Thompson - Coyote and the Tobacco-Tree
Coyote also transformed the Tobacco-tree, that killed men. Whoever went under its shade, or plucked its leaves, died. Having made a stone pipe, he went up into the shade of the tree, and, plucking some of the leaves, put them in his pipe, and smoked them. He said, "Henceforth you will be ordinary tobacco, and people will pluck and smoke you leaves without harm.
