“ A large number of the varieties of both the green-podded and the wax-podded beans are used almost exclusively as snap beans, to be eaten with the pod while tender. The various strains of the Black Wax are the most popular string beans. The pole or running beans are used either green or dried, and the Limas, both tall and dwarf, are well known for their superior flavor either as shelled or dry beans. The old-fashioned Cranberry or Horticultural Lima type (a pole form of Phaseolus vulgaris) is probably the best shell bean, but the trouble of poling makes it unpopular. ”
