Orkney, Lady, 176. The seat of this lady is an ancient building, which, from its situation on an eminence, commands a fine prospect of the Thames, and the adjacent country. The park, stored with rich woods, is rendered beautifully picturesque by its inequality of surface. Orr, Capt. 209. (_see Brickworth_) Osborne, Major, 210. (_see Milshall Park_) =Osterley Park=, 70, the seat of the Earl of Jersey. The house is a magnificent structure, of a square form, having a tower at each outward angle. The ascent to the east front is by a grand flight of steps, to an open saloon, or portico, which leads to the principal door of the hall. The apartments are spacious, fitted up in the most sumptuous and costly manner, and contain a good collection of pictures. The park is about six miles in circumference; it abounds with wood, and its grounds are beautifully disposed, the effect being considerably heightened by a charming lake, which is inhabited by a great variety of water fowl. On the margin of this lake stands an elegant menagerie, containing a large collection of exotic and curious birds; and the scenery on its banks, from the variety and arrangement, give it an appearance beautifully picturesque. =Ovington Place=, 84. Oxenden, Sir H. 9. (_see Broom Park_) P. =Padworth House=, 179, the seat of R. Clark, Esq. This is a noble mansion, and from its situation, standing on elevated ground, commands many extensive and beautiful prospects. The house is well sheltered by wood, and the grounds have an easy slope to the meadows in the valley, through which the limpid Kennet winds its course, adding considerable beauty to the landscape, as seen in various points of view. =Pains Hill=, 25, the seat of the Earl of Carhampton. These beautiful grounds were formed by the Hon. Charles Hamilton; a considerable part of which was taken from the barren heath. The south side is a bank above the river Mole, which runs at the foot of it. Availing himself of the inequalities of the land, his plantations were made, and buildings placed with the utmost judgment; a spacious piece of water was also formed, which, though considerably above the level of the river, is supplied from it by an ingenious, though simple contrivance. The present edifice is a handsome white building; the front, which is facing the river, is adorned in the centre with a pediment, supported by four columns, and bowed sides. The beauty and unexpected variety of the scene; the happy situation, elegant structure, and judicious form of the buildings; the flourishing state, uncommon diversity, and contrasted grouping of the trees, and the contrivance of the water, will not fail to excite the most agreeable sensations.
