The tale tells that in times long past there was a dwelling of men beside a great wood. Before it lay a plain, not very great, but which was, as it were, an isle in the sea of woodland, since even when you stood on the flat ground you could see trees everywhere in the offing, though as for hills, you could scarce say that there were any, - only swellings-up of the earth here and there, like the upheavings of the water that one sees at whiles going on amidst the eddies of a swift but deep stream.
