Institute, the Syracuse University, the University Convocation at 
Albany, N. Y., and some places in Michigan. 
At the Cleveland meeting of the American Association for the 
Advancement of Science he gave orally a statement before 
Section E. of some ‘‘Systematic results of a field study of the 
Archean rocks of the Northwest.” At a meeting of geologists 
for the organization of the Geological Society of America he was 
the chairman, and he also presided over the ‘organizing comumit- 
tee,” both then and subsequently at the meetings at Ithaca, and 
was continued as chairman of the same committee for the pur- 
pose of preparing the permanent constitution and perfecting the 
organization. 
A series of papers which he began in the AMERICAN GEOLOGIST 
on ‘Geology as a means of culture” were amplified and extended 
into a small volume which was concluded in November, This 
little work, entitled «‘Shall we teach Geology?” is intended to 
show that geology is adapted to younger pupils than generally are 
allowed to study it. Showing that it has those educational qual- 
ities that make it worthy of the highest esteem in a school currie- 
ulum, and that it is the result of a traditional preoccupancy of 
the field by other branches, that it is not admitted into the grades 
that precede the college course, he calls attention to the obstacles 
that lie in the way of a reform. The language is vigorous and 
direct, and the work has already produced a reflective reconsid- 
eration of school courses in several important educational centres. 
188. In pursuance of his Archean studies he engaged in a 
review of American opinion on the Presilurian rocks, and com- 
municated his results to the eighteenth report of the Minnesota 
survey. This review absorbed a vast amount of time and patient 
research. — [It is characterized by the fairness exhibited in the con- 
densed statements of results and opinions of earlier geologists. 
and it forms a useful and very valuable compend for reference. 
At Toronto he presented further results of his work in northern 
Minnesota. At this place the revised constitution of the Geologi- 
cal Society of America was reported and finally approved. He 
had seen the whole history of this enterprise from the time it took 
some definite shape at Cleveland, O., till it had its first public 
meeting for the reading of papers, at Toronto, and had nursed it 
faithfully. Tle was gratified now to know that it had acquired 
the semblance as well as the substance of a healthful organization,
