1906.] BEEP CATTLE EXPERIMENTAL PLANT. 307 



SHED 



The shed south of the alley is 250 feet long and 12 feet wide 

 and is divided into seven equal compartments by the extension of 

 the same fences which separate the corresponding feed lots. 



The sides and roof of this shed are supported on the north side 

 by split oak posts set in the ground 6 feet apart and on the south 

 side by 4x4/5 set 12 feet apart. The plates are 2x6's; rafters, 

 2x6's, 3 feet on center. The shed is sided with- 8 inch ship-lap. 

 The north side of the shed, which faces the paved alley, is 6 feet 

 high while the south side is 8 feet high thus giving the roof a slope 

 of 2 feet. The boards of the roof project over the frame work 

 i foot 5 inches on the side toward the lots and 7 inches on the side 

 toward the alley. The sheds are covered with I inch lumber over 

 which is fastened prepared roofing. Plates i, 2, and n. 



FEED BUNKS, TRACK, HAY MANGERS, AND WATER SUPPLY 



The feed bunks are 5 feet 9 inches by 18 feet and are located 

 5 feet 6 inches from the shed. The posts are 4x4' s, 9 feet apart 

 one way and 6 feet apart the other way. All extend from the pave- 

 ment above the bunk to form the framework of the feed carrier's 

 track. On top of the 4x4 uprights are nailed 4x4 cross pieces. 

 Short 2x4*5 are placed as stays between the 4x4*5 on the side of the 

 bunk. The floor is made of 2x6's, resting on 2x6 pieces, spiked 

 to the posts i foot above the pavement. The sides and ends are 

 2x6's. ix6-inch fence boards are nailed lengthwise of the bunk for 

 strengthening purposes. Plates i, 9, 10, and n. 



Two hay mangers in each lot are built of material of the 

 same size and in the same manner. The posts are 4x4's resting 

 upon the brick pavement and are placed 4 feet 6 inches apart. The 

 flooring is made of ix6's (matched) and rests upon 2x4 ties nailed 

 to the posts. The sides and ends of the manger consist of a 2x 12- 

 inch and a 2x6-inch piece. ix6-inch cross pieces, placed 3 feet 

 above the floor of the manger, help to strengthen the structure.

The entire length of the track is 270 feet and the total fall, 1 1.25 

 feet, which means a fall of i foot in 24 feet. However, the fall 

 from the door of the barn to the west side of lot 4, a little over half 

 the distance, is I foot in 19.8 feet, while the remaining fall is only I 

 foot in 36.5 feet. Thus it is seen the greatest fall is allowed just 

 after the carriers leave the door. This is done for two reasons. 

 First, the track could not be any lower in lot 7 (the last of the 

 series) without having the feed carrier so low at that place as to
