THE ECONOMIC IMPORTANCE OF ANIMALS i>o;i 



Goats, deer, many larger game animals, seals, walruses, etc.,

Uses for Clothing. - The manufacture of silk is due to the pro-

 It lives upon the mulberry and makes a cocoon from which the silk 

 is wound. The Chinese silkworm is now raised to a slight extent 

 in southern California. China, Japan, Italy, and France, because 

 of cheaper labor, are the most successful silk-raising countries. 



The use of wool gives rise to many great industries. After the 

 wool is cut from the sheep, it has to be washed and scoured to
