I never caught salmon-fry whilst fishing for trout, as we could so easily do in our streams; and it is just possible that the rapid rise (unlike anything we know of in our streams) that takes place in every river, brook, and rivulet during midsummer, when the snow melts on the hills, reducing the temperature of the water down to freezing-point, may send the young salmon-fry into the saltwater at a very early period of its life. “At three days old he is nearly two grains in weight; at 16 months old he has increased to two ounces, or 480 times its first weight; at 20 months old, after the smolt has been a few months in the sea, it becomes a grilse of 8½ lbs., having increased 68 times in three or four months; at 2⅔ years old it becomes a salmon of from 12 to 15 lbs. weight, after which its increased rate of growth has not been ascertained; but by the time it becomes 30 lbs. in weight, it has increased 115,200 times the weight it was at first.”[2] These smolts that I have seen in shoals were about half an ounce in weight, the produce of the summer’s spawning. As I have stated, they disappear when the floods set in; and nothing more is seen of them until they return salmon of various sizes, from 2 lbs. to 75 lbs., or, as I believe, the Quinnat and Stzoin. The next salmon in importance, as affording food to the Indians, is called by them at the Kettle Falls _cha-cha-lool_, and arrives with the quinnat. This is unquestionably a fully-matured fish, and a distinct species, answering in many particulars to the _Salmo Gairdneri_ of Sir J. Richardson, F. B. A., ‘Fishes,’ p. 221; it will be as well to retain that name. It may be readily distinguished from the quinnat by its rounded blunt-looking nose, shorter and much thicker head, straighter back, and more slender figure—the tail not nearly as much forked. The entire colour of the back is much lighter, and thickly freckled, as are the fins and tail, with oval black spots. The average weight of the _cha-cha-lool_ is from 8 to 11 lbs. This salmon is common in the Fraser, Chilukweyuk, and Sumass rivers, and in every stream along the mainland and island coasts up which salmon ascend. When they first arrive the flesh is most delicious—fat, pink, and firm withal, and to my palate finer than that of the mammoth quinnat. The Indians also prize these salmon, and pack them when dried in bales apart from the others. _Salmo Gairdneri_ and _S. quinnat_ are the spring salmon, but the autumn has also its supply of ‘swimming silver,’ quite equal to that of spring in point of numbers, but inferior in quality. Up the Columbia in October to the Kettle Falls, and somewhat earlier in the Fraser and rivers north of it, comes an ugly, unprepossessing, hook-nosed, dingy-looking salmon, called by the Colville Indians _Keasoo_, by the Chinooks _Ekewan_, by the Clallams _Kutch-kutch_—the _Hooked Snout_ of the fur-traders, _Salmo lycaodon_ of Pallas, _Zoog.
