Part 21

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.

The blue ash is common on the rich river lands along the principal tributaries of the Mississippi. Some of the finest specimens grow on the limestone hills of the Smoky Mountains. It is a tall, graceful, grey-stemmed ash. We shall know it anywhere as an ash tree by its opposite twigs and leaves, and by its dart-like fruits. It differs from all other ash trees in having four-angled twigs. The tree has a kind of blue dye in its inner bark. Cut out a piece and put it in water, and it is as if you had added a few grains of indigo.

The blue ash ranks high as a shade tree, and its wood is quite the equal of white ash. It is used for vehicles, for flooring, and for tool handles. It is especially desired for pitchfork handles.

The native ash of Europe is a large timber tree, whose range extends through Asia Minor. The wood of this tree had a wonderful reputation for general usefulness. Its tough, thin inner bark was used to write on before paper was invented. The wood was used for lances and spears, for bows, pikes, and shields by the soldiers, during ancient times. Every tool, vehicle, and implement of the farmer and mechanic were made of this wood. “Every prudent lord of a manor should employ one acre of ground with ash to every twenty acres of other land. In as many years it would be worth more than the land itself.”

The seeds of ash trees were used for fattening pigs. They were also used as remedies for many diseases. They were called birds’ tongues, from their shape, and every apothecary kept a stock of them. Ash wood makes the best of fuel, and its ashes, rich in potash, make a splendid fertiliser, especially in orchards.

One warning the old English rhyme offers regarding this tree. It is supposed to attract lightning. Oaks have the same reputation. On the other hand, tradition holds that a beech tree is never struck by lightning. There is opportunity, where these trees grow, and where thunderstorms are frequent, to notice how true are the popular beliefs.

Have you ever been warned by this old rhyme?

“Beware of the oak, it draws the stroke; Avoid the ash, it courts the flash; Creep under the thorn—it will save you from harm.”

THE HORSE-CHESTNUT AND THE BUCKEYES

When an English lad speaks of a chestnut, he means the horse-chestnut, and the chances are that he does not know anything about the American trees, whose sweet nuts we gather in the woods at home after the frost has opened their spiny burs. In America the European tree is planted very commonly for ornament and shade, and it is always called horse-chestnut here, except by English cousins who may be visiting us.

They ask us why we put the word “horse” before this tree’s name. For answer we pull down a twig, snap off a leaf, and show the scar of the leaf’s attachment to the twig. It is somewhat like the print of a horse’s hoof on the ground. Even the horseshoe nails are there, for a thread from each leaflet goes down through the leaf stem, and its fibres are buried in the twig. There are five or seven of these nail prints in the scar, depending upon the number of leaflets. Five is the usual number, but seven is not at all unusual.

An old tradition states that the people of Eastern countries feed these chestnuts to their horses to cure them of cough, shortness of breath, and other lung disorders. Upon this is based a second claim for using the word “horse” before this tree’s name. The quality of the fruit, however, is probably the best answer to the question. The coarse, large nuts are not fit for human food. It is quite common to think that horses can eat things too rank for our more fastidious taste. Horse sugar is the name of a small tree whose sweetish twigs are browsed upon by cattle and horses in wooded pastures. Horse-radish and horse-mint are coarser, more rank-growing kinds of plants, than their closely related species which are used for human food.

We shall know the horse-chestnut in the dead of winter by the large buds, the large hoof-print leaf scars, and by the pyramidal form of the tree. The twigs are stout, and they turn upward so that the largest of the varnished buds are held up like candles. The main branches leave the trunk with an upward curve, then bend outward and downward, then up again to hold the buds upright. The tree looks, therefore, like a great complex candlestick, with many arms and many candles. The twigs are stout, and they come out opposite each other on the branch. This is a peculiarity of few trees. It belongs to all of the members of the horse-chestnut family, which includes the buckeye trees, our native horse-chestnuts.

In early spring, watch the horse-chestnut tree outside your windows and along the streets as they begin to swell, and until they finally open. The tree lights all its candles when the brown, varnished outer bud scales fall, and the soft, silky inner ones, yellow as a candle flame, are revealed. On the side twigs the buds are smaller than on the tips. Out of each small bud comes a bunch of leaves. Out of the big buds come the flowers.

In June a big horse-chestnut tree holds up a thousand pyramids of white blossoms. Below each flower duster is an umbrella-like circle of leaves. Each blossom of the dense spike has in its throat dashes of yellow and red. The petals form a ruffled border. The curving stamens are thrust far out. Bees come in search of pollen and nectar.

After the flowers pass, green fruits appear, a few in a cluster, and all covered with spines. Not many of these reach full size. It seems to be enough for the tree to ripen one or two fruits in a cluster. In the autumn they turn brown, and the husk splits into three equal parts. Out of this spreading husk the brown nuts fall.

Now the boys assail the tree with sticks and stones, and the harvest of nuts is on. Who does not love them for their beauty alone? The great white spot is the place where they were attached to the husk. The kernel is as bitter as gall, and I know of no animal which eats it. If any one counts them useless, let him see the hoards of them which children gather, and use in their play. He will change his mind completely. Their glowing, soft colour is a feast to the eye, and they just fit the hand.

THE BUCKEYES

The Ohio buckeye is a little tree, but it has given its name to the Buckeye State. There must have been many of them in the virgin forest that the Ohio pioneer cut down to make room for his crops of corn and grain. He noticed these trees particularly because of a disagreeable odour that comes from the bitter sap. The chopping and handling of these trees intensifies this odour, which is noticeable even when one drives past a growing tree.

The name was given by some imaginative person who saw a resemblance between the smooth brown nuts and the soft brown eyes of a buck. The white of the eye corresponds to the dash of white on the nut. Deer abounded in the virgin forests, and no doubt it was one of the first settlers, a hunter as well as a farmer, who named the tree.

The flowers and leaves resemble those of the horse-chestnut, but are smaller, as the tree is. The number of leaflets is five, rarely seven, and they cluster on the end of a long leaf stem. The flowers appear in April and May, and are not conspicuous, for they are yellowish-green, and make little contrast with the new leaves.

One thing is to be said in favour of this ill-smelling tree. Its wood has been found to be the best kind for the making of artificial limbs. To this special use the lumber is chiefly devoted.

The sweet buckeye lacks the disagreeable odour of the Ohio buckeye, and its nuts are eaten by cattle. It is a handsome, large tree, with leaves of five slim leaflets, more or less hairy below, and on the veins above. The flowers are yellow and showy. Each corolla is drawn out into a tube, like a honeysuckle’s. The husks of the nuts are smooth. This species grows from Western Pennsylvania along the mountain slopes to Alabama, and on the prairies westward to Iowa. The nuts are full of starch, and these are ground into flour, which is used by bookbinders in making their paste. The reason why this paste is preferred is that destructive insects do not eat it as they do paste made of wheat flour.

A red-flowered buckeye tree of small size grows wild from Missouri to Texas, and east into Tennessee to Northern Alabama. This is not the same as the red horse-chestnut, which is sometimes seen in cultivation as a handsome tree, twenty to thirty feet high.

In the far West, the California buckeye is a wide-topped tree of good size, with leaves of the true horse-chestnut type, and white or rose-coloured flowers, in showy clusters, and smooth, pear-shaped nuts. This is the only one of our native species which grows beyond the Rocky Mountains.
