Abstract

About seventy-live kinds of grasses and other forage plants were sown last spring. A considerable number of these were in one-eighth-acre plots, with a thin seeding of rye for protection. The rye proved to be the winter, instead of the spring variety, as was intended, and it grew so rank as to cover the ground and greatly injure the grasses. It was cut and removed July 7, but the weather following was so hot and dry that some of the kinds failed to recover. In addition to this, a severe attack of chinch bugs occurred in the* latter part of July and nearly destroyed many of the other kinds. Only the true grasses were attacked. The coarser kinds of these, such as Johnson grass, sorghum, teosinte, and the pearl and German millets, suffered least.
