Its body is elliptical in outline, about twice as long as broad, and very much compressed or flat. The head is small, less than a fourth of the length of the body, with a small mouth containing closely set, incisor-like teeth. As usual with all of the flatfishes, the dorsal and anal fins are very long, horizontally, the color on the exposed or right side is rusty brown, obscurely mottled, with the under or left side white. The flounder is partial to sheltered coves and quiet bays, preferring bottoms of sand or mud, though sometimes it is found in rocky situations. It is sedentary in its habits, partially burying itself in the sand or mud, where it remains during the entire year, feeding on minute shells, crustaceans, worms, etc. It spawns in the spring, during March and April. The eggs are very small, about thirty to the inch; and unlike those of most marine fishes they do not float, but are heavy enough to sink, forming bunches or clusters on the bottom, adhering to the weeds, etc., where they hatch in from two to three weeks. The fry swim upright, like other fishes, with an eye on each side of the head, but as they grow older they incline to one side, the under eye moving gradually to the upper side, so that at the age of three or four months both eyes are on the upper side, as the result of a twisting of the bones of the head. The right side, being constantly exposed to the light, becomes darker or colored, while the left side, being deprived of light, becomes pure white. It is an excellent food-fish, its flesh being firm, white, and of good flavor; and as it is easily procured in winter when other fishes are comparatively scarce, it is a favorite at that season. It rarely grows to more than a foot in length or a pound in weight. As it can be caught in early spring, late fall, and winter, when other fishes are absent or not inclined to bite, the angler with light tackle may obtain considerable sport with this fish, as it will eagerly take almost any kind of natural bait. A bait-rod used for trout or black-bass or a light cane rod can be utilized, with very fine linen line, a three-foot leader, and hooks Nos. 7 or 8, on gut snells; a reel is not necessary, but is convenient. Using as light a sinker as possible, with clam or sandworm bait, the angler may be assured of success. The fishing may be done from a boat anchored at low tide on muddy or grassy flats, or from wharves or piers favorably located. THE SMELT (_Osmerus mordax_)
