Once in camp I put a log on top of the fire and it was full of ants. As it commenced to burn, the ants swarmed out and went first towards the centre where the fire was, then turned back and ran towards the end. When there were enough on the end they fell off into the fire. Some got out, their bodies burnt and flattened, and went off not knowing where they were going. But most of them went toward the fire and then back toward the end and swarmed on the cool end and finally fell off into the fire. I remember thinking at the time that it was the end of the world and a splendid chance to be a messiah and lift the log off the fire and throw it out where the ants could get off onto the ground. But I did not do anything but throw a tin cup of water on the log, so that I would have the cup empty to put whisky in before I added water to it. I think the cup of water on the burning log only steamed the ants.
