"This is just in case something happens to me of a fatal nature," he said. "It contains an attestation signed by myself that you two are in no way responsible for what I am undertaking."
"Pollard, give up this unholy business!" I cried, clutching his arm. "It's not too late, and this whole thing seems ghastly to me!"
"I'm afraid it is too late," he smiled. "If I backed out now I'd be ashamed to look in a mirror hereafter. And no explorer was ever more eager than I am to start down the path of man's future evolution!"
He stepped up into the cube, standing directly beneath the disk in its ceiling. He motioned imperatively, and like an automaton I closed the door and then threw the switch.
The cylinder broke again into glowing white light, and as the shafts of glowing white force shot down from the disk in the cube's ceiling upon Pollard, we glimpsed his whole body writhing as though beneath a terrifically concentrated electrical force. The shaft of glowing emanations almost hid him from our view. I knew that the cosmic rays in themselves were invisible but guessed that the light of the cylinder and shaft was in some way a transformation of part of the rays into visible light. '
Dutton and I stared with beating hearts into the cubical chamber, having but fleeting glimpses of Pollard's form. My watch was in one hand, the other hand on the switch. The fifteen minutes that followed seemed to me to pass with the slowness of fifteen eternities. Neither of us spoke and the only sounds were the hum of the generators and the crackling of the cylinder that from the far spaces was I gathering and concentrating the rays of evolution.
At last the watch's hand marked the quarter-hour and I snapped I off the switch, the light of the cylinder and inside the cube dying. Exclamations burst from us both.
Pollard stood inside the cube, staggering as though still dazed by the impact of the experience, but he was not the Pollard who had entered the chamber! He was transfigured, godlike! His body had literally expanded into a great figure of such physical power and beauty as we had not imagined could exist! He was many inches taller and broader, his skin a clear pink, every limb and muscle molded as though by some master sculptor.
The greatest change, though, was in his face. Pollard's homely, good-humored features were gone, replaced by a face whose perfectly-cut features held the stamp of immense intellectual power that shone almost overpoweringly from the dear dark eyes. It was not Pollard who stood before us, I told myself, but a being as far above us as the most advanced man of today is above the troglodyte!
He was stepping out of the cube and his voice reached our ears, clear and bell-like, triumphant.
