The thunder is believed to bring the rain in spring, and the rain makes the berries grow. It is a rule that after the first thunder is heard in the spring, every medicine man must give a feast and offer prayers for a large berry crop. I have never seen this ceremony, but Mr. Schultz was once permitted to attend one, and has given me the following account of it. He said: "When I entered the lodge with the other guests, the pipe stem had already been unrolled. Before the fire were two huge kettles of cooked sarvis berries, a large bowlful of which was soon set before each guest. Each one, before eating, took a few of the berries and rubbed them into the ground, saying, 'Take pity on us, all Above People, and give us good.'
"When all had finished eating, a large black stone pipe bowl was filled and fitted to the medicine stem, and the medicine man held it aloft and said: 'Listen, Sun! Listen, Thunder! Listen, Old Man! All Above Animals, all Above People, listen. Pity us! You will smoke. We fill the sacred pipe. Let us not starve. Give us rain during this summer. Make the berries large and sweet. Cover the bushes with them. Look down on us all and pity us. Look at the women and the little children; look at us all. Let us reach old age. Let our lives be complete. Let us destroy our enemies. Help the young men in battle. Man, woman, child, we all pray to you; pity us and give us good. Let us survive.'
"He then danced the pipe dance, to be described further on. At this time, another storm had come up, and the thunder crashed directly over our heads.
"'Listen,' said the medicine man. 'It hears us. We are not doing this uselessly'; and he raised his face, animated with enthusiasm, toward the sky, his whole body trembling with excitement; and, holding the pipe aloft, repeated his prayer. All the rest of the people were excited, and repeatedly clasped their arms over their breasts, saying: 'Pity us; good give us; good give us. Let us survive.'
"After this, the pipe was handed to a man on the right of the semi-circle. Another warrior took a lighted brand from the fire, and counted four _coups_, at the end of each _coup_ touching the pipe bowl with the brand. When he had counted the fourth _coup_, the pipe was lighted. It was then smoked in turn around the circle, each one, as he received it, repeating a short prayer before he put the stem to his lips. When it was smoked out, a hole was dug in the ground, the ashes were knocked into it and carefully covered over, and the thunder ceremony was ended."
