I have thus stood over them half an hour at a time, and stroked them familiarly without frightening them, suffering them to nibble my fingers harmlessly, and seen them erect their dorsal fins in anger when my hand approached their ova, and have even taken them gently out of the water with my hand; though this cannot be accomplished by a sudden movement, however dexterous, for instant warning is conveyed to them through their denser element, but only by letting the fingers gradually close about them as they are poised over the palm, and with the utmost gentleness raising them slowly to the surface. Though stationary, they keep up a constant sculling or waving motion with their fins, which is exceedingly graceful, and expressive of their humble happiness; for unlike ours, the element in which they live is a stream which must be constantly resisted. From time to time they nibble the weeds at the bottom or overhanging their nests, or dart after a fly or a worm. The dorsal fin, besides answering the purpose of a keel, with the anal, serves to keep the fish upright, for in shallow water, where this is not covered, they fall on their sides. As you stand thus stooping over the bream in its nest, the edges of the dorsal and caudal fins have a singular dusty golden reflection, and its eyes, which stand out from the head, are transparent and colorless. Seen in its native element, it is a very beautiful and compact fish, perfect in all its parts, and looks like a brilliant coin fresh from the mint. It is a perfect jewel of the river, the green, red, 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. It is a tough and heedless fish, biting from impulse, without nibbling, and from impulse refraining to bite, and sculling indifferently past. It rather prefers the clear water and sandy bottoms, though here it has not much choice. It is a true fish, such as the angler loves to put into his basket or hang at the top of his willow twig, in shady afternoons along the banks of the stream. So many unquestionable fishes he counts, and so many shiners, which he counts and then throws away. Old Josselyn in his "New England's Rarities," published in 1672, mentions the Perch or River Partridge.
