tion need not be more than three feet six inches above the floor. With the 

 possible exception of the boar, a hog that requires higher fencing than this is 

 an undesirable one to have. 



The yards on the north side of the building where the boars are kept during 

 a part of the season, are separated by board fences, this being the only safe 

 material for the divisions between them; the ends of these pens are, however, 

 enclosed with woven wire. On the south side the pens are constructed of woven 

 wire, the method of construction being fully described later in this publication. 

 On the north side of the building, the slope of the ground was such that the 

 desired fall could not be given the yards but on the south side a fall of a little 

 more than a foot was established in the twenty-two feet of length, giving most 

 excellent results. The possibilities for securing a good fall in every direction 

 from the piggery should be one of the most important factors in determining its 

 location. Wallows in pig yards, containing the drainiugs from the manure pile, 

 putrid water and other filth, are prolific breeders and distributors of disease. On 

 both sides of the building strips of cencrete three feet wide, were laid next to 

 the walls. This has served an excellent purpose in preventing the hogs from 

 rooting holes and forming wallows against the foundations, thus injuring them.
