288 Fisnixe iy Amertcan WATERS. 
In Europe it is found desirable to cultivate this fish, as it 
is very prolific and an excellent pan-fish; but in America, 
where it is no trick to take half'a bushel a day on the ponds 
in the immediate vicinity of the city of New York, it is not 
deemed worth while to encourage its propagation. Indeed, 
so great a scourge is it regarded on Long Island, that poach- 
ers having a grudge against an owner of a trout-pond go in 
the night-time and stock it with perch. 
Of the fishes belonging to this order there are over twenty 
families, including the numerous kinds of bass, and nearly all 
of those fishes of fresh waters with the first dorsal spiked or 
spinous rayed. Of these families there is searcely a fresh- 
water river or lake on earth which does not contain a repre-

The ovarium of a perch is one fourth the weight of the 
fish; and a pound perch has been known to contain 992,000 
eggs. 
THE GLASS-EYED OR WALL-EYED PIKE. 
This is one of the fishes of the Middle and Northern States. 
At the Southwest it is called wall-eyed, while at the North it 
is known as the glass-eyed pike, and by other local and un-

its eyes being the most distinctive mark, it is more generally 
known by the names given at the heading than by any other. 
It sometimes attains to a very great weight. Doctor Buel 
took one in the Kentucky River which weighed nearly fifty 
pounds. 
They are found in all the tributaries of the Ohio River, in 
the range of great lakes, and most of the rivers and lakes as 
far east as New York, south as far as Tennessee, and west as 
far as Wisconsin. They also inhabit many of the waters in 
the western part of the Dominion of Canada. In Cayuga, 
Seneca, and other lakes of the western part of New York they 
are often taken, sometimes weighing as high as forty pounds. 
In Oneida Lake they are numerous; in fact, the glass-eyed
