bridge, for a fall from it would mean certain death on the jagged rocks more than a hundred feet below. [Illustration: DUNLUCE CASTLE.] The first thing that strikes one after examining the ruins is the unusual thinness of the walls. They are no thicker than those of a modern stone-built house. The reason of this is easily understood; for when the castle was built, which must have been before cannons were so perfected that they could be used for battering down buildings, it was absolutely impregnable, as no battering-ram, or mediæval siege-engine, could by any possibility approach near enough to the walls to be used against them. There was, therefore, no necessity that the walls should be thick. The space on the top of the rock is entirely covered with the ruins of the castle. The walls rise up sheer from the most outward margins of the rock. On looking out from one of the narrow windows the sea is straight below one. When the castle was inhabited its inmates must have had an awful experience during the storms that so often sweep over the wild west and north coast of Ireland, when the giant waves of the stormiest ocean in the world beat against the rock on which the ruins stand. If such a place was secure against the assaults of men, it was not secure against the fury of the elements; and it would seem that some of the cliff did at one time give way, for there are some gaps in the walls that appear to have been caused by rock, upon which they were built, having given way. The Giant's Causeway and Dunseverick Castle are both in the immediate vicinity of Dunluce, only a few miles west of it; both are well worth seeing; but nothing on all that magnificent, iron-bound, cliff-guarded coast of Antrim can compare in interest with Dunluce. The isolated, almost sea-surrounded rock on which it stands, the great bridge that connects it with the mainland, the narrow and dangerous footpath overlooking horrible depths, and over which the castle can only be entered, make it one of the grandest and most suggestive ruins in the world. Dunluce is a revelation. It shows, perched on its storm-beaten, once impregnable rock, the awful savagery of the time when might was the only law recognised by humanity; and that only a few centuries ago life and property were no safer in Christendom than they are to-day in the Soudan.
