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.

The material seemed to be fine blue ashes and on his tongue it had a
soapy savor. He peered at Jaska, whose eyes were glowing with
excitement, whose lips were parted with anticipation, and instantly he
opened a mental conversation with her.

"We must speak with each other telepathically, but do not speak with
me until I have explained to you how to mask your thoughts from all
persons save the one with whom you hold converse! First, I love you!
Second, let us see if, searching the sky, we can find the Earth!"

In a few brief, highly technical words, Sarka told his beloved how to
talk with him in the manner which he had never before explained to
her. They had used telepathy before, countless times, but they had not
cared who heard--while now secrecy in all things was the prime
essential for success, even for life.

When he had told her, and she replied, "I understand perfectly, and it
seems quite easy," they turned and surveyed the heavens, out of which,
by this new miracle of the secret exit dome, they had dropped to the
face of the Moon.

Away across the space between worlds, its transfiguration plainly
visible to the two, they could make out and identify the world from
which they had come. Save that they knew themselves standing on the
Moon, they would have thought as far as appearances went, that the
place where they had come was the Moon, many times enlarged. It seemed
incredible that they had come so far in the twinkling of an eye; but
that they had was proved by the fact of their physical presence.

"Look, Jaska!" said Sarka suddenly. "See how our Earth glows, as
though it were afire inside!"

They stared at the great circular yellowish flame that he pointed out,
and Sarka
