The Prince had, after our first interview, observed with regard to every point of my story on which I had been carefully silent a delicacy of reserve very unusual among Martialists, and quite unintelligible to his Court and officers. To-day the conversation in public turned again upon my voyage. Endo and another studiously directed it to the method of steering, and the intentional diminution of speed in my descent, corresponding to its gradual increase at the commencement of the journey—points at which they hoped to find some opening to the mystery of the motive force. The Prince relieved me from some embarrassment by requesting me as usual to attend him to his private cabinet.

He said:—"I have not, as you must be aware, pressed you to disclose a secret which, for some reason or other, you are evidently anxious to preserve. Of course the exclusive possession of a motive power so marvellous as that employed in your voyage is of almost incalculable pecuniary value, and it is perfectly right that you should use your own discretion with regard to the time and the terms of its communication."

"Pardon me," I interposed, "if I interrupt you, Prince, to prevent any misconception. It is not with a view to profit that I have carefully avoided giving any clue whatever to my secret. Tour munificence would render it most ungrateful and unjust in me to haggle over the price of any service I could render you; and I should be greedy indeed if I desired greater wealth than you have bestowed. If I may say so without offending, I earnestly wish that you would permit me, by resigning your gifts, to retain in my own eyes the right to keep my secret without seeming undutiful or unthankful."

"I have said," he replied, "that on that point you misconceive our respective positions. No one supposes that you are indebted to us for anything more than it was the duty of the Sovereign to give, as a mark of the universal admiration and respect, to our guest from another world; still less could any imagine that on such a trifle could be founded any claim to a secret so invaluable. You will offend me much and only if you ever again speak of yourself as bound by personal obligation to me or mine. But as we are wishful to buy, so I cannot understand any reluctance on your part to sell your secret on your own terms."

"I think, Prince," I replied, "that I have already asked you what you would think of a subject of your own, who should put such a power into the hands of enemies as formidable to you as you would be to the races of the Earth."

"And I think," he rejoined with a smile, "that I reminded you how little my judgment would matter to one possessed of such a power. I have gathered from your conversation how easily we might conquer a world as far behind us in destructive powers as in general civilisation. But why should you object? You can make your own terms both for yourself and for any of your race for whom you feel an especial interest."

"A traitor is none the less a despicable and loathsome wretch because his Prince cannot punish him. I am bound by no direct tie of loyalty to any Terrestrial sovereign. I was born the subject of one of the greatest monarchs of the Earth; I left his country at an early age, and my youth was passed in the service of less powerful rulers, to one at least of whom I long owed the same military allegiance that binds your guards and officers to yourself. But that obligation also is at an end. Nevertheless, I cannot but recognise that I owe a certain fealty to the race to which I belong, a duty to right and justice. Even if I thought, which I do not think, that the Earth would be better governed and its inhabitants happier under your rule, I should have no right to give them up to a conquest I know they would fiercely and righteously resist. If—pardon me for saying it—you, Prince, would commit no common crime in assailing and slaughtering those who neither have wronged nor can wrong you, one of themselves would be tenfold more guilty in sharing your enterprise."

"You shall ensure," he replied, "the good government of your own world as you will. You shall rule it with all the authority possessed by the Regents under me, and by the laws which you think best suited to races very different from our own. You shall be there as great and absolute as I am here, paying only an obedience to me and my successors which, at so immense a distance, can be little more than formal."

"Is it to acquire a merely formal power that a Prince like yourself would risk the lives of your own people, and sacrifice those of millions of another race?"

"To tell you the truth," he replied, "I count on commanding the expedition myself; and perhaps I care more for the adventure than for its fruits. You will not expect me to be more chary of the lives of others than of my own?"
