passage it is tightly boarded, but over the pens on each side of 

 the passage the ceiling consists of 8-inch planks laid 2 inches 

 apart, over which is kept a layer of straw at least 12 inches thick. 



Fresh air is admitted through the windows, which are hinged 

 at the bottom and open inwards at the top. On each side of the 

 window frame there is fitted a triangular piece of board with 

 its edge against the wall and with the base of the triangle upward. 

 When the window is open, these flanges prevent the air from 

 escaping into the piggery except at the top, thus forcing the 

 air to take an upward direction as it enters the building. The 

 spaces between the planks of the ceiling are depended upon to 

 permit the escape of foul air and moisture from the building. 



Pens. The larger pens are 11 x 12 feet, with beds 6x8 feet. 

 The smaller pens are 8x12 feet, with beds 5 ft. 6 in. x C ft. 



Around the beds is a cement curb rising 6 inches above the 

 level of the floor, and the space inside the curb is covered 

 with plank. 



The feed room is 12 x 16 feet, and the partitions run to the 

 ceiling. Across the passage from the feed room are two pens 

 8 x 12 feet, and between these pens and the rest of the building 

 are partitions which run to the ceiling. In the passage are 

 double doors which may be closed, thus shutting off the two 

 small pens entirely from the rest of the building. These two 

 pens are intended for farrowing pens, especially in cold weather. 

 If the weather is very severe, a fire can be built in the feed room, 

 and by leaving the feed room door open into the passage, the 

 temperature of the two pens can be considerably modified. 

 The remaining small pens are intended for sows with their 

 litters, and the young pigs with their mothers may be re- 

 moved from the farrowing pens into the other part of the 

 building as soon as the pigs are strong enough to stand the 

 lower temperature.
