We now rejoin the Barrier. The passage of the Cambeck-water seems to have been guarded with some care. On the eastern margin of the stream, to the north of the Wall, is an earth-work raised a little above the general level of the surface, which here is somewhat depressed. Stones, which do not appear in the contiguous parts, lie scattered about the place. These circumstances seem to favour the idea of there having been some additional fortification in this part. The western bank of the stream consists of a bold breastwork of red-sandstone, rising about fifty feet above the level of the water. The fosse of the Wall has been deeply cut into this rock; it still remains in a state of great perfection. The old drove-road between Newcastle and Carlisle, which, for some distance west of this, runs upon the site of the Wall, or close by it, here avails itself of the fosse as a means of climbing the bank. The ditch of the Vallum is also discernible. The farm-house of Beck is partially constructed of Roman stones, and on the east side of the rivulet of Beck a few stones of the Wall are in their original situation. Headswood, as its name implies, occupies a commanding position. The ditch of the Vallum is at this place peculiarly bold, and is about thirty-five yards distant from the Wall. The fosse of the Wall [Illustration: Mural Stone, Leg. II. Aug.] bends round an object which has the appearance of being an additional fortification outside the Wall. At the west end of Newtown-of-Irthington are the remains of a large mile-castle; the stones still lie in confusion upon the site. The stone represented in the margin was found at this place. We next come to White-flat, where the rubble of the foundation of the Wall is very discernible and the ditch very deep. Hurtleton (the town of strife) is next reached; both lines of fosse are distinct and in close contiguity. In the corner of a field, called Chapel-field, there are evident signs of a mile-castle; the plough, however, has been drawn over the site. The two works, which between White-flat and this point have approached each other very closely, now quickly diverge, the Wall bending to the north. [Sidenote: IRTHINGTON.]
