Bobby was still a very young lad when Abel began to teach him the signs of the wilderness and the ways of the wild things that lived in the woods. He learned to know the tracks of all the animals of the region, and even how long it had been since the animals that made the tracks had passed by. And he learned to make snares and traps, and how to handle his gun--the wonderful gun which Abel told him God had sent with him from the Far Beyond--and shoot it quickly and accurately, for the man who exists upon the wilderness must know how to do these things, and his sense of observation must be keenly trained; and he must train himself to be alert.
