144 Thirty-fourth Annual Meeting. 
As the Department of Agriculture has begun the good work 
of protecting and conserving our game-birds and mammals, the 
question naturally arises: Why should not Federal protection 
be extended to our fishes in public waters? I can imagine no 
good reason why the United States Bureau of Fisheries should 
not take an active interest in preventing the pollution of public 
waters, and in protecting the fishes that inhabit them. In antic- 
ipation of the extensive irrigation projects contemplated by the 
general government in the western states, the influence and 
timely action of the bureau would prevent the almost total de- 
pletion of the streams of fish life which would otherwise surely 
follow. 
DISCUSSION. 
President: In the report of Dr. Henshall’s paper read ves- 
terday at the hatchery, Mr. Clark has discovered what he claims 
to be some inaccuracies, and he would like to state them and have 
them corrected, so as to have it go into the published proceed- 
ings all mght. 
Mr. Clark: It is unfortunate that the paper of Dr. Henshall 
on “Phe Protection of Fish in Inland Waters,” could not have 
been read in full before the meeting. It was read before the 
vathering down at the hatching station, when very few were 
present, and in fact I believe part of the paper was not read at 
all. Since that time | have had the privilege of reading his 
paper, and after going over it quite carefully, I think it worthy 
of very careful consideration. 
Dr. Henshall savs in his paper: “In Michigan, in each re- 
curring spring, the logs ploughed up the spawning beds of the 
eravling, destroying the ova almost entirely, for many seasons. 
And to this cause alone, is to be charged the almost total extine- 
tion of the grayling in Michigan waters, and not to over-fishing. 
Neither have they been driven out by the trout, as has been 
alleged. Before the era of logging, trout and grayling had ex- 
isted for all time.” I wish to call attention to the fact that in 
printing the paper that way without making any explanation, it 
would seem as though the Michigan and the United States Fish 
Commissions had practically nothing to do with these streams, 
so far as stocking is concerned. It is not a fact that the grayling
