At first Jack fancied that his chum was maintaining this rigid attitude, so that the bull might not notice him. It is a favorite scheme of a still hunter approaching a feeding deer, to keep his eye on the animal's tail. When he sees the tail give a twitch he stands perfectly still, knowing the deer is going to raise its head to look around for signs of danger, and that if he does not move a muscle, it will more than likely take him for a stump.
