In teaching Botany at the State University of Iowa the usual visual aids are regularly employed. These include lantern slides, motion pictures, charts, models and demonstration exhibits. The present note describes another useful visual aid in the teaching of Botany - the use of photo-enlargements. Teachers of other subjects should also find photo-enlargements of value in their classes. Photo-enlargements were used by Professor R. B. Wylie about twelve years ago to illustrate features of the brown algae studied by him in Alaska. These photographs were so well received by his classes and created so much interest that additional enlargements of other botanical subjects were made. Under the direction of Professor Wylie this nucleus of a few dozen photographs has been expanded into an assortment of several hundred carefully selected enlargements. Subject matter ranges from algae and fungi to typical examples of the higher plants and their parts. Included in the collection are scenes showing ecological situations, flower types, ferns and tree ferns, marine algae, tropical plants, lumber trees and photomicrographs of plant structures commonly studied. Enlargements of especially good line drawings, maps and charts are a useful part of the collection.
