dispatched to Earth to introduce the principles, which would in time bring about the orderly disintegration of the system of the Machine, to be followed by the establishment of an Earth government with which the Mars Convicts could deal without detriment to themselves. Menesee had listened with a sense of growing angry incredulity. The fellow couldn't be as much of a fool as he seemed! Therefore, he had devised this hoax after he realised he would be captured, to cover up his real purpose which could only be that of a spy. Menesee saw that Administrator Bradshaw was saying something in a low voice to the spokesman, his face stony. Dorn glanced over at him, then looked back at the prisoner and said impassively, "So the goal of your missionary work here is the disintegration of the Machine?"

But not while Earth is ruled by the organization of the Machine." This time, Menesee did not observe the motion of the spokesman's hand. Instead he saw Rainbolt jerk violently to the right. At
