416 SHEEP AND SWINE 



One thing more must not be forgotten. Dogs are the 

 natural enemy of sheep. During 1915 according to the 

 statistical bureau of the State Department of Agriculture 

 of Pennsylvania 5808 sheep were killed by dogs in Penn- 

 sylvania alone and 3813 were injured. And Pennsylvania 

 is not a leading sheep state. The bark or often even the 

 presence of a dog may create a stampede. This excites 

 and worries the sheep, even though the dog does no 

 injury directly. Thus chased they soon become exhausted 

 and rapidly lose weight. The collie, however, has been 

 bred to be the friend and companion of sheep. Read the 

 charming story of " Wully " in Wild Animals I Have 

 Known, and you will readily understand why sheep will

 the mire. In justice to the pig, it can be said with truth 

 that he must abide by the conditions imposed on him by 

 his master. He prefers a clean, dry bed, and he shows 

 this fact if he has a fair chance to do so. But there is 

 little evaporation from his body to cool his skin, and he 

 has only a scant supply of hair for protection against flies. 

 So, if no bath is at hand, he naturally wallows in the mud 

 as the best means of keeping comfortable during hot 

 weather. 



307. Types of Swine. There are two types of swine, 

 the lard type and the bacon type. These types have been
