Our common ash trees are distinguished by colour, as the names indicate. A few well-marked differences are shown by the species, which are often found growing together in mixed woods.
The white ash is a tall, handsome, stately tree, with a trunk like a grey granite column. The white in its name is from the pale leaf linings, that illuminate the tree top in summer. The twigs are pale, and the bark is often as pale grey as that of a white oak. The slender, dart-like seeds are one to two inches long, with a wing which is twice the length of the round, tapering seed. They hang in thick clusters, paler green than the leaves, and often flushed with a rosy tinge in late summer. All winter the wind harvests the crop of seeds, and plants young white ashes wherever the darts fall on good ground.
The black ash is a slender, upright tree, with narrow head and stout twigs. The plump, leathery buds on the winter twigs are almost black, and the bark is a very dark grey. The foliage in summer is much darker green than that of any other ash, so the name is earned by buds, bark, and leaves. The seeds are flat and short, and the wing is broad and short, and deeply notched. A black ash leaf has all its leaflets stemless except the one at the tip. The white ash has a much fleecier foliage than that of the black, because each leaflet has a stem of its own.
The wood of the black ash splits readily into thin sheets, each representing the growth of a single year. The Indians taught the white men to make baskets out of black ash splints. They cut the tree down, sawed the log into the lengths required, split the blocks into pieces as wide as the splints should be. These sticks were bent over a board, and the strain separated the bands of dense, tough wood into the thin strips just right for basket weaving.
The red ash is a small, spreading tree, with a close head, slender branches, and crowded twigs. Its bark is reddish, closely furrowed, and scaly. The young twigs are covered with soft hairs. The leaves are a shiny yellow-green above, often a foot long, made of seven to nine slender leaflets, whose stems and veins have a silky down, that remains all summer.
Red ash seeds are extremely slender and long, and they hang on hairy stems.
The green ash has dark, lustrous foliage, the leaf lining green, like its upper surface. The bark is grey, and closely checked, and the twigs are smooth and slender.
This is the ash tree which grows in the regions of scant rainfall; in Utah, Arizona, and Texas. In the East it is found from Virginia to Florida. It is one of the beautiful shade trees in the regions where few trees grow well. East of the Alleghenies it is but one among many ash trees, and is little noticed; but in the far West, and on the treeless plains of Nebraska and Dakota, it is a far handsomer tree than its companions, the willows and the cottonwoods.
