He is assisted by a door-keeper and a fire-tender, who builds a crescent mound of earth around the fire-pit with the horns east, and keeps the fire going all night.[78] Once having entered, one is not supposed to leave the tipi until morning save briefly, taking one of the eagle feathers lying on either side of the door, and replacing it as soon as possible. The peyote,[79] in a sack or on a woven tray, is first eaten by the peyote chief, who then administers their first buttons to novices, using two eagle-tail feathers as a spoon, with three ritual feints, after which these “fly” into their mouths. Then after smoking[80] the peyote is passed around by the assistants as the leader prays. Beginning at the southeast the drum is passed clockwise as each person sings four songs, his own ceremonial songs or songs received in visions, while the leader or his assistants shakes the rattle. The leader sings most of the songs. There was a mild bias against women[81] among the Mescalero; they received medicine power, but could not become a peyote chief, because the responsibilities of the office were too great—for a leader must prevent anything happening between even the greatest of rival shamans in meetings.[82] In this he was aided by the chief peyote which “he frequently consulted ... to ascertain whether anything were amiss; any evil thoughts or efforts at witchcraft were said to ‘show’ on this ‘chief peyote’.” A favorite device of witches to weaken the leader was to make his assistants vomit the peyote. Peyotism was readily accepted by the Mescalero, in whose older culture were patterns of receiving supernatural power from animals, etc. Indeed, Opler calls the Mescalero a tribe of shamans, active or potentially active [and peyote became another among many sources of power for them]. It will be readily grasped, however, that since peyote leadership and the conduct of peyote rites were open to any one who claimed a supernatural experience with the plant, since, in other words, an individualistic, shamanistic premise underlay the utilization of peyote for religious purposes, centralized leadership and definite organization could not be achieved. The Mescalero use of peyote never developed into a cult or society with a regular membership and place of meeting, with officers and principals selected or agreeable to the entire body of devotees ...
