alling for more specialization, the
professional geologist is now being called in to a larger extent than
formerly. A logical trend also is the acquirement of more engineering
training on the part of the geologist, for the purpose of pursuing these
applications of his science.

CHAPTER XXI

THE TRAINING, OPPORTUNITIES, AND ETHICS OF THE ECONOMIC GEOLOGIST

Economic geology is now an established and well-recognized profession,
but there is yet nothing approaching a standardized course of study
leading to a degree in economic geology. There are as many different
kinds of training as there are institutions in which geology is taught.
Within an institution, also, it is seldom that any two persons take
exactly the same groups of geologic studies. This situation allows wide
latitude of training to meet ever changing requirements, but in other
respects it is not so desirable.

PURE VERSUS APPLIED SCIENCE

In no institution are all the applied branches of geology taught. There
is constant pressure for the introduction of more applied courses; this
seems to be the tendency of the times. The economic geologist, fresh
from vivid experiences in his special field, is often insistent that a
new course be introduced to cover his particular specialty. Any attempt,
however, to put into a college course a considerable fraction of the
applied phases of geology would mean the crowding out of more essential
basic studies. To yield wholly to such pressure would in fact soon
develop an impossible situation; for, on the basis of time alone, it
would be quite impossible to give courses on all of the applied subjects
in a training period of reasonable length.

On the other hand, the failure to introduce a fair proportion of app
