The Southstack, as already mentioned, is cut off from the promontory by a deep chasm thirty yards in width, through which the sea roars and boils with great force and impetuosity. To cross this formidable ravine an oriental rope-bridge was formerly employed, that is--a sliding basket was attached to the cable, which was secured at either side of the abyss; the passenger entered the basket, and by the ingenious working of lateral pulleys it was sent off or hauled in, according to the arrival or departure of visitors. This hempen apparatus was replaced in 1827 by a handsome suspension-bridge, on the same principles as that over the Menai. It was suggested by the intelligent veteran already mentioned, Captain Evans, and has answered every purpose contemplated in its erection. The roadway is five feet in width, and its height above high-water mark is about seventy feet. The airy span of this bridge is highly graceful and picturesque, and adds greatly to the interest of the picture. On the rock, close under the walls of the lighthouse, are several cottages for the use of the Superintendent and those under his command. The different points of view which it comprises are all deeply interesting to a stranger, particularly from the lighthouse, where the sphere of vision is greatly enlarged. [Illustration: THE EAGLE TOWER, CARNARVON CASTLE.] EAGLE TOWER, CAERNARVON CASTLE. Caernarvon Castle, of which the Engraving annexed presents so faithful and striking a resemblance, is a subject of no ordinary interest: it generally engrosses the attention of all strangers in these parts, and is, in every sense, one of the noblest specimens of castellated architecture in existence. Like so many others of similar design and execution, this fortress owes its origin to the policy of Edward the First, who built it, according to contemporary history, by appropriating the revenues of the See of York, then vacant, to the purposes of warlike enterprise and ambition. The town is understood to have arisen under the same auspices. The Castle defends it on the south by means of a narrow, deep moat in front. In its west wall are three circular towers, with two others on either side, and a narrow gate or entrance, over which is placed a bare-headed figure with flowing locks,--the statue of the founder,--holding in his left hand a sword, which he draws with his right hand,--or rather, perhaps, is returning to its scabbard, in allusion to the subjugation of the Welsh,--and a defaced shield under his feet. This gate leads to a narrow, oblong court. At the west end is a polygon, or many-sided tower, with three others of hexagonal form above, and eagles sculptured on the battlements, from which it received the name, preserved in the Engraving, of the "Eagle Tower." It is a noble structure, having ten sides, and a staircase of three hundred steps to the battlements. In this tower is the birth-chamber of Edward
