376 The American Geologist. June, i9o« 
in southern Norvva}' siiice the close of the Glacial Epoch," 
Dr. Brogger has determined the extent of the Scandinavian 
ice sheet, the level of the land during the Glacial epoch and 
the temperature of the Glacial climate, as well as the osci- 
lations in level and the climatic changes since that period. 
Both the facts themselves and the methods by which 
they have been obtained are, in a great part, new, and of the 
greatest interest. These lectures were illustrated by lan- 
tern slides and fossil material. 
The following are the names of some of the geologists 
in attendance upon the lectures: 
A. H. Brooks, U. S. Geological Survey; F. Bascom, Bryn Mawr Col- 
lege; W. B. Clark, Johns Hopkins University; Whitman Cross, U. S. 
Geological Survey; J. S. Diller, U. S. Geological Survey; B. K. Emer- 
son, Amherst College: S. F. Emmons, U. S. Geological Survey; Edw. 
H. Griffin, Johns Hopkins University; Arnold Hague, U. S. Geological 
Survey; J. A. Holmes, State Geologist, N. Carolina; H. M. Hard, Johns 
Hopkins Hospital; J. D. Irving, U. S. Geological Survey; Arthur Keith; 
U. S. Geological Survey; E. B. Matthews, Johns Hopkins University; 
F. B. Peck, Lafayette College; F. L. Ransome, U. S. Geological Survey; 
H. F. Reid, Johns Hopkins University; Ira Remsen, Johns Hopkins 
University; R. B. Rowe, Johns Hopkins University; F. C. Schrader, 
U.S. Geological Survey; G. O. Smith, U. S. Geological Survey; A. C. 
Spencer, U. S. Geological Survey; J. E. Spurr, U. S. Geological Survey; 
N. H. Stokes, U. S. Geological Survey; G. W. Stose, U. S. Geological 
Survey; H. W. Turner, U. S. Geological Survey; C. D. Walcott, U. S. 
Geological Survey; H. S. Washington, Locust, N. Jersey; Mrs. Geo. H. 
Williams, Baltimore; Bailey Willis, U. S. Geological Survey. 
A most interesting and profitable feature of this gather- 
ing of geologists was the excursions arranged by Dr. Wm. 
B. Clark in honor of Dr. Brogger. These excursions inclu- 
ded short trips into the country adjacent to Baltimore and 
two long trips. 
The state boat "Governor McLane" was put at the dis- 
posal of the geologists and April 28th, 29th and 30th were 
spent on the Chesapeake bay and the Patuxent river exam- 
ining the Cretaceous and Tertiar)' formations. At the close 
of the season of lectures a trip was made from Washington, 
on the private launch of the president of the Chesapeake 
and Ohio canal, up that canal by way of Point of Rocks and 
Harpers Ferry into the Central Appalachian district. From 
this point the party was transferred by special train to the
