visible motion across the sky. It was the molten globe
of what had been the _Prometheus_ and its cargo, locked in its
sub-lunar orbit around Titan. But it was calculated to provide
sufficient warmth and light to a small world such as this, for ten
Earth-years, without renewal.

Colonists were clearing away the wreckage of the now useless airdomes,
and putting their cottages in order. But they still looked around in
awe at the miracles that ended their space-nostalgia, making them feel
truly at home here. Down in the valley there was even a great lake of
rainwater from condensed steam--one of the end-products of the process
that had gone on in the rocks of the great crater on the other side of
Titan. That process had died to a sleepy smoking, now; but all over
this moon of Saturn there were many lakes.

Big Lawler chuckled gleefully, the sound rumbling deep in his chest.
"Rejuvenation of burnt-out spheres on a really progressive basis," he
growled. "No obsolete, jury-rigged junk! Expensive? Sure! But we can
pay for it! Out there are Saturn's metal-rich Rings!"

Bert was thinking that the same trick could be used on any world with
enough gravity to hold down a respectable atmosphere. Half-dead Mars.
Jupiter's four biggest moons. Some of the other satellites of Saturn.
Mercury.

"The one thing that burns me is that my brother, Nick, and Doc Kramer,
and those two colonists, had to die!" Bert grated. "Poor Doc. He was
rich from the atomic engines he invented. And I knew long ago that, by
his will, all his stock is to be put in trust for the welfare of
spacemen and colonists. Should we feel glad or humble?"

Lawler's grin had become a snarl. "Damn Trenton Lauren!" he said.

Alice didn't exactly smile. "I should have told you before this," she
offered seriously, "but death always upsets me. By radio report from a
scouting Patrol boat an hour ago, Lauren and his stooges were found,
smashed and burned in the crash of their craft a hundred miles from
camp. Their half-repaired spaceboat killed them."

Bert and Lawler exchanged glances. Their anger faded.

"What's new from the Safe Products Approval Board, Allie?" Lawler
asked at last. "You seem to find things out fast."

"Nothing new," she answered. "The latest messages are much the same as
those from a while ago. Guarded enthusiasm, and the statement that an
okay for the Kramer Methods must be withheld pending complete and
prompt investigation. Can't blame them. Caution
