Pkogeess of Economic and Scientific Aghostologt

The science of agrostology^ strictly speaking, relates only to the true grasses, and an agrostologist is one who has made a special study of these plants; but in the present paper the term is used in a broad sense, and embraces not only the true grasses, but all other pasture and fodder plants. In this broad sense the subject becomes one of the greatest economic importance, in which every citizen of the United States is more or less directl^Mnterested ; but only its more salient features can be considered in this paper, many interesting minor facts being of necessity wholly omitted. In the present treatment of the subject it has been found convenient to divide it into two parts: First, economic, or applied, agrostology; second, scientific, or systematic, agrostology.
