“This rule would certainly demand the repair and retention of the later roof, and even, at first sight, of the later window, and between these conflicting views I for a considerable time oscillated, in a way which may have appeared weak to others, and was certainly most painful to myself. “I eventually took an intermediate course, which I think will be admitted to be justified by the result. “As regards the roof, though it was so bad as to necessitate its being taken down, and though all its main beams (I think) but one had to be renewed, the remainder, including much good carving and many armorial bearings, was capable of reparation. As regards the original intention of groining, I found unquestionable proofs that it had been relinquished, if not by the original builders, yet certainly by the reconstructors after the fall of the tower in 1220, for these builders had inserted niches just where the vaulting would come. They had also erected the upper range of lancet lights at the east end in a form incompatible with vaulting. “These considerations led me at length to determine to relinquish the idea of groining, and to return to my first intention of restoring the later and existing roof. “The case, however, was different with the upper east windows, for not only was the later insertion so decayed as to demand renewal, but on searching below its cill we found those of the original lights still _in situ_, while on working the mine of _débris_ which existed in the dead walls added to the original sides, we found not only evidence sufficient to show the precise design of the ancient eastern lancets, but sufficient to go a considerable way in reconstructing them with their own ancient materials, though we found no details to enable us to complete either the high gable or its flanking turrets. “While, then, I arrived at the conclusion that the fifteenth-century roof should be restored, I also felt convinced that, as regards the lancet lights, I had discovered just such _special circumstances_ as would justify and almost demand the restitution of their original forms.
