"Then," pursed the girl deliberately, "the Capellans have divided the world between them, so that the working classes inhabit one-half, and the capitalists the other?" The doctor explained that the dividing was all done by the owners. "Every bit of the land on the residence planet is privately owned, with the exception of certain small amusement tracts. Theoretically, the planet is open to one and all; practically no worker is welcome there for more than a few hours, and then only in one of those parks. There is no hotel." Van Emmon was straining his memory. "Let's see--I heard Powart name the place. He called it--called it--Hafen!" "Yes. And the other--the world which is the home of the working people, but which they do not own; the world whose factories and farms provide a standard living for the workers and lives of luxury for the owners--this world is known as Holl. But if I read young Ernol's mind aright, these words mean nothing more or less than--Heaven and hell!" XII CAUSE AND EFFECT From that time on the four did not hold any more formal discussions of what they learned. This was due to a most extraordinary discovery. They found that they could keep in touch with each other while they were "visiting"! It was a tremendous help; it enabled them to communicate and compare notes as they went along. The doctor declared that the Venusians themselves had not been able to do more. Thus, when Powart called on Mona a few days after she had declined his ring, Billie was able to tell the other three all that took place, as fast as it happened. As usual, Powart's stay was a brief one. "I hope you have recovered your former self-confidence," said he, consciously repressing the masterful note in his voice. "Not that I am unwilling to wait, Mona." "You are very patient," she assured him. "I am glad to say that I am no longer troubled with any doubts of myself. Something else worries me now." He frowned at the implication. "What is it?" coldly. "Frankly, it is your record." She knew she was jarring him terribly, but she went on with evident relish, "You are the most important man in the world. Odd, isn't it, that I should find fault with that? But it is a serious objection. You are still a very young man; you have become one of the commission; for a year, you are its head. The point is, what's before you?" She paused to let this take effect. "You've already accomplished all that any man can possible accomplish in the political field. You haven't any future!" Powart grasped the thought with his usual instant decision. "I understand. You are right, too. I had not thought of it before." A slight pause. "You fear that you may come to tire of me; is that it?" She nodded emphatically. "If you had asked me a few years ago, before you had reached the top--it would have been different." He remained standing, frowning hard. Presently he glanced at his watch, and said he would have to be going.
