The big , serious , old brown bear was delighted to have so quick a pupil , for the young wolves will only learn as much of the Law of the Jungle as applies to their own pack and tribe , and run away as soon as they can repeat the Hunting Verse -- `` Feet that make no noise ; eyes that can see in the dark ; ears that can hear the winds in their lairs , and sharp white teeth , all these things are the marks of our brothers except Tabaqui the Jackal and the Hyaena whom we hate .
