Benjamin Louis Eulalie de Bonneville, The Adventures of Captain Bonneville…
“ In war, every one is on the alert. If we see a trail we know it must be an enemy; if the Blackfeet come to us, we know it is for war, and we are ready. Peace, on the other hand, sounds no alarm; the eyes of the chiefs are closed in sleep, and the young men are sleek and lazy. The horses stray into the mountains; the women and their little babes go about alone. But the heart of a Blackfoot is a lie, and his tongue is a trap. If he says peace it is to deceive; he comes to us as a brother; he smokes his pipe with us; but when he sees us weak, and off our guard, he will slay and steal. ”
