40 BULLETIN OF THE BUREAU OF FISHERIES. 
(1887), 4,000 fry of the same species were liberated in the lake at Nikko, and 
recently, in 1907, 200,000 fry brought from America in the form of eggs were put 
into the same lake. 
Vice-President HoEK. We had better go on at once to the next paper. 
If I am reliably informed, we shall have considerable discussion on the whitefish 
production of the Great Lakes. May I ask whether Mr. Frank N. Clark, 
Superintendent of the Fisheries Station at Northville, Michigan, is present? 
Will you now give us the pleasure of hearing your paper, sir? 
Mr. FRANK N. CLARK. Mr. President, ladies, and gentlemen, having received 
a communication from the secretary-general of this congress requesting me to 
prepare something upon a subject which comprises the study and labor of the 
past forty years of my life, and realizing that the papers which would be sub- 
mitted at this meeting for your thought and consideration would be innumerable, 
I have concluded that a mere outline of my plan for the promotion of the white- 
fish industry of the Great Lakes is the most that would be proper for me to 
submit to you on this occasion. In preparing the following paper I was not 
unmindful of the desirability of eliminating, in so far as possible, complicated 
and tiresome matter. 
[Mr. Clark then read his paper, ‘‘A Plan for Promoting the Whitefish Produc- 
tion of the Great Lakes,’’ which appears on pages 635-642.] 
A MemsBeEr. There are two more papers on this subject. Each one advocates 
an open season during the spawning season of the whitefish, and each one 
proposes remedies very similar to those of Mr. Clark. I therefore move, sir, 
that before having any discussion on this paper the other papers be read. 
[The motion was duly seconded and carried.] 
Vice-President HorxK. I have the pleasure now to say that the paper of 
Mr. S. W. Downing, superintendent of the United States Fisheries Station at Put- 
in-Bay, Ohio, will be read by Mr. Titcomb. 
[Mr. Downing’s paper appears on pages 627-633. | 
Vice-President Horx. Professor Ward, will you be so kind as to read 
for us the paper of Mr. Paul Reighard of the University of Michigan, Ann Arbor, 
Mich., on this same subject? 
Prof. Henry B. Warp. I have, Mr. President and gentlemen, been re- 
quested to read the paper by Mr. Reighard on a plan to promote the whitefish 
production of the Great Lakes. It is my intention, even at the risk of doing 
the paper injustice, to present merely a few words of the introduction and the 
conclusions. 
[The paper of Mr. Reighard was then read in abstract, and appears in full 
on pages 643-684.| 
Vice-President HoEK. Gentlemen, we have had three papers on that inter- 
esting question, the promotion of the whitefish production of the Great Lakes, 
and it is understood that the discussion of the question shall take place in the 
afternoon; and I have now the pleasure of calling on Mr. J. W. Titcomb, the
