These trackers are particularly good at spooring camels. To anyone not accustomed to them the footmark of one camel looks very like that of any other camel, but to a trained eye they are all as different as people's faces, and these trackers remember them very much as you would remember the faces of people you had seen.

About a year ago a camel was stolen near Cairo. The police tracker was sent for and shown its spoor. He followed it for a long way until it got into some streets where it was entirely lost among other footmarks. But the other day, a year later, this police tracker suddenly came on the fresh track of this camel; he had remembered its appearance all that time. It had evidently been walking with another camel whose footmark he knew was one which belonged to a well-known camel thief. So without trying to follow the tracks when they got into the city he went with a policeman straight to the man's stable and there found the long-missing camel.

These are some of them:
