176 Thirty-fifth Annual Meeting 
ing the ponds natural, and possibly putting in manure of some 
kind until we introduce the little fish where nature has already 
provided food which carries them along until they take some- 
thing larger. 
Mr. Lydell: We have no trouble here in getting plenty food 
for the fry. The trouble arises after they become an inch long, 
or a little less; that is where we lack for food. Our food was 
most plentiful this year in ponds which had been dry during 
September and October. Those ponds this year were one teem- 
ing mass of daphnia. We put in our small bass fry and after 
they were three-fourths of an inch long they cleaned up the mass 
and then they lacked food. 
Mr. Titcomb: That is where maggots would come in. 
Q. Do you keep any of your ponds dry through the winter? 
A. No. 
Q. Just through the fall ? 
A. We had to run them dry on account of putting this wall 
in—that was the only reason. 
Mr. Titcomb: I have heard of a food used called the Chi- 
cago food, and I would like to inquire what that is. 
Mr. Meehan: It looks a little bit like Indian meal. 
Mr. Lydell: Yes. 
Mr. Meehan: We tried it on trout and it bound them up 
like a bullet. 
Mr. Lydell: We had some bass in the same pond; there was 
a nice current formed through the screen and by stirring this 
food up it went down this current and looked as much lke 
daphnia as anything you could get, and I thought it would be 
quite valuable, but these bass would just give it a wise look and 
walk away, and they would starve to death before they would 
take it. 
President: Are there any further recommendations of this 
Chicago food ?
