During the winter of 1924-25 it was undertaken to count the trees within the city limits of Mt. Pleasant. The work was done by students of the department of Biology of Iowa Wesleyan College, who were trained in accurate tree identification before the work was begun. All trees over four inches in diameter at breast height were counted. The accuracy of the identification and count was safeguarded in every way possible.
