WINTER CEREMONIAL DANCES 147 a mask representing a man and carries a stick with which he beats on the floor as he cries out: “Come, ye supernatural ones. The most famous kusiut of all [Thunder] is about to dance.” Thunder. The mask representing this creature is large and of fearsome appearance with hooked beak and overhanging forehead; it is always carried by a man of powerful physique (see Plate 9). A box has been placed beside the enclosure so that, when Thunder first appears, standing upon it, his ap- parent size is increased. He bends to and fro, and up and down, in an amazing fashion, blowing through his clenched teeth, while 4no°likwoisaix informs the uninitiated who he is, and expatiates on his powers. After twisting and turning for several minutes, Thunder leaps to the floor of the house, and as he does so there sounds a peal of thunder. The uninitiated do not know that this is caused by a number of kukusiut rolling stones to and fro in large wooden boxes within the enclosures at the back. Then he starts to dance sunwise around the fire, bending down and up, shaking himself and stamping violently, his amazing gyrations being constantly accompanied by the reverberation of rolling stones. Escorted by several kukusiut he circles the fire, and after a final stamping and twisting, dis- appears into the enclosure. In a few minutes he appears again, and repeats his dance. Since no one man is strong enough to carry out this athletic performance twice in succes- sion, the mask has been transferred to another Rusiut within the enclosure, but of course the uninitiated are unaware of this. Thunder always comes out four times in all, on each occasion dancing once around the fire. Sometimes four dif- ferent men perform; sometimes the one who danced first has recovered sufficiently to be able to repeat on the fourth round. The usual explanations by 4noVikwoisaix add zest to the rite. On this occasion the customary dance of Thunder with a fire tattle was omitted. SxnxnesGxs.
