DUNMORE CAVE, 5 m. N.W. of Kilkenny, is one of the most remarkable in the island. Proceed to the Ch. of Mothe, a little to the southward of which, in a field on the slope of a gently rising hill, is the mouth of the cave, which opens into a large oval pit, about 40 or 50 yards wide, apparently formed by the sinking in of the surface, at the eastern end. To this there is a descent of 70 feet from the opposite quarter, over the rubbish of stone and clay; but the other sides of the pit are perpendicular. Rabbits often burrow near the entrance; and the first cavern, which is spacious, but of an irregular form, is generally a shelter for wild pigeons. To the roof of this cavern is an altitude of at least 50 feet; the floor slopes downwards, and towards the left the tourist arrives at a narrow passage which leads by a slippery ascent to the interior cavern. The difficulty of approach to this spot is amply repaid by the wonders within, where a great variety of stalagmitic concretions, added to the rugged forms of the rocks, exhibit a most singular and striking appearance. The tourist who wishes to explore all the wonders, must now proceed to the upper end, which becomes much narrower, but soon expands into a larger apartment. Beyond this there are other winding passages and other caves; but as neither Mr. Wakefield nor Mr. Walker seems to have explored them, it perhaps remains for some adventurous tourist to discover wonders equal to the caves of Trophonius or even Montesinos. Those who choose not to proceed further may consult Mr. Tighe's Survey of the County, where various other circumstances are stated. It is said that one of those passages leads to the other side of the hill, where day-light may be seen to enter through a narrow chink. In another of the inner caverns, imagination supposes the calcareous concretions to have assumed the form of an organ; in another, of a cross and altar. A stream of water passes through the cavern at a considerable distance from its entrance; and many skulls and other human bones have been found near to it, also in the more interior passages beyond it. Some of these skulls have been seen petrified, as it is called, or covered with the calcareous spar. The mineralogist may here pick up some specimens of an indurated clay, tinted by carbon, and called in the vicinity black chalk. Upon the whole, a visit to this place cannot fail to be highly gratifying to the tourist; though he will meet with some difficulties in exploring it, as the bottom is always damp and slippery, and rugged withal, from the stalactites formed by the dripping water on its very irregular flooring. ENNISTEAGUE, or INNISTIOGUE, 12 m. S.E. of Kilkenny, has a handsome Bridge and some pleasing scenery.--See the enchanting and picturesque glen at Woodstock, near Glanmore, with ruins of Ch. and Castle, in whose winding recesses nature and art have done every thing possible to embellish the scene.
