s might be the alternate planting of quick-growing species which
would furnish shade in a minimum length of time, and which could be cut
for pulp or other purposes by the time the nut trees reach maturity.

A practical objection to highway planting of nut trees is that unless
cared for, such trees are in danger of becoming breeding places for
diseases and insect pests which would quickly spread to nearby orchards.
However, such planting in numbers too small to be worth caring for is
not to be considered. Already the country is agreed that the maintaining
of the middle of the road in such condition that it can render maximum
service is a paying investment. The suggestion here made is only as the
next step in highway investment. It is a proposition to make more
comfortable and attractive the present system of roadways, and at the
same time to help develop new varieties of nut trees for orchard
planting. Unless such new varieties are soon to become available, a
large part of the country will presently find itself dependent upon
outside sources for its principal substitute for meat and its main
supply of vegetable fats.

A little thought should be able to work out a sound program for the
planting of utility trees on practically every highway in this country.

Since this manuscript was completed, attention has been called to a
reference to a war use of the horse chestnut, which appears on page 18
of the July number of "My Garden," a monthly publication, with
headquarters at 6 Bouverie Street, Fleet Street, London. As the heading
"NEW USE FOR HORSE CHESTNUTS," and its sub-head "Cereal Saving," both
indicate it may be of interest to the American people, although the
production of horse chestnuts in this country is not large. The article
which is credited to The Times, is as follows: "An important war time
use has been found for horse chestnuts by the systematic collection and
transport of all the nuts that can be obtained to the centre where they
can be utilized. Up to the present time cereals have been necessary for
the production of an article of great importance in the prosecution of
the war. Under the direction of the Food (War) Committee of the Royal
Society, which acts for and in consultation with the Royal Commission on
Wheat Supplies, the Minister of Food, and the Minister of Munitions,
experiments have been carried out during the winter to find a substitute
for these cereals, and thus to set them free for food suppli
