Brett said, "I was careful to obey you, Father. We were safely beyond Saturn--and Uranus and Neptune were on the other side of the sun--before I even touched the size-switch. From the orbit of Mars to that of Jupiter there are some 334 million miles between the points we crossed. We were about 112 hours making the voyage. I kept us well away--some ten million miles. But the planet was a beautiful sight, assuming every phase from full to crescent as we passed. You have never been so close, Father? Nor you, Frank?" "Nor I," spoke up Frannie. She said it in a whimsical fashion of pathos, as though to make us all realize that she had been neglected. Brett laughed affectionately. "No, nor you, little sister. Well, it's a beautiful sight. You can see it similarly in the telescope, but somehow, at the same visual distance the naked eye shows it indefinably different. A beautiful silver disk with the broad dark bands upon it and the red spot glowing like a lantern in its lower hemisphere. "Our velocity was slackened for a time as we passed Jupiter, since I had to lose its great attractive force and turn a neutral side to it. But once by it, with it blazing as a gigantic thin crescent above us, I used a full power of its repulsion. We gained velocity rapidly. With the region of minor planets passed I had no fear of using all the velocity we could obtain. I think Nogar was unskilful in the handling of his vehicle; at all events, before we reached the neighborhood of Saturn, we had attained a velocity of seven and a half million miles an hour. It was the greatest velocity we reached." "But," I exclaimed, "but Brett, at seven and one-half million miles an hour, in your whole life-time--whether you changed your Time-rate or not, you would have to live those hours--in a whole life-time at that velocity you wouldn't get one-quarter of the distance even to the nearest star!" "No," he agreed. "But I began using the size-change after we passed Saturn----" I interrupted again. "I've been wondering about that--I don't quite see----" "I'll make it clear to you, Frank, in a moment," Dr. Gryce put in. "Go on, Brett." "We were well past Saturn before I changed our size at all. Our average velocity along there was six million miles an hour--it was a run of about seventy-five hours. We would have been--even at our maximum of seven and one-half million miles an hour--more than another 240 hours getting past Neptune's orbit. It was too tedious. We determined, since Uranus and Neptune were in other parts of their orbits--far on the other side of our sun--I decided that once we were well beyond Saturn, I would start our increase of size. We were seventy million miles beyond Saturn, with nothing of importance ahead of us but the distant stars, when I determined to start the change. The space there was comparatively deserted--a few asteroids--sometimes we could go nearly an hour without even sighting one.
