suggests the planting of fish before they lose their sac, 

 which I entirely agree with, and which I have reason 

 to believe is a good thing. For the last two years we 

 have been planting our trout before the sac has been 

 fully absorbed. The result is that you get a good, 

 strong, health}^ fish, and when he swims out he is able 

 to take his natural food. To discover when fish begin 

 to feed, we have instituted some experiments in regard 

 to white fish. We have taken them as soon as hatched 

 and put them into receptacles, so arranged as to permit 

 the free ingress of water with the natural food it car- 

 ries, and we then made examinations under the micro- 

 scope of the contents of the stomach of these fish. On 

 the third day our commission was engaged, and we did 

 not give the matter attention, but at the end of the 

 fourth day they found that some of the young fish 

 were taking the daphnia and that sort of thing from 

 the water. At the end of the sixth day they found 

 that food in the stomach of every one, and the sac was 

 not yet absorbed. This was with white fish. 



Mr. Cheney : How about trout ? 



Mr. Whita'ker: We never tried it with trout. 



Mr. Cheney : Would you plant the trout before 

 the sac is absorbed ? 



Mr. Whitaker: We do, and have done for the last 

 two years. The result is that in taking fish out at 

 that age we have lost almost nothing in transportation.- 

 We believe, beyond all doubt, that it is a good thing. 

 There are some other points in connection with the 

 paper that come to mind, but I will not occup}^ the 

 time of the meeting an}- further. I think the thanks 

 of the Society are due to Dr. Bean for submitting the 

 translation of this paper to us, and when we have 

 opportunity to look it over we shall be glad to do so. 



Mr. Titcomb: One subject that has been referred 

 to by Mr. Whitaker has somewhat shattered my hopes. 

 Up to this year it has been the custom of the fish com-
