is a practice
which it would seem could well be introduced to good advantage in the
eastern states.

Among the ornamentals, it is difficult to imagine a species which could
more effectively be used than the pecan. The picture before you was
taken of a comparatively young tree perhaps 30 or 40 years old on the
home grounds of a private citizen near Easton, Maryland at practically
our own latitude. It is a most beautiful tree.

Rightly used, the black walnut is also one of our most effective species
in the landscape. The picture before you is of a tree 51 years old. It
stands in front of the home residence of a sister to United States
Senator Charles L. McNary of Salem, Oregon. When photographed, this tree
measured 10 feet, 6 inches in girth at breast height. It would be hard
to imagine a more noble and graceful nut.

Along the roadways of California, we not uncommonly find the native
black walnut used as an avenue tree. It is very refreshing and cooling
on a hot day to drive under trees of the sort illustrated in the picture
before you. This avenue of trees is along the Lincoln Highway less than
a mile west of the University grounds at Davis.

THE PRESIDENT: The next speaker on the program will be presented by Dr.
Morris.

DR. MORRIS: They say that a biographer unconsciously writes his
autobiography. That is not tautology. Some one writing of the late Frank
N. Mayer said: "The plant hunter and explorer is the unsung Columbus of
horticulture." Our next speaker was the one who wrote that in Mr.
Meyer's biography. We all recognize it as autobiography. Emerson tells
us that every successful institution is the lengthened shadow of one
man. There were heroes before Agamemnon and botanists before Dr.
Fairchild, but with the beginning of the new century there came into
existence the development of a new idea, that of exploration in foreign
countries for the purpose of bringing to us their valuable plant
products. It was one of those things which we may say makes the whole
world kin because the economists tell us that basically the food supply
is fundamental to all subsequent human activities. Dr. Fairchild
organized the machinery of exploration for purposes of introduction into
this country of valuable plants from foreign lands. There is perhaps at
the present time no one who serves better as peace maker than does the
one who gives the world more food. From the economist's standpo
