126 The AmericMi Geologist. February, isoo 
The appearance of this volume marks an epoch in the geological 
work of the Alichigan survey, as well as in the progressive investiga- 
tion of the Keweenawan formation in general, and is highly creditable 
to all parties concerned. The Michigan Board of Geological Survey 
has not been one of the most energetic in promoting the enterprise 
for which it stands responsible in the state of Michigan, and has al- 
lowed much time and numerous opportunities to pass unimproved. 
B}^ issuing a few more such publications, however, it would recover 
the esteem and receive the thanks of the geologists of the country.
