gentle little scientist who had been murdered! And on him, Bert
Kraskow. And where was the rat, Lauren? On his way to the colonized
moons of Jupiter, or even Mars, yelling and accusing by radio all
along the line?

As consciousness faded further, Bert stopped thinking unpleasant
things. His mind drifted into Doc Kramer's dream--of the changes which
would make the near-dead worlds of space really habitable and
homelike, fit for human colonists. It was a beautiful, lost vision.

He was out cold, then, for several Earth-days, and only dimly aware
for many days afterward. He knew that he was in the ship's sick-bay,
and that Lawler and other men were there, too. He heard their voices,
and his own, without remembering what was said. Alice often came to
see him. Often he heard roaring, watery sounds, as of vast rains.

Gradually he came out of the dream-like period, learning of what had
happened. Until the time when he walked from the sick-bay, unsteadily,
but on the mend.

Alice, at his elbow, spoke: "It was like Doc Kramer planned, Bert,
solving the hardest problem."

He knew what this meant. Transmutation, or any atomic process, must
involve the generation of much radioactivity that can destroy life. In
the Big Pill, the problem was to make all the atoms break, and
rearrange their components into new elements as cleanly and sharply as
possible, so that residual atomic instability--radioactivity, that
is--would not linger for years, but would disappear quickly.

"Titan's new atmosphere is clean and breathable, now, Bert," Alice
went on. "And likewise the radioactive poisons that made you and
Lawler and the others very ill disappeared quickly from your bodies.
However, two colonists were beyond saving."

Lawler was with the Kraskows. They went out of the ship without the
cumbersome protection of spacesuits. A Space Patrolman hovered like a
worried hawk, watching Bert, but the latter seemed not to mind.

Far above, replacing the hard stars and blackness of space, common to
the firmaments of all dead and near-dead worlds, were great fleecy
clouds and blue sky. The atmosphere, because of Titan's low gravity,
was highly expanded and hence thin, but rich in oxygen. The breeze
smelled cool and fresh. Overhead was a second sun, seemingly much
larger in diameter than the distant central orb of the solar system.
It crept with
