I think I fired at the shield. And Alan leapt aside. I heard the faint hiss of his Essen. And his choked, horrified voice:
"George--come back! Run! Don't fall! Don't!"
I crumpled; slid into blackness. And it seemed, as I went down, that Alan's inert body was falling on top of me....
I recovered consciousness after a nameless interval, a phantasmagoria of wild, drugged dreams. My senses came slowly. At first, there were dim muffled voices and the tread of footsteps. Then I knew that I was lying on the ground, and that I was indoors. It was warm. My overcoat was off. Then I realized that I was bound and gagged.
I opened my eyes. Alan was lying inert beside me, roped and with a black gag around his face and in his mouth. We were in a huge dim open space. Presently, as my vision cleared, I saw that the dome was overhead. This was a circular, hundred-foot-wide room. It was dimly lighted. The figures of men were moving about, their great misshapen shadows shifting with them. Twenty feet from me there was a pile of golden rock--chunks of gold the size of a man's fist, or his head, and larger, heaped loosely into a mound ten feet high.
Beyond this pile of ore, near the center of the room, twenty feet above the concrete floor, there was a large hanging electrolier. It cast a circular glow downward. Under it I saw a low platform raised a foot or two above the ground. A giant electro-microscope was hung with its twenty-foot cylinder above the platform. Its intensification tubes were glowing in a dim phosphorescent row on a nearby bracket. A man sat in a chair on the platform at the microscope's eyepiece.
I saw all this with a brief glance, then my attention went to a white stone slab under the giant lense. It rested on the platform floor, a two-foot-square surface of smooth white stone like marble. A little roped railing a few inches high fenced it. And in its center lay a fragment of golden quartz the size of a walnut!
There was a movement across my line of vision. Two figures advanced. I recognized both of them. And I strained at my bonds; mouthed the gag with futile, horrified effort. I could no more than writhe; and I could not make a sound. I lay, after a moment exhausted, and stared with horror.
