They assemble in a lodge, wearing tall, conical hats, being nearly naked, and painted in a strange style. Upon the fire is placed a huge kettle full of meat, and they remain seated around the fire smoking until the water in the kettle begins to boil, which is the signal for the dance to begin. They dance and sing around it excitedly, plunging their hands into the boiling water, and seizing large pieces of hot meat, which they devour at once. The scalding water is thrown over their backs and legs, at which they never wince, complaining that it is cold. Their skin is first deadened, as I am creditably informed, by rubbing with a certain grass; and they do not in reality experience any uneasiness from the boiling water--a fact which gives their performances great mystery in the eyes of the uninitiated. § 221. Dr. Brinton has confounded the Heyoka with the Wakinyan. The two are distinct classes of powers, though there is some connection between them, as may be inferred from the following stories in the Bushotter collection. § 222. No Indian belonging to the Heyoka Society ever tells of his own personal mystery. Such things are “wakaŋ,” and not even one man can be induced to sing the Heyoka songs upon an ordinary occasion; because if they sing one of those songs except at the proper time they say that the Thunder-beings would kill the entire households of the offenders. Therefore they object to singing the Heyoka songs and they do not like to speak about them. STORY OF A HEYOKA MAN. § 223. It is said that the people of the olden times knew when they were about to die, and they used to dream about their deaths and how they would be when the time drew near. One of those men said, “When the first thunder is heard next spring, I and my horse shall die.” For that reason his kindred were weeping from time to time, this man who had dreamed of his death decorated the legs of his horse by moistening light gray clay and drawing zigzag lines down the legs. In like manner he decorated the neck and back of the horse, and he made similar lines on his own arms. Then he would walk about the prairie near the camp, singing and holding a pipe with the stem pointing toward the sky.
