GEOLOGY / 183

must have a baccalaureate degree with a major in geology or a related field.
A course in field methods or a summer field course is recommended. Defici-
encies in undergraduate work in geology can be corrected concurrently with
registration in graduate-level courses.
 The Master of Science degree requires a thesis. The degree Master of
Science in Teaching is offered with specialization in geology. Candidates for
these degrees are advised to plan their work to secure a firm foundation in
geology, mathematics, and chemistry, physics, or biology rather than to spe-
cialize too narrowly.
