The recent numerous and impcrtant ap- plications of electromotive force to pur- poses of power {ransmission on a large scale is having the effect of rapidly dis- pe lirg the skepticism of engineers and power users in regard to the latent possi- naturally leads to continual progress in the improvement of appliances for the genera- tion and utilization of the curreut, among the most recent instances of which are the new generator and motor of the Western Electric Company of Chicago and New York. The machines are being built at the Chicago works, and a 300 horse-power cquipment is now being installed for use in driving the entire machinery of the | which there are six sets, are of carbon and are cross connected. An essential feature of the machine is the low speed of rotation of the armature, being for this size but 255 revolutions per minute, or but from one-half to one third of the ordi- nary speed. This, of course, effects a great Saving in power required to drive, owing ;to the reduction of frictional resistance, | Also the wear and tear of journal bearings, bilities of this medium «s compared with | ccmpany’s shops, in which the difficulties commutator and brushes is correspond- the older systems of purely mechanical of transmission by ordinary methods are ingly less. appliances, While, in the absence of any Fig. 1.—Side Elevation.

That is, it makes ‘* the wheels go round” in a satis- factory manner, and its easy adaptability to all conditions of location renders its application perfectly simple, even in cases which may present extreme difficulties in the use of any purely mechanical device. The development of the electrical system In the accompenying illustrations are shown the general construction of the two machines, together with such detail draw- ings as refer to specific improvements. The Generator. The generator, shown in Figs. 1 to 13, is of a capacity of 150 kilowatts or elec- trical horse-power. It is of ihe multipolar gramme type, compound wound for con- stant potential, or may be over com- pounded if desired. The brushes, of fore, the engine power required to drive 150 086 174.42, say 175 horse-power. The machine may be driven either by direct connection with main shaft of engine, or by belt from fly wheel, as the low speed renders the interposition of counter or jack shaft unnecessary even where engine is of the low speed type. For instance, with a 10-foot fly wheel or driving pulley and a3 foot pulley on arma- one of this size is May 4. 1893 ture shaft aspeed of 764 revolutions of engine will give the required 255 of gener- ator, which is well within the limit of the Corliss or other release-valve type. The total weight of the generators is 90 pounds per horse-power applied, or a trifle less than 105 pounds per developed horse- | power. This will make the weight of the 150 horse-power machine about 15,700 pounds. In designing the generators care was taken to render them specially adapted for such duties as involve great range in fluc- tuations of load occurring rapidly and frequently, as in case of starting and stop- ping such machines as require a large amount of power, but which are not in continuous operation. Under the most extreme conditions of fluctuation the INSULATOR Fig. 8. THE NEW regulation is perfectly automatic and so close as to require absolutely no attention to maintain the necessary uniformity of speed and current. For example, a wood- planing machine or large emery grinder requiring, say, 15 horse-power, or 10 per cent. of the full power of generator, may be started and stopped as quickly as pcs- sible without affecting the speed of either the generator itself or of the other motors connec'ed with the system. The journal bearings of the armature are provided with oil reservoirs and a simple and efficient feeding device, by which the lubrication is made automatic and per- fectly reliable, there being a glass gauge to show the quantity of oil in reservoir without the necessi!y for close inspection. As shown in Figs. 1 and 2, the machine is of compact and symmetrical design The bed plate is of deep cored ection (24 inches) giving ample strength and s\iffoes The dimensions on plan are 6 feet 10 inches by 7 feet 1 inch, and hight over THE IRON AGE. all 6 feet 74 inches. Floor space required, including overhang of pulley, is 6 feet 10 inches by 8 feet 5 inches. The drawings Figs 3 and 4 show the general construct- ive features of bed plate, housing and field- magnet cores, of which no description is necessary. The armature is shown in full detail in Figs. 5, 6, 7 and 8, the principal features of which may be briefly referred to. The shaft is of machinery steel, 6 inches diameter, to which are bolted the three brass spiders A A A carrying the peripheral coils. Each of the six arms of spiders is provided with a clamp jaw, D, by which are held the longitudinal gibs C and keys B, both of brass, by means of which the necessary adjustment of periphery is effected. The two through bolts shown in each jaw serve to clamp the gibs firmly ASBESTOS mit rhs c B \ do LOCK NUT ~ 999 armature coils. The line F is the face of commutator; the flanged portion E the armature connection, and G the sleeve or bub for holding the segments—1i20 in number—and attaching to the shaft. This is shown clearly in section in lower half of Fig. 10, all the details of construction and insulation being noted. The quadrant, Figs. 9 and 10, reeds n> description, its construction being ap- parent at a glance. The brush holders, Figs. 10 and 11, are shown in side and end elevations, and, as will be noted, each carries a set of three independently ad- justed carbons. The required pressure of the latter on the face of commutator is ob- tained by means of the spiral spring, whose tension is regulated by the thumb nut bearing on the curved horizontal lever Fig. 6.—Section of Armature Parallel with Shaft. Fig. 7.—Plan of Gib and Clamps. WESTERN ELECTRIC in the adjusted position, while that shown passing through lug in end of gib and tapped into small end of key holds the latter in p'ace. The arrangement of winding of the coils is shown in section.-in Fig. 5, one half of one of the six segments being given in de- tail. There are in all 120 coils of six wires each, laid in the outer face in two courses of three, and in the inner facein three courses of two each. The method and material for providing the necessary insulation are noted in plan in Figs, 5 and 6, the several substances employed being cotton canvas and drilling, mica, vulcanized fiber and asbestos, each being selected according to its peculiar adaptability to the require- ments «f its location. In Figs. 9, 10 and 11 the commutator quadrant and biush holders are shown. The partial transverse section of the com- mutator, in Fig. 9, shows the arrangement of segments, their insulation, and the method of connecting the wircs from the GENERATOR AND MOTOR. This arrangement gives a very elastic pressure, and admits of quick and easy ad- justment of any one of the 18 brushes forming the set. The main conductor at- tachments are made by means of the set- screwed sockets. The journal boxes are self-adjusting, of the ball bearing type, and, as previously mentioned, are self lubricating. The con- struction is shown in Figs. 12 and 13, and with the exception of a brief reference to the oiling device needs no description. It will be noted that two rings hang loosely on the journal, in positions to divide the length into equal spaces on either side of each. A sufficient portion of the upper part of the box is cut awsy to enable the ring to clear it while suspended on the journal. The lower side of this ring is immersed in the oil contained in the reser- voirs, and as the journal revolves, the ring. by reason of its greater diameter, travels more slowly, and constantly changes ‘he point of contact, at the san ¢ 1000 time carrying with it a portion of the oil received during its immersion. The holes in the top covered by caps chained to an eye in the center are for filling the reser- voirs, and also admit of observing the action of the rings. The glass 0] gauge is shown attached to right of box, Fig. 13. The box being completely inclosed in sures absolute protection from abrasion or heating from dust or grit, and at the same time prevents the throwing or leakage of oil from the constant!y flooded journals. The Motor. Like the generator, the motor is of hand- some and compact design. It is of the bi-polar drum type, hav- ing an all cast iron frame, and divided poles. There are two sets of carbon brushes. The motors are of slcw speed, that of the 10 horse-power being 650 revo- lutions per minute. The regulation is automatic, and is uniform within 5 per cent. of its rated speed. In actual use the motors have shown a commercial ef- ficiency of from 84 per cent. for 10 horse- power to 864 per cent. for 40 horse-power. The weight, complete, is 100 pounds per horse-power. The machine is made in all sizes from 4 to 40 horse-power or over.

THE NEW nal bearings are provided, similar to those of the generator previously described ; and from the fact that it requires but little, if any, attention, the motor may be placed overhead, at or near the hight of line shaft or counter which it is to drive. This is an advantage in several respects. The machine is entirely out of the way, occupy- ing no floor space, which may be required for other purposes, It enables the driving belts to be horizontal, or nearly so, and thus rejuces very considerably the fric tional load as compafed with that of a drive from the floor level.

If the projectors’ p'ans are carried out Chicago will have a new elevated railroad with branches which will constitute it the largest system yet planned, Articles of incorporation of the Grand Central Railway were filed at the office of the Secretary ot State at Springfield, Ill., on the 27th ult. They provide for a railway which will run through the diffcrent sections of Chi- cago and continue beyond the city limits in various directions through Cook County into Kane, McHenry and Boone counties, finally reaching the Wis- consin and [ndiana State lines, taking in en route adcz2n or more towns and vil- lages. One branch pssses on to Lake Geneva, Wis. Inside the corporation limits the proposed road is t> bean ele- vated structure. At the limits it is to drop to the surface. William J. Richardson, John V. Farwell, Robert Meadowcroft, Charles J. Meadow- crof', Frank R Meadowcroft, William Temple, Frank H, Starkweather, Andrew Petersen and Edmund Kaauer, all of Chi- cago, and some of them large capitalists, are the incorporatora. The capital stock is placed at $15,000,000. ato JOURNAL BOX | pee ¥ | { WOT? i RRASS + a ——~4 SLEEVE ON JOURNAL BRARING DRILLING QUADR t MICA v yr A DHILLING ae, .

The names of the men who are incorporators will be a sufficient guarantee that the Grand Central Railway Company is something tangible. We propose to build an elevated road on the North Side first of all. The people interested in the undertaking are North Siders and they May 4, 1893 THE IRON AGE. are acquainted with the transportation needs of that section. The idea is to start from a point near Kinzie street and reach the city limits and make aconnection with the north shore electric lines. We shall cross the river either by bridge or tunnel, and to the South Side elevated and the other roads which are in process of construction. The endeavor will be to form a connection with them, but our charter will give us the right to parallel the South Side system. There is a rich territory between the boulevards in the southern part of the city which may be reached. I do not say that we shal! par- allel these and other systems. We hope to make connections with them. No route has been surveyed on the North Side or elsewhere, but several have been ex- amined.” Another scheme is that of the North Chicago Rapid Transit Company, for which a license to incorporate was issued on the 22d ult. The incorporators are William Loeb, Abraham Gottlieb and Wy | Fig. 12.—Longitudinal Section, (_--- tex of the city, and is known as the Midland.

When it is desired to send a message, some beads made of a brilliant quick-burning composition are strung on a piece of quick-match, leaving intervals, and using large and small beads to make the corresponding flashes. The balloon is inflated by burning spirit, or even straw or wood. The message string is then suspended below it, a time fuse a‘- tached, and the balloon being sent up, Fig. 13.—Cross Section.

The appar- atus is described as very portable; one man can easily carry it, and with it not only can one preconcerted message be flashed, but a few words can be sent up at cne time, and those can be answered from a similar balloon from another part, upon which other balloons can be employed to continue the signaling. An eminent Erglish civil engineer has recently observed that we often hear of a speed of 90 or 100 miles being reached by English railway locomotives, but for 25 years he has ridden upon many engines and traveled on the fastest trains upon all the railways in Great Britain for the special purpose of ascertaining their rate (fspeed. Upon a few occasions, and under favorable circumstances, he has recorded the very high speed of 79 9 miles an hour, but he states that he has never been able to time a train or engine at as much as 80 miles an hou’.

The Actual Condition of the Exposi- tion, For the benefit of our readers who may be contemplating an early visit to the World’s Fair at Chicago we have caused a thorough investigation to be made of the exact status of the work of preparation. This has been done by our own representatives, who have been uninfluenced in any way and have only sought to secure actual facts. There is no question that the Chicago ex- position will far surpass, both in magni- tude and splendor, any of the international expositions thus far held. It will, there- fore, be unfortunate if a very large number of persons from distant sections of the country should visit it too early, and find- ing it in an incomplete condition should represent it to their friends and neighbors as disappointingly crude. The managers of the exposition have been obliged to contend with the most formidable obsta- cles and to overcome the most forbidding conditions from the very inception of the enterprise, not the least of which has been the very unfavorable weather of the entire month preceding the opening day. This is the period in which the grand work of two years should have come to a successful climax, the culminating point being completed build'ngs, completed exhibits and completed grounds. That they have been disappointed in accomplish- ing the work in the time specified is not to their discredit, and reproaches do not lie against them. They have done nobly, but they could not accomplish the No previous international ex- position had opened its doors with every nail driven, every display in place, grounds in perfect order and contractors out of a job, hence Chicago could not reasonably expect a different order of things to pre- vail. Exhibitors will fail to ship their goods in ample season for installation, and a thousand little delays aggregate a for- midable mass of confusion at the wind-up Chicago push is proverbial, but even Chicago push cannot prevatl in a con- test with the rest of the world and the ele- ments combined. The preparations for the exposition are not complete in many respects, and it is only just to our readers that we should say so. While visitors even now will see much that is interesting and instructive, if <h2y would get the full benefit of the elaborate preparations to be made for their entertainment they should wait until May has pretty well run its course. Detail; of the condition of the buildings and grounds the latter part of last week are as follows : Department of Machinery. In the Palace of Mechanic Arts the situ- ation is uncquivocally one of incomplete- ness. As regards the buildirg and its sev- erzl annexes there is much still to be done in the way of finishing up, though the strictly constructive portion of the work has been completed for some time. But experience teaches that this final fin- ishing up process consumes, almost inva- riably, more time than was originally allowed for the purpose, and these build- ings are no exception to the rule. The mere matter of c'earing away debris, sweeping and furbishing, to place the whole in presentable shape for the inspec- tion of visitors, is a work of days. Exte- rior painting, decorating and repairing of staff work damaged by the weather and the constant procession of teams to and from the interior, will require at least a week, though at the present tardy rate of operations it must spin out much longer, and until it is finished the unsightly scaf- folding must remain. The grounds imme- diately surrounding the buildings are in a chaotic state of litter from the piles of A ye ‘he 1002 THE IRON AGE, May 4, 1893 gravel, old lumber and unused building materials, and on the south and east sides the ground is ankle deep in loose sand still to be graded and paved, and upon which the work has been entirely discon- tinued for some time past. In the interior, the lobbies, galleries and offices may be considered in as good condition as is possible, until the entire installation of exhibits is completed and the final eleaning up can be dope. The condition of the main floor is neccs- sarily an uncertain quantity and must so eontinue until all machifes are in place on their foundations, and all pipe and belt hoks provided. Three of the original railroad tracks—situated about 4 feet below the floor level—are still uncovered for a distance of several hundred feet from the west end of buildiog and cannot be floored over so long as delayed exhibits continue to arrive. This, judging from the large amount of totally unoccupied space alotted to exhibitors, will not be completed for an indefinite time, unless the exposition authorities shall fix or en- force the limit for their admission. While there can be no doubt as to the justice of such action its effzcts might be disastrous and result in many extensive gaps, seri ously interrupting the cont‘nuity of the display and the wasting of valuable space which would have been taken gladly by other manufacturers who were desirous of making extensive exhibits. Judging from present appearances the condition of affairs in th's department will require some very energetic work for several weeks to come in order to complete the installation of exhibits and the subs: quent general finish- =H touches necessary to a creditable dis- ay. Outside of the power and electric plant and a few other conspicuous exceptions, it is no exaggeration to say that the build- ings are in a chaotic state, which would admit of but little satisfaction to pay for the difficulties of an attempt at a general inspection of exhibits. So far as this de- partment is concerned it will certainly be a great mistake for those who can devote but a limited amount of time to the ex position to make their visit earlier than the latter part of June. The display, when completed, will be most magnificent and well worthy of the attention of all who may have the opportunity of visiting the fair, but it should be seen in its normal condition and not during the transition period. Referring briefly to some of the more important details, the condition of the power plant may be shown in conncction with such application of the power as are neatly or entirely direct. The battery of boilers in main fire-room annex, together with their feed pumps and the entire sys- tem of steam, feed water, blow off and fuel oil piping, may be regarded as com- plete, and in two or three days at most, when the paving of flor and the non- eonductor pipe coverings are finished, the steam department may be seen at its best. West of main fire room, in a similar annex, there are several other boilers in course of erection, which will probably not be ready for inspection under a couple of weeks. An immense steam main, located in cellar under floor near south wall of Machinery Hall, connects with all of the boilers, and from this the distribution to the different engines is being made as rapidly as pos- sible, although in many instances the work on some of the most important en- gines is at a standstill while waiting for the Exhibition Company to give them their steam connections. As the entire system of piping for all purposes is beneath the floor, and the space in the cellar is much obstructed by foundations, posts, &c., the work is unavoidably slow, and, although pushed with the “utmost rapidity — considerable time must elapse fore all connections with steam ma- chinery are made and subsequent work on the latter completed. With the exception of a few isolated en- gines of comparatively small power:, the entire power plant is located in the space soith of the south aisle, extending almost the entire length of the Main Building and annex, a distance of over 1000 feet. Be- ginning at the east end the Worthington circulating and fire pumps have been fully ready for service for a month or more and all debris is removed so that this exhibit is entirely completed. The General Electric Company’s vertical triple expan- sion condensing engine, with its two direct connected multipolar 500 K. W. generators, will require fully a week for completion, though the work is pushed day and night. Near to it are two 150 K. W. Edison generators, completed and set, but not yet connected nor belted, There are two more cf these machines on the floor not yet on foundations. The four machines are to be driven by one 480 horse-power Ball cross compound and one Armington & Sims high-speed simple expansion engine of 400 horse-power. Both engines will require several days’ work to place them in order for continuous service. In next space are four Eddy power generators of 200 K. W. each, to be run from one single cylinder 250 horse power Phcenix engine, one tandem compound of same power and one triple expansion cross compound of 500 horse power. Both engines and generators will require several days’ work to fic them for service. In same space is 4 500 horse-power triple expansion cross compound Allis engine, upon the crank shaft of which will be placed the armature of a 500 K. W. Westinghouse railway generator. The work on this machine is apparently discontinued, although cer- tainly not more than half done, and will require a couple of weeks to put it in run- ning order. Next space contains four Matner power generators, driven by two Woodbury tandem compvund engines of 375 and 600 horse-power; also four ‘**C & C” power generators of 100 K. W., each driven by one tandem com. pound A. L. Ide engine of 225 horse power and one single cylinder high speed of same make 200 horse-power. This group is ready for service, having already been in operation. A large plant of 16 Brush dynamos for 60 arc lights each, riven by five Ball & Wood engines, aggregating 750 horse-power, has been in use for about two months on! ghtingservic:. They are ready for operation immediately. The Fraser & Chalmers 1000 horse-power triple expansion cross compound engine, for driving ene of the 10,000 light Westing- house incandescent dynamos, will probably be completed within one week. The dynam»? has been ready for the belt for some time past; but as the latter is of 72 inches width, it will require several days’ work to get it in place after the engine is ready. North of this exhibit, in same space, is the 2000 horse-power quadruple expansion engine of the Edw. P. Allis Company, which is com- pleted, as are also the two 10,000 light Westinghouse dynamos which it is to drive. As there are two 72-inch leather belts required, one of which will run on top cf the other, considerable time will be necessary for putting them on the pul- leys. West of the 1000 horse-p wer en- gine are three Wes‘inghouse automatic engines of 330 horse-power, each driving a Westinghouse exciter. These are appar ently ready for immediate service. Be tween the two large engines are located two plants which have been in continuous service for several months past. They are two ‘*C. & C.” 100 K. W. power generators driven by a McE wen tandem compound en- gine of 220 horse-power, and two exciters and Westinghouse automatic engines of 330 horse-power each. The next in order are four 1000 horse-power Westinghouse en- gines of the vertical tandem compound type, to be directly connected, each to a 10,000-light Westinghouse dynamo. The latter machines have been ready for some days; but, although the engines are not yet connected to the dynamos, and have fully a week’s work on each to place them in running order, there is little if any work being done on them. In the next spare are three dynamos of same size and make, driven respectively by a 1000 horse-power Buckeye triple ex- pansion cross-compound engine, a 1000 horse-power Atlas double tandem com- pound, and a 1000 horse-power McIntosh & Seymour double tandem compound. These engines are all delayed for want of steam connections, for which they have been waiting for a week or more. There will be fully a week’s work to complete them after these connections are made. The dynamos are about ready for the 72- inch bel.s. Following are two more of the same dynamos, each with its 1000 horse-power Westinghouse vertical-com- pound engine. Th:se machines are far behind the others, and will certainly require a couple of weeks for completion, if pushed as rapidly as possible. The next space contains 14 Fort Wayne 60 light arc dyna- mos, driven by 5 Buckeye engines, as fo!- lows : One cross-compound condensing 300 horse- power, one single cylinder 125 horse- po wer, one single cylinder high speed of 125 horse-power, one single cylinder girder frame of 190 horse-power, and one tandem- compound of 150 horsepower. These en- gines and dynamos, with the necessary switch boards, &c., are ready for immedi- ate service. West of this group are 20 Standard 50 light arc dynamos, belted from line shaft under floor, The latter is driven by 1 Erie City single cylinder high- speed, 1 Russell & Co. double tandem compound of 500 horse power, and another of same type of 200 hors: power. These machines are ready for use. The next space contains 4 Norwalk air compressors, all of which have been for some time in use, and are now being overhauled for company appearanc>. The next space is first in the annex. In it and the following one are two groups of Thomson—Houston 50-light arc dynamos. The first is composed of 16 machines, driven, through line shaft, from one Lane & Bodley cross compound 300 _horse- power, one tandem compound 300 horse- power, and one sing'e cylinder 200 horse- power, same make—all Corliss type. The second group of 10 dynamos receives power from one 500 horse power Atlas tandem compound, driving through line shaft. These machines are ready, except for the matter of clearing up the spaces occupied. Beside the latter group is one of six Excel- sior 50-light arc machines, driven by a 225 horse p»wer Boss cross compound, all of which are nearly ready for service. The last space in Main Building is occupied by two Ingersoll & Sargent duplex air com- pressors, the engines of which are of the Corliss type, cross compound. The work will require fully two weeks for comple- tion. The last space occupied by power plant contains 10 Western Electric Com- pany’s 50-light arc dynamos, driven by one Watertown double tandem compound of 250 horse power, and two Skinner single cylinder 150 horse-po wer engines. This exhibit is far from complete. Of the isolated engines throughout the building there are but few which will require any considerable time for completion. Most of these are to be used for driving the line shafting. The latter is far from com- plete, and will hardly be in condition for receiving power inside a week or 10 days. The paper-making plant to be installed at southwest corner of annex must be taken on faith, as, with the exception of some large tanks and drums, there is liitle of the material to be seen. The machine tool and wood-working machinery ex. hibits, with a few exceptions, are not even May 4, 1893 THE IRON AGE. 1003 placed in position. The pumping machin- ery, for which the large hydraulic basin has been provided, appears to be conspicu- ous principally by its absence, as but few are yet visible. Oa the north side of the building, for nearly the entire length, the space is almost impassable by reason of the paviliors, platforms and inclosures in course of construction ; while most of the exhibits are still in their boxes, or but barely un- packed. There does not appear to be any sign of anxiety expressed in the leisurely manner in which the work of installation is progressing—both foreigners and na- tives seeming to take matters quite coolly. In the pumping station the Worthington high duty horizontal duplex engine is ready for continuous service; as are also the two vertical engines, with the excep- tion of some trifling adjustments. The high speed triple expansion horizontal en- gine has not yet arrived, and will require a couple of weeks at least for erecting after it is received. The finishing up of work in the building will require about a week or ten days, and the grading and paving of the grounds surroundiog it about the same time. The Transportation Building, The Transportation Building, which is one of the very large buildings of the fair, and is intended to present a display of ex hibits which will be attractive, not only to those interested in methods of transporta- tion, but to the masses generally, is in com- paratively good shape. The inclosures of the different exhibitors are well completed, and exhibits are mainly in such shape that avery few days will enable them to be put in proper order. The opening day may not have seen everything in trim, but not many days will elapse until this build- ing needs no further touches to make it complete. The full-size model of the great steam hammer of the Bethlehem Iron Company looms up in the center of this building completely finished. Around it are a great variety of displays of all kinds of exhibits covering both land and water transportation. The annexes are full of locomotives and all kinds of passenger and freight cars, from the earliest type down to the most finished constructions of this modern era. The visitor to the Trans- portation Building will be repaid in a very short time for the trouble taken to see its exhibits. Outside of this building the roadways are not inviting; some of them are in very bad condition, having been cut up by heavy traffic teams. It would seem as though a week or two of good weather and a great deal of very hard work would be necessary to make them presentable and insure visitors sgainst wading through mud or suffering from clouds of dust. And yet it is remarkable how quickly work of this character can be done with the energy shown by the management. Passing to the north entrance in the Mines and M‘n- ing Building in the morning a great waste of rough roadway was crossed, which in the afternoon was found to be covered by a smooth sheet of asphalt which had been placed in position and smoothly rolled during the short intervening period. Look- ing at such achievements it is not safe to indulge in unfavorable predictions as to length of time necessary to get the road- ways in god shape. Administration Building and Terminal Station, The Administration Building is prac- tically completed. This is the show building of the group, having been planned on a more elaborate scale of orna mentation and for a greater display of architectural effect than any of the others. Such slight finishing touches were bein added last week as were of no specia moment, but more in the nature of house cleaning and brightening up. The great dome which covers the interior of this building, starting from the ground floor, is finished and excites the admiration of all who see it when they gaz2 upward and examine the magnificent fresco work. The Terminal Station within the grounds, intended for the accommodation of excursion trains on any of the railroads running into Chicago, is located a short distance east of the Admin‘stration Build- ing. Itis completed and ready for the accommodation of World’s Fair traffic. Between this building and the Adminis- tration Building is a broad plaza which will be macadamized, the work now being well under way. So quickly is this done by a very large force of men who have all the necessary appliances for rapid work, including heavy steam rollers, that large sections are completed in hours instead of days, as is usually the case. One of the worst pieces of roadway in the grounds is that which extends north of the Adminis- tration Building between it and the Mines and Mining Building. This looks as if it would not be presentable until after all the heavy hauling ceases and several days can be taken for its complete reconstruction. This space is rendered the more uninviting by the erection of some pavilions for vari- ous purposes, which are as yet uncovered with staff and consequently present a forlorn appearance. Mines and Mining. In the Mines and Mining Building quite a number of exhibits were finished and ready for inspection last week. Among these may be mentioned thet of Stumm Bros., the comprehensive display of New South Wales, the exhibits of the Cambria Iron Company, the Solid Steel Company, Wm. Jessop & Sons, the Gates Iron Works and the States of Missouri and Minnesota. The exhibit of Stumm Bros., who are prominent German manufacturers, was described to some extent in these c>lumns about a month since. It occupies a very conspicuous posi:ion, and is all the more conspicuous by reason of the non-com- pleted state of the exhibits surrounding it. The Cambria Iron Company make a very creditable display of their products, a prominent position being given among them to the original Keiley converter. Chief Skiff has pushed the work of instal- lation in this building with unceasing vigor, but despite his utmo:t exertions the building will not be in good shape for certainly two or three week. Some of the exhibitors have but recently begun to erect their pavilions, and the aisles were blocked by packages of goods, which could not be put in place until after the pavilions were ready to receive them. The cabioets in the galleries intended for min- eral specimens were only partially com pleted list week, and the work of unpack ing, placing and arranging the specimens will certainly take days, if not weeks of time. It is likely that everything will be in good shape here at an earlier day than is at present deemed possible, be- cause in every direction work is being prosecuted with energy and everybody is evidently hurrying to make up for lost time. The Main Building. The great building devoted to Manu factures and Liberal Arts was last week a scene of almost indescribable confusion. Everywhere there were crowds of work- men bustling and hurrying, who were at- tacking huge piles of merchandise, pack- ing boxes and all sorts of building material, trying to get matters into good shape, but making such slow progress that a day seemed to count for very little in getting things in good condition. Piles of lum ber obstructed the aisles, innumerable pavilions were only in the early stages of construction, and in very few parts of the building could an idea be obtained as to the character of the exhibits to be made in that particular section. Some of the ex- hibitors have their pavilions and exhibits in perfect shape. Conspicuous among these are the English, German, French and Belgian sections. Our own people seem to be the most dilatory. Exhibits from Chicago houses were only arriving the latter part of the week, the people nearest the fair apparently having delayed their work the longest. The Russian pa vilion, however, has just been begun. The section devoted to stoves and house furnishing goods would have been diffi- cult to fiad had it not been for the huge pavilion of the Michigan Stove Comp ny, built in the form of a cooking stove, standing 25 feet high and 30 feet long, which makes a striking lanimark in the general chaos. The visitor who enters this building this week and expects to see a complete collection of exhibits will be very much disappointed. Two weeks at the very earliest will be required, and perbaps more time than that wil! be nec- essary from present appearances. The Agricultural Building. The Agricultural Building, which is an other of the g:eat buildings of the fair, pre- sents a mere promise of what the display in it will be. Exhibitors were actively at work on their pavilions, but while some of these were completed and in full readi- ness for the opening day, others were co uparatively unfinished and numbers of them had just been begun. Packing boxes filled up tae aisles and in many cases were piled so high as to cut off the vision over a great part of the area. A month would seem to be none too much for the proper arrangement of exhibits in this building. The Electricity Building. In the Electricity Building, in which there are comparatively few exhibitors, who were therefore expected to get their exhibits in good shape at a very early day, much still remains to be done and the dis- play could by no means be considered nearly ready. Packing boxes were as con- spicuous here as in the other buildings, and days, if not a week or two, would be needed to enable the exhibitors here to get every- thing in presentable shape. Other Buildings. A ramble among the various buildings located in the north end of the grounds shows that much work yet remains to be done before they will be in a finished con- dition. The external staff work of Horti- cultural Hall plainly shows the effect of last winter’s storms. Ip some places below the window belt the staff is broken away and must be replaced. Workmen are en- gaged on the ex'erior of the building mak- ing repairs. The staff is streaked with dirt and requires painting. The floral display in the rotunda is partly finished, workmen being yet engaged in placing plants and decorations. There are few exhibits in the galleries, as workmen are finishing the decorations. In the south- east part of the building the floral exhibit is about completed, while in other parts very little has been done at installation. The Public Comfort Building is in an unfinished condition. The walls are only partly covered with staff, while floors are being laid and partitions pla tered. Puck Building shows a finished exterior. Printing presses are in position on main flor, but no exhibits are in the gallery. The staging is yet up for decorating the interior. The exterior of the Woman’s Building presents a fair appearance, as do the surrounding grounds, An inspection of the interior shows that few of the booths are finished, and harcly any ex- hibits are in position in the Main Building, booths, or gallery. 1004 THE IRON AGE, May 4, 1898 While the Illinois Building is finished, few exhibits or decorations are in position. The grounds about this building are being improved. The exterior of the Indiana Building is being finished, and the same can be said of the interior ard grounds.
