tute of Electrical Engineers, American Society of Naval Architecture and 

 Marine Engineers, American Academy of Political and Social Sciences, 

 and National Academy of Sciences. This program was distributed 

 throughout the 2 1 Republics from the office of the secretary general in the 

 Pan American Union. It was printed in English, Portuguese, and Span- 

 ish. Copies were sent to educational institutions, learned and scientific 

 societies, and individuals in the several countries. The cooperating 

 committees appointed at the request of the Government of the United 

 States by the Governments of the different Republics assisted likewise 

 in the distribution of this program. These committees, the members of 

 which may be found in the Final Act, pages 323-329, rendered further 

 most valuable assistance in securing proper representation of their respec- 

 tive countries at the congress by the appointment of delegates and in the 

 selection of writers of papers. They cooperated also with the executive 

 committee of the United States in maintaining the Pan American character 

 of the congress. 



This distinctive Pan American character was further greatly enhanced 

 through the special group conferences held at the time of the con- 

 gress by the dififerent sections and subsections. Special topics, 

 called Pan American themes, were chosen and submitted during the 

 latter part of the summer through official channels to the different 

 countries. In addition to the diplomatic representatives. Government 

 officials and cooperating committees, individuals in the different coun- 

 tries, to whom the executive committee now acknowledges gratefully 

 its indebtedness, assisted in the distribution of these themes. Papers 

 were presented by the leading specialists of the several Republics. On 

 account of the timely and scientific interest of the topics the papers 

 grouped around them were profitably discussed in stimulating conferences 

 by representatives from the larger part of the RepubUcs participating in 

 the congress. These Pan American themes may be found printed in the 

 report of the Final Act, English edition, pages 159-162.

 papers and members of committees were extended by the secretary
