        UNREWARDING MOUTHFULS
        Jaws and teeth are rarely eaten by a
        predator, since the teeth are too
        hard and their roots project into
        the jawbone.

               Barbed wire is the artificial equivalent of the thicket, and just as good at snagging fur from passing animals.
               The height at which the fur was caught, and the size of the hole through which the animal pushed, are
               important clues, as well as the color and nature of the hairs.
