The winds take the young shoot for a nucleus and pile their sands all up about it, yet may not quite cover the very tip, for there the varying draft whirls the topmost sands away again. The sand really helps. It mulches the young plant and protects it from the winter cold and the gales, from the summer heat and the drought. Each year the thus protected plant grows joyously more straight shoots, to be whelmed again almost to the tips by the sand, and so the merry war goes on till finally we have a dune twenty-five or thirty feet high, with the trunk and larger branches of a wild cherry tree for a core, its smooth, hard-packed surface wreathed with green leaves and often bearing rich, dark fruit for the delectation of all who pass.
