Rh coppery, and golden reflections of its mottled sides being the concentration of such rays as struggle through the floating pads and flowers to the sandy bottom, and in harmony with the sunlit brown and yellow pebbles. Behind its watery shield it dwells far from many accidents inevitable to human life.

There is also another species of bream found in our river, without the red spot on the operculum, which, according to M. Agassiz, is undescribed.

The Common Perch, Perca flavescens, which name describes well the gleaming, golden reflections of its scales as it is drawn out of the water, its red gills standing out in vain in the thin element, is one of the handsomest and most regularly formed of our fishes, and at such a moment as this reminds us of the fish in the picture, which wished to be restored to its native element until it had grown larger; and indeed most of this species that are caught are not half grown. In the ponds there is a light-colored and slender kind, which swim in shoals of many hundreds in the sunny water, in company with the shiner, averaging not more than six or seven inches in length, while only a few larger specimens are found in the deepest water, which prey upon their weaker brethren. I have often attracted these small perch to the shore at evening, by rippling the water with my fingers, and they may sometimes be caught while attempting to pass inside your hands.
