4 DOMESTICATED ANIMALS AND PLANTS 
provides an ample and assured food supply in its domesticated 
animals and cultivated crops. 
To be sure, a certain amount of meat still comes from game 
like the deer and the moose, but the proportion is small and is 
growing smaller every year. The pioneer, like the Indians, de- 
pended largely on the hunt, but the buffalo is extinct and the 
game animals generally are restricted to the protected preserves 
where they linger only by virtue of stringent laws. 
Fish have been strictly undomesticated in the past, but now 
all the promising rivers and lakes are systematically ‘‘ stocked,” 
so that even these lowest of all food animals are almost half 
domesticated, in that they are systematically cared for. Any 
way we study the problem we always arrive at the same conclu- 
sion, namely, that we are absolutely dependent for food upon 
the products of plant and animal life. 
Animals and plants as sources of clothing. Primitive man 
clothes himself in skins, like the Eskimo, if he needs their 
warmth, or in grasses, like the Fiji islander, if he does not. 
Civilized man,, however, refining upon savage customs, weaves 
a cloth out of the fiber of the pelt or of the leaf, and cuts him- 
self garments that fit the body and lend themselves to its move- 
ments. In this way the wool of the sheep and the fiber of the 
cotton and the flax furnish the material out of which the world 
clothes itself. 
Aside from furs, and many of these come from lambs and 
from cats, we draw our clothing supply from animals and plants 
living under the direct management and control of man, that 
is, domesticated. The wool of the sheep, the fur of the vicufia, 
and the hair of the llama and the alpaca are all body coverings 
shorn for spinning. The fiber of cotton and of flax represent 
two of our principal crops the world over, and the silk that is 
spun by the insignificant worm represents an industry involving 
thousands of people, millions of worms, and acres of mulberry 
trees. In clothing, therefore, as in food, our supply is mainly 
drawn from domesticated races.
