trefy. They are not infested with harmful
bacteria. You can never get tape-worm or any other parasitic trouble,
which occasionally follows the eating of infected food.

I am glad there are societies organized to propagate the nut. A
prominent concern of New York City is very active in promulgating the
value of the nut, and is encouraging the planting of nut trees.

Somebody has estimated that there are three million miles of country
roads, and that if nut trees were planted alongside these roads there
would be enough protein food for the entire population.

Nuts are rich in protein, lime, iron and vitamins.

Many dishes may be made from the nut which have the appearance and
flavoring of meat, without the objectionable effects of flesh diet.

Last year we imported twenty-five million pounds of almonds, forty
million pounds of Brazil nuts, eighteen million pounds of filberts, and
forty-four million pounds of walnuts,--about twenty million dollars
worth of these nuts were brought into the country.

This shows that there is some appreciation certainly of an article of
food which deserves to be even more commonly used than it is at present.

HARDINESS IN NUT TREES

_By C. A. Reed, U. S. Department of Agriculture_

Nut trees of most species commonly thrive at both latitudes and
altitudes much greater than the limits of regular or even frequent crop
production. This fact is seldom fully appreciated by prospective
planters, particularly in the North, who, not unnaturally, assume that
the presence of a group of vigorous appearing trees, or even of a single
tree, particularly in a fruitful year, is sufficient evidence of local
hardiness to justify commercial planting. However, practically all of
our native species of nut-bearing trees are indigenous well beyond the
range of regular crop production. This is made possible by occasional
seasons favorable to seed production which enable such species to
reproduce themselves. A crop once in a quarter century would be
sufficient for this purpose.

Taking the pecan as an illustration of how a species may be affected by
latitude, it has been found that, as the limits of hardiness are
approached, the ill effects on the species in approximate order are:

(1) reduction in size of nut, especially with oblong varieties
in length,
(2) increased proportion of faulty kernels,
(3) increased irregularity of crop,
(4) practical crop failure, and lastly
