Hovering over the crater, which we found just as we expected, we looked down into a black abyss, so vast and awful, that we had no inclination to investigate it, although it was large enough for us to have descended bodily with the air ship. There was no smoke, nor were any sulphurous fumes emitted. Evidently the volcano had been extinct for ages; and we passed rapidly on upon our north bound course, glad enough to have dry land under us once again, and to descend to a lower and warmer level. We were soon down among the foothills, and traversing a well timbered country, rising from time to time to clear the elevations encountered. The panorama that now stretched away before us was one of ravishing beauty, and we took our places on deck with lighted cigars to enjoy it. I suggested that we name the new land "Torrenzia," but Torrence only declared that while people might call it what they pleased, the credit of the new world must go to the man who had first seen it.

"You seem to think there is only one scrap of a continent here," he said, "and Torrenzia may do well enough for one; but remember it is a new world we have entered; and if I am not greatly mistaken we shall find it studded with civilizations equal to any we know. Certainly you are dense, Gurthrie, and stupid to a degree, not to have guessed by this time where we are!"

I did not answer; in fact I was provoked that he should be so secretive with the information he possessed. I confessed to my bewilderment at what we saw but was still in the dark as to the truth.

We now ran rapidly forward over a picturesque country, and through an atmosphere not only temperate but exhilarating. About a hundred miles inland the timber and water courses were less prolific, and fifty miles farther we merged upon a great, treeless plain, covered with short tussocky grass, sand, and rocks. At intervals were to be seen the bones of animals bleaching where they had fallen, the entire skeletons being generally intact. More than once we descended to the ground to examine them, but could not decide whether they were buffalo or some other creature. What surprised us most was the fact that there appeared to be no living ones. But we did not waste our time upon this arid plain, fearing to run short of water, and being particularly anxious to discover if our new world was inhabited. As we sat on deck smoking our cigars, rushing into the gentle breeze ahead, we felt like monarchs, or rather god-like creatures, who owned and ruled a world from above.

We had little time for sleep, our excitement being intense, and the short intervals we spared for an occasional nap, were taken alternately, the one remaining on deck promising the other to wake him as soon as anything of special interest occurred. I had just come above after one of these short siestas and joining my brother observed him looking with unusual interest through the glass at something below.

"What is it now?" I called, leaning over the rail.

At a glance I saw that the nature of the country had changed. No more skeletons; no more sand and rocks, or arid desert, but a great sheet of water lay to our right, while below and beyond were trees and fields, which looked as if they were cultivated; and here and there, at intervals of a mile or two, were undoubtedly the walls of human habitations. I do not say they were houses, for houses have roofs, whereas these edifices were roofless.

"I am sure I have discovered houses," said Torrence; "and I am trying to see if there are any people!"

I took the glass from his hand.

"There is no doubt about it," I exclaimed; "and what is more, they do not appear to be ruins, but houses in perfect repair, judging from their similarity and the condition of the grounds around them. But what kind of climate must these people enjoy to require no roofs? Certainly it can never rain!"
