Every year the red ants raid the common blacks for the purpose of making slaves--a most highhanded proceeding. This season I came upon the invading host marching up the road about ten in the morning of July 28th. The invasion had but lately begun, as the ants were carrying no pupæ; it was the skirmish line. As the column advanced, frequent and rapid communication took place between individuals and stragglers who were coming back. Later, when the raid was well under way, there was little of this. The nest of the red ants was by the side of a path in the woods which led out to the wagon road, while the negroes were domiciled some distance up this lane. Now the column of red ants followed the path and the road the entire way, in place of going directly through the bushes, though it doubled the distance, which thus amounted to some fifty yards. Red ants were soon pouring out of the various openings in the nest of the blacks, carrying both pupæ and larvæ, and rarely one passed with a bunch of small white eggs. Several black queens came out of the nest, and as they emerged were set upon by red ants, which tried to hold them by their wings. They managed, however, to throw off their assailants, and ran under my feet, where they were followed by a score of black workers, all of whom crowded under the soles of my shoes as I stood on the loose gravel. At noon I timed the ants and found that, on the average, forty pupæ and larvæ were carried past a given point every minute. Two unbroken columns now extended the entire distance between the nests, one advancing and the other returning. Occasionally one passed carrying a portion of a black ant, a head and thorax, or an abdomen. Again, one would appear with a live black, which, when liberated by me, frantically made her escape. Very young negroes when carried off were never injured. On one occasion several red ants were struggling with a black, and among them was a black who fought against her own friend. This is the only case in which I saw a black ant help the enemy in this way--a traitor, evidently, but presumably one whose pupa had been captured the year before and reared in slavery. Whereas the red ants always came to each other's assistance, the blacks rarely did so. By five o'clock the raid was practically over for the day. It ceased as suddenly as it had begun. Early in the struggle a slender, straggling column had diverged from the main line, about half way between the nests. I now found the entire body of ants moving in this new direction. The one raid over, they had undertaken another upon a colony of blacks some twenty-five yards distant, and were transporting the pupæ and larvæ at about the same rate as before. To reach this nest, the column must cross the wagon road, and here a number were crushed from time to time by passing vehicles. But the marching army passed by with the stolen pupæ and paid no heed to their wounded comrades. This second foray ceased before nightfall.
