The Traditions of the Hopi, by H.R. Voth, , at sacred-texts.com
Long ago Yáyaponchatu live near Oraíbi. They are like skeletons, white with disheveled hair, and wear kilts of black and white striped cloth. They understand fire. Oraíbi barter by putting things on pile in kiva and sending round to different kivas to trade things off. Yáyaponchatu send two to trade for native tobacco. They go to kiva and let down bundles of broom grass. They make Hopi understand what they want, and one of them gets tobacco. They go to another kiva, and other one trades broom grass for tobacco. They are happy. and in village smoke tobacco.
