Black bass are taken among the Thousand Isles in immense numbers, but not of any great size, rarely exceeding three pounds. In Lake Champlain, near Rouse’s Point, and in the lakes of Canada, they grow larger. The largest, probably, never exceeding eight pounds. They are taken in most of the waters of the northern and northwestern States, especially in the Niagara and Detroit rivers, Lake St. Clair, Lake Erie and Lake Huron. They make their appearance from deep water in May and June, grow to great excellence in July and August, but are in their best condition in September and October. They are a fine, noble game fish, and where trout are not to be had are well worthy of the sportsman’s attention; when captured, which can only be done by skill and care, they prove an excellent addition to the table.

The fish usually known as trout at the South, albeit that name is applied to many varieties, is a species of black bass, and is taken by trolling with a rod and short line before the boat as it is rowed along.

CHAPTER XXIII.
ROCK BASS.

Centrarchus Æneus.—This is an entirely distinct species from the Black Bass, though, being somewhat similar in color and shape, is often confounded with them. The same may be said of the Oswego Bass, which is now ascertained to be equally distinct, though commonly known as bass, and supposed to be identical. The fish under consideration must in no wise be confounded with the Rock-fish of Pennsylvania, which is the Striped Bass, Labrax lineatus, and which the benighted Pennsylvanians would oblige us by calling by its right name.

The Rock Bass has two flat points at the angle of the gill-cover, and is distinguished from the variety last described by six or seven spines and eleven soft rays in the anal fin. The dorsal has eleven spines, and ten or twelve soft rays; the pectoral fourteen soft rays, the ventral one spine and five soft rays, and the gill-rays are six. The fin-rays are given by Dr. De Kay as follows:

D. 11.12; P. 14; V. 1.5; A. 6.11; C. 17-3/3.

This fish is found in much the same waters as the black bass, and, like the latter, made its way on the completion of the Champlain canal through it into the Hudson River. It takes any of the ordinary baits, preferring, however, the cray-fish, Astacus Bartoni, and can be
