"There was...much the same compact...“Stay or go, according as our habits and regulations suit or displease you.” But though there were no laws such as we call laws, no race above ground is so law-observing. Obedience to the rule adopted by the community has become as much an instinct as if it were implanted by nature. (Ch IX)"
