%he object of this investigation was to secure comparable data on the coumarin content and average percentage composition of several distinct types of sweet clover.. The plan als0 included a study of leaf percentages and a comparison ef the nutritive value of leaf and stalk. Determinations were made on three cuttings from the same variety test plats, one in the fall of the year that the clover was sown, and a first and second during the second season’s growth. A comparison was therefore possible on the basis of the ,three cuttings. The sweet clover samples .were taken from the plats at time of cutting for hay and the plants dried to constant weight in the laboratory. The leaves were removed from the stalks and the weights of leaf and stalk recorded. The material was then for.warded to Dr. Frank T. Shutt, Chief cf the DiviSion of Chemistry, Central Experimental Farm, Ottawa, through whose generous cooperation the chemical determinations were made.
