Whitefish . — Eggs were collected at Toledo and the Lake Erie islands 
from November 3 to November 28, 1888. On November 8 and 9 the 
temperature was 14° higher than upon these dates in 1887, and 
75,600,000 eggs were lost thereby; /the loss was made good by later col- 
lections. Eggs were distributed as follows:

Forty million seven hundred thousand whitefish were hatched at 
Sandusky and the fry deposited in the western end of Lake Erie, from 
March 22 to April 1, 1889. 
Pike perch. — Eggs of this species were collected from April 10 to 25, 
1889, at Toledo and the islands. About 90,000,000 were obtained, of 
which 60,000,000 were hatched; but 10,000,000 were lost through lack 
of facilities for shipping them. Eggs have been taken at Sandusky 
during six years ending with 1889, but never before in such large num- 
bers. The following distribution of fry was made:

QUINCY STATION, ILLINOIS. 
During the winter of 1887-88 the attention of the Commissioner was 
attracted to the work done by the Illinois State fish commission in the 
collection and distribution of the native food-fishes of the Mississippi 
Basin. The overflow ponds and lakes formed during the seasons of 
high water are the fruitful nurseries of the young of the crappies, th« 
basses, the pike perch, the yellow perch, and the spotted catfish. Here 
they grow rapidly, until, with the contraction of the water areas and 
the increasing demands for food, the waters become overstocked and 
they die in countless thousands by starvation, or perish by the drying 
up of the ponds during the season of summer drought. It was recog- 
4 nized that these natural nurseries furnished ready to our hands, at little 
comparative cost, an immense supply of choice food- fish and well adapted 
by their habits and conditions of life to the more sluggish streams of
