In some inland post feel the savagery, the utter savagery, had closed round him--all that mysterious life of the wilderness that stirs in the forest, in the jungles, in the hearts of wild men. There's no initiation either into such mysteries. He has to live in the midst of the incomprehensible, which is detestable. And it has a fascination, too, which goes to work upon him. The fascination of the abomination--you know. Imagine the growing regrets, the longing to escape, the powerless disgust, the surrender, the hate.
