 Mass. "3. Sheep livers. 4. Forty per cent. 5. Don't 

 feed in hatching troughs*'' 



Just before going to press these questions and an- 

 swers were returned to the writers for correction after 

 eight more years' experience, but none of them made 

 any. A letter from Mr. G. Hansen, Osceola, Wis., 

 March 26, 1899, says: "I feed fry up to one year old 

 on beef liver and milk curd, mixed in the proportion of 

 two parts liver to one of curd. I feed in troughs from

 good success, but prefer putting them in a nursery pond 

 in May. The green slime, algae, bothers me some in 

 the hatching house by clogging screens, therefore I re- 

 move the fry. The wild fish give the best eggs/' 



COMMENTS ON THE METHODS OF FEEDING.

 let me say : There is nothing better than liver of beef, 

 or perhaps other animals, from the start. Maggots are 

 as good after the fish get big enough to swallow a full- 

 grown one, and they do not drop until they are full

 while curd may be of value, I don't take a cent's worth 

 of stock in any admixture of vegetable matter. Under 

 my management of the New York hatchery on Long 

 Island, the yearling trout, at twelve months old, meas-

 could show such trout. This was partly owing to 

 crowding the food to them and partly to the tempera-
