The salmon is what is called _anadromous_--that is, though an inhabitant of the ocean for most of the year, it ascends the fresh-water rivers in summer to spawn. In this function it is guided by curious instincts. The female deposits her eggs in swift shallow water at the heads of streams, in trenches dug by herself and the male fish in the gravelly bottom; but it must not be fresh gravel: it must have been exposed to the action of water for at least two years, or they will have none of it; and if a freshet should bring new gravel from the banks, they will abandon the place and seek for new spawning-grounds. It is only when the salmon are resting in these pools that they will take a fly. The first pool was at a point where the river made a short turn around a large rock: the current was swift, with a hole at the foot of the rapid perhaps twenty feet deep, with a rock bottom. Here our leader, Kingfisher, rigged his salmon-rod, put on two flies and began to cast. I trolled in the swift water as we proceeded, and with my spoon took a few small trout. A salmon rose to the fly of Kingfisher, but was not hooked; this was the first fish that we saw. (The term "fish" is always applied to the salmon by anglers: other inhabitants of the water are spoken of as "trout" or "bass;" a salmon is a "fish.") Although we had seen none before, our keen-eyed Indians had seen many as we came up the river. We then went on to the Lower Indian-house Pool, two miles farther, and Kingfisher made a few casts; but raising no fish, we went up a mile farther to our camping-ground, an island between the two pools, having plenty of wood upon it, with a cold spring brook close by--an old and famous camping-place for salmon-fishers--and here we intended to make our permanent quarters. We had four tents--one to sleep in, fitted with mosquito-bars; one for an eating-tent, with canvas top and sides of netting: in it was a rough table and two benches, hewed out with an axe by one of our men. There was also a tent for storing provisions and for the cook, for we had brought with us a man for this important office. A fourth tent for the Indians, and a cooking-stove with camp-chests and equipage, completed our outfit, which all belonged to Kingfisher, and represented the results of many years' experience in camping out. The cooking-stove is made of sheet iron and packs in a box, and is one of the most valuable utensils in the woods. It took the rest of the day to make the camp, and in the evening Kingfisher and the Colonel went in their canoe to the lower pool, and the former killed two salmon, weighing eighteen and twenty-two pounds. These, our first fish, were objects of much interest to us new hands. The Colonel took his first lesson in salmon-fishing, and thought he could do it himself.
