Tilia wood is soft, pale-colored, light, of even grain, adaptable for wood-carving, sounding-boards of pianos, woodenwares of all kinds, and for the manufacture of paper. The inner bark is tough and fibrous. It has been used since the human race was young, in the making of ropes, fish nets, and like necessities. It was a favorite tying material in nurseries and greenhouses until the more adaptable raffia came in to take its place. The bark of young trees is stripped in spring to make the shoes of the Russian peasantry. An infusion of basswood flowers has long been a home remedy for indigestion, nervousness, coughs, and hoarseness. Experiments in Germany have successfully extracted a table oil from the seed-balls. A nutritious paste resembling chocolate has been made from its nuts, which are delicious when fresh. In winter the buds, as well as the tiny nuts, stand between the lost trapper and starvation. The flowers yield large quantities of nectar, and honey made near linden forests is unsurpassed in delicacy of flavor.
About the time of Louis XIV, the French fashion arose of planting avenues to lindens, where horse-chestnuts had formerly been the favorite tree. The fashion spread to England of bordering with "lime trees" approaches to the homes of the gentry. "Pleached alleys" were made with these fast-growing trees that submitted so successfully to severe pruning and training. All sorts of grotesque figures were carved out of the growing lime trees in the days before topiary work in gardens submitted to the rules of landscape art, and slower growing trees were chosen for such purposes.
In cultivation, lindens have the virtues of swift growth, superb framework, clean, smooth bark, and late, profuse, beautiful and fragrant bloom, which is followed by interesting seed clusters, winged with a pale blade that lightens the foliage mass. One fault is the early dropping of the leaves, which are usually marred by the wind soon after they reach mature size. Propagation is easy from cuttings and from seed.
The American Linden, or Basswood
Tilia Americana, Linn.
The American linden or basswood is a stately spreading tree reaching one hundred and twenty feet in height and a trunk diameter of four feet. The bark is brown, furrowed, and scaly, the branches gray and smooth, the twigs ruddy. The alternate leaves are obliquely heart-shaped, saw-toothed, with prominent veins that branch at the base, only on the side next to the petiole. (See illustration, [page 86].) Occasionally the leaf blades are eight inches long. A dense shade is cast by a linden tree in midsummer.
The blossoms, cream-white and clustered on pale green, leaf-like blades, open by hundreds in June and July, actually dripping with nectar, and illuminating the platforms of green leaves. A bird flying overhead looks down upon a tree covered with broad leaf blades overlapping like shingles on a roof. It must look underneath to see the flowers that delight us as we look up into the tree-top from our station on the ground.
In midsummer the linden foliage becomes coarse and wind-whipped; the soft leaf-substance is attacked by insects that feed upon it; plant lice deface them with patches of honey-dew, and the sticky surfaces catch dust and soot. Riddled and torn, they drop in desultory fashion, their faded yellow not at all like the satisfying gold of beech and hickory leaves.
