know.â
âItâs already taken us all day to get this far up.â
âWhat do you mean? Weâve only been flying for about an hour.â
âBut itâs night,â Joe said, pointing to the window.
âOh, no,â Danny said, laughing. âThe air gets thinner and thinner as we go higher, and what we call blue sky is just the effect of the air on light waves. Thatâs why the sky seems to be getting darker now and why we can see the stars. Weâre up where the air is thinned out.â
Danny left his friend sitting on the bunk and went to watch the Professor, who was busily turning on various instruments, reading dials, and making notes.
âYou know,â Danny said, âitâs a strange thing, but I feel very light somehow. Like Iâm walking on air. Is it because weâre up so high?â
âIn a way, you are walking on air,â the Professor replied. âThe anti-gravity paint is shielding us from the earthâs pull. Not altogether, since we havenât got it turned on fullâluckily you didnât move that lever all the way overâbut enough so that, as we go higher, our weight lessens.â
Dr. Grimes came down the ladder. âWhatâs the reading now?â he asked.
âOne hundred and eighty-five miles,â The Professor glanced at a dial. âAt our present speed we have another seven or eight minutes.â
âFantastic!â Dr. Grimes looked at the television screen. âI still canât believe it. And without rocketsâ!â
The Professor grinned. Then he went to a cupboard above the stove and poked around in it for a moment or two. He brought out four bottles of ginger ale.
âGentlemen,â he said, looking around with twinkling eyes, âwe are making history. I think the occasion calls for a little celebration. Let us drink a toast to the exploration of space.â
He handed round the ginger ale and some straws.
âDanny,â he said, âyou have a lively mind. Canât you give us a song, or a poem, that will fit this moment?â
âNot me,â said Danny. âPoetry is Joeâs department. Heâs good at that.â
Joe smiled bashfully; he was beginning to feel much better. He thought for a moment, and then he recited:
I am a boy who has always thought it was quite a trip from home plate to first base,
And now, all of a sudden, I find myself on the way to outer space;
I can imagine myself zipped inside a leather briefcase
Or in some even more unlikely place,
But I find it hard to realize that I am on the way to outer space.
I can picture myself as a contender in a three-legged race,
Or as a movie star with a million-dollar face;
In fact, just about the only way I cannot picture myself
Is on the way to outer space.
He dropped his eyes modestly as the other three applauded.
Professor Bullfinch said, âDo you mind if I set that to music?â
âOh, come on,â Joe mumbled. âQuit kidding.â
âNo, really, Joe, it was very good indeed.â The Professor raised his bottle. âTo our excellent bard. Drink up.â
They drank, and he added, âGrimes, watch the altimeter and speed dials. Iâm about to cut down the current.â
He took hold of the red lever. Grimes bent over the control board.
âOh-ten,â he began counting. âOh-nine, oh-eight, oh-sevenââ
The Professor pushed the handle a little way toward the right.
ââoh-three,â said Grimes, âoh-two, oh-one, zero. Two hundred miles, Bullfinch.â
The Professor slowly drew the red lever farther over.
âThatâs it,â he said decisively. He glanced through the window. âOur trip is over. But it was a magnificent, an unforgettableââ
He broke off.
At the same time Dr. Grimes clutched the edge of the control panel with both hands and shouted, âBullfinch! Thereâs something
