The siskawit, a fish of Lake Superior, Is reported to be the fattest fish that swims either in fresh or salt water. The fishermen say that one of these fish, when hung by the tail in the hot sun of a snmmer's day, will melt and entirely disappear except the bones. In packing about fifty barrels, a few seaSOnS ago!at Isle Royale, one of the fishermen made two and a half barrels of oil from the heads and leaf fat alone, without the least injury to the marketableness of the fish. Besides this leaf fat, the fat or oil is disseminated in a layer of fat and a layer of lean throughout the fish. They are too fat to be eaten fresh, and are put up for market like the lake white fish and Mackinaw trout.
