number of hogs and do the greatest amount of work with 

 the smallest amount of labor. It is built so that it can 

 be used for farrowing purposes during the winter season 

 as well as during the summer, and when not in use for 

 this purpose it may be used as a place for feeding hogs. 

 Thus the building can be put to use the entire year. 



Sanitation. In order to provide perfect drainage, un- 

 less the soil is naturally well drained, a tile drain should 

 be laid away from the hog house about every twenty feet, 

 or from a point between each two pens. This drain 

 should run away from the building at right angles, drain-

 of disposing of the flush water that may be used on the 

 inside. After reaching the outside of the pens, which are 

 next to the house, the tile may be run in any direction 

 that is most convenient. Any other system of laying the 

 tile that will afford as good drainage will be just as satis- 

 factory. The opening of the drain should be placed be- 

 tween the two pens at the point where the doors lead to 

 the outside. If the pens are sloped a little to this point 

 and the opening to the drain covered with a perforated 

 iron plate, the pens may be flushed with water at any 

 time and the excess will easily run off. This is espe- 

 cially advantageous during the hot weather of summer, 

 for cooling the house and for the purpose of scrubbing 

 the pens. 



In order to have the building free from drafts during 

 winter it should be tightly enclosed at all points, espe- 

 cially near the floor of the pens where the pigs lie in their 

 nests. This means that the doors leading from the pens 

 on the inside of the hog house to the exterior should be 

 well fitted. For purposes of warmth such a building 

 should be constructed in accordance with the latitude in
