In Indian social organization, a problem at once suggests itself. In these communities, comparatively populous, how could spirits so fierce, and in many respects so ungoverned, live together in peace, without law and without enforced authority? Yet there were towns where savages lived together in thousands with a harmony which civilization might envy. This was in good measure due to peculiarities of Indian character and habits. This intractable race were, in certain external respects, the most pliant and complaisant of mankind.
