Nothing now remained but to set fire to the train, and the Surveyor was exceeding curious to observe the effect of the explosion, which indeed was wonderful; for this small quantity of powder not only lifted up the whole angle of the tower, with two arches that rested upon it; but also the two adjoining arches of the isles, and all above them; and this it seemed to do somewhat leisurely, cracking the walls to the top, and lifting up visibly the whole weight about nine inches, which suddenly tumbling to its center, again caused an enormous heap of ruin, without scattering, and it was half a minute before this huge mountain opened in two or three places and emitted smoke. The shock of so great a weight from a height of two hundred feet, alarmed the inhabitants round about with the terrible apprehensions of an earthquake. A second trial of the same kind, was made by a person appointed by Dr. Wren, who being too wise in his own conceit, disobeyed the orders he had received, put in a greater quantity of powder, and omitted to take the same care in closing up the hole, or digging to the foundation; but though this second trial had the desired effect, yet one stone was shot as from the mouth of a cannon to the opposite side of the church yard, and entered a private room where some women were at work; but no other damage was done, besides spreading a panic among the neighbours, who instantly made application above against the farther use of gunpowder, and orders were issued from the council board accordingly. The Surveyor being now reduced to the necessity of making new experiments, resolved to try the battering ram of the ancients, and therefore caused a strong mast forty feet long to be shod with iron at the biggest end, and fortified every way with bars and ferrels, and having caused it to be suspended set it to work. Thirty men were employed in vibrating this machine, who beat in one place against the wall a whole day without any visible effect. He however bid them not despair, but try what another day would produce; and on the second day the wall was perceived to tremble at the top, and in a few hours it fell to the ground. In clearing the foundation, he found that the north side had been anciently a great burying place; for under the graves of these latter ages, he found in a row the graves of the Saxons, who cased their dead in chalk stones; tho’ persons of great eminence were buried in stone coffins: below these were the graves of the ancient Britons, as was manifest from the great number of ivory and wooden pins found among the mouldered dust; for it was their method only to pin the corpse in woollen shrouds, and lay them in the ground, and this covering being consumed, the ivory and wooden pins remained entire.
