interests of the science. As an earnest of this wider effort 

 several eminent geologists, representing some of the leading 

 universities of this country, and some of the great geological 

 organizations of Europe, have kindly consented to act as associ- 

 ate editors. T. C. C. 



Upon invitation of the World's Congress Auxiliary of the 

 World's Columbian Exposition committees were appointed by 

 the several sections of the American Association for the Ad- 

 vancement of Science at its Rochester meeting to cooperate with 

 it in completing the organization of scientific congresses to be 

 held at Chicago in connection with the forthcoming World's 

 Fair. The committee appointed by the geological and geo- 

 graphical section consisted of Thomas C. Charriberlin, John C. 

 Branner, Grove K. Gilbert, W. J. McGee, RoUin D. Salisbury, 

 Eugene A. Smith, Charles D. Walcott, J. F. Whiteaves, Geo. H. 

 Williams, H. S. Williams and N. H. Winchell. 



It has been arranged that this committee should undertake 

 the work of preparing the scientific program for the Geological 

 Congress. The committee have prepared a provisional schedule 

 of topics, which they have submitted to the Advisory Council 

 for revision. It has seemed to the committee that all contri- 

 butions should be such as to have an international interest. 

 Preferably, they should be subjects that can only be treated most 

 advantageously in such a congress, especially those that involve 

 the bringing together of data from different lands for comparison. 

 The committee suggest the organization of the subjects under 

 the following general classes : 



First. Such as shall show the present state of geological 

 progress. It is believed that this can best be done by an exhi- 

 bition of geological maps which shall show the latest and best 

 results of official and other surveys. As such maps will be pre- 

 pared, it is hoped, for the World's Fair, duplicates can be made 

 at a slight expense for the use of the Congress. It is hoped 

 that each country that has made any notable progress in map-
