In A the scuteilum has degenerated, while in B it has remained ofdesirable shape. MORPHOLOGY OF THE BARLEY GRAIN. 29 power will be most likely to succeed if they are directed separatelytoward the four factors of efficiency, viz: (1) The shape of the grain,(2) the size of the scutellum, (3) the quality of the epithelial layer,and (4) the vital energy of the mature grain. All of these factors butfche last are varietal characters. Fortunately, varieties of extremeinferiority are for the most part already eliminated because of theirlow yield. The only decidedly inferior ones often met with in actualcultivation in America are certain Russian barleys with long, thingrains, a few winter varieties of similar character, and hooded sortsthat probably are abnormal in form because of the lack of the func-tional activity of the beard.
