DEPARTMENTS OF INSTRUCTION

Abbreviations used in the announcement of courses:

Yr—a continuous course extending through two semesters
I—course given during the first semester

II—course given during the second semester

I, Il—semester course given each semester

cr—number of credit hours per semester

*_to be arranged

Courses numbered from 1 through 100 are open for credit to undergrad-
uates only; from 101 to 199 to both undergraduates and graduates; over
200 to graduates only, or very exceptionally to advanced undergraduates.

The unit of reckoning the credit is one hour of classroom work per
week. Two hours of drawing, laboratory, field, or shop work (which re-
quire little outside preparation) count as one hour of classroom work.
