tition shelters from draughts and also economizes bedding by 

 holding the straw in place. The other partitions are four feet 

 high. The partition next to the feeding passage is made of 

 woven wire fencing of No. 9 coil steel wires, two inches apart 

 at the bottom, and grading to about three inches apart near the 

 top. The wire partition is set in about two and a half inches 

 from the side of the trough next to the feed passage, thus 

 allowing room to pour feed into the troughs. 



The troughs are cement, and are eight inches high next to 

 the feed passage, four inches high next to the feeding pen, and 

 ten inches wide, inside measurement. 



The feed passage, which is five feet wide, is four inches 

 lower than the feeding pen. This is merely a device to show 

 the pigs to better advantage. 



Doors. The purpose of the doors in the partitions between 

 the pens is easily understood. They can be swung back, closing 

 the pigs in the back apartment and leaving a continuous pas- 

 sage for cleaning out the pens. The bedding is also taken in 

 and distributed from this passage. These doors are also used 

 in moving pigs from one pen to another, since there are no 

 doors from the pens into the feed passage. The absence of 

 doors from the pens into the feed passage is a somewhat in- 

 convenient feature of the building, but is hard to avoid where 

 a woven wire partition is used. The woven wire partition, 

 however, is more sanitary than wood, and gives a much better 

 view of the pigs. 



Floors. It will be noticed that the sleeping quarters have 

 cement floors. When bedding is plentiful this may give no 

 trouble, but it would be safer to place a portable wooden plat- 

 form on the cement. 



The floor may be kept warm and free from the ascending soil 

 moisture by placing a layer of tar paper or tar paint between the
