Stopping work at about five o'clock, the train of red ants melted away before one's eyes. They dropped their task very much as a gang of men do when the whistle blows. Their day at that sort of labor was therefore only about seven or eight hours, as if some of the principles of Labor Union were in vogue among these brigands. They would kidnap only so many hours a day. The slaves, however, kept at work until dusk. Perhaps the red ants continued inside the nest, disposing of the pupæ captured during the day, but they brought in none after five o'clock. Three days had elapsed from the close of this raid when, for some reason, the entire colony of red ants deserted the hill, carrying the newly captured slaves and their pupæ with them. They took up their abode under a cement walk, an unusual place for red ants, and a week of incessant labor was consumed in carrying the black ants and pupæ to the new site. This was, then, a _bona fide_ exodus of an entire community. Under the cement walk to which the colony of red ants had migrated with their slaves were numerous nests of small brown ants. These swarmed one sultry afternoon, and as they came pouring out of the cracks in the walk and clustered on the surface, the fierce red ants fell upon them with fury, slaying hundreds and leaving most of the bodies on the walk, though many were carried away. This I took to be a veritable hunting expedition. Like some other "sportsmen," they appeared to kill more than they wanted, and the little heaps of winged dead were left to be scattered by a gust of wind. On the following day a new chapter opened in the history of this remarkable colony, for I found them attacking a large negro colony some distance away. Contrary to custom, the blacks defended their nests with spirit, and at first seemed to hold their own. Not divining what was to follow, I was surprised to find the red ants carrying away no pupæ. But the next day it was made plain enough, for the red ants appeared in a compact column bearing pupæ and slaves, which but a week before they had deposited under the walk, and which they were now moving for the third time. Was this a second exodus or had the move to the walk been merely an expedient until they should find a more suitable place? Without further ado they invaded the nest, and four distinct colonies (the red ants held slaves of a previous year), one red and three black, with all larvæ and pupæ and some eggs, were thus housed together. One may imagine the feelings of the unfortunate community on finding not only an invading army of freebooters, but that some thousands of their own cousins, children and all, were come bag and baggage to live with them.
