hatching yellow perch. I did it as an experiment. I was en- 
gaged in another work, but I had a chance to get a few of the 
eggs, and I carried them from North Bass Island to Sandusky, 
ina pail andina pan. When I got to Sandusky I found a large 
part of the eggs stuck to the bottom of the pan, and I saw that 
if I removed them from the pan I would injure them, and I left 
them in the pan and turned a small stream of water on them and 
arranged them so that the water would go into a screened box; 
and the others I put into a jar. In putting them into the jar I 
let them wind right around the tube, and in eight days they 
hatched, and so far as I could see they hatched 100%. I did not 
see that any died or were wasted; and it seemed to me at that 
time, that it was a very easy matter to hatch that kind of fish. 
Mr. Harron: I would like to ask Mr. Downing if he noticed 
the temperature of those that hatched in eight days. 
Mr. Downing: Pretty high—about 70°. That was some 
time ago and | do not exactly remember the temperature. 
Mr. Harron: My experience is that it takes the yellow 
perch egg 10 to 20 days to hatch out at a mean temperature of 
47> to 54°. 
Mr. Townsend: We have had a half bucket full of eggs 
which kept in good condition and 30,000 to 50,000 hatched out 
each season. 
Mr. Buller: How far had the eggs advanced? 
Mr. Townsend: They hatched pretty promptly. The fur- 
ther the eggs are advanced the harder it is to transport them. 
Mr. A. G, Buller: That was the trouble with the eggs that 
Mr. Meehan took; they were hatching on the way; and also 
with those that I sent to Bellefont—they were practically all 
hatched out. The eggs Mr. Nathan Buller spoke of were green 
eges and not difficult to carry; but as for carrying them any 
distance on trays when they are ready to hatch I do not think it 
can be successfully done. 
Mr. Meehan: There does not seem to be any limit in reason 
to the number of yellow perch that may be carried. You can 
carry nearly as many yellow perch in a pond as you can of trout
