"But is it not incredible that a people of so peaceable a disposition should be seized with such murderous instincts when driven out of their senses by the effect of the rays?"
"No, it does not seem so to me. You know the general tendency of sudden madness, which usually produces a complete reversal of the ordinary instincts of the demented persons, making them dangerous to their dearest friends. But why talk longer of this? It is too painful—too overwhelming. What can man do against the great forces of Nature? At this moment I solemnly declare to you that I regret that I ever entered upon this expedition."
While we had been talking, the car had receded to a great distance from the city, and now all but the tops of a few of the airy pinnacles were lost to our sight forever. But as we gazed, straining our sight for a last look, we perceived a familiar flickering of prismatic lightning on the horizon. We glanced at each other meaningly. It was the color speech again. But, oh, what must be the burden of their communications now! Suddenly, Edmund, whose eyes were fixed with intensity upon the scene, remarked, half shuddering:
"It is the great Paean."
Seized with curiosity, I pressed the magic box to my ear, and faintly there echoed in my brain a few disconnected strains of that solemn music. But now, more than ever, it was insufferable to me, and I dropped the box with a crash.
As Edmund recovered his strength he once more took charge of the car, and in a little while he had risen to a great height in order to take advantage of the easier going in the lighter atmosphere above. Thus we ran on for several hours until we began to catch sight of the sea, which was soon beneath us, while far ahead we saw the tumbling clouds marking the location of the belt of tempests behind which we knew lay the range of the crystal mountains. At length we issued from beneath the cloud dome, and then we saw the sun again, and the storms whipping the waters, whose waves occasionally flashed up at us through rifts in the streaming clouds beneath. And at last the icy peaks began to glitter on the horizon, and we knew that we were nearing the world of eternal night and frost. It was with strange feelings that we once more beheld the crystal mountains, for our minds were filled with the recollection of the scenes that had occurred among them when we were helpless in the grasp of their tempests. But now there was a certain exhilaration in the thought that this time we could safely sail over their summits. As we passed over them we looked eagerly for landmarks that might show where our former passage had occurred, and as Edmund purposely dropped as close to their summits as it was safe to go, I at last believed that I recognized the mighty peak of rainbows that had so nearly wrecked us.
When we had left the mountains behind and entered into the region of night, I asked Edmund how he would proceed in order to find the location of the caverns.
"I shall go by the stars," he said. "I noted the bearing of the place, and I have no doubt that I can find it again."
