I have been fishing to-day, and, while enduring some poor sport, indited in my mind the following information, for the benefit of my piscatorial friends. The days of trout-fishing in Lake Horicon are nearly at an end. A few years ago it abounded in salmon-trout, which were frequently caught weighing twenty pounds, but their average weight at the present is not more than one pound and a half, and they are scarce even at that. In taking them you first have to obtain a sufficient quantity of sapling bark to reach the bottom in sixty feet of water, to one end of which must be fastened a stone, and to the other a stick of wood, which designates your fishing ground, and is called a buoy. A variety of more common fish are then caught, such as suckers, perch, and eels, which are cut up and deposited, some half a peck at a time, in the vicinity of the buoy. In a few days, the trout will begin to assemble, and so long as you keep them well fed, a brace of them may be captured at any time during the summer. But the fact is, this is only another way for “paying too dear for the whistle.” The best angling, after all, is for the common brook trout, which is a bolder biting fish, and better for the table than the salmon-trout. The cause of the great decrease in the large trout of this lake is this—in the autumn, when they have sought the shores for the purpose of spawning, the neighbouring barbarians have been accustomed to spear them by torch-light; and if the heartless business does not soon cease, the result will be, that in a few years they will be extinct. There are two other kinds of trout in the lake, however, which yet afford good sport—the silver-trout, caught in the summer, and the fall-trout. But the black-bass, upon the whole, is now mostly valued by the fisherman. They are in their prime in the summer months. They vary from one to five pounds in weight; are taken by trolling and with a drop line, and afford fine sport. Their haunts are along the rocky shores, and it is often the case that on a still day you may see them from your boat swimming about in herds, where the water is twenty feet deep. They have a queer fashion when hooked, of leaping out of the water for the purpose of getting clear, and it is seldom that a novice in the gentle art can keep them from succeeding. But alas, their numbers also are fast diminishing, by the same means and the same hands that have killed the trout. My advice to those who come here exclusively for the purpose of fishing is, to continue their journey to the sources of the Hudson, Schroon Lake, Long Lake, and Lake Pleasant, in whose several waters there seems to be no end to every variety of trout, and where may be found much wild and beautiful scenery. The angler of the present day will be disappointed in Lake Horicon.
