The conscientious worker in the experiment stations is in the same category. He does his best work largely for love of it.
In addition to many letters and other valuable sources of information this survey covers reports from more than 150 planters of named varieties of nut trees. Many are also planters of seedlings from selected and named varieties with which they are experimenting and from which they are making selections for future tests. Some are experimenting with cross pollination. As one example of careful work, we have now on file blue prints from the New Jersey Department of Conservation and Development, from Gerald A. Miller, of Trenton, showing exact locations by name and number of one of the largest variety collections of hybrid walnut trees in the world. From the Brooklyn Botanic Gardens, Arthur H. Graves, Curator, we have valuable records of the breeding of chestnut trees, with selections made primarily for tree growth and timber production. There is also hope for some good nuts from the trees. The timber, in money value, is of course more important than the nuts. If successful, we shall again have both.
It is difficult to interest "hurry-up" Americans in planting trees for future generations. They want results now. But the sooner we develop reliable and adaptable fruiting trees for general planting, the sooner will thousands of people begin to plant trees. The late rapid growth of membership in this Association shows an awakened interest that could be swollen into a mighty flood of tree planters if good trees were available. If there were more agencies like the Tennessee Valley Authority, more trees of the better sort would be developed. Its tree crop activities have now been transferred to a "Forest Resources Division" under the supervision of Mr. W. H. Cummings, and its testing and selection work is going ahead steadily. Thomas G. Zarger, Jr., Botanist, is handling the black walnut work in connection with other investigations of "Minor Forest Products." The headquarters is at Norris, Tennessee. Charles V. Kline, now Assistant Chief of the Watershed Protection Division, still keeps his old interest in the black walnut and tree crop program. Definite and important results are bound to follow from so sustained and well organized a project. Most state agencies complain of lack of appropriations and help. The real trouble lies in lack of vision and knowledge upon the part of legislators. The President has proposed an immense program of communications and highway development as a post-war project. We suggest that fruitful land is still more important, and that highways through desert countries are almost unknown except as means for getting from one fruitful land to another. Perhaps this Association could do more than it has done toward spreading the gospel among legislatures.
The largest source of contribution to the survey is, of course, from the Northern United States. For purposes of tabulation, we have included everything north of Central Tennessee in this class. Nearly one hundred planters of nut trees contribute their experiences in this section. Of the lot, only fourteen of them plant trees for sale as nurserymen. Today we could keep more of them with stocks sold out. Seventy-six are interested in planting primarily for the production of nuts; fifty-seven, in grafting and budding trees from named varieties; forty-five in planting seed from the better varieties, either for production of stocks upon which to graft or, in large quantities, for observation and selection. As many as twenty-six are doing important work in hybridizing. Fifty-one are top-working young trees to better varieties. Only twenty-one count upon the growth of timber for a part of their profit. But certainly the growth of timber, especially black walnut, is not an item to be left out of consideration. Much, here, depends upon the manner of planting, whether in orchard or forest formation. However, even in orchard plantings, the stumps alone are valuable for beautifully patterned veneers.
Fifty-seven correspondents tell us that they are testing standard varieties, while forty-two are interested in discovering and developing new varieties, certainly an index to the pioneering and creative urge which dominates many of our members. As is to be expected, most of our newer members are thus far feeling their way by growing a few of the better varieties for home use. Only nine of the whole number say that they are working with nut trees at an experiment station.
As to the species of trees being planted, black walnut heads the list with eighty-nine planters. Persian walnuts are next with seventy-three, including five who specify Carpathians or Circassians. Sixty-eight are planting Chinese chestnuts, and sixty-four hickories. Filberts and pecans are tied with fifty planters each; forty-eight say they are planting hazels; forty-three heartnuts; and forty-two persimmons—if we may include these trees for the time being among the nuts. Thirty-eight are planting butternuts; thirty-two, Japanese Walnuts; twenty-eight, pawpaws; twenty-seven, mulberries; twenty-four, Japanese chestnuts. After these, in order, come almonds along the southern borders, beech toward the north, hicans, tree hazels, oaks, Japanese persimmons, honey-locust, jujube, black locust (the correspondent explains, "for bees and chickens"), Manchurian walnuts, and finally, coral and service berries.
As an indication of the adaptation of species and varieties to the climates in which these men, and several women, are working, they listed at out request the following native trees found most plentifully in their sections. Black walnuts and hickories stand at the head of the list, as reported by seventy-five correspondents each. Then follow in order, butternuts, hazel, beech, oaks (probably overlooked by many), pecans and chestnuts.
Of nut trees found sparingly in these sections, butternut trees, surprisingly, take first place, indicating broad adaptation but a certain weakness, perhaps a slow susceptibility to blight or fungi, which prevents this tree from being found plentifully. It is significant that it is found most plentifully in the more rigorous areas of New England where fungous ravages are discouraged by cold. Add chinquapins to the number of scarce trees, and the list is complete.
As a further gauge of climatic conditions, fifty reported that peaches are reliably hardy in their sections, while fifty said they are not. This, according to the late Thomas P. Littlepage, is a fairly reliable index to the climatic adaptability of present varieties of northern grown pecans. Ninety-two planters reported that their seasons are long enough to mature Concord grapes. Only four said "no." For Catawba grapes? "Yes," said forty-two; "No," fourteen. For field corn? "Yes," ninety-three; "No," four. This question was improperly asked. Field corn varies too widely in length of maturity for accuracy in this respect.
Lowest temperatures expected range from 8°F above to 30°F below zero, with the usual lower range in the greater portion of the northern states, from zero to 12° below. Lowest known temperatures range all the way from 10° to 52° below, but in most portions from 15° to 35° below.
