and one or two a little over four pounds. We have never had 
any of that weight in our ponds. 
We have had California trout for fourteen or fifteen vears, 
and in that case the female seemed to have greater vitality than 
the male, and lived longer. We had a few specimens of the 
California trout which we carried through to that age, and in 
each case the female ceased to spawn at about twelve vears. 
At our Corry hatchery they thrived better than at some other 
hatcheries. 
We have some lake trout in our ponds that were there nearly 
thirty years ago, and were young fish at that time. 
Secretary: It is strange but true that there seems to be no 
data giving the age of trout. 
Mr. Dinsmore: I have been waiting for some one to speak 
of the cannibalistic nature of the black spotted trout. I will 
not make positive statements, but I have frequently found black 
spotted male trout so gorged with eggs, that I have taken them 
off the beds and attempted to strip them for females. 
In connection with these very lakes about which the gentle- 
man has asked a question, | came from them last Monday, and 
just below the troughs where we were eyeing the eggs over into 
the lake, and there the big schools of black spotted trout were 
eager to pick them up. I presume they would have picked them 
up just the same if they had been live eggs. 
Mr. Titcomb: I can answer that question, about the canni- 
balistic nature of the trout, or the tendency of the male trout 
to eat the eggs of the females. | observed one small bed under 
a rock in a lake in Canada, where a person could look down and 
see the performance of the fish. Twenty-seven trout were taken 
off this spawning bed, although there were but two females 
which were in spawning condition, a few spent females, and the 
balance were males which were there eating the eggs as fast 
as they came from the female. 
Mr. Hubbard: Did you not observe the female eating the 
eges as well as the males? 
Mr. Hubbard: Yes, the spent females. 
(). And would not some of the females eat their own eggs 
after spawning? I have seen brook trout do that. 
A. Yes, sir, I understand that is an accepted fact.
