“The Candle-Fish of British Columbia”

There is found, in some of the rivers of British North America, a species of smelt so rich in oil that it may when dried be used as a candle or torch. … At certain seasons the fish swarms up the rivers from the sea, and is then caught by the natives in wickerwork traps. … When a candle is required a dried fish is stuck, tail upwards, in a lump of clay or in a cleft stick; a light is applied to the tail, which instantly flames up, and the fish burns steadily downward, giving a light superior to that of the best quality of ‘dips.’
