It is impossible here to describe in detail the architectural features or the marvellous contents of the great Machinery Hall. It is one of the most splendid structures on the grounds, measuring 850 by 500 feet in ground area, and standing at the extreme south end of the Park, just south of the Administration Building, and west from the Agricultural Building, from which it is separated by a lagoon. The general design of its interior is that of three enormous railroad train houses side by side, each spanned by trussed arches, and surrounded on all four sides by a gallery, 50 feet wide. The bulk of the machinery exhibited will be placed in this edifice and its large annex.

The building devoted to displays of Manufactures and Liberals Arts is the largest of all. Its ground area measures 1,687 by 787 feet, or nearly 31 acres. Within a gallery 50 feet wide extends around all the four sides, and projecting from this are 86 smaller galleries, 12 feet wide. These are reached from the main floor by 30 staircases, each 12 feet wide. An aisle 50 feet wide, called Columbia Avenue, extends from end to end of the building, and a transept of similar width crosses it at the centre. The main roof is of iron and glass, and its ridge pole is 150 feet from the ground. It covers an area 1,400 by 385 feet. The actual floor space of the building, including galleries, is about 40 acres. The general style of architecture is Corinthian, with almost endless arrays of columns and arches. There are four great entrances, one in the centre of each façade. These have the appearance of triumphal arches, the central opening of each being 40 feet wide and 80 feet high. Above each is a great attic story, ornamented with sculptured eagles 18 feet high. At each corner of the building is a pavilion with huge arched entrances corresponding in design with the principal portals of the building. This stately edifice faces the lake, with only lawns and promenades between it and the water. North of it is the United States Government Building, south of it the harbor and injutting lagoon, and west of it the Electrical Building and the lagoon separating it from the great island.

The Transportation exhibit is one of the most interesting of the whole display and is housed in a huge Romanesque building, standing between the Horticultural and Mining Buildings. It faces the east and commands a fine view of the lagoon and great island. Its area measures 960 by 250 feet, besides a vast annex covering 9 acres more. The principal entrance to the building is through a huge arch, very richly decorated. Within the building is treated after the manner of a Roman Basilica, with broad nave and aisles. At the centre is a cupola rising 165 feet above the ground, and reached by eight elevators. The exhibits in this building and its annex will comprise everything pertaining to transportation, including all manner of railroad engines and cars, steamboats and other vessels, coaches, cabs and carriage balloons and carrier pigeons, bicycles and baby carriages, cash conveyors for stores, pneumatic tubes, passenger and freight elevators, etc.

The United States Government Building stands near the lake shore, south of the main lagoon. Its architecture is classic, resembling the National Museum and other Government Buildings at Washington. It is made of iron, brick, and glass and measures 350 by 420 feet. At the centre is an octagonal dome, 120 feet in diameter and 150 feet high. The south half of the building is devoted to exhibits of the Post Office, Treasury, War, and Agricultural Departments. The north half is given up to the Interior Department, the Smithsonian Institute, and the Fisheries Commission. The State Department exhibit is between the rotunda and the east, and the Department of Justice between the rotunda and the west end. The rotunda itself will be kept clear of all exhibits.

The gem of all the buildings is that occupied by the Administration of the Exhibition. It stands at the west end of the great court, looking eastward, just in front of the railroad stations. It covers an area 260 feet square and consists of four pavilions, each 84 feet square, connected by a vast central dome 120 feet in diameter and 220 feet high, leaving at the centre of each façade a recess of 82 feet wide within which are the grand entrance to the building. The general design is in the style of the French renaissance. The first story is Doric, of heroic proportions, and the second Ionic. The four great entrances are each 50 feet wide and 50 feet high, deeply recessed and covered by semicircular arches. The great dome, which will be one of the most striking features in the landscape of the Exhibition, is richly gilded externally. Within it is decorated with a profusion of sculpture and paintings.

The Illinois State Building is naturally by far the finest of all the structures erected by the various States of the Union. It stands on a high terrace in one of the choicest parts of Jackson Park, commanding a splendid view of the grounds. It is 450 feet long and 160 feet wide. At the north Memorial Hall forms a wing 50 by 75 feet. At the south is another wing, 75 by 123 feet, three stories high, containing the executive offices and two large public halls. Surmounting the central portion of the building is a fine dome 72 feet in diameter and 235 feet high. The entire edifice is constructed, almost exclusively, of wood, stone, brick, and steel produced by the State of Illinois.

No sketch of the Columbian Exhibition would be complete without some mention of its principal projectors and managers. The President of the World’s Fair Columbian Commission is Thomas Wetherill Palmer, who was born at Detroit, Michigan, on June 25th, 1830. He is of New England descent and his parents were among the early settlers in Michigan. Mr. Palmer was educated at St. Clair College and the University of Michigan, and after his college days made a long pedestrian tour through Spain, thus becoming familiar with the country to which he was afterward sent as United States Minister. After some years of prosperous mercantile life in Detroit, and honorable participation in State politics he was elected United States Senator and served six years. In 1889 he was made Minister to Spain. At the first meeting of the World’s Fair Columbian Commission, held in Chicago on June 26th, 1890, he was unanimously elected President and at once entered upon the duties of the office.
