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 Amer ican 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, ex cept 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 some what 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 leaf lets. Five is the usual number, but seven is not at all unusual.
An old tradition states that the people of East ern countries feed these chestnuts to their horses to cure them of cough, shortness of breath, and other lung disorders. Upon this is based a sec ond 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-chest nuts.
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 cluster 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.
