Space was suddenly colored, for thousands of miles, as the beam struck Craven's ship and seemed to explode in a blast of dazzling indigo light. The ship reeled under the impact of the blow, reeled and weaved in space as the beam struck it and delivered to it the mighty power of the screaming engines back in the engine room.

"What happened?" Greg screamed above the roar.

Russ shrugged his shoulders. "You jarred him a little. Pushed him through space for several hundred miles. Made him know something had hit him, but it didn't seem to do any damage."

"That was pure cosmic I gave him! Five billion horsepower—and it just staggered him!"

"He's got a space lens that absorbs the energy," said Russ. "The lens concentrates it and pours it into a receiving chamber, probably a huge photo-cell. Nobody yet has burned out one of those things on a closed circuit."

Greg wrinkled his brow, perplexed. "What he must have is a special field of some sort that lowers the wave-length and the intensity. He's getting natural cosmics all the time and taking care of them."

"That wouldn't be much of a trick," Russ pointed out. "But when he takes care of cosmics backed by five billion horsepower ... that's something else!"

Greg grinned wickedly. "I'm going to hand him a long heat radiation. If his field shortens that any, he'll have radio beam and that will blow photo-cells all to hell."

He stabbed viciously at the keys on the board and once again the shrill howl of the engines came from the rear of the ship. A lance of red splashed out across space and touched the other ship. Again space was lit, this time with a crimson glow.
