Pears resulting from self-fertilization arevery uniform in shape. They differ from crossesnot only in size and shape, but also, in somecases, in time of ripening, and in flavour. 10. Among the crosses the differences wereslight or variable, so that the variations cannotbe ascribed with certainty to differences inpollen. 11. Self-fecundated Pears are deficient inseeds, and the seeds produced are usuallyabortive. The crosses are well supplied withsound seeds. 12. Even with those varieties which arecapable of self-fecundation the pollen of an-other variety is prepotent, and unless theentrance of foreign pollen is prevented thegreater number of fruits will be affected by it. 13.

Accompanying the report referred to areillustrations of Williams Bon Chretien (Bartlett)Pears, one fruit being the result of fertilizationwith its own pollen, and the other from fertiliz-ation (or pollination, which is the preferableterm) with pollen from Easter Beurre, the differ-ence in shape being conspicuous, and the latteris altogether a much better developed fruit thanthe former. Besides possessing a special scien-tific interest this subject is also of considerable practical importance, and it deserves more at-tention than has hitherto been accorded to it. When failure to fruit is due to early or toofrequent overcropping, to a natural weakness,or to some deficiency of essential substancesin the soil, liberal but judi
