544 GENERAL BIOLOGY —A REVIEW AND SUMMARY 
414. Relation of Animals and Plants to Man. —No summary 
of a general course in biology would be complete that did 
not indicate some of the general relations of living organisms 
to man. They are our indispensable friends or unceasing 
enemies. The story of how man has come to control the 
multitudes of living things is as full of interest as it is im¬ 
portant to the continuance of a progressive civilization. 
There still remains much for man to discover, but we should 
be intelligent about what has already been accomplished. 
Man makes a greater use of the plant world than any 
other animal, and he uses the animal world for his benefit 
far more than any other animal. Because man is the highest 
type of animal he has gained mastery over plants and 
animals. Those nations that have found out the best ways 
to utilize the greatest number of plant and. animal products 
are the dominating powers of the world. Closely associated 
with man’s utilization of the organic world is his greatly 
improved use of natural forces and of the inorganic world.

415. Community Life. — It has often been said that man 
is a social animal. Man is not the only social animal. The 
communal life of the honey-bee, ants, and termites shows 
many wonderful examples of labor for the benefit of a whole 
colony. The honey-bee, when first out of the cocoon, as 
an adult is a nurse for the larvae, later a wax-maker for the 
colony, and later a field worker, a gatherer and maker of 
honey. Most of the work of the midsummer honey-bees is 
for others, since they die before winter begins. Conse¬ 
quently these bees are community builders in a real sense 
of the word. Ihose insects that have the greatest number 
of workers and the most extensive division of labor are the 
most successful in the struggle for existence. When we
