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.
Today, I figure that the thousand well-grown trees in this planting are
each adding a dollar per year to the value of the 20 acres upon which
they stand. $1000 per year in all. This estimate, which of course seems
optimistic, is based upon the statement of a walnut tree buyer--a
sawmill man--who tells me that a well grown, deep-soil, 50-year-old
Eastern Black walnut tree should average about $50 in value. Thus far,
my 17-year-old youngsters, some of them nearly 3 feet in girth (9-1/2 to
11 or more inches in diameter at breast height) look promising.
In addition to the potential added value of $1000 per year, this 20
acres has produced about two tons of in-hull nuts from selected trees
only, in each of the past two years, (with more than that in prospect
this year), while the land beneath the trees grows good pasture and
helps to support a small herd of cattle and calves.
Once the trees were thoroughly established, the labor investment has
been very small. Nature, for the most part, has done her own pruning,
and has done it better than I deserve. Since the first half-dozen years,
there has been no cultivation. The trees have been practically
trouble-free. Winds have damaged a few and one wet spot has killed three
trees. There are a few black locust trees among the walnuts. I can see
no evidence that the walnuts have made either better or poorer growth
because of the proximity of these nitrogen storers. Perhaps the evidence
will show up later. We shall see.
The last item in this inventory, added value to the estate, is still
potential, but the potential is surprising. If my walnut timber buyer's
estimate i
