FOURTH INTERNATIONAL FISHERY CONGRESS. 51 
shall give you a more or less rambling talk concerning some of the questions, at 
least, which are dealt with in their formal paper. 
[The paper by Professors Lefevre and Curtis will be found on pages 615-626.] 
Mr. Pau, Norts (Ohio). Will you kindly explain in reference to the col- 
ored buttons? 
The PRESIDENT. Mr. North asks a question. I learn that those which are 
discolored—are not uniform in color—are smoked by putting into nitrate of 
silver, and made into what is called the ‘‘smoky pearl.’’ There is a small 
demand for buttons of other colors, and those are produced by using aniline 
dyes, by which they can be made red, blue, and the different colors obtainable 
in the aniline dyes. 
The members may have noted the various exhibits that have been brought 
to the congress, with certain papers submitted in competition for prizes, and 
material that has been presented here by those who have been good enough to 
contribute to the programme. ‘This material has been arranged in front of the 
desk, and those who are interested in discussing it will kindly come to the desk 
at the conclusion of the sessions. And I shall ask those who have contributed 
the material to please install themselves as demonstrators of the respective 
exhibits. 
Will the honorable Mexican minister, Mr. José F. Godoy, please come to the 
platform? [Applause.] 
Mr. Gopoy. Mr. President and members of the Fourth International Fishery 
Congress, it is with great pleasure that I address you these few words to inform 
you that the Government I have the honor to represent here has felt great 
interest in, and attaches great importance to, the meeting of this congress. The 
discussions held at these sessions and the conclusions to be determined upon will 
no doubt greatly aid the Mexican Government in framing ampler regulations on 
the subject of fisheries, and I hope will also serve to establish measures looking 
to the preservation and increase of our fish industry. 
Permit me, in the name of President Porfirio Diaz, whose progressive and 
enlightened administration of affairs is well known to most of you, to present 
you his greetings and his best wishes for the success of your important labors. 
Permit me also to inform you that the Department of Promotion, which has the 
subject of fisheries under its charge in my country, and which at present is 
directed by Minister Olegario Molina, a most active and efficient cabinet officer, 
is looking to the results of the labors of this congress as a guide for its future 
work along the lines that may be pointed out in the deliberations of this inter- 
national gathering. 
To me, who have had the privilege of residing some time in Washington, the 
cordiality shown in the reception accorded to the members of this congress here 
has not been surprising. We all know the well-earned reputation for courtesy 
and hospitality which the inhabitants of Washington enjoy, and therefore it was
