A World's Congress of Geologists will be held in Chicago, 
in the summer of 1893, in connection with the World's Colum- 
bian Exposition. 
The excellent opportunity oflfered by this exposition for com- 
parative studies of the mineral resources of the various countries 
of the globe, cannot fail to act as an inducement for geologists 
to assemble on this occasion. It is also announced that many 
States in the Union, as well as countries in other parts of the 
world, have made liberal appropriations for their geological 
exhibits at the Columbian Exposition; and the exposition 
as a whole will surely attract great numbers of scientific vis- 
itors. 
The Congress will be held under the auspices of the AYorld's 
Congress Auxiliary of the AYorld's Columbian Exposition, which 
organization is recognized and supported by the United States' 
government as one of a series of congresses in the course of the 
exposition season, all intended to show the moral, social and in- 
tellectual advancement of the world at the present time. 
The American Association for the Advancement of Science, on 
its list annual meeting, recently (Aug. 16th-22d) held in Roch- 
ester, N. Y. , adopted resolutions cordially endorsing the con- 
gresses on the various branches of science within the scope of 
said association, and requested its various sections to appoint 
committees to cooperate with the respective local committees. 
Section E. (geology) acting upon this request, appointed a com- 
mittee of the following geologists, viz.: Thomas C. Chamberlin 
(chairman), John C. Branner, Grove K. Gilbert, W J McGee, 
Rollin D. Salisbury, Eugene A. Smith, Charles D. Walcott, J. F. 
Whiteaves, Geo. H. Williams, H. L. Williams and N. H. AYin- 
chell. The local committee consists of Josua Lindahl (chairman), 
Edmund Andrews (v. chairman), Victor C. Alderson, W. R. 
Head, Oliver Marcy and Charles W. Rolfe. 
The Directory will provide suitable places for meeting, and will 
extend to scientists in attendance all conveniences and courtesies 
consistent with the aims of the Auxiliary. 
It is expected that arrangements will be made to secure the pub- 
lication, in extcnso, of the proceedings of the various congresses 
and the important papers to be presented at their sessions. These 
publications will be a memorial of the civilization of the Nine- 
teenth Century. 
AYe hope in the next number of the Geologist to communi- 
cate the,exact date of the opening of the Geological Congress. 
All communications should, until further notice, be addressed to 
Dr. Josua Lindahl, Geologist, Springfield, Illinois. 
Dr. I. C. AYhite has severed his connection with the West 
Virginia University, Prof. S. B. Brown, his* late assistant, suc- 
ceeding him in the chair of geology. Dr. AYhite will liereafter 
devote his attention exclusively to his professional work in coal.
