"_5th September, 1814._--Wake, or rather rise at six, for I have waked the whole night, or fallen into broken sleeps only to be hag-ridden by the nightmare. Go ashore with a heavy heart, to see sights which I had much rather leave alone. Land under Dunluce, a ruined castle built by the MacGilligans, or MacQuillens, but afterwards taken from them by a Macdonnell, ancestor of the Earls of Antrim, and destroyed by Sir John Perrot, Lord-Lieutenant in the reign of Queen Elizabeth. This Macdonnell came from the Hebrides at the head of a Scottish colony. The site of the castle much resembles Dunnottar, but it is on a smaller scale. The ruins occupy perhaps more than an acre of ground, being the level top of a high rock advanced into the sea, by which it is surrounded on three sides, and divided from the mainland by a deep chasm. The access was by a narrow bridge, of which there now remains but a single rib, or ledge, forming a doubtful and a precarious access to the ruined castle. On the outer side of the bridge are large remains of outworks, probably for securing cattle, and for domestic offices--and the vestiges of a chapel. Beyond the bridge are an outer and inner gateway, with their defences. The large gateway forms one angle of the square enclosure of the fortress, and at the other landward angle is built a large round tower. There are vestiges of similar towers occupying the angles of the precipice overhanging the sea. These towers were connected by a curtain, on which artillery seems to have been mounted. Within this circuit are the ruins of an establishment of feudal grandeur on the large scale. The great hall, forming, it would seem, one side of the inner court, is sixty paces long, lighted by windows which appear to have been shafted with stone, but are now ruined. Adjacent are the great kitchen and ovens, with a variety of other buildings, but no square tower, or keep. The most remarkable part of Dunluce, however, is that the whole mass of plum-pudding rock on which the fort is built is completely perforated by a cave sloping downwards from the inside of the moat or dry-ditch beneath the bridge, and opening to the sea on the other side. It might serve the purpose of a small harbor, especially if they had, as is believed, a descent to the cave from within the castle. It is difficult to conceive the use of the aperture to the land, unless it was in some way enclosed and defended. Above the ruinous castle is a neat farmhouse. Mrs. More, the good-wife, a Scoto-Hibernian, received us with kindness and hospitality which did honor to the nation of her birth, as well as of her origin, in a house whose cleanliness and neatness might have rivalled England. Her churn was put into immediate motion on our behalf, and we were loaded with all manner of courtesy, as well as good things. We heard here of an armed schooner having been seen off the coast yesterday, which fired on a boat that went off to board
