96 FISH HARVESTING. 
The great seawrack, that grows to an immense 
size in these northern seas, and forms submarine 
forests, has a hollow stalk, expanded into a com- 
plete flask at the root-end. Cut into lengths of 
about three feet, these hollow stalks, with the 
bulb at the end, are collected and kept wet until 
required for use. As the oil is obtained, it is 
stored away in these natural quart-bottles, or 
rather larger bottles, for some of them hold three 
pints. 
Some fifty years ago, vast shoals of eulachon 
used regularly to enter the Columbia; but the 
silent stroke of the Indian paddle has now given 
place to the splashing wheels of great steamers, 
and the Indian and the candle-fish have vanished 
together. From the same causes the eulachon 
has also disappeared from Puget’s Sound, and is 
now seldom caught south of latitude 50° N.
