he inner door closed upon Sarka and Jaska, and, hand in hand, side by side, their bodies glowing with knowledge of warm, sympathetic contact, they waited for a miracle which had never before been attempted.

"Are you afraid, beloved?" queried Sarka.

"When I am with you," she said softly, "I have no fear."

"Then face the outer door, and will to go wherever I will to take you!"

Side by side, hand-in-hand still, they faced the outer door, and Sarka willed:

"Let us appear together in a deserted spot, within sight but unseen, of the Moon crater from which those aircars were sent against us!"

A sudden blur, a cessation of all knowledge, and then....

Sarka and Jaska stood side by side in a desolate expanse surrounded by bleak and appalling mountains of grotesque shape, in a light that was weirdly, awesomely blue. Their feet were invisible, deeply rooted in some soft, fine material which looked like snow.

After a swift glance around to see if anything lived or moved in this awful desolation, Sarka stooped and dipped up some of the fine stuff with his fingers, touched it to his lips.
