Mr. _Aubury_, in his manuscript notes printed with _Camden_’s _Britannia_, mentions it, “a double circle of stones, four or five feet high, tho’ many are now fallen down. The diameter of the outer circle 40 yards, and of the inner 15. He speaks of the avenue coming up to it, as likewise of our before-describ’d avenue, from _Abury_ to _West-Kennet_, set with large stones. One side, he says, is very nearly entire, the other side wants a great many.” He did not see that ’tis but one avenue from _Abury_ to _Overton-hill_, having no apprehension of the double curve it makes. And he erred in saying there was a circular ditch on _Overton-hill_. The view here is extensive and beautiful. Down the river eastward we see _Marlborough_, and the whole course of the _Roman_ road hence going along _Clatford-bottom_. We see a good way in the road to _Ambresbury_, and the gap of the _Wansdike_, where we pass thro’. Thence the _Wansdike_ skims the edge of all the hill tops to _Runway-hill_. There we enter upon the view presented in plate XXI. The _Roman_ road runs upon the edge of the hill, on the right hand of that plate, between the barrows there. It descends the hill, and runs to the left hand of _Silbury_, and close by it; and then up _Runway-hill_. Next we see _Oldbury_ camp, over _West-Kennet_ village. Then we may view the whole length of the avenue hence to _Abury_, and observe the two great curves it makes, to imitate the figure of a snake, as drawn in the ancient hieroglyphics. Coming from _Abury_ town it curves to the right-hand or eastward, then winds as much to the west, till it ascends this _Overton-hill_, full east. [Illustration: TAB. XVII. _A View of the_ South Temple _July 15 1723._] I observed the breadth of the avenue here is narrower than elsewhere, as being the neck of the snake. ’Tis 45 feet or 26 cubits, equal to the diameter of the inner circle here. And as it is narrower than elsewhere, they made the side-distance between stone and stone proportional, being two thirds of that in breadth. Mr. _Smith_, living here, informed me, that when he was a school-boy, the _Kennet_ avenue was entire, from end to end. _Silbury-hill_ answers the avenue directly, as it enters this temple, being full west hence. Here is a great number of barrows in sight from this place, two close by; and a little north-eastward that chain of barrows design’d in plate XXIX. the lower part, looking toward _Marlborough_. Human bones found in digging a little ditch by the temple, across some small barrows there, and where there were no barrows. Mr. _Aubury_ says, sharp and form’d flints were found among them; arguments of great antiquity. They were of the lower class of _Britons_, that were not at the charge of a _tumulus_.
