TENTH ANNUAL MEETING. if

from three-fourths to one pound each. Last November they 
commenced to spawn for the first time. They commenced the 
first and continued until the 12th of November, during which 
time we succeeded in taking 19,400 spawn, the males and females 
both being fertile. The eggs hatched in about ninety days, the 
season being prolonged by the unusual cold winter. The yolk 
sack has now disappeared and the young fry are feeding and 
doing well. The question now arises, Will they be capable of 
reproducing their own kind? My opinion is they will, but time 
will tell. I shall endeavor to put a few thousand into some of 
our lakes and streams and thus determine to what waters they 
are best adapted. 
My next most successful experiment was with the cross be- 
tween the California salmon and brook trout. They are now 
four years old and, like the salmon trout and brook trout hybrids, 
resemble both parents. The cross was made with female brook 
trout and male California salmon. Nearly all the fish have a 
deformed appearance ; a few of them are perfect fish. Last sea- 
son they exhibited signs of spawning. There were either no 
males among them, or, if there were, they were not fertile. On 
attempting to take the spawn from them the vent was found to 
be too small to pass the eggs. The aperture was enlarged and 
spawn taken and impregnated with brook trout milt. None of 
them hatched. The eggs were nearly the size of salmon eggs. 
The parent fish have done well and some of them will weigh 
nearly, if not quite, two pounds. I do not think this cross will 
ever amount to anything. The salmon used were those kept in 
confinement and not as large or in as good condition as in their 
natural state. I am of the opinion that if the perfect salmon 
and brook trout could be brought together a perfect cross might 
be made, or at least the experiment would be worth trying. 
I have made several other experiments in hybridizing, such as 
crossing the hybrids with brook trout and also crossing them 
with salmon trout. I have also crossed the brook trout with the 
California mountain trout, all of which have been attended with 
more or less success. I have this season been trying a series of 
experiments in impregnating the eggs of brook trout, the results 
of which will undoubtedly be interesting to the society. My
