such pods are generally small as compared with those borne on
"female" trees in the same locality, and I have never observed a heavy
pod crop on any "male" tree. Grafted trees of Millwood and Calhoun
selections in Tennessee were observed to set pistillate flowers, but no
pods (or very few) matured on them unless there was a "male" tree in
flower within insect-flight distance from them. (At Auburn, Alabama,
there were wild honeylocusts, including "male" trees, within a half-mile
of the Hillculture planting of grafted honeylocusts when I saw it in
1943.)

I do not argue that no pollen is ever produced by Millwood or Calhoun
flowers some probably is (though its demonstration might require almost
microscopic examination, in contrast with the easy finding of pods on
"male" trees.) But, in the practical culture of fruiting honeylocusts,
and in our present scope of knowledge of their pollination requirements,
our plantings should include a handful of seedling (thornless) trees or
else some grafted trees of a thornless "male" selection such as the
Smith, in a ratio of about 1 Smith to 10, say, of Millwood.

It is unfortunate that the presumed male mutants of the fruiting
varieties, reported above by Mr. Moore, were destroyed when the
Hillculture plots at Auburn were discontinued. Perhaps similar ones will
show up elsewhere, and they will be worth looking for. Meanwhile, the
Smith variety (originally propagated through a mixup in scionwood
collection), has been demonstrated to be a satisfactory pollinator for
Millwood and Calhoun, and it, as grafted, is also a thornless tree.
Perhaps any thornless male seedling honeylocust tree, if its flowering
period coincides with that of the fruiting variety, might serve equally
well.--Note by J. C. McDaniel.]

Possibilities of Filbert Growing in Virginia

E. L. OVERHOLSER, Head, Department of Horticulture, V. P. I.,
Blacksburg, Virginia

More than four-fifths of the United States filberts are grown in Oregon
and nearly all the rest are produced in the State of Washington. Prior
to 1933, total filbert production in these two states did not exceed 500
tons, but production has since increased steadily and in 1945 it
amounted to 5,320 tons. The value of filbert production in the U. S. in
1945 was about 3 million dollars.[1]

As a wild hazel is native of Virginia and as filberts have been
profitably grown, especially in Oregon and Washington the question is
often raised as to wheth
