The sharp edges of this leaf cut like a knife, often wounding animals. A large order of about 3SC0 species, many of which are very important to man. Among thetn are the wheat, oats, rye, corn, wild rice, sorghum, and sugar cane, the two latter being the sources of some of the sugar of com- merce. Many grasses, also, are important forage plants, among which may be named blue grass, timothy, brome grass, and red top. Some grasses are used in medicine. The Bamboo, native of the tropics, is valuable, being used not only for building purposes, but also in the manufacture of household furniture and in other ways. Very few of the grasses have deleterious properties. A few, such as sleepy grass and millet, the latter of which is injurious to horses, are known to be poisonous. Some grasses, because of their stiff awns, penetrate the skin and even perforate the intestines, inflicting dangerous wounds. Needle grass and squirrel tail grass, or wild barley, are known to inflict injuries by lodging between the teeth, thus causing pus infection. i.
