so used milt of the brook trout. These fish are now upwards of 

 a year old and show to a certain extent the characteristics of both 

 parents. They have to a lesser degree than the brook trout the 

 black line inside of the white margin on the fins. As to the 

 marbling, of course we cannot tell whether that will disappear 

 or not, but it is very plain now. They are not quite so slender 

 as the saiblings but are more slender than the brook trout, and 

 are very uniform in appearance — almost as uniform as any of 

 the species. There is not a very great difference as to size — not 

 more so than would be found amongst any fish of the san^e age. 

 They do not feed in quite as great a depth of water as the golden 

 trout, and yet lower than the brook trout. Our golden trout in 

 the ponds, as I stated in my paper, huddle in some dark corner. 

 The ponds we have kept them in have plank bottom, covered 

 with sand, and they swim so low that in a very few days the 

 movement of the fins brushes that sand all away, leaving the 

 bare surface of the boards exposed. While our hybrids swim in 

 much the same manner, they do not work the sand off so quickly, 

 they have partaken almost equally of the characteristics of each 

 of the parents, and show very decided resemblance to each of 

 them, being half way between the two varieties, and I think it 

 would perhaps l:>e interesting for some of our scientists, if they 

 would examine them more critically than we fish culturists can. 



Mr. Xevin: What is the fact as to the shedding of teeth 

 during the spawning season? 



Dr. Bean : 1 heard it reported frequently, but I have never 

 made the observation myself. Of course the shedding of teeth 

 during the l)reeding season is not at all uncommon. jMany fishes 

 do that. 



Mr. Nevin : They do not do it during the breeding season. 



Dr. Bean: The pike-like fishes and salmon are not very far 

 a])art in a good many respects, and I should expect to find that 

 the i)ike and muscalonge, which belong to the same family, 

 would show much the same habit as some of the salmon — that 

 appears to be related to the s])awiiiiig time. 



Mr. Waterhouse : Can that hybrid trout breed ? 



Dr. Bean: Oh, yes, it is quite fertile, and so is the cross l)i'- 

 tween the brook and the lake trout, but they are so closely related 

 <renc]-icallv that there is no reason whv thev sliould not l)e.
