impossible to say to which of these we owed our salvation. Also, on the day before we started back to Loo, we made a further examination of the wonders of the stalactite cave, and, drawn by a kind of restless feeling, even penetrated once more into the Chamber of the Dead. Passing beneath the spear of the White Death we gazed, with sensations which it would be quite impossible for me to describe, at the mass of rock that had shut us off from escape, thinking the while of the priceless treasures beyond, of the mysterious old hag whose flattened fragments lay crushed beneath it, and of the fair girl of whose tomb it was the portal.
