"The cylinder is now gathering cosmic rays from an immense area of space," he said, "and those concentrated rays are falling through that disk into the cube's interior. To cut off the rays it is necessary only to open this switch." He reached to open the switch, the light died.
THE MAN WHO EVOLVED
Quickly, while we stared, he removed his clothing, donning in place of it a loose white running suit.
"I will want to observe the changes of my own body as much as possible," he explained. "Now, I will stand inside the cube and you will turn on the rays and let them play upon me for fifteen minutes. Roughly, that should represent a period of some fifty million years of future evolutionary change. At the end of fifteen minutes you will turn the rays off and we will be able to observe what changes they have caused. We will then resume the process, going forward by fifteen-minute or rather fifty-million-year periods."
"But where will it stop--where will we quit the process?" Dutton asked.
Pollard shrugged. "We'll stop where evolution stops, that is, where the rays no longer affect me. You know, biologists have often wondered what the last change or final development of man will be, the last mutation. Well, we are going to see tonight what it will be."
He stepped toward the cube and then paused, went to a desk and brought from it a sealed envelope he handed to me.
"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.
"You see? It worked as I knew it would work! I'm fifty million years ahead of the rest of humanity in evolutionary development!"
"Pollard!" My lips moved with difficulty. "Pollard, this is terrible--this change--"
His radiant eyes flashed. "Terrible? It's wonderful! Do you two realize what I now am, can you realize it? This body of mine is the kind of body all men will have in fifty million years, and the brain inside it is a brain fifty million years ahead of yours in development!"
he swept his hand about. "Why, all this laboratory and former work of mine seems infinitely petty, childish, to me! The problems that I worked on for years I could solve now in minutes. I could do more for mankind now than all the men now living could do together!"
"Then you're going to stop at this stage?" Dutton cried eagerly. "You're not going further with this?"
"Of course I am! If fifty million years' development makes this much change in man, what will a hundred million years, two hundred million make? I'm going to find that out."
I grasped his hand. "Pollard, listen to me! Your experiment has succeeded, has fulfilled your wildest dreams. Stop it now! Think what you can accomplish, man! I know your ambition has always been to be one of humanity's great benefactors--by stopping here you can be the greatest! You can be a living proof to mankind of what your process can make it, and with that proof before it all humanity will be eager to become the same as you!"
He freed himself from my grasp. "No, Arthur--I have gone part of the way into humanity's future and I'm going on."
He stepped back into the chamber, while Dutton and I stared helplessly. It seemed half a dream, the laboratory, the cubical chamber, the godlike figure inside that was and still was not Pollard.
"Turn on the rays, and let them play for fifteen minutes more," he was directing. "It will project me ahead another fifty million years."
His eyes and voice were imperative, and I glanced at my watch, and snicked over the switch. Again the cylinder broke into light, again the shaft of force shot down into the cube to hide Pollard's splendid figure.
Dutton and I waited with feverish intensity in the next minutes. Pollard was standing still beneath the broad shaft of force, and so was hidden in it from our eyes. What would its lifting disclose? Would he have changed still more, into some giant form, or would he be the same, having already reached humanity's highest possible development?
When I shut off the mechanism at the end of the appointed period, Dutton and I received a shock. For again Pollard had changed!
He was no longer the radiant, physically perfect figure of the first metamorphosis. His body instead seemed to have grown thin and shrivelled, the outlines of bones visible through its flesh. His body, indeed, seemed to have lost half its bulk and many inches of stature and breadth, but these were compensated for by the change in his head.
For the head supported by this weak body was an immense, bulging balloon that measured fully eighteen inches from brow to back! It was almost entirely hairless, its great mass balanced precariously upon his slender shoulders and neck. And his face too was changed greatly, the eyes larger and the mouth smaller, the ears seeming? smaller also. The great bulging forehead dominated the face.
Could this be Pollard? His voice sounded thin and weak to our ears. I
"You are surprised to see me this time? Well, you see a man a hundred million years ahead of you in development. And I must confess that you appear to me as two brutish, hairy cave-men would appear to you."
"But Pollard, this is awful!" Dutton cried. "This change is more terrible than the first . . . if you had only stopped at the first . . ."
The eyes of the shrivelled, huge-headed figure in the cube fired with anger. "Stop at that first stage? I'm glad now that I didn't! The man I was fifteen minutes ago . . . fifty million years ago in development . . . seems now to me to have been half-animal! What was his big animal-like body beside my immense brain?" j
"You say that because in this change you're getting away from all human emotions and sentiments!" I burst. "Pollard, do you realize what you're doing? You're changing out of human semblance!"
"I realize it perfectly," he snapped, "and I see nothing to be deplored in the fact. It means that in a hundred million years man will be developing in brain-capacity and will care nothing for the development of body. To you two crude beings, of what is to me the past,: this seems terrible; but to me it is desirable and natural. Turn on the rays again!"
"Don't do it. Art!" cried Dutton. "This madness has gone far enough!"
Pollard's great eyes surveyed us with cold menace. "You will turn on the rays," his thin voice ordered deliberately. "If you do not, it will be but the work of a moment for me to annihilate both of you and go on with this alone."
"You'd kill us?" I said dumfoundedly. "We two, two of your best friends?"
His narrow mouth seemed to sneer. "Friends? I am millions of years past such irrational emotions as friendship. The only emotion you awaken in me is a contempt for your crudity. Turn on the rays!"
THE BRAIN MONSTER
His eyes blazed as he snapped the last order, and as though propelled by a force outside myself, I closed the switch.
The shaft of glowing force again hid him from our view.
Of our thoughts during the following quarter-hour I can say nothing, for both Dutton and I were so rigid with awe and horror as to make our minds chaotic. I shall never forget, though, that first moment after the time had passed and I had again switched off the mechanism.
The change had continued, and Pollard--I could not call him that in my own mind--stood in the cube-chamber as a shape the sight of which stunned our minds.
He had become simply a great head! A huge hairless head fully a yard in diameter, supported on tiny legs, the arms having dwindled to mere hands that projected just below the head! The eyes were enormous, saucer-like, but the ears were mere pin-holes at either side of the head, the nose and mouth being similar holes below the eyes!
He was stepping out of the chamber on his ridiculously little limbs, and as Dutton and I reeled back in unreasoning horror, his voice came to us as an almost inaudible piping. And it held pride!
"You tried to keep me from going on, and you see what I have become? To such as you, no doubt, I seem terrible, yet you two and all like you seem as low to me as the worms that crawl!"
"Good God, Pollard, you've made yourself a monster!" The words burst from me without thought.
His enormous eyes turned on me. "You call me Pollard, yet I am no more the Pollard you knew, and who entered that chamber first, than you are the ape of millions of years ago from whom you sprang! And all mankind is like you two! Well, they will all learn the powers of one who is a hundred and fifty million years in advance of them!"
"What do you mean?" Dutton exclaimed.
"I mean that with the colossal brain I have I will master without a struggle this man-swarming planet, and make it a huge laboratory in which to pursue the experiments that please me."
"But Pollard--remember why you started this!" I cried. "To go ahead and chart the path of future evolution for humanity--to benefit humanity and not to rule it!"
The great head's enormous eyes did not change. "I remember that the creature Pollard that I was until tonight had such foolish ambitions, yes. It would stir mirth now, if I could feel such an emotion, To benefit humanity? Do you men dream of benefiting the animal you rule over? I would no sooner think of working for the benefit you humans!
"Do you two yet realize that I am so far ahead of you in brain power now as you are ahead of the beasts that perish? Look a this . . ." I
He had climbed onto a chair beside one of the laboratory table was reaching among the retorts and apparatus there. Swiftly he poured several compounds into a lead mortar, added others, poured upon the mixed contents another mixture made as swiftly.
There was a puff of intense green smoke from the mortar instantly, and then the great head--I can only call him that--turned the mortar upside down. A lump of shining mottled metal fell out and we gasped as we recognized the yellow sheen of pure gold, made in a moment, apparently, by a mixture of common compounds!
"You see?" the grotesque figure was asking. "What is the tranformation of elements to a mind like mine? You two cannot even realize the scope of my intelligence!
"I can destroy all life on this earth from this room, if I desire. I can construct a telescope that will allow me to look on the planets the farthest galaxies! I can send my mind forth to make contact with other minds without the slightest material connection. And you think it terrible that I should rule your race! I will not rule them, I will own them and this planet as you might own a farm and animals!"
"You couldn't!" I cried. "Pollard, if there is anything of Pollard left in you, give up that thought! We'll kill you ourselves before we'll let you start a monstrous rule of men!"
"We will--by God, we will!" Dutton cried, his face twitching.
We had started desperately forward toward the great head but stopped suddenly in our tracks as his great eyes met ours. I found myself walking backward to where I had stood, walking back and Dutton with me, like two automatons.
"So you two would try to kill me?" queried the head that had been Pollard. "Why, I could direct you without a word to kill yourselves and you'd do so in an instant! What chance has your puny will and brain against mine? And what chance will all the force of men have against me when a glance from me will make them puppets of my will?"
A desperate inspiration flashed through my brain. "Pollard, wait!" I exclaimed. "You were going on with the process, with the rays! If you stop here you'll not know what changes lie beyond your present form!"
He seemed to consider. "That is true," he admitted, "and though it seems impossible to me that by going on I can attain to greater intelligence than I now have, I want to find out for certain."
"Then you'll go under the rays for another fifteen minutes?" I asked quickly.
"I will," he answered, "but lest you harbor any foolish ideas, you may know that even inside the chamber I will be able to read your thoughts and can kill both of you before you can make a move to harm me."
He stepped up into the chamber again, and as I reached for the switch, Dutton trembling beside me, we glimpsed for a moment the huge head before the down-smiting white force hid it from our sight.
The minutes of this period seemed dragging even more slowly than before. It seemed hours before I reached at last to snap off the lays. We gazed into the chamber, shaking.
At first glance the great head inside seemed unchanged, but then we saw that it had changed, and greatly. Instead of being a skin-covered head with at least rudimentary arms and legs, it was now a great gray head-like shape of even greater size, supported by two gray muscular tentacles. The surface of this gray head-thing was wrinkled and folded, and its only features were two eyes as small as our own.
"Oh my God!" quaked Dutton. "He's changing from a head into a brain--he's losing all human appearance!"
Into our minds came a thought from the gray head-thing before us, a thought as clear as though spoken. "You have guessed it, for even my former head-body is disappearing, all atrophying except the brain. I am become a walking, seeing brain. As I am so all of your race will be in two hundred million years, gradually losing more and more of their atrophied bodies and developing more and more their great brains."
His eyes seemed to read us. "You need not fear now the things I threatened in my last stage of development. My mind, grown infinitely greater, would no more now want to rule you men and your little planet than you would want to rule an anthill and its inhabitants!
My mind, gone fifty million years further ahead in development, can soar out now to vistas of power and knowledge unimagined by me in that last stage, and unimaginable to you."
"Great God, Pollard!" I cried. "What have you become?"
"Pollard?" Dutton was laughing hysterically. "You call that thing Pollard? Why, we had dinner with Pollard three hours ago--he was a human being, and not a thing like this!"
"I have become what all men will become in time," the thing's thought answered me. "I have gone this far along the road of man's future evolution, and am going on to the end of that road, am going to attain the development that the last mutation possible will give me!"
"Turn on the rays," his thought continued. "I think that I must be approaching now the last possible mutation."
I snapped over the switch again and the white shaft of the concentrated rays veiled from us the great gray shape. I felt my own mind giving beneath the strain of horror of the last hour, and Dutton was still half-hysterical.
The humming and crackling of the great apparatus seemed thunderous to my ears as the minutes passed. With every nerve keyed to highest tension, I threw open the switch at last. The rays ceased, and the figure in the chamber was again revealed.
Dutton began to laugh shrilly, and then abruptly was sobbing. I do not know whether I was doing the same, though I have a dim memory of mouthing incoherent things as my eyes took in the shape in the chamber.
It was a great brain! A gray limp mass four feet across, it lay in the chamber, its surface ridged and wrinkled by innumerable fine convolutions. It had no features or limbs of any kind in its gray mass. It was simply a huge brain whose only visible sign of life was its slow twitching movement.
From it thoughts beat strongly into our own horror-weighted brains.
"You see me now, a great brain only, just as all men will be far in the future. Yes, you might have known, I might have known, when I was like you, that this would be the course of human evolution, that the brain that alone gives man dominance would develop and the body that hampers that brain would atrophy until he would have developed into pure brain as I now am!
"I have no features, no senses that I could describe to you, yet can realize the universe infinitely better than you can with your elementary senses. I am aware of planes of existence you cannot imagine. I can feed myself with pure energy without the need of a cumbersome body, to transform it, and I can move and act, despite my lack of limbs, by means and with a speed and power utterly beyond your comprehension.
