Still more stringent are the precautions taken when the fish are the first of the season. On salmon rivers, when the fish begin to run up the stream in spring, they are received with much deference by tribes who, like the Indians of the Pacific Coast of North America, subsist largely upon a fish diet. In British Columbia the Indians used to go out to meet the first fish as they came up the river. “They paid court to them, and would address them thus. ‘You fish, you fish; you are all chiefs, you are; you are all chiefs.’ ”(381) Amongst the Thlinket of Alaska the first halibut of the season is carefully handled, addressed as a chief, and a festival is given in his honour, after which the fishing goes on.(382) In spring, when the winds blow soft from the south and the salmon begin to run up the Klamath river, the Karoks of California dance for salmon, to ensure a good catch. One of the Indians, called the Kareya or God-man, retires to the mountains and fasts for ten days. On his return the people flee, while he goes to the river, takes the first salmon of the catch, eats some of it, and with the rest kindles the sacred fire in the sweating-house. “No Indian may take a salmon before this dance is held, nor for ten days after it, even if his family are starving.” The Karoks also believe that a fisherman will take no salmon if the poles of which his spearing-booth is made were gathered on the river-side, where the salmon might have seen them. The poles must be brought from the top of the highest mountain. The fisherman will also labour in vain if he uses the same poles a second year in booths or weirs, “because the old salmon will have told the young ones about them.”(383) Among the Indians of the Columbia River, “when the salmon make their first appearance in the river, they are never allowed to be cut crosswise, nor boiled, but roasted; nor are they allowed to be sold without the heart being first taken out, nor to be kept over night, but must be all consumed or eaten the day they are taken out of the water. All these rules are observed for about ten days.”(384) They think that if the heart of a fish were eaten by a stranger at the beginning of the season, they would catch no more fish. Hence, they roast and eat the hearts themselves.(385) There is a favourite fish of the Ainos which appears in their rivers about May and June. They prepare for the fishing by observing rules of ceremonial purity, and when they have gone out to fish, the women at home must keep strict silence or the fish would hear them and disappear. When the first fish is caught he is brought home and passed through a small opening at the end of the hut, but not through the door; for if he were passed through the door, “the other fish would certainly see him and disappear.”(386) This explains the custom observed by other savages of bringing game into their huts, not by the door, but by the window, the smoke-hole, or by a special opening at the back of the hut.(387)
