CHAPTER IX 



ANIMAL COMMUNITIES AND SOCIAL LIFE 



83. Man not the only social animal Man is commonly 

 called the social animal, but he is not the only one to

 were bees before there were hives. The "bee-tree" is 

 familiar to many of us. The bees, in Xature, make their 

 home in the hollow of some dead or decaying tree-trunk, 

 and carry on there all the industries which characterize 

 the busy communities in the hives. A honey-bee com- 

 munity comprises three kinds of individuals (Fig. 88) 

 namely, a fertile female or queen, numerous males or 

 drones, and many infertile females or workers. These 

 three kinds of individuals differ in external appearance 

 sufficiently to be readily recognizable. The workers are
