Here are two famous Riding Houses, one the pride of the author of the great work on Horsemanship in Stuart times. This is used nowadays as a picture gallery, the late Duke of Portland having built another of dimensions almost double. To my thinking, one of the chief beauties of Welbeck is the gilded gateway opening to the avenue on the road from Worksop to Ollerton--surely one of the most graceful and yet imposing structures of its kind in the country. Another and more singular attraction consists of the subterranean roadways--gigantic mole runs the cause of whose creation is, and probably always will be, a mystery to the world in general. The pleasure gardens are stocked with rare trees, and the vast lake has so natural an appearance that one forgets that it was made by human folk. The kitchen garden is notably fine: we are told that it covers thirty acres, and that the houses for peaches and other luscious fruits extend over a quarter of a mile. There is a story of a monstrous bunch of Syrian grapes having, some generations ago, been grown there, and sent by the duke of that time across country to Wentworth House. It weighed nineteen and a half pounds, and was carried--as was the trophy taken by the spies from Canaan--attached to a pole. Finest of the Welbeck trees is the "Greendale Oak", which in 1724 was transformed, by cutting, into an archway, the aperture being 10 feet 3 inches high and 6 feet 3 inches wide, so that a carriage, or three horsemen riding abreast, could pass through. From the branches cut off at that time a cabinet was made for the Countess of Oxford--a fine piece of furniture, inlaid with a representation of her spouse driving his chariot and six through the opening.
