the former consisting of granites, gneisses, nepheline syenytes, 
quartzytes and slates, and the latter of Potsdam sandstone. 
The district is crossed by the boundary of the driftless area 
and Dv. Weidman has been able to differentiate several drift 
deposits lying outside of, and earlier than, the terminal mor- 
aine of late Wisconsin age. It is hoped that a report on this 
district in the north central part of the state, to be issued as a 
bulletin of the Survey, will be ready within a year. In the 
meantime a report on the soils of the district is being pre- 
pared for the Annual Report (for 1902) of the State Board of 
Agriculture. 
Dr. E. R. Buckley, now state geologist of Missouri, be- 
gan the preparation of a report on the road materials of Wis- 
consin while connected with the Wisconsin Survey, and it is 
expected that this report will be issued shortly. 
Professor N. M. Fenniman, of the University of Colorado, 
has prepared a report on the lakes of Wisconsin and their phys- 
iographic features, which is now in press. 
Professor U. S. Grant, of Northwestern University, is en- 
gaged in a study of the lead and zinc deposits of the south- 
western ]5art of the state, where there is a revival of mining 
interest. A preliminary report on these deposits will be pre- 
pared during the coming fall and winter. 
CoLUMLUA Univers[ty Xote.s : Professor J. F. Kemp 
left immediately after commencement for Wyoming, and 
passed a week in the study of the Rambler Copper mine and vi- 
cinity under the direction of Dr. David T. Day of the U. S. 
Geological Survey. The occurrence of the platinum group of 
metals with the copper lends special interest to the mine. Sub- 
sequently, in company with professor Wilbur C. Knight of 
the University of Wyoming, trips were made to the titaniferous 
magnetite at Iron ATountain and into the Leucite hills. Pro- 
fessors Knight and Kemp plan a joint paper upon the latter, 
many new data having befen accumulated regarding the struc- 
tural geology of the Leucite hills. 
The regular work of the second session in field geology 
for students in the Columbia School of Mines was conducted 
last year at Marquette, Michigan, by professor Grabau, 
owing to the illness of professor Kemp. This year 
it was given by professor Kemp at Bingham Canyon, 
Utah, during the week beginning July 13. A geologic map of 
the region around the principal mines was prepared by a class 
of fifteen, and observations were also made underground. In 
connection with this each pair of students will make a petro- 
graphical and chemical examination of the different rocks and 
ores found in the field. Every courtesy was extended to the 
party by the officials of the United States Mining Company, 
where headquarters were established, and by others in the 
camp.
