variety of the common wild blackberry, which was discovered by a
clergyman at the edge of the woods on the Kittatinny Mountains in New Jersey, has produced fruit under skilled cultivation that still remains the best of its class. When clusters of blossoms and fruit in various stages of green, red, and black hang on the same bush, few ornaments in Nature's garden are more decorative. Because bramble flowers show greater executive ability than the raspberries do, they flaunt much larger petals, and spread them out flat to attract insect workers as well as to make room for the stamens to spread away from the stigmas - an arrangement which gives freer access to the nectar secreted in a fleshy ring at the base. Heavy bumblebees, which require a firm support, naturally alight in the center, just as they do in the wild roses, and deposit on the early maturing stigmas some imported pollen. They may therefore be regarded as the truest benefactors, and it will be noticed that for their special benefit the nectar is rather deeply concealed, where short-tongued insects cannot rob them of it. Small bees, which come only to gather pollen from first the outer and then the inner rows of stamens, and a long list of other light-weight visitors, too often alight on the petals to effect cross-fertilization regularly, but they usually self-fertilize the blossoms. Competition between these flowers and the next is fierce, for their seasons overlap. The DEWBERRY or LOW RUNNING BLACKBERRY (R. Canadensis), that trails its woody stem by the dusty roadside, in dry fields, and on sterile, rocky hillsides, calls forth maledictions from the bare-footed farmer's boy, except during June and July, when its prickles are freely forgiven it in consideration of the |
