And who is the grandfather of these silent people? Is it not the Great Mystery? For they know the laws of their life so well! They must have for their Maker our Maker. Then they are our brothers!" Thus spoke one of the philosophers and orators of the Red men. It is no wonder that the Indian held the animals to be his brothers. In his simple mind he regards the killing of certain of them for his sustenance to be an institution of the "Great Mystery." Therefore he kills them only as necessity and the exigencies of life demand, and not wantonly. He regards the spirit of the animal as a mystery belonging to the "Great Mystery, " and very often after taking its life he pays due homage to its spirit. In many of the Dakota legends it appeared that such and such an animal came and offered itself as a sacrifice to save the Red man from starvation.
