ECONOMIC VALUES OF ANIMALS 537 



ducing animals were owned in the United States. The United 

 States, Argentina, and Australia are the greatest producers of 

 cattle. Other products, such as milk, butter, and cheese, are ob- 

 tained from cows and goats. In this country many hogs are raised 

 for food. Their meat is used fresh, salted, smoked as ham and 

 bacon, and pickled. Sheep, which are raised in great quantities 

 in Australia, Argentina, Russia, Uruguay, and this country, are 

 one of the world's greatest meat supplies. Deer, many game 

 animals, seals, walruses, etc., are available as food for people in 

 certain parts of the earth. 



Practical Exercise 19. From the information obtained from your local 

 Chamber of Commerce or other sources, make a report to the class on the 

 value of food mammals in your community.

PROBLEM IV. WHAT ARE OTHER ECONOMIC VALUES OF 



ANIMALS? 



Domesticated animals. The domestication of the dog, the cow, 

 the sheep, and especially of the horse, marks epochs in the advance 

 of civilization. Beasts of burden are used the world over : horses 

 almost everywhere ; certain cattle, as the water buffalo, in tropical 

 Malaysia ; and camels, goats, and the llamas in some other coun- 

 tries. 



Practical Exercise 20. Obtain from local sources the approximate value of 

 domesticated animals in your locality, and tell why you think your figures 

 are accurate.
