CUMBERLAND, a post-town, and capital of Alleghany county, Maryland, on the Potowmack, at the junction of Will's Creek, seventy miles west of Hagerstown, 130 east-south-east of Wheeling, and 150 west by north of Baltimore. It is a considerable town, and contains a courthouse, a jail, a market-house, a bank, and several houses of public worship. The mountains in the vicinity abound in stone and coal, great quantities of which are transported down the Potowmack in flat and keel boats. The Cumberland or great western road extends from this town to the banks of the Ohio at Wheeling. It was made by the government of the United States, and a survey has since been executed from thence to the Mississippi, 600 miles farther.
