Now the passage, though its entrance had been cunningly hidden by man’s artifice, was one of those veins in which the fiery blood of our mother, the Earth, had aforetime coursed. Long years had passed since it carried lava streams, but the air in it was still warm and sulphurous, and there was no inducement to linger in transit. I lit me a lamp which I found in an appointed niche, and walked briskly along my ways, coughing, and wishing heartily I had some of those simples which ease a throat that has a tendency to catarrh. But, alas! all that packet of drugs which were my sole spoil from the vice-royalty of Yucatan were lost in the sea-fight with Dason’s navy, and since landing in Atlantis there had been little enough time to think for the refinements of medicine. The network of earth-veins branched prodigiously, and if any but one of us Seven Priests had found a way into its recesses by chance, he would have perished hopelessly in the windings, or have fallen into one of those pits which lead to the boil below. But I carried the chart of the true course clearly in my head, remembering it from that old initiation of twenty years back, when, as an appointed viceroy, I was raised to the highest degree but one known to our Clan, and was given its secrets and working implements. The way was long, the floor was monstrous uneven, and the air, as I have said, bad; and I knew that day would be far advanced before the signs told me that I had passed beneath the walls, and was well within the precincts of the city. And here the vow of the Seven hampered my progress; for it is ordained that under no circumstances, whatever the stress, shall egress be made from this passage before mortal eye. One branch after another did I try, but always found loiterers near the exits. I had hoped to make my emergence by that path which came inside the royal pyramid. But there was no chance of coming up unobserved here; the place was humming like a hive. And so, too, with each of the five next outlets that I visited. The city was agog with some strange excitement. But I came at last to a temple of one of the lesser Gods, and stood behind the image for a while making observation. The place was empty; nay, from the dust which robed all the floors and the seats of the worshippers, it had been empty long enough; so I moved all that was needful, stepped out, and closed all entry behind me. A broom lay unnoticed on one of the pews, and with this I soon disguised all route of footmark, and took my way to the temple door. It was shut, and priest though I was, the secret of its opening was beyond me. Here was a pretty pass. No one but the attendant priests of the temple could move the mechanism which closed and opened the massive stone which filled the doorway; and if all had gone out to attend this spectacle, whatever it might be, that was stirring the city, why there I should be no nearer enlargement than before.
