CORRESPONDENCE. 
A Pkpi.y to some Statements in Professok Takk's "Lake Cayi ga 
a Rock Basin."* Under the title "Lake Cayuga a Rock Basin," Prof- 
Ralph S. Tarr, of the geological department of Cornel] University, pre- 
sented a paper before the Boston meeting of the Geological Society of 
America (December 29, 1893), which lias since been issued in its printed 
form. In this paper he has quoted from an early publication of mine, 
and. by the selection of a few sentences apart from their context, has 
placed a misconstruction upon my work which I am unwilling to let 
pass without correction. 
The field work upon which my little article "The Geology of Itasca, 
New York, and the Yicinity."f was based, was that of a college under- 
graduate, having been done during the winter and spring terms of 1874- 
75 in the preparation of a thesis for graduation at Cornell University. I 
do not offer this as any excuse whatever for the conclusions reached, for 
I am still willing to be judged by them, but to emphasize the fact that, 
after twenty years of progress in the study of glacial phenomena, it 
would, indeed, be surprising should different interpretations not be 
placed upon the same data. That my views, as then expressed, were in 
accord with "the modern school of glacial geologj',*' will, I think, be 
apparent to those who read understanding^ - what I said upon the sub- 
ject. 
My thesis opened witli a general account of the topography of the 
region about Ithaca, incidentally mentioning Cayuga lake, but was 
mainh devoted to the consideration of "Special Features on Six Mile 
creek." That it was well thought of by the Faculty is attested by the 
award of the "President's First Prize in Geology." Later. I was re- 
quested to select from il a portion of general interest for presentation to 
the public on Commencement day, and this paper, in substance, was 
sent to the American Naturalist, appearing in the issue of that magazine
