“ Then the Raven chief took from the long parfleche sack a slender stick, beautifully dressed with many colored feathers; and on the end of it was fastened the skin of a raven, head, wings, feet, and all. "We," he said, "are the Mas-to-pah'-ta-kiks (Raven carriers, or those who bear the Raven) . Of all the above animals, of all the flyers, where is one so smart? None. The Raven's eyes are sharp. His wings are strong. He is a great hunter and never hungry. Far, far off on the prairie he sees his food, and deep hidden in the pines it does not escape his eye. Now the song and the dance." ”
