LOUTH, a county in the eastern part of Ireland, which extends in the form of a bow or half-moon, on the side of the ocean, being much longer than it is broad; it is bounded on the south and south-west by
the county of East-Meath, on the north-west by Monaghan, on the north by Armagh, and on the north-east by the bay of Carlingford, which parts it from the county of Down; it is watered by several small rivers which fall into the sea, and its south frontiers are watered by the river Boyne, which renders it fruitful and rich. The most considerable places are Drogheda, Ardes, Dundalk, and Carlingford.
