion. We commend this logical plan of settling differences in industrial establishments to both employers and employed in every part of the country where differences are expected. It is better to discuss the whole situation freely—workmen on one hand and employers on the other—before any rupture is threatened. Then, in ninety-nine cases in a hundred, a mutually satisfactory understanding can be reached and labor troubles prevented. The starting of an investment fund is no necessary part of a settlement of the wages and hours of labor question, but in the case above noted it shows the willingness of the proprietor to aid in the advancement of all his employes.

Re vi aiding Workmen for Inventions. 
English manufacturers are very generally coming to practice the giving of rewards to their workmen for improvements in tools, or in arrangements for doing work, in sums ranging from five to one hundred dollars. This, it appears to us, is an excellent plan, and one intended to bring out the best efforts of the individual workman. He is most com-petent to devise minor improvements in work-shop processes, and if suitably rewarded could afford to give thought to these matters. English manufacturers, in instances where the invention of an employe are worthy of a patent, stand ready to furnish the means upon previously-arranged tent's. When the invention is not considered worth patenting, it is paid for, as previously ex-plained, and those who continue in their inventions are encouraged by an extra reward after their fifth successful effort. This seems to be something that could be advantageously looked after in this country.

Auxiliary Steam Power in Sailing Vessels. 
In our June 3, 1882 issue, we noted some observations regarding this subject, in the light of hopeful experiments that were then being made. A number of sailing vessels were then being equipped with auxiliary steam power and the promoters of the experi-ments looked for results, that, without inter-ference with the usual business of steamships, would point the way to an important and profitable addition to the American merchant marine. These experiments, according to our information gathered in shipping circles, have not resulted favorably, at least so far as sup-plying sailing vessels with auxiliary steam-power in the strict sense of the phrase is concerned. For useful information on this subject, we are indebted to Mr. Henry H. Sinclair, of New York, Captain George W. Tucker, Mr. James TI. Winchester, and other gentlemen. Capt. tucker informs us that his firm • are part owners in a sailing vessel which three years ago was equipped with auxiliary steam-imwer furnished by a prominent firm of marine et 'gill° builders. The vessel was full bark-rig-god, having three masts, with yards on two of them . She registered when equipped with aux-i I iary steam, 750 tons, with carrying capacity of about 1,150 tons. Her steam-plant consisted ►1 single-acting condensing engine, K'x30" cylinder, of about 175 nominal horse-power, and two boilers. The shaft was 8" in diameter, and 21' long. The trade she en-gaged in was regular trips between the ports of Now York and Buenos Ayres, South America, with oecnsional extensions of the trig) from tlm WW1' Dort to gild from RoNario. 
discharging at New York, while the $50 sav-ing in towage at Buenos Ayres accrued to the charterers and not to the ship :

SAVING BY USE OF AUXILIARY STEAM-POWER. 
Earning capacity of entire vessel, 1,150 tons, increased one-third by 30 days saved in running time, estimated worth $3,150 Saving in towage in and out of N. Y., average  60 Proportionate saving on use of steam, 2 trips to Rosario out of 5 voyages, average 5 days, estimated worth   $525 Less only cost of coal  90 
Making net  Estimated saving in wages of one man at sea  Saved on hoisting in port  Total saving in round trip $3,845 Balance in favor of auxiliary steam per voyage of 4,i mos  778 It will be noticed that the incidental Rosario trips account for most of the saving, and that cost of repairs has not yet entered into the comparison. This result, while showing a money balance in favor of auxiliary steam, was not regarded as sufficient to offset the extended overhauling and repairs, including replacement of boilers, that were sure to come. The steam plant was therefore removed and sold, the net result of the experiment being, of course, a loss. While the auxiliary steam-power employed in this vessel proved insufficient to be of much service in bad weather or on dangerous coasts, the vessel steamed readily 150 to 165 miles a day on several occasions during a calm. It was thought the propeller resist-ance hindered the ship from half a knot to one knot per hour, according to the fordo of the breeze. In further explanation, it should be said that, while the vessel could always get its cargo promptly at New York, the South American shippers could not be induced (doubtless, in some cases, were unable) to get their cargo made up any more promptly than in the case of an ordinary sailing vessel, the average stay in the South American port being 45 days. The remark was frequently made by shippers there that time was " no great object," and that the ship was " 1110 v11(411►04 storelionao" they could double engines, having 20" high pressure cylinder, 36" low pressure cylinder, and 30" stroke of both. Her boilers are two in number, and built after the latest Scotch pattern, being 10' 3" long and 8' diameter each. The engines and boilers were built by Neafie & Levy, of Philadelphia, have 410 nominal horse-power, and cost complete about $30,000. Under steam the coal con-sumption averages seven tons in 24 hours. It was believed that 450 tons of coal would be sufficient to run the vessel to the east coast of Africa and back, steaming on the average one-half the time. The steam department gives employment to six men, the total number of hands required on the vessel being 17. In addition to her steam plant, the Jeanie carries full power spars and canvass, having a four-masted schooner rig, with spars 90 feet long. The dimensions of the vessel are 186 feet keel, 38 feet beam and 18 feet hold. Her propeller is two bladed, with provision for placing perpendicularly when not in use While subsequent experience shows the Jeanie to be well adapted to the east African trade, the breaking out of the Zulu war and other financial troubles in that country prevented her from ever being employed in that service, and she was accordingly transferred to the trade between New York and the West Indies. Her trips are made under continuous steam, the sails being employed only as auxiliary, the course of the vessel Dever being varied in order to use them. While her owners would not have designed this vessel expressly for that service, her performance is entirely satisfactory, the vessel averaging more than two voyages to a sailing vessel's one. Had her owners proposed originally to build the Jeanie for West Indian trade, they would have augmented her steam power and given her less sail. Capt. Winchester estimates that the Jeanie'8 entire steam plant, including shaft and coal bunkers, occupies a cargo space equivalent to 1,000 barrels, worth $700 to $1,000 for the round trip to the West Indies. Even at " the present low rates for freight," the vessel makes more money for her owners than she could do under sail, in fact, making money where a sail vessel would lose it. While her owners would not consider such a vessel suited to the trade between New York and California, they believe she would be as adapted to ply between San lerancisco am builder of marine engines of our western lake service, that shows conclusively that with engines of 48" stroke, and 86 revolu-tions per minute, developing 800 horse-power, the gain by jacketing was less than 2; per cent.; less than $1.25 for each twenty-four hours, and calculating the actual running time in a year, the saving was about $180. The cost of the jackets was about $500, and the repairs on them in one year was $80, leaving a very small financial gain for a vast amount of trouble. The cost of coal on the lakes is from $2, to $2.50 per ton trimmed on board, but even if it were $4.50 per ton, a steam jacket under such circumstances would make a very small saving for the ship-master. The relative proportions of the steam cyl-inders of compound engines must be fixed according to the steam pressure and average point of cut off to be used. The usual pro-portion for 100 lbs. initial pressure is 31 y to 1 in area. The old proportion for a press-lire of 90 to 100 lbs. was 4 to 1 in area, the diameter of the low pressure cylinder being generally made twice the diameter of the high pressure cylinder. Continued practice, however, developed the fact that the terminal pressure in the low pressure cylinder was too low when this pro-portion was used, calculating of course from an economical point of cut off at the high pressure cylinder; the terminal often fell below three pounds, and six pounds is low enough for the final pressure, when it is re-leased to the condenser. Where there is no jacketing, a terminal of nine pounds will show about the same result as a jacket working with a low terminal, so I believe in a moderately high average press-ure in the low pressure cylinder, as its walls are then kept warm without the use of the jacket, and this system can be used with economy up to 600 horse-power, and I think the turning point showing any decided gain by jacketing will be found on engines de-veloping more than 700 horse-power. I have referred to the marine engine fre-quently in speaking of the compound system, as this service has developed this type of engine in many forms, after it was once abandoned by the best builders of stationary or land engines, and the marine engine build-o•t4 ar(1 very far in advance of the stationary engine builders of to-day.

She registered when equipped with aux-iliary steam, 750 tons, with carrying capacity of about 1,150 tons. Her steam-plant consisted of a direct single-acting condensing engine, 18"x30" cylinder, of about 175 nominal horse-power, and two boilers. The shaft was 8" in diameter, and 21' long. The trade she en-gaged in was regular trips between the ports of New York and Buenos Ayres, South America, with occasional extensions of the trip from the latter port to and from Rosario, about 200 miles further up the Uruguay River. Kerosene oil, chairs and lumber were among the chief articles of freight out of New York, while hides formed an important Hein in the return cargo. In all, five round trips were made, the Rosario trip being added to two of them. Capt. Tucker says his running time for ten passages averaged 44 to 45 days, making three months running time for the round trip, with about six weeks additional spent in port, the entire voyage averaging 4 months, though one voyage recorded the ex-ceptional time of 3 months. The steam was only used when there was not wind enough for the sails, this occurring mostly in the tropics. Capt. Tucker believes the Buenos Ayres trade includes sufficient use for auxiliary steam to make it a very fair test for that method. On this basis, as compared with subsequent performances of the same vessel, after removal of her machinery, the expense of maintaining her auxiliary steam-power is summed up as follows, without charging anything to repairs :

The remark was frequently made by shippers there that time was " no great object," and that the ship was " the cheapest storehouse" they could find for their goods, their custom being to make drafts on consi2nees for the value of shipments as soon as made. This, in fact, appears to have been the chief cause of the virtual failure of the steam plant to render its use profitable. It is not doubted that the auxiliary steam would have been retained had its advantages at sea been supplemented on land by the facilities which were freely accorded to regular " steam-ers." This serious disadvantage was often further complicated by the impatience of con-signees in New York, who, misled by the words " auxiliary steam," looked upon the vessel as a " steamer," and expected steamer speed. Nor would South American shippers, while usually willing to accord the preference at the same rates, consent to allow the vessel any better than sailing vessel rates. As a matter of opinion merely, Capt. Tucker thinks schooner rigging would be preferabi for a vessel equipped with auxiliary steam. I to also thinks increasing the size of the vessel would be advantageous, thereby making the steam machinery occupy relatively less space. 

EQUAL STEAM AND SAIL POWER. An experiment of quite a different kind is found in the experience of the Jeanie, owned by J. H. Winchester & Co., of New York, the vessel having substantially what may be termed equal steam and sail power. During several years this firm had occasion to dis-patch a vessel every two months around the Cape of Good Hope to ports on the south-east coast of Africa. The trade being pros-perous, the firm concluded it would support two steam vessels, and the Jeanie was built with This end in view.

Compound Engines for Stationary or Factory Purposes.

 
BY WILLIAM H. HOFFMAN. THIRD PAPER. 
There are several reasons for compounding an engine ; one important reason is, that as the steam engine is a heat motor, the initial pressures can be as high as safety will permit, and lubricants will operate. There need be no trouble about any of the -,ackings, as they can all be metallic. These high pressures of steam keep it partially dry at least, and the cylinders hot, thus prevent-ing a large amount of cylinder condensa-tion. There is very little gain in compounding a steam engine if the initial steam pressure is to be below 85 lbs. After going to the extra expense of permanently separating the boiler from the condenser by the introduction of the intermediate high pressure cylinder, we must look for most of the other gains in the increased number of expansions, and to do this we must have an initial pressure of about 100 lbs.; this pressure will insure thirteen ex-pansions with the work well taken out of the steam. In practice I have found very little gain in jacketing cylinders with a diameter less than 18 inches for the high pressure, and 30 inches for the low pressure:.,!‘ie .e small engines in their jackets lieecled„ 41. f

(I I think theNurning point sin ing an deci(1,(1 ►gain by jacketing will be found on engines de-veloping more than 700 horse-power. I have referred to the marine engine fre-quently in speaking of the compound system, as this service has developed thistype of engine in many forms, after it was once abandoned by the best builders of stationary or land engines, and the marine engine build-ers are very far in advance of the stationary engine builders of to-day. There are modern marine engines now in operation, developing from 750 to 850 horse-power, making an average of 165 revolutions per minute, receiving an initial pressure of 160 lbs., and having a piston speed of 675 feet per minute and running continuously for thirty hours with less fuel consumption than any stationary compound engine within my knowledge. Now if we should go to the stationary engine builder, with a specifica-tion covering a case like the above, and add that he must transmit this power through a shaft 8 or 9 inches in diameter, and 80 feet long, or more, he would probably say that we were asking him to build an engine under extraordinary conditions ; yet this is now con-sidered small work in the marine engine line. The marine engineers are still moving on in the perfection of the compound engine. The triple expansion system is now being in-troduced on vessels as small as 300 tons, with a decided saving in fuel over the two cylinder I compound. d t believe, however, that the three cylinder triple expansion system will show much saving on engines below 400 horse-power, but am confident that three engines working on one shaft, with cranks set at 130° give the best results as to the regularity of speed, and uniform strains on the main shaft. of the marine engine builders of this country have lately constructed boilers with shells 14 feet in diameter and calculated for a safe working pressure of 165 lbs. , and to be connected to triple expansion engines. The two vessels for the White Star Line just commenced by Messrs. Harlan & Wolffe, Belfast, Ireland, will have boilers to carry 165 lbs. of steam with perfect safety. The engines will be of the triple expansion type, and will be run at high rotative and piston speeds, being the most powerful yet dc,, signed. It is said these engines are something over 14,000 horse-power and yet all this energy is to be fastened to the hull of a vessel that v-"' offer anything but the rigid, foundatir' the landsman nearly always fin(' and,- 7 thi,soin,

Now measure vertically from the points that mark the ends of the space laid off on the circle. The difference in the height of the edge of bucket at these two points will be to the pitch as the space is to the whole circle.

There are modern marine engines now in operation, developing from 750 to 850 horse-power, making an average of 165 revolutions per minute, receiving an initial pressure of 160 lbs., and having a piston speed of 675 feet per minute and running continuously for thirty hours with less fuel consumption than any stationary compound engine within my knowledge. Now if we should go to the stationary engine builder, with a specifica-tion covering a case like the above, and add that he must transmit this power through a shaft 8 or 9 inches in diameter, and 80 feet long, or more, he would probably say that we were asking him to build an engine under extraordinary conditions ; yet this is now con-sidered small work in the marine engine line. The marine engineers are still moving on in the perfection of the compound engine. The triple expansion system is now being in-troduced on vessels as small as 300 tons, with a decided saving in fuel over the two cylinder I compound. d t believe, however, that the three cylinder triple expansion system will show much saving on engines below 400 horse-power, but am confident that three engines working on one shaft, with cranks set at 130° give the best results as to the regularity of speed, and uniform strains on the main shaft. of the marine engine builders of this country have lately constructed boilers with shells 14 feet in diameter and calculated for a safe working pressure of 165 lbs. , and to be connected to triple expansion engines. The two vessels for the White Star Line just commenced by Messrs. Harlan & Wolffe, Belfast, Ireland, will have boilers to carry 165 lbs. of steam with perfect safety. The engines will be of the triple expansion type, and will be run at high rotative and piston speeds, being the most powerful yet dc,, signed. It is said these engines are something over 14,000 horse-power and yet all this energy is to be fastened to the hull of a vessel that v-"' offer anything but the rigid, foundatir' the landsman nearly always fin(' and,- 7 thi,soin,

Engineering. WATER TUBE BOILER.—Charles Ed-gerton, Philadelphia, Pa. This is an improvement in high pressure boilers in which tubes are entered into the flattened side of a cylindrical drum, two sets of water tubes being connected with the drum, one for down-ward and the other for upward circulation. A series of narrow braces is arranged on the inside of the flat por-tion of the boiler between the tubes, and broad U-shaped braces are arranged in the same relation to the drum, but receiving between flanges the tubes for the downward circulation. The braces are of peculiar shape, are of one piece of metal without seam or weld, and are pressed into shape, their flat surface being very thor• oughly stayed without the use of stay bolts. They also serve the purpose of strengthening the drum longitudi-nally and in all other directions. BOILER FURNACE.—Dudley D. Flem-ing, Jersey City, N. J. This furnace is designed to con-tain many times the volume of fuel now used, and have a reduced grate area, maintaining a slower generation of the gases, by means of a regulated primary air supply and the combination therewith of water vapor. The combustible hydrogen and carbonic oxide gases are sub-jected to contact in properly constructed combustion chambers with a regulated secondary air supply, convert-ing them into water and carbonic acid gas, a reaction which is continued to the point of escape in the chim-ney. The furnace is constructed in a series of sections, to be alternately charged or cleaned, always maintaining sufficient heat to ignite the gases in contact with the se-condary air supply, or, when bituminous coal is used, to consume the carbon vapor or smoke. 
Railway Appliances. CAR COUPLING.—Thomas Pales, Bridgeport, Cal. This invention relates to couplings of the pin and link type, which may be arranged to auto-matically couple meeting cars, the uncoupling being effected from the side, so that the trainmen need not go between the cars. The drawhead has a throat above which is a slot provided with link-holding devices, while movable on a vertical axis in a horizontal recess is an arm with one end projecting into the throat to engage the top of the link, the other end of. the arm extending out-wardly. The common link and pin coupling may be readily changed into one of the improved form, and cars provided with the old couplings may be used together with such as have the improvement. METALLIC TIE. — John S. Mitchell, Greelisborough, Md.

(7052) D. L. S. says : Ill SCIENTIFIC AMERICAN of October 31, 1896, Notes and Queries column, question No. 7002. Please tell me what gold size is and how made, or where it can be obtained. How is good sizing made ? A. 1. (Oil size.) prying or boiled oil thickened with yellow ocher or calcined red ocher, and carefully reduced to the utmost smoothness by grind, ing. It is thinned with oil of turpentine. Improves by age. Used for oil gilding. 2. (Water size.) Parchment or isinglass size mixed with finely ground yellow ocher. Used in burnished or distemper gilding. 3. Place boiled oil in a stone pot and place on a gentle fire, and allow the heat to rise almost to the point of ignition, then set Lire to it, and let it burn until it is thick, then put on the cover to extinguish the flames. Strain through silk and thin with turpentine. (7053) L. J. H. says : Please give through the columns of the SCIENTIFIC AMERICAN a formula for making a cement to hold two pieces of glass together. A. The Pharmacist recommends the following as a proved recipe : Take 1 ounce of Russian isinglass, cut it in small pieces, and bruise well, in order to separate the fibers ; then add 6 ounces of warm water, and leave it in a warm place that the isinglass may dissolve, which will require from 34 to 48 hours. Evaporate this to about 3 ounces. Next dissolve V2 ounce mastic in 4 ounces of alcohol, and when this is ready, transfer the isinglass from the evap-orating dish to a tin can (an empty ether can will be found convenient), heat both solutions, and add the mas-tic solution to the isinglass in small quantities at a time, shaking the can violently after each addition. While still hot strain the liquid through muslin cloth and put up in IA ounce bottles. This cement is very valuable, and articles, such as mortars, graduates, etc., mended by it have been in use for years.

RECENTLY PATENTED INVENTIONS. 
Engineering. WATER TUBE BOILER.—Charles Ed-gerton, Philadelphia, Pa. This is an improvement in high pressure boilers in which tubes are entered into the flattened side of a cylindrical drum, two sets of water tubes being connected with the drum, one for down-ward and the other for upward circulation. A series of narrow braces is arranged on the inside of the flat por-tion of the boiler between the tubes, and broad U-shaped braces are arranged in the same relation to the drum, but receiving between flanges the tubes for the downward circulation. The braces are of peculiar shape, are of one piece of metal without seam or weld, and are pressed into shape, their flat surface being very thor• oughly stayed without the use of stay bolts. They also serve the purpose of strengthening the drum longitudi-nally and in all other directions. BOILER FURNACE.—Dudley D. Flem-ing, Jersey City, N. J. This furnace is designed to con-tain many times the volume of fuel now used, and have a reduced grate area, maintaining a slower generation of the gases, by means of a regulated primary air supply and the combination therewith of water vapor. The combustible hydrogen and carbonic oxide gases are sub-jected to contact in properly constructed combustion chambers with a regulated secondary air supply, convert-ing them into water and carbonic acid gas, a reaction which is continued to the point of escape in the chim-ney. The furnace is constructed in a series of sections, to be alternately charged or cleaned, always maintaining sufficient heat to ignite the gases in contact with the se-condary air supply, or, when bituminous coal is used, to consume the carbon vapor or smoke. 
Railway Appliances. CAR COUPLING.—Thomas Pales, Bridgeport, Cal. This invention relates to couplings of the pin and link type, which may be arranged to auto-matically couple meeting cars, the uncoupling being effected from the side, so that the trainmen need not go between the cars. The drawhead has a throat above which is a slot provided with link-holding devices, while movable on a vertical axis in a horizontal recess is an arm with one end projecting into the throat to engage the top of the link, the other end of. the arm extending out-wardly. The common link and pin coupling may be readily changed into one of the improved form, and cars provided with the old couplings may be used together with such as have the improvement.

RECENTLY PATENTED INVENTIONS. 
Engineering. WATER TUBE BOILER.—Charles Ed-gerton, Philadelphia, Pa. This is an improvement in high pressure boilers in which tubes are entered into the flattened side of a cylindrical drum, two sets of water tubes being connected with the drum, one for down-ward and the other for upward circulation. A series of narrow braces is arranged on the inside of the flat por-tion of the boiler between the tubes, and broad U-shaped braces are arranged in the same relation to the drum, but receiving between flanges the tubes for the downward circulation. The braces are of peculiar shape, are of one piece of metal without seam or weld, and are pressed into shape, their flat surface being very thor• oughly stayed without the use of stay bolts. They also serve the purpose of strengthening the drum longitudi-nally and in all other directions. BOILER FURNACE.—Dudley D. Flem-ing, Jersey City, N. J. This furnace is designed to con-tain many times the volume of fuel now used, and have a reduced grate area, maintaining a slower generation of the gases, by means of a regulated primary air supply and the combination therewith of water vapor. The combustible hydrogen and carbonic oxide gases are sub-jected to contact in properly constructed combustion chambers with a regulated secondary air supply, convert-ing them into water and carbonic acid gas, a reaction which is continued to the point of escape in the chim-ney. The furnace is constructed in a series of sections, to be alternately charged or cleaned, always maintaining sufficient heat to ignite the gases in contact with the se-condary air supply, or, when bituminous coal is used, to consume the carbon vapor or smoke. 
Railway Appliances. CAR COUPLING.—Thomas Pales, Bridgeport, Cal. This invention relates to couplings of the pin and link type, which may be arranged to auto-matically couple meeting cars, the uncoupling being effected from the side, so that the trainmen need not go between the cars. The drawhead has a throat above which is a slot provided with link-holding devices, while movable on a vertical axis in a horizontal recess is an arm with one end projecting into the throat to engage the top of the link, the other end of. the arm extending out-wardly. The common link and pin coupling may be readily changed into one of the improved form, and cars provided with the old couplings may be used together with such as have the improvement.

WARM-BLAST STEAM-BOILER FURNACES A RE

port upon a series of trials of an apparatus for transferring a part of the heat of escaping clue gases to the furnace, by warming the entering air. By J. C. Hoadley. New York : John Wiley & Sons, New York. Price $1.50. The record of these trials will be found of unusual interest to engineers. As the author intimates, their value is not only in showing what can be accompli' '"), but as well in what can not be done. 1,:ose who are likely to adopt devices recommended as saving more of the heat from a boiler furnace than is lost, can, from a perusal of this book,' fortify themselves against being imposed upon by the arguments generally used in such cases. The object of the tests was to ascertain the quantity of heat escaping through the chim-ney, how much of this could be utilized, and by what means anC qt what expense, and to obtain information in any way relating to or bearing upon the subject. The problem was a difficult one, and its solution required con-siderable time, and much patient and careful work. The methods employed and the results obtained are carefully detailed and illustrated by the author, whose well-known ability for conducting experiments in this direction will give his conclusions a scientific as well as practical value. 
(199) F. P. M., Rochester, N. Y., writes :

1. I want to construct a rack and gear for a planer. How shall I determine the dimensions ? A.—In the present state of the art of building planers it would be foolish to attempt to apply figures to such a problem. A little observation will enable you to see what dimensions give satisfactory results. These dimensions have been arrived at experi-mentally, and if you begin by figures you will un-doubtedly do some costly experimenting. 2. If wrought iron or steel is used, what difference can be made in dimensions? A.—That will depend upon quality of material. Perhaps a fair estimate would be that the wrought iron or steel would be fifty per cent. stronger. 3. How can I figure the power required to run the planer light ?

A.—You can only determine this experimentally. It will depend largely upon construction. (200) J. IL, Winona, Minn., asks : 1. How many feet of heating surface is allowed per horse-power in vertical boilers where the exhaust is used to assist the draft? A.—Generally from 7 to 10. 2. What power boiler would be required for an engine with an 8y," cylinder, 300 feet piston speed, 100 lbs. boiler pressure,the engine having a slide valve with-out lap,exhaust cavity line, and line, 1" exhaust noz-zle? A.—We suppose you mean with very little lap. If you use a valve with no outside lap you will be likely to be troubled with excessive back pressure An engine, such as you describe, could probably be driven to from 25 to 30 horse-power, and as it would be the reverse of economical, the boiler should not have less than 10 feet of heating surface per horse-power. 3. In the ordinary direct-acting steam pump does steam follow full stroke ? A.—Yes, substantially. (201) 0. M., Titusville, Pa., asks : 1. Questions regarding property in patents which he should submit to some attorney skilled in patent law. 2. Can a crank be made to automatically change its length to suit varying loads, by being moved towards or from the center ? A.—It may be possible to devise a way for accomplishing this, but we do not think it would be of any practical utility.

finder this head we propose to 11 ',Hirer questions sent us, pertaining to our specialty, correctly, and according to common-sense methods. Every question, to insure any attention, must invari-ably be accompanied by the writer's name and address. If so requested, neither name, correct initials, nor loca-tion will be published. 
(194) J. S., Fremont, Ohio, writes : 1. Give me a rule for computing compound gearing for lathes ? A.—See AMERICAN MACHINIST of October 15, 1881. 2. What is pre-release ? A.—In a steam engine, if pre-release means anything it is the con-dition of exhaust brought about by the opening of the exhaust valve before the piston reaches the end of its stroke. 3. What is the British unit of heat ? A.—The quantity of heat which must be imparted to one pound of water of a temperature just above the freezing point to increase its tem-perature one degree Fahrenheit. 4. Can a rail-road machinist go on the road as engineer without other than shop practice ? A.—No. 5. How is malleable iron made ? A.—You will find a brief description of the process in the AMERICAN M ACHIN-IST of August 4, 1883. 6. What are the " proper-ties " of steam ? A.—The properties of steam, so-called, are anything which relate to its conditions, as temperature, density, etc. • (195) In Question 143, 1,3- should be sub-stituted for 3, which would give the height of the triangle 4.7694 feet, and the area 
4.7694 X 8 7.1541 feet. 2 
The contents would be 7.1541 x 16 9.836 feet. — 12 In last paragraph of Question 152, the product of 104 x 12 2-7 equals 1277.714. (196) A. L., New York, asks : how inany horse-power will a 16" double leather belt running from a 66", at 100 revolutions, to a 44" pulley, trans-mit with safety ? A.—We should say that, if pul-leys are not less than 16 feet apart, such a belt should comfortably transmit about 60 horse-power. (197) J. S. L., Allentown, Pa., writes : We have a 20" double belt running over a 60" pulley, which makes 160 revolutions per minute. This drives a 48" pulley. The belt is perpendicular. What power will it transmit ? A.—You neglect to give the distance apart of the shafts. Vertical belts are not satisfactory in their operations. We should expect that with centers 16 feet apart you could satisfactorily transmit above 60 horse-power. 2. We have a 12" double belt running over a 54" pulley, at 200 revolutions per minute, to a 32" pulley. How many horse-power will this transmit? A.—We understand the belt to be horizontal, in which case, if the centers are as far apart as in the seceding instance, this belt ought to transmit 70 , „ -)t^ ,198) "I. B., Brooklyn, N. Y., asks : What ,ze boat. ;ill a 4"x5" engine drive at a speed of nili-6 miles per hour ? A.—Such an engine will be right for a boat about 30 feet long and 6 feet beam, but the arrangement will have to be good to get a speed of utile mites,

K'nit's n►tollino shop and foundry, l'oto•boro, N. II., has been sold to a Brooklyn (N. Y.) man who will employ thirty hands on knitting machinery. Larkin & Ribbeck have erected at New Iberia, La., a building 60x150 feet, for manufacturing boilers. 
The Benedict and Burnham Company will build large additions to their tubing mill and rolling mill at Waterbury, Conn. Armitage, Herschel & Co., of Tonawanda, N. Y., contemplate extensive repairs and enlargements of their already extensive machine shops. The Coe Brass Manufacturing Company, of Tor-rington, Conn., will build a now brick and stone building, 27x150 foot in size. A co-operative boot factory at West Medway, Mass., is planned, and a canvass of the town for sub-scribers to the stock of the company is afoot. F. Scholes will put up two buildings for manufac-turing purposes at foot of Ross street, Brooklyn, N. Y. They will each be 17x50 feet and two stories high. 
It is said that all the mills at Fall River are soon to change their running time and allow but forty-11 ye minutes at noon, stopping half a day on Satur-days. 
C. B. Demarest will erect a four-story brick fac-tory on Kent avenue near Grand street, Brooklyn, N. Y. It will be 46x82 feet, and will be heated by steam. 
The Knights of Labor of Phillipsburg, N. J., have formed a co-operative stove manufacturing com-pany. They have purchased the old Robinson car-riage factory for their business. 
Work has been commenced on the Savannah, Dublin and Western Railroad in Georgia. The company will erect shops, probably at Dublin.—Baltimore Manufacturers' Record. W. E. Caldwell, of Louisville, Ky., will build a two-story metal-covered machine shop and ware-house on the south side of Main, between Brook and Floyd streets. At the annual meeting,the town of Burnham, Me., voted to give away or sell at a nominal price a val-uable water-power and several acres of land to any person who will come there and improve the same. Joshua Register's Sons, of Baltimore, have pur-chased land at the junction of the Baltimore and Ohio, Philadelphia branch, and the Union Railroad for the erection of a foundry. Mr. Thomas Henry, Jr., & Co., have commenced operations on a fine cotton-spinning mill to be erected on Trenton avenue and Tioga street, Phila-delphia. The estimated cost of the plant is $70,-000.—Textile Record. 
It is reported that W. 0. Atwood, of Guilford, Conn., has awarded the contract for building a silk mill, 110x45 feet, three stories high, with a tower 15x20, four stories high. There will also be engine, boiler and dye houses. The Railway Review, in its issuq of .h it 17, pub-lishes a number of items phi's-r=esent busi-ness of Cleveland, 01- j. Most of them reported ' than 
&
wor. 0. E. Ilughos is putting up a 111/1,011110 shop and foundry at Aberdeen, Dakota, the city having do-nated land for the purpose and use of the water from their artesian well for power, which will be supplied by a water motor. Aberdeen already has a large feed mill running from the power of the well, and soon will have their electric lights run-ning fi-om the same power. The Brown Hoisting and Conveying Machine Company, of Cleveland, Ohio, of which Mr. Alex. E. Brown, C. E., is vice-president, reports orders in hand beyond their present capacity. The company will shortly erect shops equipped with the latest and most improved machinery, that will enable them to keep pace with their present and rapidly increasing business.—Railway Review. The Taunton Gazette says " there is no doubt from what can be learned that the cotton manufac-turers of New England have pooled their issues and effected a combination for practical use in case of strikes or labor troubles of any kind. It was this that caused the cessation of trouble at the Bates mill in Maine a short time ago. There is little reason to doubt that the mills lying idle in New England to-day are drawing from the general fund to recompense them for the silence of their machinery." The 2Etna Iron Works, of Quincy will be removed to Chicago on the 1st of June. The company is now building a factory for the manufacture of archi-tectural and structual work in iron and steel for public and private buildings and other construc-tions. One building, 52x235 feet in area and two stories high, of wood and iron, is now in process of erection. A specialty will be made of a new steel casting. Both crucible and homogeneous steel will be made. One hundred and fifty men will be em-ployed. A press dispatch from Philadelphia, dated April 19, says : " Several new blast furnaces are to be built. Rolling mill capacity is to be increased to a small extent. Lower iron and steel quotations are improbable. Nails are $2.25 to $2.50, and demand active. Wrought-iron pipe mills are oversold. Steel rail mills are booking orders for the fall at thirty-five to thirty-six dollars. But little foreign iron is arriving. Contracts were placed this week for 30,000 tons of foreign material. The carriage and wagon manufacturers of the New England and Middle States are busier than they have been for three years. The demand for all kinds of ma-chinery for the West and South is heavy, and ma-chine shops are making full time, though in very few cases are their orders for delivery beyond 60 days." Plans and specifications for the location of an ex-tensive steel plant at Hammond, Ind., are nearly ready, and contracts will soon be let. There will be a nail factory, 336x120 feet, with a capacity of 1,300 kegs of nails per day ; a plate and blooming mill, 75x225 ; warehouse, 150x80 ; blacksmith and machine shop, 135x40 ; producer house, 130x50 ; keg factory, 125x40 ; bluing house, 60x30 ; boiler house and office building. These buildings will be brick, and fireproof throughout. There will be 12, ton open-hearth furnaces, one blooming mill, or nail mill, and other necessary machinery re in the steel works. These works will r• outia,A7 "e about $400,000. Operatiomv as goon as contracts are let. Cs: -

MAY 8, 1E86] _A_MERIC.A_I\T MACHINIST the bored hole for shaft to a true vertical position, then draw a circle of the same diameter as wheel to be measured; on this lay off a certain part of the whole, making it as large as possible, and have the end of bucket cover it. Now measure vertically from the points that mark the ends of the space laid off on the circle. The difference in the height of the edge of bucket at these two points will be to the pitch as the space is to the whole circle. If the space is 3, of the circumference and the difference in the two measurements is one foot, the pitch is 12'. This is only for a straight pitch. Auxiliary Steam Power in Sailing Vessels. In our June 3, 1882 issue, we noted some observations regarding this subject, in the light of hopeful experiments that were then being made. A number of sailing vessels were then being equipped with auxiliary steam power and the promoters of the experi-ments looked for results, that, without inter-ference with the usual business of steamships, would point the way to an important and profitable addition to the American merchant marine. These experiments, according to our information gathered in shipping circles, have not resulted favorably, at least so far as sup-plying sailing vessels with auxiliary steam-power in the strict sense of the phrase is concerned. For useful information on this subject, we are indebted to Mr. Henry H. Sinclair, of New York, Captain George W. Tucker, Mr. James TI. Winchester, and other gentlemen. Capt. tucker informs us that his firm • are part owners in a sailing vessel which three years ago was equipped with auxiliary steam-imwer furnished by a prominent firm of marine et 'gill° builders. The vessel was full bark-rig-god, having three masts, with yards on two of them . She registered when equipped with aux-i I iary steam, 750 tons, with carrying capacity of about 1,150 tons. Her steam-plant consisted ►1 single-acting condensing engine, K'x30" cylinder, of about 175 nominal horse-power, and two boilers. The shaft was 8" in diameter, and 21' long. The trade she en-gaged in was regular trips between the ports of Now York and Buenos Ayres, South America, with oecnsional extensions of the trig) from tlm WW1' Dort to gild from RoNario. discharging at New York, while the $50 sav-ing in towage at Buenos Ayres accrued to the charterers and not to the ship : SAVING BY USE OF AUXILIARY STEAM-POWER. Earning capacity of entire vessel, 1,150 tons, increased one-third by 30 days saved in running time, estimated worth $3,150 Saving in towage in and out of N. Y., average 60 Proportionate saving on use of steam, 2 trips to Rosario out of 5 voyages, average 5 days, estimated worth $525 Less only cost of coal 90 Making net Estimated saving in wages of one man at sea Saved on hoisting in port 4_another tesssst.

Now measure vertically from the points that mark the ends of the space laid off on the circle. The difference in the height of the edge of bucket at these two points will be to the pitch as the space is to the whole circle.

In our June 3, 1882 issue, we noted some observations regarding this subject, in the light of hopeful experiments that were then being made. A number of sailing vessels were then being equipped with auxiliary steam power and the promoters of the experi-ments looked for results, that, without inter-ference with the usual business of steamships, would point the way to an important and profitable addition to the American merchant marine. These experiments, according to our information gathered in shipping circles, have not resulted favorably, at least so far as sup-plying sailing vessels with auxiliary steam-power in the strict sense of the phrase is concerned. For useful information on this subject, we are indebted to Mr. Henry H. Sinclair, of New York, Captain George W. Tucker, Mr. James TI. Winchester, and other gentlemen. Capt. tucker informs us that his firm • are part owners in a sailing vessel which three years ago was equipped with auxiliary steam-imwer furnished by a prominent firm of marine et 'gill° builders.

LET'S START RIGHT NOW!

LET'S START RIGHT NOW
to do those things necessary to bring conditions back to normal. We've faced business stag- nation long
enough now to know what it means; so let's go- let's get started on the right track again. This business de-
depression will last just as long as the people of this country sit back and wait for something to
happen-we've got to make things happen.
We can accomplish nothing by waiting for the other fellow to start something-the chances are he is sitting
back waiting for us. We've simply got to realize that it is up to everyone to do his share, and there never
was a better time than right now to start the ball a'rolling.
Then there is another and probably a much more threatening angle to the situation. The period of
prosperity just passed has witnessed a tremendous over-expansion in practically every industry, not only
in this country, but throughout the entire civilized world. `As a consequence, today, and likely for many
years to come, the facilities for production will be greater than the powers of absorption-which means the
keenest kind of competition and the weeding out of the less stable and less progressive concerns in
each industry. Business houses today are fighting for their very existence, and those who survive will be
the ones that start now to reduce their costs and better their methods, in order to meet the keenest
competition on a fair basis. ~
How should we begin? Where should we start?


If every manufacturer in the metal working industry would start by putting his own house in order, by
replacing his old worn'-out tools with new and better machines, by weeding out bis obsolete equipment,
and installing more modern, more profitable equipment in its place, the first thing you know, we would
have better business, things would begin to move again, and industry once more would "hit the trailof
progress. We, The American Tool Works Company, have already started. Since Jan. 1921, we have weeded
out of our own plant, eighty-three machines of different kinds, and are now replacing them with the latest
and most modern tools. By this we have provided business for the foundries, orders for the steel mills,
and work for a number of men-in other words, we have gone into action in our own plant.
If you will do the same in yours, the other fellow the same in his, and so on, ad infinitum, this country
would soon forget that there was a business depression, a readjustment period or a deflation spasm. It is
up to every one of us to put our shoulder to the wheel, so let's go-a slang expression -yes-but chuck full
of meaning and good advice.
