Thus, so far as this one colony is concerned, the food was gathered almost entirely by workers of these two intermediate sizes; the one, no. 3, so far as I have observed, without exception, first gathering the fluid from the aphids, and no. 2 principally transporting it to the nest, though aided by some of no. 3. I have not observed other colonies sufficiently to determine whether this practice is general among them, though it surely cannot be universal for many colonies find their aphids on the same tree in which they live. This was a mature colony of large size and had probably perfected this division of labor gradually as the colony developed in conformity to the conditions that surrounded them. The work of the two extreme sizes is more difficult to make out, for they are in some way the "house-keepers," that is, they are, during the daytime, at least, about the nest. The smaller ones, size no. 4, are often seen carrying the particles of wood and the empty pupa cases from the nest. Taking into account the immense mandibles of size no. 1, one might suppose that these are the true carpenter ants, and that it is their business to build additions to the formicary; but as has been shown in the tables above, they appear in the colony after it is pretty well established, and then occur in rather small numbers we must at least conclude that they are not the only carpenters in the colony. In general behavior they resemble very much the virgin queens. In the artificial nest they remain constantly in the dark room, and when the colored glass is removed they are among the first to seek shelter and the last to show fight.
