The beauty of this Eurasian walnut tree would justify planting it merely for the adornment of parks and private grounds. Its broad dome of bright green foliage in summer, and its clean gray trunk and bare branches in winter, are attractive features in a landscape that has few deciduous trees. A fine dooryard tree that bears delicious nuts, after furnishing a grateful shade all summer, is deserving the popularity it enjoys with small farmers and owners of the simplest California homes.
As a lumber tree, the walnut of Europe has long been commercially important. It is the staple wood for gun-stocks, and during wars the price has reached absurd heights, one country bidding against its rival to get control of the visible supply. Furniture makers use quantities of the curly walnut often found in stumps of old trees. The heart wood, always a rich brown, is often watered and crimped in curious and intricate patterns, that when polished blend the loveliest dark and light shades with the characteristic walnut lustre, to reward the skilled craftsman.
In the United States this wood is rarely seen, because the trees are grown for their nuts. They require several years to come into bearing, are long-lived, have few enemies, and need little pruning as bearing age approaches.
THE HICKORIES
Americans have a right to be proud that the twelve hickory species are all natives of this country. Eleven of the twelve are found in the eastern half of the United States; one, only, strays into the forests of Mexico. No other country has a native hickory.
Indians of the Algonkin tribe named this tree family, and taught the early colonists in Virginia to use for food the ripe nuts of the shagbark and mockernut. After cracking the shells, the procedure was to boil and strain the mixture, which gave them a rich, soupy liquid. Into this they stirred a coarse meal, made by grinding between stones the Indian corn. The mush was cooked slowly, then made into cakes, which were baked on hot stones. No more delicious nor wholesome food can be imagined than this. Frequently the soup was eaten alone; its name, "Powcohicora," gave the trees their English name, part of which the botanist, Rafinesque, took, Latinized, and set up as the name of the genus.
Cut a twig of any hickory tree, and you realize that the wood is close-grained and very springy. The pith is solid, with a star form in cross-section, corresponding to the ranking of the leaves on the twigs. The wind strews no branches under a hickory tree, for the fibres of the wood are strong and flexible enough to resist a hurricane. (See illustrations, pages [6], [71].)
Hickory wood is unequalled for implements which must resist great strain and constant jarring. The running-gear of wagons and carriages, handles of pitchforks, axes, and like implements require it. Thin strips, woven into baskets for heavy market use, are almost indestructible. No fuel is better than seasoned hickory wood.
