According to the ceremonial used among the Warramunga, representatives of the two phratries take part, one as officiants, the other as preparers and assistants. Only the members of the Uluuru phratry are qualified to celebrate the rite, but the members of the Kingilli phratry must decorate the actors, make ready the place and the instruments, and play the part of an audience. In this capacity, they were charged with making a sort of mound in advance out of wet sand, upon which a design is marked with red down which represents the snake Wollunqua. The real ceremony only commenced after nightfall. Towards ten or eleven o'clock, the Uluuru and Kingilli men arrived on the ground, sat down on the mound and commenced to sing. Everyone was evidently very excited. A little later in the evening, the Uluuru brought up their wives and gave them over to the Kingilli,[704] who had intercourse with them. Then the recently initiated young men were brought in and the whole ceremony was explained to them in detail, and until three o'clock in the morning singing went on without a pause. Then followed a scene of the wildest excitement. While fires were lighted on all sides, making the whiteness of the gum-trees stand out sharply against the surrounding darkness, the Uluuru knelt down one behind another beside the mound, then rising from the ground they went around it, with a movement in unison, their two hands resting upon their thighs, then a little farther on they knelt down again, and so on. At the same time they swayed their bodies, now to the right and now to the left, while uttering at each movement a piercing cry, a veritable yell, "_Yrrsh! Yrrsh! Yrrsh!_" In the meantime the Kingilli, in a state of great excitement, clanged their boomerangs and their chief was even more agitated than his companions. When the procession of the Uluuru had twice gone around the mound, quitting the kneeling position, they sat down and commenced to sing again; at moments the singing died away, then suddenly took up again. When day commenced to dawn, all leaped to their feet; the fires that had gone out were relighted and the Uluuru, urged on by the Kingilli, attacked the mound furiously with boomerangs, lances and clubs; in a few minutes it was torn to pieces. The fires died away and profound silence reigned again.[705] A still more violent scene at which these same observers assisted was in connection with the fire ceremonies among the Warramunga.
