APPLES 415 theory may be applied to the partial fecundation of the ovules by pollen in- jured in this manner as that injured by wet and cold Pollen grains may be entirely washed away during extremely wet weather or blown away during diT periods. High winds may waste the greater amount of pollen and may, during very hot weather, when the pistil is in a receptive condi- tion, so entirely dry up the fluids se- creted by the stigma as to make germi- nation impossible or even blow away what pollen is held by the stigma by reason of its roughened surface. Dust storms during the time when the pistil is receptive may make pollination im- possible from the fact that the papillose stigma catches dust particles which ab- sorb the juices there secreted and thus covers the stigma with a coating of very fine particles of dust firmly cemented to- gether by this sticky fluid. Several years ago Prof. W. J. Beal, of Michigan, published a series of articles on the classification of apples by their flowers. Pomologists gave little atten- tion to the work and nothing has been heard of it since. Orchardists need a more scientific and systematic classifica- tion than is offered by Thomas, Down- ing, and Warder, who base their classi- fication on season or color. In the study of the forms of blooms and the size and shape of the organs of the flowers, it was found that each variety possesses def- inite characteristics that might be used to distinguish, it from other varieties. These characteristics are often modifica- tions to insure pollination or to prevent self-fertili25ation, as in the case of Grimes Golden, in whicb the pistils recurve out- ward, as shown in Figure 2. In some of the flowers of this variety this char- acter is developed to
