EMYVALE, a post-town, in the parish of DONAGH, barony of TROUGH, county of MONAGHAN, and province of ULSTER, 5¾ miles (N. by W.) from Monaghan, and 71½ (N.W.byN.) from Dublin, on the road from Monaghan to Aughnacloy; containing 123 houses and 571 inhabitants. This town, which is nearly on the confines of the counties of Armagh and Tyrone, consists principally of one street, and is skirted by a stream tributary to the river Blackwater, which, descending from the mountains on the west, frequently, becomes a rapid and dangerous torrent after heavy rains, On its banks is a large flour-mill, and in its bed above the town, is a quarry of greenstone. There is a constabulary police station, and petty sessions are held every fortnight in the town, in which is also a branch of the Glasslough dispensary. In the vicinity are several gentlemen's seats, which are noticed in the account of Donagh, which see.
