THE author of "Orchard Grass" in August number of the Scientific Farmer may be glad to know that at least one agricultural college has for five years past had from fifty to one hundred and fifty species of grasses and forage plants, all in plots and labelled. A few farmers have studied them with great interest, and many of our students. Most of our visitors are bewildered among so many varieties, and give little attention to them, unless they are accompanied by a guide who knows about them, and remarks on their points of interest. W. J. BEAL, Professor of Botany and Horticulture. AGRICULTURAL COLLEGE, Lansing, Mich., Aug. 2, 1878.
