The fact is, the}'' can be kept in confinement with the greatest 

 ease. Now, if they can be kept in a small pool, twenty-eight feet 

 long and three feet deep, what difficulty could be presented in 

 keeping them in a larger enclosure. 



Mr. Eavenel : Are they kept in a fresh water pool ? 



Mr. Bean: The water is made alternately fresh and salt; 

 they have been kept in fresh water as far north as this latitude ; 

 and they have been kept in Thunder Bolt Bay, South Carolina, 

 and fed and reared to a great size. 



Mr. Clark : It is not the fact of holding these fish and keep- 

 ing the fish themselves in good condition that is important. The 

 point is, will they develop the eggs. Now we keep the grayling 

 in a pond for years and years, but has anybody ever domesticated 

 the grayling and made a business of taking eggs from graylings 

 in ponds ? I know I have tried it a good while, but without suc- 

 cess. It is not a question of holding the fish. There is no trouble 

 about holding a great many fish, but the question is, can you pen 

 those wild fish and have the development of the eggs go on until 

 the ripe stage ? For instance, last fall with our white fish why 

 did we have a greater number of plugged fish than ever. before? 

 We had the greatest number ever known, either by Mr. Bower or 

 Mr. Downing or Mr. Strauahan at his station. 



Mr. Bryant : What do you mean by "plugged" fish ? 



Mr. Clark : Tliose that you do not get any eggs from. That 

 is, the development has stopped and the vent is plugged. Thai 

 is the common term. Last year the water was warm, and that i^ 

 the reason we had so many plugged fish. There is no trouble in 

 keeping the striped bass in good health and all that, Init the ques- 

 tion is when these fish are penned will they go on and develop? 



^Ir. Titconil): You do not understand the kind of penning we 

 propose to do. In this case in the river between the two falls is 

 where the fish lie and spawn anyway; only part of them will go 

 on through. Xow what we want to do is to put a rack across in 

 these Eapids. What is the reason they cannot live down there ? 

 They do not know they are penned until they get up against the 

 rack — they hardly know they are confined. 



Mr. Clark: I do not wish to throw any cold water on this 

 project of trying to pen the fish; I recommend that it be tried. 

 It should not only be tried in the way Mr. Titcomb suggests, but
