In a little time he joined me; head down, silent, he strode along beside me, utterly dejected.
A hundred more yards and we turned. Ruth was still standing on the threshold of the house of mystery, watching us. She waved her hands, flitted in, was hidden from us. And Drake still silent, we pushed on.
The walls of the gateway were close. The sparse vegetation along the base of the cliffs had ceased; the roadway itself had merged into the smooth, bare floor of the canyon. From vertical edge to vertical edge of the rocky portal stretched a curtain of shimmering mist. As we drew nearer we saw that this was motionless, and less like vapor of water than vapor of light; it streamed in oddly fixed lines like atoms of crystals in a still solution. Drake thrust an arm within it, waved it; the mist did not move. It seemed instead to interpenetrate the arm—as though bone and flesh were spectral, without power to dislodge the shining particles from position.
We passed within it—side by side.
Instantly I knew that whatever these veils were, they were not moisture. The air we breathed was dry, electric. I was sensible of a decided stimulation, a pleasant tingling along every nerve, a gaiety almost light-headed. We could see each other quite plainly, the rocky floor on which we trod as well. Within this vapor of light there was no ghost of sound; it was utterly empty of it. I saw Drake turn to me, his mouth open in a laugh, his lips move in speech—and although he bent close to my ear, I heard nothing. He frowned, puzzled, and walked on.
Abruptly we stepped into an opening, a pocket of clear air. Our ears were filled with a high, shrill humming as unpleasantly vibrant as the shriek of a sand blast. Six feet to our right was the edge of the ledge on which we stood; beyond it was a sheer drop into space. A shaft piercing down into the void and walled with the mists.
But it was not that shaft that made us clutch each other. No! It was that through it uprose a colossal column of the cubes. It stood a hundred feet from us. Its top was another hundred feet above the level of our ledge and its length vanished in the depths.
And its head was a gigantic spinning wheel, yards in thickness, tapering at its point of contact with the cliff wall into a diameter half that of the side closest the column, gleaming with flashes of green flame and grinding with tremendous speed at the face of the rock.
Over it, attached to the cliff, was a great vizored hood of some pale yellow metal, and it was this shelter that cutting off the vaporous light like an enormous umbrella made the pocket of clarity in which we stood, the shaft up which sprang the pillar.
All along the length of that column as far as we could see the myriad tiny eyes of the Metal People shone out upon us, not twinkling mischievously, but—grotesque as this may seem, I cannot help it—wide with surprise.
