These trees are about 60 years old and were planted by I. M. Johns, who took the donation claim two miles southeast of McMinnville, about 1844, now the Derr farm. The trunk of the largest one on the right is 10 feet in circumference, and is probably the largest English walnut tree in Oregon. They have some nuts every year, but are shy bearers, due no doubt to lack of proper pollination. The nut is not large, but is full of good meat and resembles the Parry. The trees are about two hundred yards from the Yamhill river, are hale and hearty and seem good for a few centuries. In fact, all of the seedlings examined in this county are healthy and vigorous. There are half a dozen or more walnut trees growing in the woods and about the garden of Mr. J. T. Jones, seven miles west of McMinnville, which are a valuable study to the walnut grower. They are seedlings from the Casey tree, and they all bear full crops every year. The largest is 21 inches in diameter. One of them has a much larger and finer nut than that grown on the Casey tree. Hardpan is reached about 18 inches below the surface, which would indicate that no tap root were needed were it not for the fact that a tiny brook runs down through the garden not far from the trees. Following is the testimony of Col. Henry E. Dosch, taken from "Better Fruit" of August, 1908: "It is over twenty years since I first experimented with nut culture, more especially English, or, more properly speaking, French walnut culture, and by persistent effort in keeping this matter before the horticulturists am more than gratified to know that this important industry is at last receiving the attention it deserves; and a few who took my advice in the beginning and planted on a commercial basis are now reaping the benefit, as their products command the highest price in the market. "First generation nuts are produced on original trees, or on trees grafted from the original trees. Those nuts when planted produce second generation trees, and the nuts from these second generation trees are a little larger than the original or first generation, which is due to the peculiar soil and climatic conditions of the Pacific Northwest, so well adapted to nut culture. Trees grown from second generation nuts retrograde very rapidly, producing nuts not half so large as even the first generation trees, and finally running out altogether. Hence it is very essential that we plant nuts from the original trees, or trees grown from the original nuts or grafted from the original trees."
