Oh, and, not to complain, as this kind of stuff happens all the time and is admirably rare in your document, but since you did ask: I found a typo (or a scan-o):
"Such a flame as that in the monk’s eye[,] though it had wandered in obscure places since, and had shone upon the barren hill side and among the stones and the stunted little trees[,] had been lit once at the original hearth; and doubtless it will
bum on still in the head of monk or peasant when more ages are passed than the brain can number."
I am pretty sure it should be "burn".
