Ant invasion: Sometimes I would spend an odd quarter of an hour studying the psychological equipment of these queer little creatures. Once I found a long line of black ants on the march from the foot of a tree to my hut. They moved in perfect order. The vanguard had already reached their objective and were even now attacking my store of sugar fiercely, despite the fact that it was kept in a tin reputed to be airtight. Saddening experience, however, had already taught me that airtight was not at all the equivalent of "ant-tight." I hastily diverted the foremost members of the army corps into other directions; but with a curious obstinacy the retiring ranks refused to flee and continued the attack with unabated ardour. I kept on pushing away the new arrivals, but to no purpose. Hundreds more arrived to take their place.
