Another blast from the rockets, this one of interminable length, and I must have lost consciousness. For when I next took note of things I found that we had been out for nearly two hours and that the tremendous pressure of acceleration was relieved. I moved my head, experimentally and found that my senses were normal, though there was a strange and alarming sensation of being wrong side up. Then I remembered that I had experienced the same thing when we first searched the upper levels of the atmosphere for the origin of the destructive rays of the enemy.
But this was different! I gazed through a nearby port and saw that the sky was entirely black, the stars shining magnificently brilliant against their velvet background. Streamers of brilliant sunlight from the floor ports struck across the cabin and patterned the ceiling. Looking between my feet I saw the sun as a flaming orb with streamers of incandescence that spread in every direction with such blinding luminosity that I could not bear the sight for more than a few seconds. Off to what I was pleased to think of as our left side, there was a huge globe that I quickly made out as our own earth. Eerily green it shone, and, though a considerable portion of the surface was obscured by patches of white that I recognized as clouds, I could clearly make out the continents of the eastern hemisphere. It was a marvelous sight and I lost several minutes in awed contemplation of the wonder. Then I heard Hart laugh.
"Just coming out of it, Jack?" he asked.
I stared at him foolishly. It had seemed to me that I was alone in this vast universe, and the sound of his voice startled me. "Guess I'm not fully out of it yet," I said. "Where are we?"
"Oh, about sixty thousand miles out," he replied carelessly; "and we are traveling at our maximum speed—that is, the maximum we need for this little voyage."
"Little voyage!" I gasped. And then I looked at George and the professor and saw that they, too, were grinning at my discomfiture. I laughed crazily, I suppose, for they all sobered at once.
Traveling through space at more than forty thousand miles an hour, it seemed that we were stationary. Movement was now easy—too easy, in fact, for we were practically weightless. The professor was having a time of it manipulating a pencil and a pad of paper on which he had a mass of small figures that were absolutely meaningless to me. He was calculating and plotting our course and, without him, we should never have reached the object we sought.
Time passed rapidly, for the wonders of the naked universe were a never-ending source of fascination. Occasionally a series of rocket charges was fired to keep our direction and velocity, but these were light, and the acceleration so insignificant that we were put to no discomfort whatever. But it was necessary that we keep our straps buckled, for, in the weightless condition, even the slightest increase or decrease in speed or change in direction was sufficient to throw us the length of the cabin, from which painful bruises might be received.
