"Don," he said with a laugh in his voice, though it was apparent that he felt slightly guilty about laughing, "got a 'gram from Addison, the project engineer on the solar beam from Terran Electric. Says: 'Finally got through Channing Layer. Power by the megawatt-hour in great shape. But the atmosphere from the Channing Layer right down to the snout of the tube is a dull red scintillation. Something like the driver-tube trail—but it ionizes the atmosphere into ozone. Power by the megawatt, and ozone by the megaton."
"Ozone, hey? Lots of it?"
"Plenty, according to the rest of this. It looks to me like a sort of 'denatured' power system. There it is, all nice and potent, cheap, and unlicensed.

This phase of his plan was working to perfection. Gradually, he was burning share after share out of uninterested hands, by his depredations. Soon he would have enough stock in Interplanetary to stage a grand show, and then he could swing the thing his way.
His worry was not with this affair.
He gloated over that. His belief that he could beat the Venus Equilateral crowd if he fought them on his ground with his weapon was being corroborated. That, plus the fact that he was using some of Venus Equilateral's own thunder to do the job, was giving him to think that it was but a matter of time.
And, he laughed, the poor fools were not aware of their peril. Oh, some bird was trying to buck him, but he was not prepared as Kingman was, nor had he the source of information that Kingman had.
No, the thing that worried him was—
