DELIGHTFULLY located near the Lake shore, south of the main Lagoon and of the area reserved for tile Foreign Nations and the several States, and east of the WOMAN'S BUILDING and of MIDWAY PLAISANCE, is the GOVERNMENT EXHIBIT BUILDING. MEXICO'S BUILDING stands just north of that of the United States, across the Lagoon. The GOVERNMENT BUILDING was designed by Architect WINDRIM, now succeeded by W. J. EDBROOKE, It is classic in style, and bears a strong resemblance to the National Museum and other Government buildings at Washington. It covers an area of 350 by 420 feet, is constructed of iron, brick and g lass, and cost $400,000. Its leading architectural feature is a central octagonal dome 120 feet in diameter and 150 feet high, the floor of which will be kept free from exhibits. The building fronts to the west, and connects on the north, by a bridge over the Lagoon, with the building of the FISHERIES EXHIBIT.

The south half of the GOVERNMENT BUILDING is devoted to the exhibits of the Post-Office Department, Treasury Department, War Department and Department of Agriculture. The north half is devoted to the exhibits of the Fisheries Commission, Smithsonian Institute and Interior Department. The State Department exhibit extends from the rotunda to the east end and that of the Department of Justice from the rotunda to the west end of the building. The allotment of space for the several department exhibits is: War Department, 23,000 square feet; Treasury, 10,500 square feet; Agricultural, 23,250 square feet; Interior, 24,000 square feet; Post-Office, 9,000 square feet; Fishery, 20,000 square feet, and Smithsonian Institute, balance of space.

The Treasury Department Exhibit is in charge of Assistant Secretary NETTLETON. He matured the plans whereby the Mint, the Coast and the Geodetic Survey, the Supervising Architect of the Treasury, the Bureau of Engraving and Printing, the Bureau of Statistics, the Life-Saving Board, the lighthouse Board and the Marine Hospital all have made exhibits.

The authorities of the Mint show not only a complete group of the coins made by the United States, but a number of the coins of foreign countries. The Supervising Architect of the Treasury shows a number of photographs of all of the public buildings of the Capital. These include not only the buildings, but they also include the parks and reservations.

The Bureau of Engraving and Printing shows manly new bills under framing, These include a sample of every bill of every denomination that the United States Government now authorizes as money.

A Life-Saving Station is built and equipped with every appliance and a regular crew goes through all life-saving manoeuvres.

Perhaps the most interesting exhibit of the whole Treasury Department is that by the Coast Survey. It includes a huge map of the United States, about 400 feet square or about the size of a square of city property. This is accurately constructed plaster of paris and is placed horizontally on the Exposition grounds with a huge covering erected over it, with galleries and pathways on the inside to allow the visitors to walk over the whole United States with out touching it. This model is built on a scale showing the exact height of mountains, the depth of the rivers and the curvature of the earth.

The Quartermaster's Department shows lay-figure officers and men of all grades in the army mounted, on foot, fully equipped in the uniform of their rank and service.

Aside from these there are nineteen figures, showing the uniforms worn during the Revolutionary War and the War of 1812 and thirty-one figures showing the uniforms in the Mexican War. A novel exhibit is that of a telephone as used on the battlefield. The heliograph, which practically annihilates distance in the matter of talking, is shown in full operation. All means of army telegraphing and signalling with the batteries, lines, cables, bombs, torches, and so forth, are shown with great elaborateness.

Capt. WHIPPLE, of the Ordnance Department, developed the plan for an exhibit of huge guns and explosives. At certain hours of the day there are regular battery drills and loading, and firing of pieces. Many of the guns used are the finest of their kind in the world.

 The exhibit of the Medical Bureau occupies a hospital built especially for its use, operated by a corps of hospital nurses and doctors.
