abdomen, the rotund—throws her head up, and a drop of clear, amber fluid is then seen to exude from her mouth, which is eagerly licked up by the workers. It is to be presumed that the latter crawl up the walls of the honey-chambers in order to be fed by the rotunds; but I am not quite sure whether Mr. MacCook, who kept these ants, and is the authority upon them, ever actually saw them do this. On the other hand, he often saw them fed upon the ground; but then, I think, he had put the honey-bearing ants there. In his book he gives some interesting illustrations of the feeding taking place. It used to be thought that these poor honey-pot ants were unable to walk, and lived all their lives in one place. This, however, is not the case. Mr. MacCook tells us that he has “frequently seen them coming out of their chambers, ascending the galleries, and moving freely about them.” They went sideways, and half slid and half crawled along. Again, when he placed them on a table, they were able to move “with no little agility.” If, however, they happened to fall from the roof where they were clinging, which sometimes they did through people shaking them, they were not able to get up again, but lay there helpless. It is not always, however, that these honey-jars are full, and when they are half or three-quarters empty they can walk very much better. Some ants, it is now well known, are accustomed to store up grain in their nests during the summer or autumn, so as to have a supply of food during the winter. Long ago this habit had been recorded by Solomon, who says, “The ants are a people not strong, yet they prepare their meat in the summer”; and again, “Go to the ant, thou sluggard; consider her ways, and be wise: which having no guide, overseer, or ruler, provideth her meat in the summer, and gathereth her food in the harvest.” Classic writers have also dwelt upon this interesting point in ant economy, so that for a long time it was taken for granted not only that some ants stored grain, but that all of them did. However, when the European species began to be observed very carefully, this opinion was found to be erroneous, and Huber and other investigators, having convinced themselves that grain in these instances was not so stored, opinion began to go to the other extreme, and the fact was denied altogether. It was supposed that Solomon, and the ancient writers generally, had seen the ants carrying their little white larvæ or pupæ—as anyone may do who disturbs a nest—and that these had been mistaken for seeds.
