We noticed that the newcomer was much less in height than were the Dwellers, either man or woman, that we had observed previously, and from this, and other youthful indications, it was not difficult to understand that we were watching a youth who had not yet gained his full stature. The sleeping figure did not stir, nor did he address himself to her, and I suppose that he would have gone on to the library to which the book was to be returned (for we had been right in this supposition, as the event proved, excepting only that it was the work of a subordinate, and not of the Librarian herself), but that, as he turned to leave the chamber, he was confronted by another youth, of his own age, who came from the opposite direction, and with an appearance of haste and excitement, such as I had not observed among these people previously. He commenced speaking immediately, and, as he did so, the Librarian arose from her couch so instantly and so quietly as to lead me to wonder whether she had been asleep at all. The messenger assailed her mind as she rose with a pressure of thought of which I could feel the impact, though I could not interpret it clearly, and appeared to be unable to avoid supplementing it with a useless triplication of speech and gesture. His auditor surveyed his excitement with a cool detachment which emphasised the millenniums of years that divided them. When he had finished, she took back the book from his waiting companion, and gave it an obviously quieter and briefer narrative. Then she lay down again, while the two youths left the chamber together, taking the book with them. It was doubtless their excited condition that caused them to move so rapidly that we had to quicken to a run to keep within sound of their footsteps. They led us back to the end of the passage, and then along the curving way, till we came to the next of the dark openings,--the one that led directly opposite to that by which we had entered beneath the temple. We followed them along it for about a quarter of a mile, finding it was in all respects alike to the other, being entirely dark, but having similar scenes developing within its walls continually. Had I been alone, I think that I could hardly have controlled my curiosity concerning some of them,--for I kept sufficiently close to the wall to observe them as we hurried past,--but I was too conscious of the useless folly of lingering to make such a suggestion to my companion. I had short glimpses of a score of scenes which I had no time to consider, and which left no clear impression, but of a bewildering variety of landscapes, and once of a tossing windswept sea, beneath a clouded moon. I caught no sight of human life, except once only, when I thought there was a distant string of horsemen trailing wearily along a muddy trampled road, but the scene was obscured by a storm of hail, and before I could be sure of what I had seen, it had been left behind.
