Bidding adieu to Berkeley and its paternal landlord, we resume the steel road (that well-worn phrase of the "iron way" is a complete misnomer) with another glance of familiarity at the beautiful confluence of Sir John's Run with the Potomac, where the sunny waters still seem to murmur of the landing of Braddock's army and the novel disturbance of James Rumsey's steamer. The mountains extending from this point, the recesses of the Blue Ridge, in their general trend south-westerly through the State, are one great pharmacy of curative waters. Jordan and Capper Springs, in the neighborhood of Winchester, lie thirty or forty miles to the south; and beneath those are imbedded the White, Black, Yellow, and we know not how many other colors in the general spectrum of Sulphurs. It would perhaps be our duty to indicate more exactly the Bethesdas of this vast natural sanitarium, to which our present course gives us the key, but that task has already been performed, in a complete and very attractive manner, by Mr. Edward A. Pollard in his little work _The Virginia Tourist_. Our present task is to attain the main wall of the Alleghany Mountains, which we do at the town of Cumberland, after passing through the grand curved tunnel at Pawpaw Ridge, and crossing Little Cacapon Creek, and traversing the South Branch, which is the larger and true Potomac, and admiring the lofty precipices, with arched and vaulted strata, on South Branch Mountain and at Kelly's Rocks and Patterson Creek.
