Abstract
"Our Trees" by Professor H. S. Conard, Grinnell College, was used in the Mason City junior college biology in its first tree study of that city with its surrounding area. In the laboratory class study of the early fall, students were directed in the use of the "key." Later each one was responsible for the study of trees on his home lot, or an equivalent territory, collecting, pressing, mounting, labeling, and giving tree locations. Next, each student mapped his home block, adding to the leaf collections, and tree locations. Material was thus collected not only from Mason City hut from surrounding home towns of students in several years' biology classes.
