FOURTH INTERNATIONAL FISHERY CONGRESS. . 45 
intend merely giving the main points of my paper, which is rather in the way of 
suggestion than of a set treatise or essay. 
[This paper was then read in abstract.] 
The PRESIDENT. Members of the congress, this interesting paper is open 
for discussion. I think that we all feel that the ground has been pretty well 
covered by Professor Prince. The fact that the paper is not being discussed 
does not indicate that we have not been very much interested in and instructed 
by listening to it. 
May I ask if the secretary-general has the paper by Mr. Franz von Pirko, 
“The Naturalization of American Fishes in Austrian Waters?” 
The SECRETARY-GENERAL. Mr. von Pirko has been obliged to leave the 
city, and I shall not read his paper, but shall simply state that he has gone to 
the trouble to write it in excellent English and to give us for distribution 
copies of it printed in German. These will be distributed to those who 
desire them, and the paper will simply be read by title and published in full in 
the proceedings. [See pages 977—982.] 
The PRESIDENT. I am instructed to state that all of the papers that have 
been submitted to the conference and reports of the discussions taken by the 
stenographer will be published by the United States Government and distributed. 
We now come to the last subject on the programme for this afternoon, the 
dogfish question, to be opened by Professor Field, and to be discussed by Messrs. 
Fryer, Nordqvist, Gill, Whitman, Prince, and others. 
Prof. Irvinc A. FreLp. Mr. President and gentlemen, I am asked to start 
the discussion this afternoon on the dogfish question. Before entering on that, 
I wish to say a few words on the mussel. The title of the paper which was 
called for yesterday and the day before is, ‘‘Sea Mussels and Dogfish as Food.”’ 
I have here a few samples of preserved mussels and dogfish, which I shall pass 
around. 
[Professor Field’s paper appears on pages 241-248, and following it is the 
discussion, which was participated in by the president, Dr. Oscar Nordqvist, Dr. 
Theodore Gill, Mr. Charles E. Fryer, Mr. T. E. Libby, Mr. Charles G. Atkins, 
Mr. John J. Pew, Prof. E. E. Prince, Dr. George W. Field, Mr. Walter E. 
Hathaway, Mr. E. C. Whitman, and Prof. Irving A. Field.] 
The PRESIDENT. If there are no more contributors to this discussion, a 
motion to adjourn will be put. 
The SECRETARY-GENERAL. Before the motion is put, I would like to sug- 
gest that, in view of the lateness of the hour, the committee on resolutions do 
not meet this evening, but instead at 9 o’clock to-morrow forenoon, in this 
room. 
Thereupon, at 6 o’clock p. m., the congress adjourned until 9.30 o’clock 
Friday morning.
