but we must not quarrel with things that exist, but, if we can, 

 correct them. It is a very gratifying thing to know there are 

 two states that are working along these lines. Illinois has es- 

 tablished what is called a natural history observation station. It 

 is in the hands of a very capable man with able assistants, and 

 there is no question Imt good results will follow. 1 con- 

 gratulate Wisconsin upon having associated with its commission 

 a man who has not only the ability, but the inclination to follow- 

 out these investigations that will certainly result in benefit to fish 

 culture. These investigations may at present seem somewhat 

 remote, Ijut they are not so, and in order to get an intelligent 

 conception of the matter, the whole range of inquiry as it is re- 

 lated to the different forms in water, temperatures and all those 

 things that are naturally connected with it, these investigations 

 must be made in order that just conclusions may be drawn. 

 We will now listen to a paper by Professor Reighard. 



Professor Reighard : I hatl intended to present a review of 

 what has been accomplished in the scientific study of the fresh 

 waters, since the revival in that line of study; but when I came 

 to look into the matter more carefully I found there was so little 

 of it, and so much of that that was not of direct interest to prac- 

 tical fish culture, that I limited the paper to certain thou<jhts on 

 the recent developments in the study of fresh waters from a scien- 

 tific point of view.
