large pills, each sufficient to give one meal to five boxes. 

 . . . When the food is all prepared it is taken to 

 the hatching-house and one pill placed on the edge of. 

 the fifth box in each row. One of the girls then goes 

 round with a feeding spoon, and, beginning at the bot- 

 tom box, presses the food through the perforated zinc 

 of the feeding spoon, which reduces it into fine vermi- 

 celli. When the threads are about two inches long 

 they are shaken off into the water. ..." ' 



In 1891 I sent circulars to several trout breeders 

 asking a few questions. They were : "3. On what do 

 you feed the fry for the first three months, and how?" 

 "4. What do you consider to be a fair percentage of fry 

 brought through the first six months, reckoning from 

 the time of their first taking food?" "5. Do you feed 

 fry in hatching troughs ? If so, how long ?" Here are 

 some answers : 



Charles G. Atkins, Superintendent of Salmon Hatch- 

 ing Station, U. S. F. C, East Orland, Me. — "3. In 

 troughs on chopped liver for one month or six weeks, 

 then part on same food and part on maggots ; majority 

 on maggots this year. From July 15 to 30, 1891, have 

 fed about 200,000 on maggots. 4. Sixty per cent. ; 

 but we have done much better. In 1889, out of 109,- 

 965 Atlantic salmon eggs, counted in winter and early 

 spring, we saved until the next October 91,856, or 83 

 per cent., actual count at start and finish; that is my 

 very best. 5. All summer and fall, sometimes through 

 the winter." 



E. M. Robinson, Superintendent U. S. F. C, Mam- 

 moth Springs, Ark. — "3. Beef liver, but don't approve 

 it. 4. Seventy-five per cent. 5. No; we use ditches 

 5 feet wide, 15 to 20 feet long, and shaded half way 

 the length."
