181:"Termites, those energetic destroyers of wooden foundations, are the main concern of Professor S. F. Light of the Department of Zoology. Within the wooden portions of many California homes live hierarchies of termites with their queens, soldiers and workers, producing young which swarm to new fields with the first rain. Shown at the left is the forward portion of the soldier termite whose duty it is to protect the colony when by misadventure a portion of one of the tunnels is broken open. The soldier termite carries all the equipage of war; he is heavily armored in front, has a large pincers, and is able to exude a noxious gas at this natural enemy, the ant. Below, Dr. Light is examining experimental groups of termites, of which he has several hundred under way, and which are destined to analyze the mechanism which controls the development of the termite society or colony. Some scientists attribute the "caste" differences to different types of eggs; others to differences in feeding, as in the case of bees." (Sibley, p. 196)
