ery, pike perch might be hatched to take care of the pike perch water 
south of Chicago. 
It has been suggested that a hatchery and aquarium be built near 
the lake in one of our city parks. This would be a splendid location 
for a hatchery as the distribution could be done by boat. Aside from 
its purely practical feature as a fish hatchery, the plant would have 
an attractive feature which would be appreciated by the public, more 
especially if there was an aquarium operated in connection with the 
hatchery. There is no doubt but what a fish hatchery, where lake 
trout would be hatched in the winter, and pike perch and white perch 
in the spring, would prove a great attraction, thus serving a double 
purpose at one cost. 
In addition to breeding lake trout, pike perch and white perch 
at a park hatchery, a large number of bass might be hatched to sup- 
ply some of the waters south of Chicago. 
There is no doubt but what the best all-round game fish for 
Illinois is the large-mouthed black bass. This fish does well in the 
lively waters of the northern part of the State and thrives in the 
more sluggish waters of middle and southern Illinois. So far, the 
State has hatched this bass exclusively. But there are waters in 
which this fish will not do well, whereas such waters are peculiarly 
suited to the small-mouthed black bass. 
The large-mouthed variety of the bass is essentially a lake or 
pond fish. The small-mouthed variety is a river or creek fish, prefer- 
ring running water in streams with a gravel and stone bed. 
As we have many streams of this kind, unsuited to the large- 
mouthed black bass, it would appear to be the part of wisdom to begin 
to think about a small-mouthed bass plant to take care of these waters. 
The Kankakee River, for example, is a small-mouthed bass stream. 
There is a good flow of water in this river, and an almost continuous 
fall from the Indiana line to the end of the river. There is an 
abundance of crayfish in this water, a kind of food especially suited 
to the small-mouthed bass. 
There are a few places on the Kankakee River where the large- 
mouthed bass will thrive, but the greater part of this stream should 
be stocked with small-mouthed bass and pike perch. 
There are a few tributaries of this river, where the small-mouthed 
bass will thrive. And then there are other streams in the State where 
this fish will do well, whereas the large-mouthed variety will not. It 
would be well, therefore, to take up the breeding of the small-mouthed 
bass for the purpose of stocking such streams as are peculiarly suited © 
to this fish. 
One of the most important of our commercial fishes is the buffalo 
fish. For a number of years the supply of this fish has been steadily 
decreasing. While it is of a similar type to the German carp, it is 
not quite so hardy, and does not appéar to be able to keep pace with 
the carp in the struggle for existence. In recent years the increased 
value of land along the Illinois River and other large streams has 
made it advisable to reclaim thousands of acres of land that formerly 
furnished good breeding and feeding waters for fish. The buffalo 
fish has suffered more on account of the reclaiming of overflowed
