Butternuts are generally too scarce to justify much attention. They could probably be hulled by vegetable paring machines quite as efficiently as are walnuts but, so far as known to the writer, this has not been tried.
Beechnuts make excellent food for poultry and certain kinds of livestock. To convert the crop into cash is largely a matter of using the land under the trees for the right sort of grazing. In European countries beechnuts are highly valued as a source of salad oil. Mr. Bixby of this association is taking steps to procure trees bearing as large sized nuts as possible with a view to subsequent breeding. So far as known to the writer beechnuts in this country are not gathered in quantity.
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.
