Mr. Atkins: I think I have seen that thing happen. It 
will snap at it at any rate. 
Mr. Clark: I have seen them take liver. 
Mr. Titcomb: It has been quite customary, and believed to 
be desirable at many stations to begin to feed fry before the sae 
is absorbed, sometimes giving them nothing but blood. But in 
this case I wondered just how you knew when the sac was 
entirely absorbed. I thought you judged the fasting period as 
against the feeding period by the time the fish began to take 
food rather than as to whether the sac was entirely absorbed or 
not. 
Mr. Atkins: You are correct. We go rather by the indica- 
tion of the fish as to whether they want food than by actual 
examination, to determine the absorption of the sac. Those 
have been my instructions to my assistants, to try the fish, and 
whenever they are ready for food to give it to them. But in 
general it can be said that we began about the time the sac was 
absorbed. I do not think that in case of our fish there has been 
any general anticipation of the absorption of the sac in their 
taking food, although not having studied that point very closely 
T would not ike to be certain of the absolute correctness of the 
statement. 
Mr. Titcomb: Then if the trout, in your experiments, 
came up to take food a little before the sac was absorbed, this 
experiment may have been begun a little before the sac was ab- 
sorbed ? 
A. It is possible. 
Secretary: There are some communications from members 
asking questions in regard to trout, this being the subject under 
discussion. 
1 have received with the following report a letter containing 
a question which is as follows: 
“There is one guestion, recently called to my attention, in 
relation to fish culture, which I should be very much pleased 
to have discussed by the society.
