Regaining the high grounds, the Wall for a short space is found to possess less than its usual interest; the ground on the east side of the Bradley estate was formerly common, and the object of our study was every man’s prey. Other objects of inquiry, however, abundantly relieve the attention. Langley castle, on the south bank of the Tyne, is in sight, and during our western journey will long continue to be so. It is a square building strengthened by rectangular towers at the corners. Formerly a seat of the Percys, it became afterwards the property of the Radcliffes. It passed, on the rebellion of 1715, along with the other possessions of the earl of Derwentwater, into the hands of the commissioners of Greenwich Hospital, who at present retain it. Destroyed by fire at an early period, it has never been repaired; its masonry is notwithstanding in excellent preservation. On a clear day the singularly strong tongue of land on which are the ruins of Staward-le-peel, may also be discerned to the south. But, more to our present purpose, the high, brown hill of Borcum, from which the Romans obtained much of the stone used in the construction of this part of the Wall, is in the foreground. [Sidenote: ANCIENT QUARRY] An interesting discovery was made here in 1837, to which subsequent reference will be made. On opening an ancient quarry on the top of it, near the ‘longstone,’ a workman found a small copper vessel, containing a large number of Roman coins; four of these were of the time of Hadrian, and all the rest, of previous reigns. Those of Trajan and Hadrian were as fresh as if new from the die. The conclusion is natural, that the quarry had been last wrought in the time of Hadrian, the Wall itself being possibly of the same date. An extensive earthen camp is on the summit of the hill, probably raised by the soldiers who were engaged in quarrying the rock. Greenlee-lough is to the north; on its western margin is a modern structure, Bonny-rig, the property of sir Edward Blackett. Proceeding westward, the Wall again rises into notice. ‘Much of it remains of very various thicknesses, the whole of the perpendicular outsets and insets being on the south side.’ [Sidenote: HADRIAN SLAB.] On the tail of the crag on which we now are, the farm-house of Bradley stands. Built up in the doorway of its old kitchen, was a stone, now at Matfen, bearing the fragment of an inscription. Another fractured slab, formerly in the possession of the ‘judicious’ Warburton, and now at Durham, when joined to it, gives an inscription precisely similar to one immediately to be noticed, with the exception of a letter or two in the line of the fracture. The fragments, doubtless, as Hodgson conjectures, formed one stone, deposited in the foundation of some castellum in this neighbourhood, as a memorial of its erection by Hadrian. The wood-cut annexed has been prepared from drawings carefully made of the two portions in their separate localities.
