The Traditions of the Hopi, by H.R. Voth, , at sacred-texts.com
Big Head and Goat Horn are friends, but live so far apart in Oraíbi they do Hot often visit each other. Once Goat Horn visits friend and, after eating, he goes home, telling friend he must visit him sometime. Big Head goes and stays night with friend. In morning he kills goat, cuts it in two, and gives friend half. Big Head takes it with him, and that is reason why Hopi when they kill goat cut it up.
