While it is generally found that seedling trees properly treated come into bearing the eighth year, this crop is usually light, doubling each successive season for seven or eight years. From then on there is a steady increase in crop and hardiness for many years. Often trees in Oregon bear in their sixth year; while there are instances on record of trees set out in February bearing the following autumn. This is no criterion, however, merely an instance illustrating the unusual richness of Oregon soil, and its perfect adaptability to walnut culture.

Thirty-five acres on the Prince place yielded at twelve years, twelve tons of fine nuts, which were sold at 18 and 20 cents a pound, two cents above the market price, making an average of $125 per acre. Another grove of two acres yielded in their ninth year two tons, or a ton to the acre, netting the owner $360 an acre.

Mr. A. A. Quarnberg's eleven-year-old trees averaged twenty-five pounds each. Mr. Henry J. Biddle's ten and twelve-year-old trees averaged thirty pounds each. One hundred fifty dollars an acre from twelve-year-old trees is a conservative estimate, though some groves not cultivated may fall under that figure, while others in a high state of cultivation will almost double it.
