warning of the meteorometers, the pilot glanced quickly at
their direction-dials and then touched the rocket-throttles to change
course slightly. The cruiser was threading a way through unseen but
highly perilous swarms of rushing meteors and scores of thundering
asteroids.

Vesta was now a bright, pale-green disk like a little moon. It was not
directly ahead, but lay well to the left. The cruiser was following an
indirect course that had been laid to detour it well around one of the
bigger meteor-swarms that was spinning rapidly toward Mars.

"What about it, Mr. Kenniston--is it safe to turn toward Vesta now?"
Captain Walls asked anxiously. "The chart doesn't show any more swarms
that should be in this region now, by my calculations."

Kenniston snorted. "Charts are all made by planet-lubbers. There's a
small swarm that tags after that big No. 480 mess we just detoured
around. Let me have the 'scopes and I'll try to locate it."

Using the meteorscopes whose sensitive electromagnetic beams could
probe far out through space, to be reflected by any matter, Kenniston
searched carefully. He finally straightened from the task.

"It's all right--the tag-swarm is on the far side of No. 480," he
reported. "It should be safe to blast straight toward Vesta now."

The captain's anxiety was only partly assuaged. "But when we reach the
asteroid, what then? How do we get through the satellite-swarm around
it?"

"I can pilot you through that," Kenniston assured him. "There's a
periodic break in that swarm, due to gravitational perturbations of
the spinning meteor-moons. I know how to find it."

"Then I'll wake you up early tomorrow 'morning' before we reach
Vesta," vowed Captain Walls. "I've no hankering to run that swarm
myself."

"We'll be there in the morning?" exclaimed Gloria with eager delight.
"How long then will it take us to find the pirate wreck?"

Kenniston uncomfortably evaded the question. "I don't know--it
shouldn't take long. We can land in the jungle near the wreck."

His feeling of guilt was increased by her enthusiastic excitement. If
she and the others only knew what the morrow was to bring them!

He did not feel like facing the rest of them now, and lingered on the
dark deck when they went back down from the bridge. Gloria remained
beside him instead of going on to the cabin.

She stood, with the starlight from the transparent deck-wall falling
upon her yo
