After London by Richard Jefferies

So far as this, all that I have stated has been clear, and there can be no doubt that what has been thus handed down from mouth to mouth is for the most part correct. When I pass from trees and animals to men, however, the thing is different, for nothing is certain and everything confused. None of the accounts agree, nor can they be altogether reconciled with present facts or with reasonable supposition; yet it is not so long since but a few memories, added one to the other, can bridge the time, and, though not many, there are some written notes still to be found. I must attribute the discrepancy to the wars and hatreds which sprang up and divided the people, so that one would not listen to what the others wished to say, and the truth was lost.

Besides which, in the conflagration which consumed the towns, most of the records were destroyed, and are no longer to be referred to. And it may be that even when they were proceeding, the causes of the change were not understood. Therefore, what I am now about to describe is not to be regarded as the ultimate truth, but as the nearest to which I could attain after comparing the various traditions. Some say, then, that the first beginning of the change was because the sea silted up the entrances to the ancient ports, and stopped the vast commerce which was once carried on. It is certainly true that many of the ports are silted up, and are now useless as such, but whether the silting up preceded the disappearance of the population, or whether the disappearance of the population, and the consequent neglect caused the silting, I cannot venture to positively assert.
