Of the genuine salmon, we believe there is but one distinct species in the world; we are sure there is not in the United States. From its lithe beauty, its wonderful activity, and its value as an article of food, it unquestionably takes precedence of all the fish which swim in our waters. It is an ocean-born fish, but so constituted that it has to perform an annual pilgrimage into our fresh-water rivers for the purpose of depositing its spawn. Their running time usually occupies about two months, and that is the period when they are in season, and of course the only period when they are taken in great numbers. The variety of which we speak is a slender fish, particularly solid in texture, and has a small head and delicate fins. The upper jaw is the larger, while the tip of the under jaw in the female has an upward turn. The back is usually of a bluish color, the sides of a silvery hue, and the belly pure white, while along the centre of its body runs a narrow black stripe. The scales are small, and the mouth is covered with small, but stout and pointed teeth. A few dark spots are dispersed over that part of the body above the lateral line, and the females usually exhibit a larger number of these spots than the males. The tail of the young salmon is commonly forked, while in the adult fish it is quite square. To speak of the salmon as a bold biter and a handsome fish, or of his wonderful leaping powers, would be but to repeat a thrice-told tale. And now for a few words on some of the habits of the salmon. He is unquestionably the most active of all the finny tribes, but the wonderful leaps which he is reported to have made are all moonshine. We have seen them perform some superb somersets, but we never yet saw one which could scale a perpendicular waterfall of ten feet. That they have been taken above waterfalls three or four times as high we do not deny; but the wonder may be dispensed with, when we remember that a waterfall seldom occurs, which does not contain a number of resting-places for the salmon to take advantage of while on his upward journey. Contrary to the prevailing opinion, we contend that the salmon is possessed of a short memory. While fishing in a small river on a certain occasion, owing to the bad position in which we were placed, we lost a favorite fly, and it so happened that in about one hour afterwards a fish was taken by a brother angler, in whose mouth was found the identical fly that we had lost. This fish is a voracious feeder, and an epicure in his tastes, for his food is composed principally of small and delicate fish, and the sea-sand eel; but it is a fact that the _surest_ bait to capture him with is the common red worm.
