NEWTON LIMAVADDY, 12 m. N.E. of Derry, is a neat town of one street, seated in a woody glen watered by a stream, and surrounded by beautiful scenery. Between it and Derry are some very fine views of the latter city; the Lough appearing to great advantage, bounded by a bold and precipitous hill towards the north; also a seat of the Beresford family, with a fine approach through a wood of stately oaks, and a rich underwood of holly. Accommodations and roads good. At Dungiven, 6 m. S.E., see the quarry of Alknever, which produces very fine sandstone of the best quality and of a tawny colour, not unlike Portland stone. Extensive mountain scenery, and pleasing landscapes on the river Roe. See the Old Castle, ancient Ch. and Monuments; numerous Raths, and curious Cave 2 m. distant. Magilligan is famous for its rabbit-warren. MINERALS. Iron ore:--near Castle Dawson. Small veins of lead and copper. Crystals found near Dungiven.
