In the middle of the hall he paused and thought. A degree of hesitation appeared to come over him; and then, murmuring "It must be all nonsense; but, true or not, I have promised, and I will go," he walked forward to another door at the far end of the hall, much smaller than that by which he had entered. Apparently, it had not been opened for a long time, as a pile of dust lay thick, against it. There was no key in the lock, and it seemed fastened from the other side. After pushing it, however, to see if it would give way, the young man drew forth a key, saying to himself, "Perhaps this opens all," and applying it, after some examination of the key-hole, he turned it, and threw back the door. Then holding up the lamp ere he entered, he gazed into the space before him. It was a low narrow passage in the stone-work, with no windows, or even loopholes, perceptible; but yet the damp found its way in, for the walls were glistening all over with unwholesome slime. The pavement, too, if pavement indeed there was at all, was covered thickly with a coating of black mould, from which, every here and there, sprang up a crop of pale sickly fungi covered with noxious dew, spreading a sort of faint, unpleasant, odour around. So foul, and damp, and gloomy looked the place, that it evidently required an effort of resolution on the young man's part to enter; but after pausing for a moment he did so, and closed and locked the door behind him; then turning round, he looked on, still holding up the lamp, as if he expected to see some fearful object in the way: all was vacant, however, and as the faint rays of light dispersed the darkness, he could perceive another door at the end of the passage, some twenty yards in advance. It, when he reached it, was found unfastened, and on drawing it back--for it opened inwards--the top of a flight of stone steps was before him, descending, apparently, into a well.
