A butternut tree, beside the road, or elsewhere, with room to grow, has a short trunk, and a low, broad head, with a downward droop to the horizontal limbs. The bark is light brown, the limbs grayish green, the twigs and leaves all ooze a clammy, waxy, aromatic sap, and are covered with fine hairs of velvety abundance.
Because it is low and rather wayward in growth, late to leaf out in spring, and early to shed its leaves in summer, the butternut is not a good street tree. It breaks easily in the wind, and crippled trees are more common than well-grown specimens. Insect and fungous enemies beset the species, and take advantage of breaks to invade the twigs through the chambered pith. Short-lived trees they are, whose brown, satiny wood is used in cabinet work, but is not plentiful.
The black walnut (_see illustrations, pages 31, 70_) is the second species east of the Rocky Mountains, and the tree chiefly depended upon, during the century just closed, by the makers of furniture of the more expensive grades. Black walnut wood is brown, with purplish tones in it, and a silvery lustre, when polished. Its hardness and strength commend it to the boat and ship builder. Gunstock factories use quantities of this wood. In furniture and interior woodwork, the curly walnut, found in the old stumps of trees cut long before, is especially sought for veneering panels. Old furniture, of designs that have passed out, are often sold to the factories, and their seasoned wood cut thin for veneering.
Walnut trees one hundred and fifty feet high were not uncommon in the forests primeval, in the basin of the Ohio and Wabash rivers. These giants held up their majestic heads far over the tops of oaks and maples in the woods. They were slaughtered, rolled together, and burned by the pioneers, clearing the land for agriculture. These men had a special grudge against walnut trees, they were so stubborn--so hard to make away with. How unfortunate it is that our ancestors had the patience to go forward and conquer the unconquerable ones. Had they weakly surrendered, and let these trees stand, we should have had them for the various uses to which we put the finest lumber trees to-day.
Unhappily, the growing of young trees has not been extensively undertaken to replace those destroyed. The newer forestry is awake to the need, and the loss may be made good, from this time forward.
