ANIMALS, 



THE two forms of life upon the earth are plants and 

 animals. The chief purpose of vegetable life is to

 supply of food for animals. 



A knowledge of these crops is not completed until we 

 have considered them as fed to animals to produce meat, 

 milk, wool, work, etc. 



It is very important to understand the nature, the 

 peculiarities, the best methods of feeding, and the proper

 the flesh of other animals, and are called cafnivorous, 

 or flesh-eating animals. Some live partly upon plants
