“Behold the balance of the World, you miserable, doubting men, and behold me change its path—turning it as the steersman turns a ship!”

Then he made certain signs to Yva, who in obedience to them approached the porthole or search-light to which she did something that I could not distinguish. The effect was to make the beam of light much stronger and sharper, also to shift it on to the point or foot of the spinning mountain and, by an aiming of the lens from time to time, to keep it there.

This went on for a while, since the dreadful thing did not travel fast notwithstanding the frightful speed of its revolutions. I should doubt indeed if it advanced more quickly than a man could walk; at any rate so it seemed to us. But we had no means of judging its real rate of progress whereof we knew as little as we did of the course it followed in the bowels of the earth. Perhaps that was spiral, from the world’s deep heart upwards, and this was the highest point it reached. Or perhaps it remained stationary, but still spinning, for scores or hundreds of years in some central powerhouse of its own, whence, in obedience to unknown laws, from time to time it made these terrific journeys.

No one knows, unless perhaps Oro did, in which case he kept the information to himself, and no one will ever know. At any rate there it was, travelling towards us on its giant butt, the peg of the top as it were, which, hidden in a cloud of friction-born sparks that enveloped it like the cup of a curving flower of fire, whirled round and round at an infinite speed. It was on this flaming flower that the search-light played steadily, doubtless that Oro might mark and measure its monstrous progress.

“He is going to try to send the thing down the right-hand path,” I shouted into Bickley’s ear.

“Can’t be done! Nothing can shift a travelling weight of tens of millions of tons one inch,” Bickley roared back, trying to look confident.

Clearly, however, Yva thought that it could be done, for of a sudden she cast down her shield and, throwing herself upon her knees, stretched out her hands in supplication to her father. I understood, as did we all, that she was imploring him to abandon his hellish purpose. He glared at her and shook his head. Then, as she still went on praying, he struck her across the face with his hand and pushed her to her feet again. My blood boiled as I saw it and I think I should have sprung at him, had not Bickley caught hold of me, shouting, “Don’t, or he will kill her and us too.”

Yva lifted her shield and returned to her station, and in the blue discharges which now flashed almost continuously, and the phosphorescent glare of the advancing mountain, I saw that though her beautiful face worked beneath the pain of the blow, her eyes remained serene and purposeful. Even then I wondered—what was the purpose shining through them. Also I wondered if I was about to be called upon to make that sacrifice of which she had spoken, and if so, how. Of one thing I was determined—that if the call came it should not find me deaf. Yet all the while I was horribly afraid.

At another sign from Oro, Yva did something more to the lens—again, being alongside of her, I could not see what it was. The beam of light shifted and wandered till, far away, it fell exactly upon that spot where the rock began to rise into the ridge which separated the two grooves or roads and ended in the razor-edged cliff. Moreover I observed that Oro, who left it the last of us, had either placed something white to mark this first infinitesimal bulging of the floor of the groove, or had smeared it with chalk or shining pigment. I observed also what I had not been able to see before, that a thin white line ran across the floor, no doubt to give the precise direction of this painted rise of rock, and that the glare of the search-light now lay exactly over that line.

The monstrous, flaming gyroscope fashioned in Nature’s workshop, for such without doubt it was, was drawing near, emitting as it came a tumult of sounds which, with the echoes that they caused, almost over-whelmed our senses. Poor little Tommy, already cowed, although he was a bold-natured beast, broke down entirely, and I could see from his open mouth that he was howling with terror. He stared about him, then ran to Yva and pawed at her, evidently asking to be taken into her arms. She thrust him away, almost fiercely, and made signs to me to lift him up and hold him beneath my shield. This I did, reflecting sadly that if I was to be sacrificed, Tommy must share my fate. I even thought of passing him on to Bickley, but had no time. Indeed I could not attract his attention, for Bickley was staring with all his eyes at the nightmare-like spectacle which was in progress about us. Indeed no nightmare, no wild imagination of which the mind of man is capable, could rival the aspect of its stupendous facts.
