I came to the edge of my hill and looked down into a cup of a valley, quite a little valley with the green waves towering on every side of it.

Through the mist there shimmered below me a blue lake.

I was puzzled--there was no water here that I knew, but by this time the Forest has so bewitched my senses that I'm ready to believe anything of it.

There it was, anyway, a blue lake, shifting a little under gold haze.

I climbed down the hill a yard or two and then you can believe that I jumped! My blue lake was Austrian prisoners, nothing more nor less! Has any one quite seen them like that before, I wonder, and isn't this Forest really the old witch's forest, able to do what it pleases with anything?
There they were, hundreds of them, covering the whole floor of the little valley.
