On Mount Etna, in Sicily, there is a famous chestnut tree. It stands on one of the lower slopes of the mountain, so that it is often visited. There are quite a number of huge chestnut trees in that neighborhood, each of which has a distinctive name. But the “Chestnut of a Hundred Horses” is much larger than any of the others. It is a very, very old tree, and the people who now live near it, are not sure how it first got its name. Some say it was named many years ago by a Spanish queen because its thick wide branches once sheltered her and her party of a hundred horsemen, from the rain. Others say it is so called because a hundred horses can be sheltered within, and around it. It is now the home of a shepherd, who has built a hut for himself, and a fold for his sheep, within the hollow of the tree. The trunk measures 190 feet around. It looks as if there were several trees growing together, but it is known to be all one tree. [Illustration: THE GREAT CHESTNUT TREE OF MOUNT ETNA.] In the centre of a graveyard, in the village of Allouville, in Normandy, there stands an oak that is over nine-hundred years old. Near the ground its trunk measures thirty feet in circumference. Two hundred years ago it was fitted up as a little chapel, and is used for that purpose to this day. The tree is hollow, as are all these very old trees. The lower part of this hollow is lined with wood, carefully plastered and wainscoted. This is the chapel. Above it, is a second story, and in this room lives a solitary man—a hermit. Above, in the branches, is a belfry, ornamented with a cross. In another part of France, there is an oak that is known to be fifteen hundred years old. It also is hollow, but every year, like the Hundred Horse Chestnut, and the Allouville Oak, it covers itself with thick and luxuriant foliage. The circumference of this oak is over 80 feet, and its branches spread over a circumference of 380 feet. The inside of this tree is used for a dining hall by pleasure parties. A circular bench has been cut out of the wood, and a dozen persons can sit comfortably around the table. The room has a glass door, and a window. Beautiful ferns and mosses spring out of the sides of the tree, and decorate this hall. Not far from Smyrna, in Asia Minor, there is a very old, and a very large Plane tree. It has three stems from one root. These join into one trunk at the height of about twenty feet from the ground, thus forming a gateway. The main road runs right through this gateway, and cavalcades of horsemen, and camel riders, and vehicles pass under this singular arch. There is another Plane tree in the island of Cos, which is almost as well known as that of Smyrna. Its spreading branches cover the whole of a large square of a city, and are so heavy that the old trunk is not able to bear their weight. The inhabitants of the city, proud of their tree, and anxious to keep it, have built columns of marble under the branches to support them.
