a bit, landed again, and immediately there came out of it one of the torpedo-ship machines! None of these had gone in, it had been made by those slim, quick worker machines! And now there lumbered out a second machine--one of the strange hull maker machines--then two of the worker machines came out, where only one had gone in. The ship was complete, even to its strange crew! And now that strange crew was already at work, making others! With the coming of dawn the televisors were rayed out of existence. But that evening more were installed, and every night during all that invasion there floated above them those noiseless televisors. They destroyed many, but many remained. That night showed us a fleet of nearly a half million of the tiny torpedo-ships, and a rapidly growing cargo ship camp. There were more than a hundred now, for as each was completed, the machines made could aid in the more rapid construction of the next. And that night they began their work of leveling Mars. That great fleet spread itself out over all the surface of Mars, and with flaming heat rays and the terrible Dis rays they cut down every remnant of the Martian hills. Twenty-four hours later the entire planet was one vast featureless plain. And on that plain there had been established eight camps. During this time the cargo ships had been moving, and during that twenty-four hours they did nothing. But Man was prepared. The radio-controlled fleet was ready to be given its first try. The entire fleet was assembled above the surface of Mars, above that original camp, where still rested the one sphere. Then from far out in space the great control ships directed the dive of the radio-control-ships, making the distance one-twentieth part of a light second. The men directing the ships were no faster than that, could not respond sooner, and the greater distance gave them greater safety.
