This mine was, among others, Menjo Bleeko's personal property. Since overproduction would glut the market, it was being worked by only one shift of men—the day shift. It was now black night; the usual guards were the only men upon the premises. The big black ship hung there and waited.

"But suppose they don't, Kim?" Watson asked.

"Then we'll wait here every night until they do," Kinnison replied, grimly. "But they'll do it tonight, for all the tea in China. They'll have to, to save Bleeko's face."

And they did. In a couple of hours the observer at a high-powered plate reported that Cartiff's salon had just been blown to bits. Then the Patrolmen went into action.

Bleeko's mobsmen hadn't killed anybody at Cartiff's, therefore the Tellurians wouldn't kill anyone here. Hence, while ten immense beam-dirigible torpedoes were being piloted carefully down shafts and along tunnels into the deepest bowels of the workings, the guards were given warning that, if they got into their fliers fast enough, they could be fifty miles away and probably safe by zero time. They hurried.

At zero time the torpedoes let go as one. The entire planet quivered under the trip-hammer shock of detonating duodec. For those frightful, those appalling charges had been placed, by computations checked and rechecked, precisely where they would wreak the most havoc, the utmost possible measure of sheer destruction. Much of the rock, however hard, around each one of those incredible centers of demolition was simply blasted out of existence. That is the way duodec, in massive charges, works. Matter simply cannot get out of its way in the first instants of its detonation; matter's own inherent inertia forbids.

Most of the rock between the bombs was pulverized the merest fraction of a second later. Then, the distortedly spherical explosion fronts merging, the total incomprehensible pressure was exerted as almost pure lift. The field above the mine works lifted, then; practically as a mass at first. But it could not remain as such. It could not move fast enough as a whole; nor did it possess even a minute fraction of the tensile strength necessary to withstand the stresses being applied. Those stresses, the forces of the explosions, were to all intents and purposes irresistible. The crust disintegrated violently and almost instantaneously. Rock crushed grindingly against rock, practically the whole mass reducing in the twinkling of an eye to an impalpable powder.

Upward and outward, then, the ragingly compressed gases of detonation drove, hurling everything before them. Chunks blew out sidewise, flying for miles; the mind-staggeringly enormous volume of dust was hurled upward clear into the stratosphere.

Finally that awful dust cloud was wafted aside, revealing through its thinning haze a strangely and hideously altered terrain. No sign remained of the buildings or the mechanisms of Bleeko's richest mine. No vestige was left to show that anything built by or pertaining to man had ever existed there. Where those works had been, there now yawned an absolutely featureless crater; a crater whose sheer geometrical perfection of figure revealed with shocking clarity the magnitude of the cataclysmic forces which had wrought there.

Kinnison, looking blackly down at that crater, did not feel the glow of satisfaction which comes of a good deed well done. He detested it—it made him sick at the stomach. But, since he had had it to do, he had done it. Why in all the nine hells of Valeria did he have to be a Lensman, anyway?
