60 Thirtieth Annual Meeting 



what lias Ix'i'ii done with other fisli. I say that in all prohahility 

 we can account for the condition of affairs in Lake Erie by the 

 increased number of fishermen going there for the reason that it 

 is better fishing. 



Mr. Clark: But it is Ijetter fishing there because there are 

 more fish. 



Dr. Parker: We do not know wliethor that is the result of 

 planting or of natural causes. 



]\Ir. (*lark : How will we ever know ? Take your brook trout 

 streams in Michigan today that were ])lanted before they were 

 depleted, how do you know that your ln"ook trout lived there? 



Dr. Parker: Because you have ])ut the l)rook trout where 

 there was none and they have grown. 



Mr. CUark : Xo, no, but take the natural streams where there 

 are plenty of trout. 



Dr. Parker : There are plenty there today. 



Mr. Clark: But according to your argument I might just as

 in those streams do not live. 



Dr. Parker: You do not know whether they live or not. 



Mr. Clark : Xo.

 — T lieartily Ix'lieve in the commission, and my suggestion as to 

 the ])lanting in T^ake Ontario there in that way is simply to prove 

 if you can the value of planting in large numbers, stocking a lake 

 like Ontario. It is only a suggestion. 



Mr. Clark : That is just the point I am arguing that the 

 vast quantities of whitefish that have been planted in Detroit 

 River and Lake Erie must make the increase, for we certainly 

 have an increase there. 



Di'. Parker: But you assume that this increase is due to the 

 fish you ])hint there. 



Mr. (Mark: I dislike to take up the time of the society but 

 this is a very important question and it must be discussed here. 

 The doctor says, "Take Lake Ontario" (which of course is a 

 good example; it is all right), but how will we prove anything 

 better in J^ake Ontario than we have already proven in Lake 

 Erii"? The only difference between the two lakes is this, that
