SWATTERAGH, a village, in the parish of MAGHERA, barony of LOUGHINSHOLIN, county of LONDONDERRY, and province of ULSTER, 3½ miles (N.) from Maghera, on the road to Coleraine, and on the river Clady; containing 204 inhabitants and comprising 50 houses, which, with the exception of one, are small and indifferently built. Here is a small corn-mill, the water from which, after passing under the bridge, divides, and making a curious circuit, forms an extensive island. The country around is barren and badly cultivated, being esteemed the worst part of the Mercers' Company's estate; but a change may be expected, as the leases have lately fallen into their own hands. In the village is a meeting-house for Presbyterians in connection with the Synod of Ulster, of the third class; also a large and handsome school-house, chiefly supported by the rector and his lady.
