to and will not readily take the live food that may be in 
the stream. Has any fishculturist ever cast the fly in a 
pond of large fish that have been fed artificially and been 
unable to get a rise, or has he thrown grasshoppers or 
in fact any live food of whatever nature but it would be 
readily taken ? 
If it could be proven—though it cannot—that natural 
food is indispensible to the rearing of yearlings for dis- 
tribution, then under circumstances that are favorable, 
the food for growing fish may be bred with as much care- 
as is used in breeding the fish, and undoubtedly with far 
less expense than in feeding liver. This, however, would 
naturally require a large area of ponds and a large supply 
of water. 
With the work of procuring eggs, laying them down 
in the hatchery and turning out the fry, we have long 
ago passed the experimental stage and have arrived at 
the practical side of the question with the salmonide. It 
only depends on the question of parent fish as to the 
number of fry to be hatched; neither does it require a 
scientist to do this branch of fishculture work, but a 
good, practical man. Therefore, with the rearing of 
trout to-day, the principal question that should occupy 
the minds of advanced fishculturists is: what should be 
used for food and how to procure it. 
Every observing and thoughtful fishculturist knows. 
that many of our inland lakes have been planted with 
hundreds of thousands of whitefish fry and only a very 
few have been stocked. If we raise the whitefish fry to. 
be one year old and plant them in these lakes, is it not 
possible and probable with the results before us, that we 
may be successful in stocking many more bodies of 
water than the fry work has accomplished? At any rate, 
is it not worth the trial? Experiment by practice is part 
of a fishculturist’s work. 
One of the proposed improvements at the Northville 
Station is that of constructing a rearing pond for white-
