latory. There the heavy sandstone base of the corner pillar (g) was still in situ. It measured twenty-five inches by twenty inches, and stood nine inches high. It was splayed on three sides. On the fourth, or south, side it was only roughly hammer-dressed, as though that portion had been imbedded in the paving of the ambulatory. On the top of this base was a single stone of the pillar itself, sixteen inches square and seven inches deep. On the south side of the ambulatory, again, only the pillar lying immediately to the west of the corner-stone had left any traces. Here was a heavy base (f), twenty-two inches by twenty-three inches by ten inches, splayed carefully towards the north, less carefully on the west, and left quite rough on the other two sides. Upon this base lay a single stone of the pillar it had supported. This measured fifteen inches by fourteen inches by seven and a half inches, and was of dressed sandstone. On the north side hardly anything was found but the circular settings of cobble stones on which the bases had been set. On the east side the evidence obtained was more important. The base of the first pillar from the south-east corner (h) was in situ. It resembled those already described, and was splayed on the north, south, and west, but rough on the east. The next base immediately to the north (i) consisted simply of a large sandstone block, very roughly shaped, and measuring twenty-two inches by twenty-one inches by twelve inches, lying on a slightly larger flat undressed slab of sandstone, five inches thick, which appeared to rest on cobbles. The place of the next base towards the north (j) was marked by a single squared block twenty inches by sixteen inches by ten inches. None of the other remains gave much indication of details.
Indications of Alteration
The impression left by these bases was that the pillars had been rude in execution, and that old material had been employed in their construction, while it seemed quite evident that the pillars on the south side of the entrance had, during some process of alteration, been moved from their original positions, probably with a view to widening the ambulatory. On the south-east, beside the corner base (g) already described, an older foundation was brought to light. It was roughly square in shape, measuring forty-two inches by forty inches, and consisting of two layers of cobble stones embedded in clay. The sandstone base rested partly on the corner of this foundation, partly on disturbed soil. Precisely similar conditions were observed on the site of the second pillar on the south side (f), while in the case of the first pillar from the corner on the east side (h) the older cobble foundation lay immediately to the south.
