The courses in agricultural economics are intended to give the students
a knowledge of the economic principles which relate to the production and
marketing of farm products, and to the economic and social conditions of
the agricultural classes. As such it is a field of general interest to all
concerned with farmers and their welfare.

There are two methods of taking agricultural economics. First, it may
be taken as a joint major along with work in one or more other depart-
ments, economics being recognized as a phase of farming coordinate with
many other lines of inquiry; second, agricultural economics may be taken
as a full major by those who decide to make it a main line of study prepar-
atory to teaching, research, or work of an economic character. The major
consists of 15 credits, including the thesis.
