surround the island at its outermost limits, besides leading to the best points of view in the interior; and indeed it will be proper not to omit the prospect from a handsome temple which commands the whole of this enchanting scenery. The grotto ought also to be visited, and attention paid to the effect on coming out of it, when the contrast presents a beautiful effect, in two of these islands appearing to join, the streight between them having the semblance of a deep bay, whose extremity is lost amidst the sombre foliage in the back-ground. Behind these is the hill of the deer park, the lofty mountains behind which for a moment draw attention from the nearer beauties; but these latter must not be neglected, as their examination in all the neatness of artificial culture contrasts finely with the bleak and wild surrounding imagery of nature. The widest part of the loch is in the vicinity of Castle Archdall, where it resembles the sea, and presents a charming panoramic prospect if viewed from the little island of Ennismachcent, no less than 27 isles and islets surrounding the spectator. The prospect to the N. is the finest, when Castle Archdall is seen in all its glory of wood and water reaching on the left to a noble bay of considerable extent, bounded by lofty mountains softening into distance, and shrouding in their bosom a much venerated Roman Catholic cemetery, with a large stone cross standing on a pedestal at its entrance. In Lough Erne, the most celebrated island for holy purposes is _Devenish_, in which there are a round tower and considerable ecclesiastical ruins, some as early as the 12th century. These buildings are of the Augustinian order of monks; and the most ancient part is called St. Molaise's House, a vaulted building of hewn stone; coeval with which, in Mr. Ledwich's opinion, is the round tower; and both, as he supposes, of Danish origin. MINERALS. The mineralogist will find little here to interest him; but the geologist may discover much food for research; especially in the bogs that lie N. of Enniskillen, where sea shells are often found mixed in strata of white clay, 15 feet below the surface. This clay is calcareous; and the whole, in process of time, may become a bed of marble.
