BEECHNUTS

By Willard G. Bixby, Baldwin, N. Y.

Although the association has now been in existence 20 years there has so far been little progress, we might almost say no progress, made in getting an improved beechnut.

All have agreed that the flavor of the beechnut was excellent, that it had a shell so thin that it could be opened with a pocket knife, that it was an oily nut and would keep, like the thin shelled hickories, walnuts, etc., and not a starchy one, which would dry out like chestnuts and acorns, that it would grow and bear well in northern sections where the best nuts we have do not grow well, but also that it was so small as to practically nullify the above mentioned excellent qualities. If we ever get a beechnut the size of a chestnut we shall have a most needed addition to our nut bearing trees, but there has been so little hope of finding such that no one has paid much attention to the beech. As a matter of fact not within the last ten years have there been any prizes offered for beechnuts except those provided by the writer at his own expense, neither have there been at any time during the writer's recollection any varieties suggested excepting one or two by Omer R. Abraham, Martinsville, Ind., which nobody has growing, so far as known to the writer.

It was thought that there might be a large fruited species of beech growing in some part of the world as is the case with the chestnut, walnut, hickory and hazel, and that it would only be necessary to import it to get what was needed, or at least to make a good start in getting what was needed. Rehder in his wonderfully helpful "Manual of Cultivated Trees and Shrubs" gives seven species of beech, one in America, Fagus grandiflora, one in Europe, F. sylvatica, two in Japan, F. sieboldii and F. japonica, two in China, F. longipetiolata and F. engleriana and one in Asia Minor, F. orientalis. These are growing in the Arnold Arboretum and leaves, buds and fruits are to be seen in the herbarium there. A day spent there, however, half in the arboretum and half in the herbarium, convinced the writer that there is at present no large fruited species of beech known to botanists. There is an incompletely known species of Chinese beech, F. lucida, whose fruit is not in the Arnold Arboretum. While it is of course possible that there may yet be a large fruited species somewhere in the world, still the relatively slight differences in the leaf, bud and fruit of the seven species already known makes this seem improbable and leads us to conclude that the genus "Fagus" is the most uniform in the species that make it up of any genus of nut bearing trees. This seemingly reduces us to the necessity of seeking variation in species already known.

Fagus sylvatica has been by all odds longest in cultivation and many varieties are known. Rehder lists 17 principal varieties with many other sub varieties. These have leaves varying in color, purple, copper color, pinkish, yellow and whitish spotted with green, beside the usual green, also in shapes of leaves, some very narrow almost linear, some very small and deeply toothed, others large and roundish up to 3 in. broad and 5 in. long. The varieties vary in bark from the smooth bark typical of the beech to bark like that of the oak. They also vary in habit of growth, being mostly erect but some pendulous and some dwarf with twisted contorted branches. But no one seems to have ever heard of a large fruited beech.

It is inconceivable however, that a tree can vary in every particular except in the fruit and it is believed that it only requires sufficient searching to find large fruited varieties. There are difficulties, however, in the way of finding unusual beeches which do not occur with walnuts, chestnuts and hickories, which are trees where the nuts have such merit that they are usually spared even if in the middle of a cultivated field, while the beech is usually a forest tree. A nut contest brings hundreds and thousands of walnuts and hickories but only very few beechnuts. Correspondence with the forestry departments of every state having such departments generally evinced interest in the search for a large fruited beech, but those replying universally disclaimed any knowledge of such.

While it is believed that there are such in America, perhaps as many or more than in Europe, and efforts should be made here to find such, there are many reasons for believing that a search in Europe will be more immediately productive of results than will the search here. The beech is much more esteemed in Europe than here and has been extensively planted in forests that for centuries have been operated for constant production of timber. It is believed that the contents of those forests are as a class better known to their keepers, at least the beeches there are better known than in the forests in the United States. The number of propagated ornamental varieties noted in the second paragraph gives evidence of this. The history of one or two of these varieties will make this clearer.

Three beeches with red or copper colored leaves as far back as 1680 were recorded as growing in a wood near Zurich, Switzerland. Most of the purple beeches now growing are believed to have been derived from a single tree discovered in the last century in a forest in Thuringia in Germany. There may be or may have been many such in America but they would not have appeared valuable to the woodmen who probably would be the only ones who would see them and then the leaves would not have been visible in the winter when trees are most frequently cut. That the Deming purple black walnut is in existence is due solely to the observation and action of Dr. Deming who gathered scions and got them growing before the original tree had been cut for the purpose of getting space for improving a road. That this tree could be seen from the road was how it came to the attention of Dr. Deming. Had it been in the midst of a large forest it might have been cut in winter for timber without the cutter knowing it was unusual.

That we have such a wealth of varieties of the beech valuable as ornamental trees and none valuable for the large nuts they bear, certainly suggests that the tree varies in every way except in the size of the nuts it bears, but this is not believed to be so. The growing of ornamental trees is an old industry. There are hundreds of nurserymen today growing ornamentals and only few in comparison growing nut trees. It is not so many years ago that there were none growing nut trees. A beech with purple leaves appeared valuable 100 years ago and was disseminated by nurserymen while one with nuts 10 times normal size would probably not have been propagated for there would not have been sale for it. It would have only been known locally as unusual and probably the tree would have been cut for timber when it reached the proper size.

The search for a large fruited beech is not going to be easy but it is believed that persistent work will eventually triumph, much as the 1929 contest brought more shellbark hickories of value to the attention of the association than all previous contests put together. The shellbark is a tree the best varieties of which it is difficult to learn about. Unlike the shagbark hickory it is not generally found growing near buildings or in fields or pastures. Its natural habitat is the bottom lands of the Mississippi River and its tributaries, lands that are overflowed part of the year. There will have to be a campaign, perhaps for several years, till people begin to look for large fruited beeches; then will come a harvest of them.

The relatively few beeches that have come in to the contests suggests that methods used heretofore should be somewhat modified in beechnut search. Probably a campaign of education among foresters might be more productive of results than among farmers, at least it should supplement it. The search for improved beechnuts evidently has more different kinds of difficulties than the search for any other nut and considerable thought on the matter leads me to suggest that a committee be appointed to study the nut and to seek large fruited specimens especially to look into methods for getting them and report to the association a year hence, said committee to finance itself.

This suggestion is made because it is believed that efforts made in Europe to find a large fruited beech will be more immediately productive of results than in America for the reasons noted above. Even if the committee consists of but one man correspondence abroad would be better carried on in the name of a committee of the association than in the name of an individual and it is believed would be more productive of results.
