The giant prune is here shown three-quarters its natural size. A glance shows why it is regarded as a valuable fruit by plum growers in many regions. This plum has proved especially valuable for shipping and for canning. When placed in boiling water the skin immediately rolls away from the fruit, leaving the rich, honey-colored flesh ready for the can.
