His host heard him through without a word, but towards the end of his story his face betrayed an interest, or rather an expectant anxiety, to hear what was coming next that no mere friendly concern of the moment for one less fortunate than himself could adequately account for. At length, when Arnold had completed his story with a brief but graphic description of the last successful trial of his model, he leant forward in his chair, and, fixing his dark, steady eyes on his guest's face, said in a voice from which every trace of his former good-humoured levity had vanished-- "A strange story, and truer, I think, than the one I told you. Now tell me on your honour as a gentleman: Were you really in earnest when I heard you say on the embankment that you would rather smash up your model and take the secret with you into the next world, than sell your discovery to the Tsar for the million that he has offered for such an air-ship as yours?" "Absolutely in earnest," was the reply. "I have seen enough of the seamy side of this much-boasted civilisation of ours to know that it is the most awful mockery that man ever insulted his Maker with. It is based on fraud, and sustained by force--force that ruthlessly crushes all who do not bow the knee to Mammon. I am the enemy of a society that does not permit a man to be honest and live, unless he has money and can defy it. I have just two shillings in the world, and I would rather throw them into the Thames and myself after them than take that million from the Tsar in exchange for an engine of destruction that would make him master of the world." "Those are brave words," said Colston, with a smile. "Forgive me for saying so, but I wonder whether you would repeat them if I told you that I am a servant of his Majesty the Tsar, and that you shall have that million for your model and your secret the moment that you convince me that what you have told me is true." Before he had finished speaking Arnold had risen to his feet. He heard him out, and then he said, slowly and steadily-- "I should not take the trouble to repeat them; I should only tell you that I am sorry that I have eaten salt with a man who could take advantage of my poverty to insult me. Good night." He was moving towards the door when Colston jumped up from his chair, strode round the table, and got in front of him. Then he put his two hands on his shoulders, and, looking straight into his eyes, said in a tone that vibrated with emotion-- "Thank God, I have found an honest man at last! Go and sit down again, my friend, my comrade, as I hope you soon will be. Forgive me for the foolishness that I spoke! I am no servant of the Tsar. He and all like him have no more devoted enemy on earth than I am. Look! I will soon prove it to you."
