These are workers, and blind ; they never voluntarily come out of their gal- leries, all their wander- ing being in tunnels of enormous length run over or under ground in every direction from the main nest. If they must reach a point to which they cannot burrow, they build a covered way of earth mixed with saliva, woody and excrementitious matter. These workers are the most familiar to the casual observer, and form much the greater pro- portion of the inhabitants of a nest or colony. They have distinct, hard, brown mandibles, not excessive in size, and can be thus readily distinguished from the soldiers, which are larger, with proportionately larger heads and very largely developed mandi- bles. The soldiers form a standing army whose duty it is to protect the community ; therefore, if we disturb a colony the workers at once run away, leaving the field to the soldiers, wli are impotent enough in the daylight, blindly gnashing their jaw but are no doubt useful in the ordinary routine of Termite lif Early in spring we find, in addition, larger, winged individual . chestnut-brown in color, and these are the true sexed forms, male and female.
