At the south side of the Agricultural Building is another vast structure, devoted principally to a Live Stock and Agricultural Assembly Hall. This is to be the common meeting-point for all persons interested in live stock and agricultural pursuits. This building contains a fine lecture-room, with a seating capacity of about 1,500, in which lectures will be delivered and conferences held on topics connected with live stock, agriculture, and allied industries. The Forestry Building stands near the Agricultural Building, and is the most unique of all the Exhibition structures. Its ground area is 200 by 500 feet. On all four sides is a veranda, the roof of which is supported by a colonnade, each column of which consists of three tree-trunks, each 25 feet long. These trunks are in their natural state, with the bark undisturbed. They were contributed by the different States and Territories of the Union, and by various foreign countries, each furnishing specimens of its most characteristic trees. The walls of the building are covered with slabs of logs with the bark removed. The roof is thatched with bark. Within, the building is finished in a great variety of woods so treated as to show, to the best advantage, their graining, their colors, their susceptibility to polish, etc. It will contain a wonderful exhibition of forest products in general, doubtless the most complete ever seen [Illustration: BEAR PIT (LINCOLN PARK).] in the world, including logs and sections of trees, worked lumber in the form of beams, planks, shingles, etc., dye-woods and barks, mosses, gums, resins, vegetable ivory, rattan, willow-ware, and wooden-ware generally, etc. There will also be a large exhibit of saw-mill and wood-working machinery, including four complete saw-mills, which will be seen in an annex attached to the Forestry Building. Close by the Forestry Building is the Dairy Building, which will contain not only a complete exhibit of dairy products, but also a dairy school, in connection with which will be conducted a series of tests for determining the relative merits of different breeds of dairy cattle as producers of milk and butter. This structure stands near the lake shore and is 95 by 200 feet in area, and two stories high. On the first floor, besides office headquarters, there is a large room devoted to exhibits of butter, and further back an operating room, in which a model dairy will be conducted. On two sides of this room are seats for 400 spectators, to witness the operations of the model dairy. In a gallery about this room will be the exhibits of cheese.
