A correspondent of the Petaluma Courier says: - "The best kinds for pitting are the Columbia, Gross Prune and Washington; for prunes, the Petite Prune d'Agen, and the Yellow Egg for canning. Almost any of our soils are good for growing plums, but a clay sub-soil is best. But whatever soil you use, it should be under-drained, and well sheltered from the winds by eucalyptus and Monterey cypress trees. I think the plum stock is the best now for profit. Twenty-five acres in plums will make a man a nice income in a few years. I have in my orchard two acres and a half in plums, and they pay me on an average $500 a year."
