Down in the valley of Hohr there was little or no wind, which greatly facilitated the carrying out of our rash venture.
The great bag, almost as large as the room in which we had been confined, bellied above us. It strained upon its guy ropes in its impatience to be aloft until I wondered that they held, and then I gave the word.
Simultaneously Nur An slipped his knot and I severed the rope upon the opposite side. Freed, the great bag leaped aloft, snapping us in its wake. It shot upward with a velocity that was astounding until the valley of Hohr was but a little hollow in the surface of the great world that lay below us.
Presently a wind caught us and you may be assured that we gave thanks to our ancestors as we realized that we were at last drifting from above the cruel city of Ghasta. The wind increased until it was blowing rapidly in a northeasterly direction, but little did we care where it wafted us as long as it took us away from the river Syl and the valley of Hohr.
After we had passed beyond the crater of the ancient volcano, which formed the bed of the valley in which lay somber Ghasta, we saw below us, in the moonlight, a rough volcanic country that presented a weird and impressive appearance of unreality; deep chasms and tumbled piles of basalt seemed to present an unsurmountable barrier to man, which may explain why in this remote and desolate corner of Barsoom the valley of Hohr had lain for countless ages undiscovered.
The wind increased. Floating at a great altitude we were being carried at considerable speed, yet I could see that we were very slowly falling as the hot air within our bag cooled. How much longer it would keep us up I could not guess, but I hoped it would bear us at least beyond the uninviting terrain beneath us.
With the coming of dawn we were floating but a few hundred feet above the ground; the volcanic country was far behind us and as far as we could see stretched lovely, rolling hills, sparsely timbered with the drought resisting skeel upon which it has been said the civilization of Barsoom has been erected.
As we topped a low hill, passing over it by a scant fifty sofads, we saw below us a building of gleaming white. Like all the cities and isolated buildings of Barsoom, it was surrounded by a lofty wall, but in other respects it differed materially from the usual Barsoomian type of architecture. The edifice, which was made up of a number of buildings, was not surmounted by the usual towers, domes and minarets that mark all Barsoomian cities and which only in recent ages have been giving away slowly to the flat landing stages of an aerial world. The structure below us was composed of a number of flat roofed buildings of various heights, none of which, however, appeared to rise over four levels. Between the buildings and the outer walls and in several open courts between the buildings, there was a profusion of trees and shrubbery with scarlet sward and well kept paths. It was, in fact, a striking and beautiful sight, yet having so recently been lured to near destruction by the beauties of Hohr and the engaging allurements of her beautiful women, we had no mind to be deceived again by external appearances. We would float over the palace of enchantment and take our chances in the open country beyond.
But fate willed otherwise. The wind had abated; we were dropping rapidly; beneath us we saw people in the garden of the building and simultaneously, as they discovered us, it was evident that they were filled with consternation. They hastened quickly to the nearest entrances and there was not a human being in sight when we finally came to rest upon the roof of one of the taller sections of the structure.
As we extricated ourselves from the loops in which we had been sitting, the great bag, relieved of our weight, rose quickly into the air for a short distance, turned completely over and dropped to the ground just beyond the outer wall. It had served us well and now it seemed like a living thing that had given up its life for our salvation.
