stops he expects to spend five or six weeks in camp, probably 
at the south end of Melville bay. The party will consist of 
one paleontologist, a student of stratigraphic geology, a photo- 
grapher, a civil engineer, and one other. They intend not 
only to study the glacial movements, etc., but also the general 
geolog3^ Arrangements will also be made to collect plants 
and animals. 
Ala^an Gold Fields. Mk. J. Edwakd Spurr has been sent 
to Alaska by the U. S. Geological Survey to investigate the 
gold field, especially those of Forty Mile creek. He is accom-

cross Chilkoot pass, at the head of Lynn canal, to the waters 
which flow into the Yukon and will descend by canoe to Forty 
Mile creek. They expect to spend a year and a half in Alaska,

Bryn Mawr College. Dr. E. D. Cope lectured May 14th 
to the students of geology on the argument for organic evolu- 
tion derived from the paleontological record. The work of the 
year closes with two excursions: an excursion into New Jer- 
sey where the gravels of the Pensauken and Jamesburg, the 
Raritan clays and clay marls of the Cretaceous series, and 
the Fish House clays were examined and fossils collected. 
This excursion was in charge of Dr. Wm. B. Clark. A second 
excursion is to be taken to Neversink and Penn mountains. 
This trip will afford opportunities to study Pre-Cambrian, 
Cambrian, Silurian and Triassic formations.
