“In those days we had never heard of passing up a chance to kill a wolf…. I was young then…. I thought because fewer wolves meant more deer, that no wolves would mean hunter’s paradise…. Since then I have lived to see state after state extirpate its wolves…. I have seen every edible bush and seedling browsed, first to anemic desuetude, and then to death…. I now suspect that just as a deer herd lives I mortal fear of its wolves, so does a mountain live in mortal fear of its deer…. Perhaps this is the hidden meaning in the howl of the wolf, long known among mountains, but seldom perceived among men.”
