 clothing. The furs of wild animals and the leather and 

 the wool of domestic animals are most important in 

 protecting the body of man from unfavorable weather. 

 Among the domestic 

 animals the horse is 

 useful for driving and 

 draught work, and the 

 cow for its flesh, milk, 

 and butter. The sheep, 

 through its flesh and 

 wool, is an economic 

 factor of great impor- 

 tance in civilization. 

 There are harmful 

 mammals like gophers 

 (go'ferz), prairie dogs, 

 rabbits, rats, and mice. 

 Lions and tigers some- 

 times kill human be- 

 ings. Weasels, skunks, 

 and mink are often 

 harmful in poultry 

 yards.
