cr\stalline rocks of the north-central part of the state. 
(3) Dr. U. S. Grant, assisted by Dr. C. P. Berkey, is to work 
on the copper-bearing rocks of Douglas and Bayfield 
counties. (4) Dr. W. H. Hobbs and C K. Leith will com- 
plete an investigation of the pre-Cambrian volcanics of the 
Fox River valley. A report on the building stones of the 
state, by Dr. Buckley, is nearly ready for distribution; and 
a report by Dr. Weidman, on certain of the pre-Cambrian

Prof. C. H. Hitchcock, who has been spending the year 
in travel, expects to reach home in time for the 51st meeting of 
the A. A. A. S., at Columbus, and to resume his duties at 
Dartmouth college upon the opening of the new year. Dur- 
ing September last he made a study of certain features of 
the Hawaiian islands. From there he went to Australia, 
making as close an examination of the general geology of 
the continent as time permitted. Later New Zealand was 
visited, for the purpose of investigating the glaciers and of 
searching for relics of former greater extension. In Febru- 
ary his return trip began, leading across Australia again, and 
to Honolulu. Since early in March Prof. Hitchcock has 
been studying in detail the volcanic action and vegetation 
of the Hawaiian islands. 
Prof. N. S. Shaler will continue this season studies 
which were begun in 1897 and 1898 upon the geology of the 
gold-bearing slates of Nova Scotia, and the auriferous gra- 
vels of portions of Montana.

Carnegie Museum at Pittsburg, Pa. He is now in the field 
in W)oming, beginning the collecting for the new museum.
