extensive hunting-stables, coach-houses, and that marked feature of Welbeck, the covered "gallop," one thousand and seventy-two feet long, with large "hanging rooms" at either end: these too are covered with glass, so as to get their light from the top. The whole place abounds in subterranean apartments and passages, while above ground are extensive gardens and dairies. In the gardens are the peach-wall, one thousand feet long, a similar range of pine-houses, a fruit-arcade of ornamental iron arches stretching nearly a quarter of a mile, with apple trees trained on one side and pear trees on the other, and extensive beds of flowers and plants. To construct and maintain all this curious magnificence there are workshops on a grand scale. This eccentric duke, who practically denied himself to the world, and for years devoted his time to carrying on these remarkable works at an enormous cost, employed over two thousand persons in burrowing out the bowels of the earth and making these grand yet strange apartments. When finished he alone could enjoy them, for Welbeck was for a long time a sealed book to the outer world. But the eccentric duke died, as all men must, and his successor opened Welbeck to view and to the astonishment of all who saw it. A few months ago the Prince of Wales and a noble company visited the strange yet magnificent structure, and then for the first time the amazed assemblage explored this underground palace in Sherwood Forest, and when their wonder was satisfied they turned on the myriads of gas-jets, and amid a blaze of artificial light indulged in a ball--an unwonted scene for the weird old abbey of the eccentric and solitary duke. Like the fairies and mermaids of old in their underground palaces, the prince and his friends at Welbeck right merrily "Held their courtly revels down, down below." Also in this neighborhood is Newstead Abbey, the ancient seat of the Byrons. It is about eleven miles from Nottingham, and was founded by the Augustinians in the time of Henry II. In 1540 it came into possession of Sir John Byron, and a century later was held for King Charles. The poet Byron's bedroom remains almost as he left it, and on the lawn is the monument to his favorite dog, "Boatswain." The abbey also contains several relics of Livingstone, the African explorer. Near it is Robin Hood's Cave, and the neighborhood is full of remains of the famous chieftain, such as his Hill and his Chair, and Fountain Dale where Robin encountered Friar Tuck. NEWARK.
