Franz had remained for nearly a quarter of an hour perfectly hidden by the shadow of the vast column at whose base he had found a resting - place, and from whence his eyes followed the motions of albert and his guides, who, holding torches in their hands, had emerged from a vomitarium at the opposite extremity of the colosseum, and then again disappeared down the steps conducting to the seats reserved for the vestal virgins, resembling, as they glided along, some restless shades following the flickering glare of so many ignes - fatui. all at once his ear caught a sound resembling that of a stone rolling down the staircase opposite the one by which he had himself ascended. there was nothing remarkable in the circumstance of a fragment of granite giving way and falling heavily below ; but it seemed to him that the substance that fell gave way beneath the pressure of a foot, and also that some one, who endeavored as much as possible to prevent his footsteps from being heard, was approaching the spot where he sat
