At this juncture Goliba joined us, and urging me not to speak in English lest the strange language might be overheard, we walked together for about three-quarters of an hour through thoroughfares so wide and well built that they would have been termed magnificent if constructed in any European city. Then we crossed a large square where a great fountain shooting up a hundred feet fell into its bowl, green with water-plants and white with flowers, and afterwards traversed a maze of narrower streets, now silent and deserted, where dwelt the workmen. Suddenly Goliba halted before an arched door, and directing us to imitate him, knelt and touched the door-step with his forehead, then passed in. We followed into a place that was strange to even Omar himself, who was scarce able to suppress an exclamation of astonishment. It was a small chamber, lit by a single flickering oil lamp of similar shape to those so often found amid the traces of the Roman occupation of England, while around were stone benches built into the wall. Walking to the opposite side of the narrow, prison-like place, we saw before us an arch with an impenetrable blackness beyond. Before this arch stood a kind of frame made of iron resting on either side upon steel ropes raised slightly from the ground. Following Goliba's example, we got upon it, crouching in a kneeling position in the same manner as himself. "Thou wilt find handles, wherewith to steady thyself," he cried to me. "Have a care that thou art not thrown off." I groped with my companions, and we found the handles of which he had spoken. Then, when all was ready, the grave-faced sage raised some lever or another, and we shot away down, down, down into space with such fearful velocity that the wind whistled about our ears, our white robes fluttered, and our breath seemed taken away. The sensation was awful. In utter darkness we were whirled along we knew not whither, until suddenly the car whereon we travelled gave an unexpected lurch, as a corner was turned, nearly precipitating all of us into the darkness beneath, and then continued its downward course with increased speed, until sparks flew from beneath us like flecks of fire from a blacksmith's forge, and in our breasts was a tightness that became more painful every moment. It seemed as though we were descending to some deep, airless region, for I could not breathe; the atmosphere felt damp and warm, and the velocity with which we travelled was becoming greater the deeper into the heart of the earth we went. "What is this place?" I heard Omar ask. "I know it not." "Be patient, O Prince, and thou shalt witness that which must astound thee," old Goliba shouted, his squeaky voice being just audible above the loud hissing as our car flew along the twisted strands of steel.
