Leitrim, a maritime county in Connaught, between Donegal Bay on the N.W., Fermanagh N.E., Cavan E., Longford S.E., Roscommon and Sligo S.W. It is of an hour-glass shape, and the centre is occupied by Lough Allan. The county is 52 miles long, and contains 588 square miles. In the north is a high tableland reaching to 1,486 feet in Lugnaquila. The south is wooded and more level. The rivers are the Shannon (flowing S.W. and forming part of the boundary), the Bonnef, Bundrow, and the Bunduff. Other loughs are Maclean, Scur, Gill, and Melvin, and a canal leads from Carrick-on-Shannon to Lough Erne. The central part is in the Connaught coal-field, and ironstone, lead, copper, manganese, and yellow ochre are found; and there are also sulphur and chalybeate springs. Some coarse linens, woollens, and pottery are manufactured. The county returns two members to Parliament, and the capital is Carrick-on-Shannon.
