personal observation, which are, so far as I can see, reliable. The 
young fish, when ready to feed, were tried upon various diet. 
Liver alone was used, liver and cream mixed together, beef, beef- 
heart, curd, etc. Any one of these was taken voraciously. In 
fact, not the slightest trouble was experienced in getting the fish 
to eat. The only trouble was to feed them enough. They seem 
to grow while young faster than the salmon or brook trout, and 
of course feed in proportion. It is known that adult fish, or those 
nearly grown, may be kept for a long time at very nearly the 
same weight by feeding them but little food. This is not the 
case with young fish, as a certain rate of growth must be kept up 
or they will die. For instance, if at any time one pound of liver 
per day gives food enough to a certain number of young salmon- 
trout, in two weeks’ time, if fed on the same amount of food, they 
would not continue of the same size, but would nearly all die . 
The food must be continually increased in quantity. 
The experiments were made in the press of other work, and 
therefore were not perfect. But even with some inevitable neg¬ 
lect, at one year of age the trout averaged six inches long, and if 
they had been fed as much as possible would have been two or 
three inches longer. In two years the fish had doubled in size, 
and were all handsome, bright, and healthy fish. They are an 
easy fish to raise, and those who wish to go into the business of 
raising brook-trout are recommended to commence with the 
salmon-trout, as the methods of hatching and growing are similar 
A beginner will be far more likely to succeed with the salmon- 
trout, and thus gain the neceessary experience for raising brook - 
trout. 
Only a small appropriation has been made yearly by New 
York state, and it has been impossible to do much. Some of the 
larger inland lakes have been partially stocked. No very great 
results can be expected from this small scale of operations. Still 
the experience and training which it afforded makes us ready to 
enter successfully into larger labors. Besides this, public opinion 
has been educated and directed until we believe that now but 
few voices would be lifted against the attempt to thoroughly 
restock every lake in the state; and without the public senti¬ 
ment in our favor we could do nothing. It has been only three
