Tk) The American Geologist. January. i904. 
O. H. Hershey is operating a gold mine in Humboldt 
county, California, which promises well, and is incidentally 
studying the geology of the Klamath mountains. 
G. K. Gilbert and A. C. Lawson spent several weeks in 
the high Sierras, in California, last summer, primarily for re- 
creation, but with results of much geological interest. 
N. H. Darton, 01 the hydrographic division of the U. S. 
Geological Survey, has recently gone to Phoenix, Arizona, to 
direct investigations in artesian water supply at that place. 
Geo. D. Lauderback, of the University of Nevada, has 
leave of absence for a year, and is studying the crystalline 
schists of California, as a scholar of the Carnegie Institute. 
R. A. Daly, of the Canadian Geological Survey is engaged 
to give a course of lectures on physical geography at the Sum- 
mer School of the University of California at Berkeley, next 
summer. 
Mr. Gilbert van Ingen, late of the New York geological 
survey, has been appointed assistant in geology and curator of 
invertebrate paleontology at Princeton University, successor 
to Dr. Ortmann. 
Mr. H. V. Winchell gave an interesting description, with 
illustrations, of his last summer trip to the Copper River dis- 
trict, Alaska, at the November meeting of the ^Montana So- 
ciety of Engineers. 
Dr. J. C. Branner, \^ice-President and Professor of Geol- 
ogy at Leland Stanford Junior University, will leave for Eur- 
ope in the early part of January on his sabbatical leave of ab- 
sence from his university duties. Later on in the year he may

Dr. Geo. E. Ladd, director of the School of !Mines at 
Rolla, Mo., has recently been appointed as Superintendent of

chusett's display of structural and ornamental stone at Chi- 
cago Columbian Exposition. 
Remains of a large mastodox were discovered recently 
in the village of Belvidere, N. Y. They were unearthed by Dr. 
James Johnson of Bradford and Mr. Alban Stewart of the 
Smithsonian Listitution. The remains consist of three ribs and 
four vertebrae, each of the latter being six inches in width, in- 
dicating a very large individual. 
The Paleontological Department of the Massachusetts 
Institute of Technology was fortunate last year in having do- 
nated to it by the different students of the Institute much ex- 
cellent working material. The largest gift, a collection of Si- 
lurian and Devonian fossils from Kentucky and Indiana, was 
that of Mr. Eugene Burton of Louisville, Ky.
