the world he will conquer — came unseen when I refused my permission."
He was silent for a long time, pondering. Then he turned passionately to Northwood.
"John Northwood, kill me! I have brought a new horror into the world. From the unborn future, I have snatched a creature who has reached the Light too soon. Kill me!" He bowed his great, shaggy head.
"What do you mean, Dr. Mundson: that this Adam has arrived at a point in evolution beyond this age?"
"Yes. Think of it! I visioned god-like creatures with the souls of gods. But, Heaven help us, man always will be man; always will lust for conquest. You and I, Northwood, and all others are barbarians to Adam. He and his kind will do what men always do to barbarians—conquer and kill."
"Are there more like him?" Northwood struggled with a smile of unbelief.
"I don't know. I did not know that Adam had reached a point so near the ultimate. But you have seen. Already he is able to set aside what we call natural laws."
Northwood looked at the scientist closely. The man was surely mad—mad in this desert of white death.
"Come!" he said cheerfully. "Let's build an Eskimo snow house. We can live on penguins for days. And who knows what may rescue us?"
For three hours the two worked at cutting ice blocks. With snow for mortar, they built a crude shelter which enabled them to rest out of the cold breath of the spiral polar winds that blew from the south.
DR. MUNDSON was sitting at the door of their hut, moodily pulling at his strong, black pipe. As though a fit had seized him, he leaped up and let his pipe fall to the ice.
"Look!" he shouted. "The sun-ship!"
It seemed but a moment before the tiny speck on the horizon had swept overhead, a silver comet on the grayish-blue polar sky. In another moment it had swooped down, eaglewise, scarcely fifty feet from the ice hut.
Dr. Mundson and Northwood ran forward. From the metal sphere stepped the stranger of the Mad Hatter Club. His tall, straight form, erect and slim, swung toward them over the ice,
"Adam!" shouted Dr. Mundson. "What does this mean? How dare you!"
Adam's laugh was like the happy demonstration of a boy. "So? You think you still are master? You think I returned because I reverenced you yet?" Hate shot viciously through the freezing blue eyes. "You worm of the Black Age!"
Northwood shuddered. He had heard those strange words addressed to himself scarcely more than twelve hours ago.
Adam was still speaking: "With a thought I could annihilate you where you are standing. But I have use for you. Get in." He swept his hand to the sun-ship.
Both men hesitated. Then Northwood strode forward until he was within three feet of Adam. They stood thus, eyeing each other, two splendid beings, one blond as a Viking, the other dark and vital.
"Just what is your game?" demanded Northwood.
The icy eyes shot forth a gleam like lightning. "I needn't tell you, of course, but I may as well let you suffer over the knowledge." He curled his lips with superb scorn. "I have one human weakness. I want Athalia." The icy eyes warmed for a fleeting second. "She is anticipating her meeting with you—bah! The taste of these women of the Black Age! I could kill you, of course; but that would only inflame her. And so I take you to her, thrust you down her throat. When she sees, you, she will fly to me." He spread his magnificent chest.
"Adam!" Dr. Mundson's face was dark with anger. "What of Eve?"
"Who are you to question my ac-
