"Querist." It is not necessary to cross or hybridize fruits in order to get new varieties. There is every reason to believe that though a flower was fertilized by its own pollen, there would be some variation among the seedlings. So far as we can judge, variation seems to be a part of the nature of things. The progeny will of course vary more from the parent form when fertilization is brought about through the agency of some very different variety. Variation is no proof of crossing by another variety, or hybridization through another species.
