SS Slee 236 THE BELLA COOLA INDIANS but the Aukusiut all understand that later performances by those with the same name are only possible with the assistance of carpenters. This dance has not been carried out for so many years that the details have been forgotten. THE DANCE OF THE BIRDS The Bella Coola notice that in autumn many of the birds disappear, to be seen no more until spring.

In accordance with his double function, a dual personality is attributed to him. In fact, he is almost two beings; as Sizdiominit, ““Darkness,” he causes night to come once every twenty-four hours, whereupon as Stcitoma, he brings sleep. His kusiut protégé displays on nebusam figures with black painted masks, representing both phases of his patron. THE DANCE OF THE WHIRLWIND Whirlwinds, though of rare occurrence in British Columbia, are known to the Bella Coola who believe that they are caused by the being Sxuisiaxwanem.
