The variable growth of these trees proves that the first care in making a planting of walnut for timber should be to plant in good soil, deep and well drained. Bottom land, even some that is occasionally overflown with flood-water, and therefore not the best wheat land, should be excellent for Eastern Black walnuts if the drainage is good. Rule two:--Select your seed or seedlings from large, straight-growing, healthy parents. This rule needs explanation. In last October's NUTSHELL, an organ of the Northern Nut Growers' Association, Spencer Chase, its editor, called attention to a showing of Carpathian Persian walnuts by Mr. H. F. Stoke which illustrated what was called "the variability of seedling trees." The progenitor of these seedlings was a Lancaster Carpathian Persian walnut tree. Differences in size, appearance and quality of nuts from these seedlings were said to have been remarkable. Such differences, we know, are greater with some species than with others. A variable ancestry often results in a variable progeny. On the other hand, I know that my Eastern American black walnuts do tend to reproduce the characteristics of their parents. I have long rows of seedling trees, all from one parent tree, standing alongside long rows of seedlings from another parent. The similarity of the tree growth and nut production of the trees in their own rows, and their contrast in growth of trees and nuts to those in adjoining rows is striking and to me conclusive. A photograph taken by Dr. O. D. Diller, of Ohio State University, in 1946, shows trees in a right-hand row grown from seed of a tree on the Kinsey farm, while on the left are seedlings of a tree on the McCoy farm. The circumference of trunks of Kinsey seedlings averages more than twice that of McCoy trees. Same soil, same age (11 years), same treatment. Those same trees, now 17 years old, still show these striking characteristics. It is true that each tree in a row of seedlings is an individual in its own right. No others are exactly like it. Nevertheless, the family resemblances in that row are very like those in human families. They are especially noticeable in the nuts--with, for example, rough shells in one row and smooth shells in another; mainly large nuts in one and mainly small nuts in an adjoining family. Also, some rows have mostly straight-growing trees, others are predominantly branchy, like the Thomas. It should be said in this connection that practically all of the parent trees of these seedlings stood in isolated positions and little subject to pollination from other trees. So much for the Eastern Black walnut's evidence of hereditary influence. So, let us take inventory.
