All the shaftings were of sandal wood, and the belting of Russia leather, supplied by the family of the Czar himself. An “hydraulic annex” was also tacked on to the building. It contained a tank 60 by 180 feet, with 10 feet depth of water for fishing and bathing purposes. A portion was fenced off for the preservation and display of “The Falls,” which the hotel keepers and hackmen of Niagara kindly loaned for the occasion. The hydraulic rams and other live stock were watered here every morning, and at stated intervals during the day hydrodynamic and hydrostatic performances were given in the tank by the pupils of the “Girls’ Normal School.” The former were very unique. The consideration for the construction of this building, as per Commissioners’ report, was $542,300, including drainage, water-pipe, plumbing, and silver-plated door knobs, but exclusive of interior white-washing. This, however, was performed gratuitously by Professor Johnson of the African Commission. * * * * * Mr. John Rice, a healthful and nutritious builder, was selected to erect the beautiful HORTICULTURAL HALL, which remains a permanent ornament to our park, and an attractive target for the shots of the young idea visiting the locality. The immense expanse of glass will doubtless provide innocent amusement to many generations of young America. May they ever appreciate the kind consideration which placed the building convenient to a line of soft rocks, supplying ready-made boulders of all sizes. We believe, however, that the building is taken in at nights; we know its visitors are taken in during the day. Some idea of its vastness may be given by stating that more than 7000 acres of land are situated around it. AGRICULTURAL HALL, being of _papier maché_, inlaid with mother-in-law of pearl, was cut out by steam, and work was not commenced upon it until September, 1875. The pens for live stock adjoining the building were of steel (a favorite material in public edifices), and were a part of the contract. They were fashioned after the manner of the famous floating palace, “Adelaide Neilson,” of the Noah family. The plans were furnished by the Shemitic commission from rough drafts now in possession of the descendants of Admiral Noah. * * * * * At a late date the UNITED STATES GOVERNMENT decided to erect a few buildings, including a hospital. They thought the latter might come handy in Washington after the exhibition, for resigning officials. When we first learned that the United States had obtained 100,000 feet for their buildings, we thought it another display of persevering frugality. We imagined they desired to save a hardware bill by using the nails accompanying the material. We discovered that the feet merely meant the ground for the buildings to stand on.
