sent American Geology in the International Congress of Geolo- 
gists) held in Albany on April 6, there were present, Professor 
James Hall (President), Professors Hitchcock, Stevenson, Wil- 
liams, Winchell, Cook, Cope and Frazer (Secretary). Professors 
Emerson and Smock, Clarke, Dr. Rominger and Mr. Beecher

unanimous vote Mr. W. J. McGee was invited to take the place 
of Major Powell, who was prevented by sickness from attending. 
The Secretary announced that there had been forty-five sub- 
scribers for fifty copies of the geological map of Europe. 
A motion was adopted abolishing the Committee of the Whole 
and its officers, and entrusting the duty of preparing reports on 
the separate divisions of the geological column, to eight Report- 
ers, Who were thereupon unanimously elected (see card to Geol- 
ogists below). 
The following was adopted by the Committe: Kesolved, That 
we recommend to American geologists the acceptance of the con- 
clusions of the International Congress, said changes to be form- 
ulated at a subsequent meeting of the Committee; and it being 
understood that the Committee will present such additions as 
are deemed necessary by American geologists, to the Congress 
of London in 1888. 
2. International Congress of Geologists — American Com- 
mittee. Philadelphia, April 22, 1887.—At the recent meeting of 
‘the American Committee in Albany, “ Reporters” were elected, 
whose duty is to prepare reports on the several parts into which, 
for convenience, the geological column has been divided. The 
assignment is as follows: Quaternary, Recent, Archeology, 
Major Powell, D’r U. 8. G. 8., Washington, D. C.; Cainozoie 
(Marine), Professor E. A. Smith, State Geol. Univ. Ala., Tusca- 
loosa; Cainozoic (Interior), Professor E. D. Cope, 2102 Pine St.,

Rutgers Coll., New Brunswick, N. J.; Upper Paleozoic; Car- 
bonic, Professor J. J. Stevenson, Univ. City of New York, N. Y.; 
Devonie, Professor H. 8. Williams, Cornell Univ., Ithaca, N. Y.; 
Lower Paleozoic, Professor N. H. Winchell, St. Geol. Univ. of 
Minn., Minneapolis; Archean, Dr. Persifor Frazer; 201 South 5th 
st., Philadelphia, Pa. 
It is the duty of these Reporters to obtain, each for his own 
subject, as complete information as possible from American geolo- 
gists interested in it; but on account of the difficulty of ascer- 
taining the names of all who have information to impart on a 
particular topic, it will not be possible to address letters to more 
than a few of those who are known to have studied a subject. 
For this reason each of the undersigned appeals to aid his pro- 
fessional brethren for aid in preparing the report which is en- 
trusted to him. It is not possible that any single scheme will 
be approved by all geologists, and therefore it is the more nec- 
essary that there should be a fair statement of any opposing
