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."
