the Supports, which elevate the box forty inches from the floor, and 

 also serve as the upright corner posts of the framework of this 

 box, whose inside dimensions, exclusive of the space over the feed 

 box, is forty-eight inches long, twenty inches wide, and thirty-four 

 inches high. The space for the feed box extends the cage box for- 

 ward another twelve inches. The sides, not including the twelve- 

 inch space allowed for the feed box, are made of two parts, the 

 lower twenty inches being of boards {G), and the space above {A) is 

 fitted with quarter-inch iron rods placed perpendicularly three inches 

 apart. The rear wall, roof, and the portion of the walls above the 

 feed box, are covered with boards. All inside exposures, for twenty 

 inches from the bottom of this box, are protected by galvanized 

 sheet iron (C), and a triangulär wooden strip {D) \s nailed around 

 the side walls just above the bottom, over which the galvanized iron 

 is bent, to direct all drippings from the sides of the cage into the 

 hopper. 



Seven inches above the screen floor, at the front of the cage, is 

 the removable feed box {G), eighteen inches long, ten inches wide, 

 and seven inches deep (inside measurements). This box is lined 

 with sheet iron, which extends as a facing over the outer portion on 

 the side next to the goat. A wall {H) of the same materials ex- 

 tends from this side of the feed box to the floor, partitioning off a 

 space from the rest of the cage, in which Utensils may be kept. 



The screen floor is specially woven from No. lo iron wire, over 

 a frame of quarter-inch iron rod, with the lengthwise Strands five 

 eighths of an inch apart; the crosswise, seven eighths of an inch 

 apart. The whole is afterwards galvanized. This floor slides in or 

 out through an opening (/) in the rear end of the cage, just large 

 enough to let the floor pass through, permitting an easy and quick 

 exchange of screens when desirable. A screen of different mesh 

 may be convenient to have on band, if the düng pellets are unusually 

 large, or become soft and tend to cling together. 



The pan {K), to catch any fodder that may be dropped in eat- 

 ing, slides under the floor screen from the side, and covers the space 

 between the feed box and the hopper, which extends under the rest 

 of the screen, a space of thirty by twenty-one inches. Except in 

 front, the Upper edges of the hopper are fastened to a wooden frame
