Inland Irish county in Leinster, surrounded by Waterford, Tipperary, Queen's County, Carlow, and Wexford, watered by the Barrow, Suir, and Nore; extremely fertile in the S. and E., producing fine corn, hay, and green crops; is moorland, and devoted to cattle-rearing in the N., where also anthracite coal is abundant. Kilkenny, the county town, is noted for a fine black marble quarried near it.
