"Saturn, as we grew, had been seemingly smaller and coming visually nearer to us. Yet our velocity away from it was--in our original size--seven and one-half million miles an hour. Can I make you realize that the effect of _both_ motions was apparent? It was as though we were moving forward to lengthen a dwindling distance, with Saturn following after us simultaneously to shorten it. "It was at the thousand unit point--ourselves then ten miles of earthly height--that I shut off the size-switch. Of visual diameter, Saturn had really not altered materially." Brett stopped as though carefully to choose his words. "I'm striving to give you a clear picture. A distant object of great size may appear of the same diameter as something smaller and closer. But you can generally tell which is which. There is a difference of aspect--impossible to describe, but readily seen. Saturn was like that--the change in the planet was like a progressive change from the one condition to the other. It had appeared large and distant; it changed, to be smaller and closer. Just before I shut off the size-switch, when our rate of growth had become comparatively rapid, Saturn took on other motions--I'll tell you about them in a moment. "Do I make myself clear? I want to. . . . With our growth checked, there was at once a striking, visual result. We seemed receding from Saturn so fast that its apparent diameter dwindled very rapidly--a normal dwindling of rapidly added distance. Presently it was a mere star--then a pin-point of light. Then it was vanished. Our other planets of the Solar System had preceded Saturn into invisibility. Then our sun itself became so faint a star that I lost it. We were beyond the Solar System--itself wholly lost to the naked eye among the great star-clusters enveloping it." V "Wait," I exclaimed. "There is so much I want to ask you, Brett." Frannie interposed timidly: "Did you say, Brett, that on earth the vehicle then would have been ten miles in height?" "Yes," he agreed. She commented, "Then your relative Time-dials must have been visibly moving----" Dr. Gryce hastily interrupted: "The practical workings of the inherent Time-change I want Brett to explain carefully. You did not move the vehicle in Time, did you, Brett?" "No sir. Not then." I must have looked puzzled, for Dr. Gryce added: "We mean, Frank, that the vehicle could have traveled in Time--in earth-Time, for instance, to go into our past or our future. Brett had not done that. But immediately the vehicle started a size-change, you understand, there automatically began a Time-change inherent to that growth. Normal to it, let me say." "Oh, yes," I nodded. "I remember you explained that. In relation to its size----" "I'll put it this way," Dr. Gryce went on. "That girl out there is moving through Time at a definite rate. Let us say a year of our Time would be measured as a second of hers." "Less than that," Martt interjected.
