and yet from a small plant made in this lake about the 
year 1885 we learn that adult fish have been taken. 
All fishculturists who attempt to keep up their stock 
of parent fish by raising a certain quantity of fry each 
year are familiar with the great mortality occuring at the 
period when the young fish has finally absorbed his food 
sac, and is ready to take the natural food provided by 
nature. At this time when he “rises” in search of this. 
natural food if he does not find it he is compelled to take 
the artificial food prepared for him, and the difficulty of 
adapting his stomach to this food results in a loss which 
varies somewhat from fifty to seventy-five per cent. If 
the young trout at this period of his existence were 
allowed to forage for his natural food this mortality would 
be greatly reduced. There are streams that are well 
known in Michigan which have had plants of fry not to 
exceed five hundred in number which within three years. 
from the time of stocking have shown up well, and to-day 
without further stocking afford good sport to the angler. 
Within the current month there appeared in the Detroit 
daily paper an interview with a prominent fishculturist 
who took occasion to say “I believe, and against great 
opposition have always maintained, that 100,000 yearlings. 
planted were more likely to live and thrive than 5,000,000. 
fry.” Making due allowance for the enthusiasm of the 
interviewed party and for the natural predisposition of 
man to defend his pet theories, let us see where these 
figures would leave us. 
We will start with 5,000,000 fry planted, and we will 
say that twenty-five per cent. perished the first year, ten 
per cent. the second year, and five per cent. the third year. 
At the end of the second year after deducting the twenty- 
five per cent. for loss, and estimating the number thus left 
to be composed of one-third females, which would cast 
on an average 250 eggs apiece, there would be added to 
the stock 281,250,000. Estimating that there will be a
