in (litferont regions, but was unable to find any local differences. 

 Xow, in the case of some of the marine fishes, those local differ- 

 ences are very noticeable, and by making such studies it is possi- 

 ble to locate local races. The whitefish s^iawn in the western 

 end of the lake in the fall, and that would obliterate local races 

 by interbreeding. 



On the other hand, this same man. Dr. Ea_vmond Pearl, has 

 gone this year to the northern end of Lake ^Michigan and is at 

 Charlevoix now. He has been measuring the whitefish there and 

 he finds very distinct evidences that they form a different race. 

 This race is very markedly different in its measurements from 

 that of Lake Erie. Of course that is nothing more than the 

 fishermen have said for many years, that they could tell I^ake 

 Erie whitefish from Lake Michigan whitefish, l)ut so far as 

 scientific evidence goes it is all there is, I think. 



The President : Is there not a whitefish called a bluefish ? 



]\Ir. Clark : Yes, sir, but that is not the fish under discus- 

 sion. 



I would like to ask Prof. Peighard whether his investigator 

 at Charlevoix has examined a sutficient number of specimens to 

 know wliether he may not have had some fish that were planted 

 there and had increased in size. 



Prof. Reighard : That was one of tlie things had in mind in 

 sending liim up there, l)ut as far as I can learn he has no evi- 

 dence on that })oint. It ought to l)e possible to find ])y this 

 method trace of Lake Erie whitefish planted up there, but he has 

 not got them yet. That may come out when he reaches the final 

 discussion of Ins results. 



.Ml'. Clark: This could lead into a great many questions we 

 would like to ask, but I do not know as we ought to take up the 

 1 inie. 



'I'he President: It is a very interesting topic to us who are 

 situated on the great lakes.
