"War in space,” said Russ, musingly. “That's what it will be."

"Chambers and his gang won't fight according to any rules. There'll be no holds barred, no more feeble attempts like the one they tried tonight. From now on we need a base that simply can't be located."

"The ship,” said Russ.

CHAPTER FOURTEEN

The Invincible hung in space, an empty, airless hull, the largest thing afloat.

Chartered freighters, leaving their ports from distant parts of the Earth, had converged upon her hours before, had unloaded crated apparatus, storing it in the yawning hull. Then they had departed.

Now the sturdy little space-yacht, Comet, was towing the great ship out into space, 500,000 miles beyond the orbit of the Moon. Slowly the hull was being taken farther and farther away from possible discovery.

Work on the installation of the apparatus had started almost as soon as the Comet had first tugged at the ponderous mass. Leaving only a skeleton crew in charge of the Comet, the rest of the selected crew had begun the assembly of the mighty machines which would transform the Invincible into a thing of unimaginable power and speed.

The doors were closed and sealed and the air, already stored in the ship's tanks, was released. The slight acceleration of the Comet's towing served to create artificial weight for easier work, but not enough to handicap the shifting of the heavier pieces of apparatus. An electric cable was run back from the little yacht and the Invincible took her first breath of life.

The work advanced rapidly, for every man was more than a mere engineer or spacebuster. They were a selected crew, the men who had helped to make the name of Gregory Manning famous throughout the Solar System.
