filled nut. Trees growing in a crowded position, or on hard, dry
ground, seldom ever have all the moisture they need to produce a good
crop of well filled nuts. This has been plainly demonstrated with my own
and my neighbors' trees in the past few years.

The weather of the previous season also may have much to do with the
crop the following season, especially with trees growing under adverse
conditions. These conditions can often be largely overcome by the owner,
with fertilizers and cultivation.

In planting a tree be sure to give it plenty of space. If the soil is
lacking in plant food feed the tree, remembering it can draw food only
from a given space. No one would expect to grow the same farm crop on a
plot of ground for many years without fertilizer. Prepare to conserve
moisture for the hot, dry season either by cultivation or mulching. One
of the thriftiest best bearing nut tree plantings I know of is on very
sharp, hilly clay ground in Rockport, but the owner fertilizes these
trees annually and gives splendid cultivation.

A non-bearing nut tree is no better than any other kind of a tree, so it
is not a question of how many nut trees you have, but how many good
bearing nut trees you have. To get the best results provide your trees
with space, food and moisture.

Varieties of Nut Trees for the Northernmost Zone

_By_ C. A. REED, _Bureau of Plant Industry United States
Department of Agriculture_

The northernmost zone of the eastern part of the United States, within
which conditions appear at all encouraging for the planting of the
hardiest varieties of nut trees now available, may be outlined as
covering the milder portions of Massachusetts, Rhode Island,
Connecticut, New York, Michigan, Wisconsin, Minnesota and South Dakota.
Beyond the Canadian border this zone should perhaps include the fruit
belt of Ontario known as the "Niagara Peninsula," which skirts Lake
Ontario from the City of Hamilton to the Niagara river. No doubt it
should also include considerable Canadian territory immediately adjacent
to Lakes Erie and St. Clair, and north to the lower end of Lake Huron.

In each American state within this general zone there are numerous
localities to which several species of edible nuts are indigenous,
others where the butternut alone is found, and still others to which
none of the common kinds appear to be adapted. Climate and soil are both
limiting factors within this general section. No nut tree
