A spur of the whitened steep on which the convent was founded, arising some twenty feet above the body of the mass of rock, was imbedded in the darkened wall of the tower, with its summit extending in a platform some three feet square, toppling over the dark abyss below.

Level as the sun-dial and smooth as polished steel, the summit of the rock, projecting from the tower, might scarce afford a resting place for footstep of human thing. In silence and in awe the Duke gazed around.

Above was the moonlit sky, below far, far below, a hundred fathoms down sunk the dark and shadowy abyss, separated from the waters of the lake by a ridge of rocks, that arose along the shores of the mountain tarn, overlooking the sullen blackness of the impenetrable void, on one side, while on the other towered and frowned above the walls of the gloomy convent.

Gazing hurriedly around, the Duke beheld the walls of the Monastery, extending on either side of the tower, in whose stones the platform-rock was imbedded, all smooth, even and moss-grown; at his back leading into the cell of St. Areline, was the secret door, fashioned in complete resemblance to the wall around, fast closed and secured, while high overhead arose the dark and frowning fabric of the tower, its rugged outline, rising like a thing of omen into the dim blue of the midnight sky.

CHAPTER THE SIXTH.
THE WATCH BESIDE THE DEAD.

“All—all is dark!” the voice broke wild and whisperingly through the midnight gloom of the place—“I have been dreaming—ah, me—a sad and darksome dream! Methought Adrian lay cold and dead in my arms, while my hand was entwined in the locks of his clustering hair, as they fell over his lifeless face. It was a dream, a fearful dream—yet—mother of heaven—do I still dream, or is this darkness real?”

She extended her hands, she passed them hurriedly along the floor, where her form lay prostrate, and as she thus wildly sought to grasp the form so lately reposing in her arms, she exclaimed with a murmured shriek—
