Before crossing the Cambeck-water it may be well to remind the reader, that the river Gelt, on whose rocky banks the Roman quarrymen have left lettered memorials of their toil, is about four miles to the south of this place. With the view of clearly displaying the inscription, which has frequently been inaccurately engraved, the lithograph opposite to page 81, has been drawn to a scale which precludes the possibility of shewing the height of the cliff. The adjoining wood-cut partly supplies this deficiency; it exhibits another inscription, not of a very intelligible.[Sidenote: PIGEON-CRAG.] character, on the Pigeon-crag, which is a little higher up the water, and shews the general character of the scenery on this beautiful stream. The distance of these quarries on the Gelt, from the line of the Barrier, renders it very questionable whether large supplies were derived from them for the Wall. Hodgson remarks— The quarry at Helbeck-scar (the Written-rock) might serve for the largest stones for part of the Murus, and the stations at Brampton-old-church, and Walton-castlesteads; for the general purpose of the Murus, stone, however, could be got in places much nearer than Helbeck-scar. At the quarries of High and Low Breaks, about a mile and a half north of the Wall, there are marks of extensive ancient workings; the quarries are still in use and yield stone of good quality. The Written-rock will not be easily found by a stranger, but directions and assistance may generally be obtained from the workmen employed upon a modern quarry, which is not far from the spot.
