RICHEST FABRICS, JEWELRY, PORCELAINS, FURNITURE, &C.-Two great buildings fronting upon the main avenue of the Universal Exposition of 1904, covering a total area of twenty-eight acres and forming an importat part of the wonderful architectural picture, have been set aside for the rare and extensive exhibits of manufactures. Especially notable will be the foreign exhibits in these buildings, which will far surpass the beautiful

[graphic][merged small]

displays in the Palace of Varied Industries at the Paris Exposition in 1900. The nations whose exhibits attracted so much attention there are making preparations for a far more complete and elaborate presentation of their industries at St. Louis.

The unique jewelry displays will show not only the finished article but the appliances and processes for making same, arranged in such a way that the visitor may intelligently study the details of manufacture. The collection of ornamental jewelry will be the most extensive ever made, while the array of precious stones will be the most valuable ever assembled, including one of the largest as well as the rarest diamonds in existence. The art of the gold and silver smith will be presented and exemplified by workshops which will produce splendidly finished specimens on the ground.

There are few arts which have been perfected to such a high degree as that of watchmaking and clock-making both as regards the mechanism and the cases, and in this section of the Exposition every known form of clock will be shown in interesting variety, The displays of stationery, furniture, upholstery, wall paper, &c., will be without parallel.

The array of silks from this country, Europe and the East will be a brilliant spectacle in the section of Textiles.

The whole exhibit of manufactures, which includes many industries which we cannot refer to in detail, will be remarkable for its operative exhibits, and on this account as well as many others will be one of the central points of attraction and confirm the educational value of the Exposition.

versally attractive as power. Power will be the keynote of the collection and arrangement of exhibits of the Universal Exposition of 1904. There will be shown the methods and means for developing, utilizing and demonstrating power and the means for creating every variety of machinery for the generation, transmission and use of power. The engines, condensers, pumps, moving machinery and accessories making up the power plant will be installed on the main floor of Machinery Hall and occupy the entire westerly half of that building an area of something over 200,000 square feet, or about the size of an ordinary city block.

Among the many items of more than usual interest will be a 5.000 horse-power reciprocating steam engine, the weight of which, with its electric generator, is over 500 tons, and their value approximates $150,000, while the generator will be directly connected to the engine and mounted on its main shaft, which has eighty-five revolutions per minute; a 1,750 horse-power gas engine from Tegel, near Berlin, Germany; a 600 horse-power highspeed steam engine from Harrisburg, Pa.; a 750 horse-power medium-speed steam engine from Cincinnati, O.; a 1,000 horse-power slow-speed steam engine from Burlington, Ia.; a tangential water wheel from San Francisco, Cal., operated by water forced through a pipe and nozzle by a steam pump from Jeansville, Pa., at the rate of 1,200 gallons per minute and under a pressure of 300 pounds per square inch; a 3,000 horse-power gas engine from Seraing, Belgium; an 8,000 horse-power steam turbine from New York; a 5,000 horse-power steam turbine from Pittsburgh, Pa.; four 3,000 horse-power reciprocating steam engines and three 80 horse-power exciter sets. Such a line of prime movers has never before been seen, yet this is but one of the three to be installed in the western half of Machinery Hall. There will be steam engines, largely of European build, and drawn from the greatest works in England, France, Sweden and Germany; gas and oil engines, the products of the great machine shops of the world, including all types and sizes from the little one-half horse-power gas engine for domestic use to the great 8,000 horse-power steam turbine for the operation of lighting plants and trolley railroads.

The Belgian gas engine will be a wonderful achievement, for no one has ever seen a gas engine of anything like 3,000 horse-power. The same builders exhibited a gas engine of 600 horse-power at the Paris Exposition which excited more interest and comment than any other individual item at the Exposition. Here we have one with five times the capacity of the Paris engine. Its flywheel weighs thirty-four tons, has a diameter of twenty-eight feet, and its rim travels at the rate of nearly a mile and three-quarters a minute. About thirty tons of coal per day will be used in generating the gas to operate it. In the northwest corner of Machinery Hall will be seen a French reciprocating steam engine of 1,500 horse-power, with its main shaft making 330 revolutions per minute-a wonderful speed for so heavy and powerful an engine. In close proximity to Machinery Hall will be the "Steam. Gas and Fuel Building." covering an area of about 100,000 square feet, and being in itself an example of the most modern fireproof construction. Here will be hoppers for storing the 4.000 tons reserve supply of coal, and the means for automatically conveying this coal from the cars to the bunkers and from the bunkers to the furnaces and gas plants.

This power plant must engage the attention of the public by its manifest size and might: it will command the study of engineers as showing practice with which they are not familiar, and it will demand consideration by all who are financially or otherwise interested in the development and transmission of power.

MARVELS OF ELECTRICITY.

WIRELESS TELEGRAPHY AND TELEPHONY.

Electricity is the industrial life-blood of the new time. The exhibits already secured for the Palace of Electricity fully exemplify in the Universal Exposition the great strides that have been and are being made in the application of this form of energy to the uses of man. In the Palace of Electricity at this Exposition all types of machines for the generation and utilization of electrical energy will be exhibited, including dynamos and motors, both for direct and alternating currents and transformers, the use of which makes possible the long-distance transmission of energy now so common in the western part of this country. Under the same heading will be shown electric motors for railways, elevators, cranes, printing presses and the like.

Of recent years great developments have taken place in the electro-chemical industry, and several of the largest companies will contribute working exhibits, illustrating the electrolytic reduction of ores, the manufacture of nitric acid from air and various other processes, including an immense storage-battery installation as well as the newest form of secondary battery, invented by Edison. One of the latest applications of electricity falling under this group, that of the purification of water for drinking purposes, will be shown on a large scale.

Nernst, osmium and mercury vapor lamps will attract considerable attention, as their commercial development has taken place only within the last year. The intensely interesting process of the manufacture of incandescent lamps will be shown, including the "flashing' process, in which the filaments are carbonized.

Multiplex telegraph, by means of which several messages may be sent over the same wire, and mechanisms designed to transmit messages at an almost incredible rate of speed, will be shown in commercial operation.

Wireless telegraphy, possibly destined to become a powerful rival of the present system, will occupy a most prominent position among the electrical exhibits. The largest wireless-telegraph station in the world is to be established on the Exposition Grounds. From it commercial messages may be sent to many of the large Western cities.

HEY will economize labor more than any other farm implement, make your manure go from two to three times as far as when spread by hand, and result in the production of increased crops on every acre spread. The crops are increased because of the fact that the manure is thoroughly pulverized, evenly distributed, and rendered available for plant food before the fertilizing constituents in it are exhausted by the weather. We have had 25 years of

experience in Manure Spreader construction. Our machine for 1904, which we call the SUCCESS, is the latest result of our experience. It will spread any and all kinds of barnyard manure under all conditions that it can be spread by hand. The amount spread to the acre can be regulated from the seat. When the machine is discharged, the apron is automatically returned to place ready for reloading. Our new beater driving mechanism is a marvel of simplicity. We have done away with shipper levers, clutch pinions, and other complicated devices for throwing the machine into gear. The throw in and out of gear is absolute, which cannot be said of any other Spreader on the market. It will also spread lime, plaster, ashes, and commercial fertilizers. With ordinary equipments it spreads broadcast. With the drill attachment the fertilizers can be distributed in rows. Made in four sizes.

THE WHOLE THING 200 EGGS A YEAR PER HEN.

IN A NUTSHELL."

[ocr errors]
[graphic]

The third edition of the book, "200 Eggs a Year Per Hen," is now ready. Revised, enlarged, and in part rewritten. 80 pages. Contains among other things the method of feeding by which Mr. S. D. Fox, of Wolfboro, N. H., won the prize of $100 in gold offered by the manufacturers of a well-known condition powder for the best egg record during the Winter months. Simple as a, b, c-and yet we guarantee it to start hens to laying earlier, and to induce them to lay more eggs than any other method under the sun. The book also contains recipe for egg food and tonic used by Mr. Fox, which brought him in one Winter day 68 eggs from 72 hens, and for five days in succession from the same flock 64 eggs a day. Mr.E. F. Chamberlain, of Wolfboro, N. H., says: "By following the methods outlined in your book, I obtained 1,496 eggs from 91 R. I. Reds in the month of January, 1902." From 14 pullets picked at random out of a farmer's flock the author got 2,999 eggs in one year-an average of over 214 eggs apiece. It has been my ambition in writing "200 Eggs a Year Per Hen" to make it the standard book on egg production and profits in poultry. Tells all there is to know, and tells it in a plain, common-sense way. Price, 50 cents, or with a year's subscription, 60c.; or given as a premium for four yearly subscriptions to the American Poultry Advocate at 25c. each.

Our Paper is handsomely illustrated, 32 to 64 pages, 25 cents per year. 4 months' trial, 10 cents. SAMPLE FREE,

AMERICAN POULTRY ADVOCATE, 2 Wesleyan Block, Syracuse, N. Y.

At present several noted inventors are turning their attention to wireless telephony. Some of the methods for obtaining this result will be demonstrated and an opportunity afforded visitors to test their working.

PALATIAL TRANSPORTATION LOCOMOTIVE TESTS.-Transportation is the life of modern civilization. It is the circulatory system, without which high social developments could not have been reached, and the stoppage of which would cause stagnation and decay.

Modern methods of transportation, which have revolutionized the entire world, had their inception after the event the centennial of which is to be celebrated by the Louisiana Purchase Exposition this year. The vast territory purchased by the United States in 1803 is now the heart of the Republic. That it has become so rich and powerful, a seat of empire in one century, is due to the railway and the steamship and their congeners. In 1803 the means of transportation in the Louisiana Territory were of the crudest kind, principally the flat-boat and the pack-horse. To-day the same territory has 65,000 miles of railway, its rivers are traversed by great fleets, and the telegraph, telephone and trolley wires are weaving a close network over its entire surface. The unceasing purpose" of progress has had no better exemplification.

The exhibits in the Palace of Transportation will show the most advanced practice of to-day in railway building, equipment, maintenance, operation and management, and also the history of the railway as developed during the less than a century of its existence in all parts of the world.

In order to give "life" to the exhibits in this department arrangements are being made to have the wheels of the locomotives turned by compressed air. A grand central moving feature is also being planned which will be visible from all parts of the building and strike the eyes of the visitor the moment he enters any of the sixty doors of the vast structure. A steel turn-table, elevated some feet above the floor level of surrounding exhibits, will carry a mammoth locomotive weighing over 200,000 pounds-the mightiest of modern space annihilators. The wheels of the locomotive will revolve at a great speed, while the turntable, revolving more slowly by electric power, will carry the engine around and around continuously. Electric headlights on the locomotive and tender will throw their searchlight beams around the entire interior of the building. This moving trophy, emblematic of the great engineering force of civilization, bears the legend "The Spirit of the Twentieth Century." The Transportation Department will inaugurate a new departure in exposition work which is attracting world-wide interest. It will conduct during the entire term of the Exposition a series of laboratory tests of locomotives in which all of the most interesting types of modern European and American engines will be tested for comparative efficiency. The time and place are most fortunate, because foreign and domestic locomotives will be available as at no other time, and because the attendance and assistance of the leading mechanical engineers of the world are assured, thus securing to the tests a truly international character and promising an epoch-making event. These tests will be made additionally attractive by running a locomotive (or at least turning its wheels while the locomotive itself stands still) at the rate of eighty miles an hour, at a certain time each day. The locomotive laboratory will constitute a portion of the great twentieth-century exhibit to be made by the Pennsylvania Railroad system. The Baltimore and Ohio will also make a grand retrospective and contemporaneous exhibit of intense interest and educational value.

IMMENSE AUTOMOBILE EXHIBIT.

The carriage-building industry (with its concomitants, saddlery, &c.) is accorded generous consideration. Automobiles and motor vehicles, whch have come into such extensive use since the last World's Fair in this country and have given birth to and developed a vast industry, will afford one of the most popular attractions of the Exposition.

The best makers of France, Germany and Great Britain will compete with American builders, occupying a vast space with a magnificent display.

During the last decade the standing of the United States as a naval and marine power has received recognition both at home and abroad. Although known as an interior city, St. Louis is the greatest mart on one of the greatest waterways in the world. These two facts make the marine and naval exhibits objects of domestic pride and foreign study. There are few themes of more popular and scientific interest than the history of water transportation, which is graphically illustrated as never before. Peculiar interest attaches to the exhibit of the history of Mississippi River navigation which has been so closely identified with the development of the Louisiana Territory. The marine exhibits of foreign countries, of the great ocean steamship lines, of the great lakes and of all the varied minor craft of the world lend variety and interest to the scene.

AIRSHIP CONTESTS.-Recognizing the progress made toward solving the problem of aerial navigation, and the possibility, if not the probability, of remarkable achievements in the air, the Exposition has offered a grand prize of $100,000 to the airship which shall make the best record over a prescribed course, marked by captive balloons, at a speed of not less than twenty miles an hour. Quite a large number of aeronauts have announced their intention of competing. It is hoped that some of them will be able to carry off the great prize. There are other prizes for balloon races and contests of various kinds aggregating $50,000.

TWENTIETH CENTURY AGRICULTURE.-The building erected at the St. Louis Exposition for its great agricultural exhibit is the largest structure on the grounds, costing $800,000. The structure is 500 feet wide by 1,600 feet long. The first group is farm equipment and methods for improving land. This means specimens of various systems of farming, plans and models of farm buildings, the general arrangement and equipment of the farm and appliances and methods in use in agricultural engineering, viz.: machinery, draining, irrigation, and similar inprovement schemes.

Without a fair knowledge of agricultural chemistry the farmer of to-day is not fully equipped for the fight with the land. At St. Louis he will be able to compare notes, for he will see the results of study and practice about soil and water, charts, census of animals, a history of agriculture in its successive changes, and of the fluctuations in the prices of land, rents, labor, live stock, crops and animal products. Institutions, co-operative societies, communities and associations that deal with or take part in experiments and the advancement of farming will be shown.
