"Yes. How'd you like to learn to talk English like Crane there does--without taking lessons?" Shiro smiled doubtfully, unable to take such a thought seriously. "Yes, it can be done," Crane assured him. "Doctor Seaton can build a machine which will teach you all at once, if you like." "I like, sir, enormously, yes, sir. I years study and pore, but honorable English extraordinary difference from Nipponese--no can do. Dictionary useful but ..." he flipped pages dexterously, "extremely cumbrous. If honorable Seaton can do, shall be extreme ... gratification." He bowed again, smiled, and went out. "I'll do just that little thing. So long, folks, I'm going up to the shop." * * * * * Day after day the _Skylark_ plunged through the vast emptiness of the interstellar reaches. At the end of each second she was traveling exactly twenty-six feet per second faster than she had been at its beginning; and as day after day passed, her velocity mounted into figures which became meaningless, even when expressed in thousands of miles per second. Still she seemed stationary to her occupants, and only different from a vessel motionless upon the surface of the Earth in that objects within her hull had lost three-sixteenths of their normal weight. Acceleration, too, had its effect. Only the rapidity with which the closer suns and their planets were passed gave any indication of the frightful speed at which they were being hurtled along by the inconceivable power of that disintegrating copper bar. When the vessel was nearly half-way to "X," the bar was reversed in order to change the sign of their acceleration, and the hollow sphere spun through an angle of one hundred and eighty degrees around the motionless cage which housed the enormous gyroscopes. Still apparently motionless and exactly as she had been before, the _Skylark_ was now actually traveling in a direction which seemed "down" and with a velocity which was being constantly decreased by the amount of their negative acceleration. A few days after the bar had been reversed Seaton announced that the mechanical educator was complete, and brought it into the control room. In appearance it was not unlike a large radio set, but it was infinitely more complex. It possessed numerous tubes, kino-lamps, and photo-electric cells, as well as many coils of peculiar design--there were dozens of dials and knobs, and a multiple set of head-harnesses. "How can a thing like that possibly work as it does?" asked Crane. "I know that it does work, but I could scarcely believe it, even after it had educated me." "That is nothing like the one Dunark used, Dick," objected Dorothy. "How come?"
