A Luscious Fruit
This shows a specimen of the Standard prune, natural size. This prune is so large that nine or ten of them weigh a pound. The stone is so relatively small that it represents only 3.5 percent of the total bulk. It is also free-stone-a very great merit, as every eater of prunes will admit. These massive prunes are often sold in the market as plums to be eaten fresh.
