GEOLOGICAL SOcIETY OF AMERICA, WINTER MEETING. 
This meeting was held at Rochester, at the University, under 
the presidency of C. D. Walcott, continuing three days. it 
was largely attended, and was marked by the presentation of 
thirty-six papers. The retiring address of the president was 
a sketch of the geology of America as it appears at the pres- 
ent time. This was not so much an examination of the science 
per se as an exposition of the ways and means of its prosecu- 
tion and progress, its status as an element in education and 
economics. The speaker also enumerated some of the outstand- 
ing problems that remain for the geologists of the twentieth 
century, springing mainly from the researches that have been 
entered upon in the nineteenth. 
The officers elected for 1902 are: President, N. H. Win- 
chell, First Vice-President, S. F. Emmons; second Vice-Pres- 
ident, J. C. Branner; Secretary, H. L. Fairchild; Treasurer, 
I. C. White; Editor, J. Stanley-Brown ; Librarian, H. P. Cush- 
ing; Councillors, C. W. Haves and J. P. Iddings. 
CLARENCE KING, first director of the United States Geo- 
logical Survey, well known as an expert mining geologist, died 
at Phoenix, Arizona, December 24.
