The order was a secret one, and in some respects not unlike the Free Masons, being a union or affiliation of a number of lodges, each with its distinctive songs and medicines. Leadership was in order of seniority in degrees, which could only be obtained by merit, and women were admitted to membership upon equal terms, with the possibility of attaining to the highest honors. No person might become a member unless his moral standing was excellent, all candidates remained on probation for one or two years, and murderers and adulterers were expelled. The commandments promulgated by this order were essentially the same as the Mosaic Ten, so that it exerted a distinct moral influence, in addition to its ostensible object, which was instruction in the secrets of legitimate medicine. In this society the uses of all curative roots and herbs known to us were taught exhaustively and practiced mainly by the old, the younger members being in training to fill the places of those who passed away. My grandmother was a well-known and successful practitioner, and both my mother and father were members, but did not practice. A medicine or “mystery feast” was not a public affair, as members only were eligible, and upon these occasions all the “medicine bags” and totems of the various lodges were displayed and their peculiar “medicine songs” were sung. The food was only partaken of by invited guests, and not by the hosts, or lodge making the feast. The “Grand Medicine Dance” was given on the occasion of initiating those candidates who had finished their probation, a sufficient number of whom were designated to take the places of those who had died since the last meeting. Invitations were sent out in the form of small bundles of tobacco. Two very large teepees were pitched facing one another, a hundred feet apart, half open, and connected by a roofless hall or colonnade of fresh-cut boughs. One of these lodges was for the society giving the dance and the novices, the other was occupied by the “soldiers,” whose duty it was to distribute the refreshments, and to keep order among the spectators. They were selected from among the best and bravest warriors of the tribe. The preparations being complete, and the members of each lodge garbed and painted according to their rituals, they entered the hall separately, in single file, led by their oldest man or “Great Chief.” Standing before the “Soldiers’ Lodge,” facing the setting sun, their chief addressed the “Great Mystery” directly in a few words, after which all extending the right arm horizontally from the shoulder with open palm, sang a short invocation in unison, ending with a deep: “E-ho-ho-ho!” This performance, which was really impressive, was repeated in front of the headquarters lodge, facing the rising sun, after which each lodge took its assigned place, and the songs and dances followed in regular order.
