During our first night among my new friends we had a most unpleasant experience, in the shape of a visitation from an army of brown ants, which came right through the camp. These brutes—they are about half an inch long, and so may be rightly called brutes—have very powerful jaws, like the claws of a lobster, and bite most fearfully. They covered everything in their path, and, getting into the blankets, drove me out of my tent, and caused every one to dance about in the most comical fashion in their efforts to get rid of the pests. So tenacious were they that one could hardly pull them off, and the whole camp was in an uproar during the hours that the army took to pass, and there was little more sleep that night for any one. I do not know to what particular variety of the ant tribe these brutes belonged, but I should think that they must bear a strong resemblance to the kind known as “the bull-dog ant,” which is, among certain African tribes, looked upon as a valuable assistant to the native surgeon, who uses it instead of the silk thread and surgical needle of civilization for sewing up wounds. The manner in which they are used for this purpose is as follows: The edges of the wound are drawn together, and held in that position with the fingers of the left hand, while with the right a bull-dog ant is picked up and held so that the jaws grip one on each side of the wound; the body of the ant is then twisted off, while the head still remains, tenaciously holding on to the flesh. From this habit of holding on they have acquired the name of bull-dog. The Kikuyu did not make any such use of these ants, though their method of sewing up wounds was scarcely less primitive. In their case the edges of the wound were drawn together and a long thorn run through both. A fine thread, made of fibre from the bark of certain trees, is then wound over both ends of the thorn, in the same way that sailors wind the spare ends of ropes round the cleats. The thorn is left in place till the wound heals, and then drawn out in the same way that a surgeon removes the stitches after more civilized operations. Next morning we struck camp and resumed our journey, the chief accompanying me to the boundary of his territory. On the way he told me that he had had a lot of trouble with the neighbouring tribes, particularly the people I was going to visit, the Kalyera, with whom he was in a state of continual warfare. He parted from me with a serious warning to be very careful, as the people I should next meet were very treacherous.
