And on a point of land projecting from the bottom of that mighty wall I saw the château!

It could have been nothing else. It was a splendid building—not larger than the house of a country gentleman, perhaps, and made of hewn logs; but the rude splendour of it against that icy, rocky background transfixed me with wonder.

It was a rambling, straggling building, apparently constructed at different times; having two wings and a wide central hall, with odd projecting chambers, and it was hidden so cunningly away that it was visible from this side of the lake only from the point of the rocky precipice above on which I stood.

The château stood under the overhanging precipice in such a way that half the building was invisible even from here. It seemed to be set back into a hollow of the mountainside, which appeared every moment about to overwhelm it.

And now I perceived that the smooth slope on which I stood was a snow-covered glacier, a million tons of ice, pressing ever by its own weight toward the precipice, and carrying its débris of rocks and stones toward the waterfall that issued from it and poured in deafening clamour into the lake below.

Where the precipice projected the waterfall was split in two, and rushed down in twin streams, bubbling, tumbling, hissing, plunging into the lake, which whirled furiously around the spit of land on which the castle stood, clear of ice for a distance of a hundred feet from the shore, a foaming maelstrom in which no boat that was ever built could have endured an instant, but must have been twisted and flung back like the fantastically shaped ice pinnacles along the marge.

On each side of the château a cataract plunged, veiling itself in an opacity of mist, tinted with all the spectral hues by the rays of the westering sun. I could have flung a stone down, not on the château, but over it, into the boiling lake.

Why, that position was impregnable! Behind it the sheer precipice, up which not even a bird could walk; the impassable lake before it, and the torrent on either side!

But—how had M. Charles Duchaine gained entrance there?

There seemed to be no entrance. And yet the château stood before my eyes, no dream, but very real indeed. There was a small piece of enclosed land between its front and the lake, and within this I thought I could see dogs lying.
