"Slowly, as befitted one of his years, he descended the ladder and reached the slimy steps below. This was ancient masonry, his torch told him; and upon the dripping walls he saw the unwholesome moss of centuries.

He had counted about thirty when a sound reached him very faintly; and after that he did not feel disposed to count any more." -- The Case of Charles Dexter Ward
