“I first began raising _Prunus maritima_ about 1887—twenty-two years ago—collecting myself and having specimens sent me all the way from the coast of Labrador to South Carolina, the finest of which were obtained from the eastern coast of Massachusetts. Among the seedlings, of which I raised and fruited several hundred thousands, were yellow, red, purple and almost black ones, early and late, round, oval, oblate and flattened, with big stones and little stones, free stone and cling stone, and much variety in productiveness and growth of the young bushes, but _not one of them_ the first two or three generations were very much increased in size—probably the largest being about the size of a cranberry or a small hazelnut—and none of them of very exceptional quality, though their habit of blooming late was a tremendous advantage, as they invariably escaped our spring frosts. This, with their unusual hardiness induced me to continue experimenting with them. Finally after some ten years I obtained a very delicious variety, about an inch in length and three-quarters of an inch in diameter, tree much increased in size, larger foliage and more productive and producing enormous quantities of most delicious fruit. From this I raised a great many thousand, almost as good and a few of them even _better_, several hundred of which have been selected and are now bearing on my Sebastopol place. Some of these improved seedling trees grow five to ten times as large as the ordinary Maritima, with larger leaves and in every possible way improved. My greatest success with this species (and one of the most striking occurrences in my work with plums) was produced by pollinating one of the somewhat improved Maritimas with _Prunus triflora_. “The very first generation, a plum was produced which is an astonishing grower for a Maritima—almost equal to the Triflora, with large, broad glossy foliage of almost the exact shape of the Maritima, Maritima blossoms, and fruit weighing nearly one-quarter of a pound each, with an improved superior Maritima flavor, Maritima pit in form, but enlarged. The most singular peculiarity of this plum, which is so enormous, is that the trees commence to bloom about with the Triflora and bloom and bear fruit all summer, so that blossoms, young fruit and the enormous deep red ripening fruit can be seen on the trees at the same time.” =21.= =PRUNUS GRAVESII= Small =1.= Small _Torrey Bot.
