proof they were there before the Roman road; but this is not a proper place to enlarge upon it. When it has gained the summit of the hill, it leaves Oldbury castle a little to the north: this is a great and strong Roman camp on the north-west point of the hill, overlooking Calne: the precipice on those two sides is altogether inaccessible, falling down in narrow cavities or ribs, as it were the great roots of a tree, with an odd and tremendous aspect; and that way there was need but of very slender work for its security: but on the other sides it is double ditched, having but one entrance to the east, and that fortified with a return of the outer ditch and inner rampire, very artificially: there is a ditch likewise across the middle, as if it had been inlarged with an additional intake westward: it is in the main of a squarish form, and has a very fine prospect. On the northern limit, in the highest part, seems to have been a _prætorium_. On this hill, which is wholly a chalky down, with a most delicate turf (and softer to walk upon than a Turky carpet) about a foot or two under the superficial earth, they dig great quantities of flints to mend the highways withal: one would imagine they had been spewed out of the hardening chalk at the creation, as extraneous bodies, though of greater specific gravity than itself. [Illustration: 42 Oldbury Castle _11 Iuly. 1723_. _Stukeley del:_] [Sidenote: +Wansdike.+] Return we to the Roman road, which proceeds across another valley, and so towards Runway hill, the highest in all these parts. This was famous for a battle in the late civil wars; and they oft find the bullets, when digging for the pebbles as afore mentioned; and below the hill they plough up the bones of the slain: but much more is Runway eminent for two mighty works of antiquity, this Roman way, and Wansdike. The most lovely prospect here will tempt even a hasty traveller to cast his eyes about him, and see all the country far beyond the Bath, and so proportionably quite around. I am not doubtful that it takes its name from the Roman way, which here has an unusual and the most curious appearance of any I have seen. I took pleasure in examining the particularity of it more than once; and it is a masterstroke of skill to conduct it down the north side of this long and steep hill (as I have so often remarked to be the condition of northern heights) to render it easy, or even practicable. When from the top of this hill you look towards Marlborough, which is full east, you may discern that the road curves a little northward, not discernible but in the whole: the reason is to be attributed to the river Kennet, thrusting it out somewhat that way; otherwise the true line should have lain a little more to the south of Silbury. To the right you see Wansdike, creeping all along from south of Marlborough (about two mile) upon the northern edge of the great ridge of hills, parting North and South Wiltshire, till it descends St.
