Hite, to a point on the Shenandoah river, at the mouth of Fauntleroy's mill run, on the north side of the Shenandoah river; thence from the mouth of said run a straight line to the nearest top of the Blue Ridge of mountains; and thence on the eastern boundary of Frederick county to the beginning." Curtilage, used for the first time in any description, is a law term denoting the fenced-in area adjoining a dwelling house or a courtyard. The term often used now is dependencies. Warren, the third county created in 1836, lies over the Blue Ridge from and a little to the south of Clarke.
