Ripon's craggy profile with its jutting beard was silhouetted against the moon as he bent over his dials and switches. Twice he checked them, then he lifted one hand.
"Ready—cut rockets!" he snapped. Larry threw over the lever of the engine room indicator, and the roar of the rockets abruptly ceased.
The sudden silence was strangely startling to ears that had become accustomed to that steady pounding astern. Running feet sounded in the passage as Colton came charging into the control room to find what had gone wrong. For a moment Larry had a sensation of falling, and then the Sky Maid danced about like a leaf in a wind. He steadied himself by clinging to a stanchion and anxiously watched Ripon. The gaunt scientist was hunched above his control boards like a gnome, his hands leaping from switch to dial and back again at furious speed.
Then the motion abruptly ceased. The Sky Maid became steady as a rock, with the bright disc of the Moon dead ahead through the forward port. There was a faint singing sound from one of the control boxes, but otherwise everything was so quiet and still that it seemed as though the ship lay motionless in space. Then Larry looked at the speed indicator, and saw the needle moving steadily upward. The Sky Maid was shooting through the heavens at a speed faster than she had ever traveled when she was new and in good condition!
"Gentlemen," said Ripon, solemnly shaking hands with both Larry and Colton, "this is an historic moment! This is a prelude to that day when interplanetary travel becomes as commonplace as are rocket ship flights through the strathosphere nowadays! No longer will the name of Crispin Gillingwater Ripon be a thing of scorn and derision. And just wait till I get a chance to spit in the faces of some of those living fossils back at the National University...."
"If the ship holds together!" Larry said. Ripon sighed.
"You would bring that up, young feller. But maybe our luck will hold good. At least this method of travel is less hard on an old craft than the steady strain of a rocket blast. If the ship holds together, we'll be on the Moon in forty-eight hours!"
Colton was grinning broadly as Ripon left the control room a minute later. The second officer gave the points of his mustache an added twist, and then rubbed his hands together.
"Looks like the old goat really came through with something after all," he said. Larry looked at him grimly. For all Ripon's eccentricities, he was an able man in a great many things. It annoyed Larry to hear somebody like Colton, a confessed thief and an indifferent officer, speak of him in quite that tone of disrespect.
