“Stones which looked in good condition pealed off when touched with a penknife, and mouldings which looked sound, crumbled between my thumb and finger. A great deal of the new external work will be necessary. A few more years would put the surface of the Tower in a far worses state than it is now. I should carefully save and reuse every old moulding and surface stone which is at all likely to last, even though it may be in some respect in an imperfect state.” (50)
