Kilruddery near Bray, on the old coach-road, is a romantic mansion seated in a deep valley in the midst of most picturesque scenery. Luggela, which may be visited from Powerscourt Park, has in its vicinity a lake of the same name, seated amidst an ocean of mountainous scenery, surrounded by dark and naked rocks, and presenting a sombre picture of silence and desolation: the rugged barrenness of the scene which encircles this abyss is finely contrasted, in one point, by an expanse of verdant lawn, together with some plantations, belonging to a cottage erected there by Mr. Latouche, as a banqueting retirement. A ride of a few miles, either from Dublin or Bray, leads to Powerscourt, a noble seat, the road to which is a glen between two vast ridges of mountains covered with wood, which have a very noble effect. The vale is no wider than to admit the road, a small gurgling river close to its side, with some narrow slips of rocky ground and shrubbery. The whole scenery is of a most magnificent character, and much improved by an immense conical mountain rising out of the glen, and seeming to forbid all exit or entrance. An excursion to this favoured spot combines within its arrangements the several beauties of the Scalp, the Sugar-Loaf Mountains, and the Dargle: the tourist may therefore bring them all within one day's visit, if time is short, or visit them in detail after a general view. The best method is to proceed from Dublin to Altadore, after which the road for a few miles leads over mountain scenery of a pleasing character until it approaches the head of a wide extended glen, with the ocean in front and the domain of Powerscourt covered with plantations and tillage; whilst the Scalp, a lofty mountain, shuts up the view in the north, and is finely contrasted on the opposite side of the compass by the Sugar-Loaf. Let the tourist now turn completely round, and he will discover a magnificent glen, richly covered with foliage, with an astonishing waterfall at its extremity, said to be 360 feet in height. Mr. Wakefield observes that these objects, however, form only a small part of the romantic scenery which fills this charming district; and he says that in the extent of about 6 m. from the Sugar-Loaf Mountains, and from the waterfall to the ocean, a similar distance, nature has scattered her picturesque beauties with so liberal a hand, that the view altogether reminds the spectator of some of those landscapes on canvas, in which the painter, indulging his genius, has collected such an assemblage of interesting objects as are seldom found combined together in nature. The glen already described is the far famed _Dargle_, or the _Glen of the Oaks_, so that it must have been as well wooded in ancient times,
