He slipped back the speed lever, notch by notch. The hand of the dial began receding, but it still marked one hundred and twenty miles a second.
Suddenly, above the roar and hum of the motor, there sounded the voice of Andy.
"Professor!" he shouted. "We"re heading right toward a big, black stone! Is that the moon?"
"The moon? No, we are not half way there," said Mr. Henderson. "Are you sure, Andy?"
"Sure? Yes! I saw it from the window in the pilot-house. We are shooting right toward it."
"Look to the motor, and I"ll see what it is," directed Mr. Henderson to his friend. Followed by the boys, he hurried to the steering tower. His worst fears were confirmed.
Speeding along with a swiftness unrivalled even by some stars, the projectile was lurching toward a great, black heavenly body. "It"s a meteor! An immense meteor!" cried Professor Henderson, "and it"s coming right toward us."
"Will it hit us?" gasped Mark and Jack together.
"I don"t know. We must try to avoid it. Boys, notify Professor Roumann at once. We are in grave danger!"
CHAPTER XVII
TURNING TURTLE
Together Mark and Jack leaped for the engine room. Their faces showed the fear they felt. Even before they reached it, they realized that, at the awful speed at which they were travelling, and the fearful velocity of the meteor, there might be a crash in mid-air which would destroy the projectile and end their lives.
"I wonder if we can steer clear of it?" gasped Jack.
"If it"s possible the professor will do it," responded his chum.
The next instant they were in the engine room, where Mr. Roumann was bending over the Cardite motor.
"Shut off the power!" yelled Jack.
"We are going to hit a meteor!" gasped Mark.
The German looked up with a startled glance.
"Slow down?" he repeated. "It is impossible to slow down at once! We are going ninety miles a second!" He pointed to the speed gauge.
"Then there"s going to be a fearful collision!" cried Jack, and he blurted out the fact of the nearness of the heavenly wanderer.
"So!" exclaimed Professor Roumann. "Dot is bat! ferry bat!" and he lapsed into the broken language that seldom marked his almost perfect English. Then, murmuring something in his own tongue, he leaped away from the motor, calling to the boys:
"Slow it down gradually! Keep pulling the speed lever toward you! I will set in motion the repelling apparatus and go to help Professor Henderson steer out of the way. It is our only chance!"
Mark and Jack took their places beside the Cardite motor, which was still keeping up a fearful speed, though not so fast as at first. To stop it suddenly would mean that the cessation of strain could not all be diffused at once, and serious damage might result.
The only way was to come gradually down to the former speed, and, while Mark kept his eyes on the indicator, Jack pulled the lever toward him, notch by notch.
"She"s down to seventy-five miles a second," whispered Mark. They were as anxious now to reduce speed as they had been before to increase it.
Meanwhile Professor Roumann had set in motion a curious bit of apparatus, designed to repel stray meteors or detached bits of comets.
As is well known, bodies floating in s.p.a.ce, away from the attraction of gravitation, attract or repel each other as does a magnet or an electrically charged object.
Acting on this law of nature, Professor Roumann had, with the aid of Mr. Henderson, constructed a machine which, when a negative current of electricity was sent into it, would force away any object that was approaching the _Annihilator_. In a few moments the boys at the Cardite motor heard the hum, the throb and crackling that told them that the repelling apparatus was at work.
But would it act in time? Or would the meteor prove too powerful for it? And, if it did, would the two scientists be able to steer the swiftly moving projectile out of the way of the big, black stone, as the old hunter called it?
These were questions that showed on the faces of the two lads as they bent over the motor.
"We"re only going fifty miles a second now," whispered Jack.
Mark nodded his head. "Can"t you pull the lever over faster?" he asked.
"I don"t dare," replied his chum. There was nothing to do but to wait and gradually slow up the projectile as much as possible. The boys could hear the professors in the pilothouse shifting gears, valves and levers to change the course of the projectile. Andy Sudds and Washington White, with fear on their faces, looked into the engine room, waiting anxiously for the outcome.
"Hab--hab we hit it yet?" asked Washington, moving his hands nervously.
"I reckon not, or we"d know it," said the hunter.
"No, not yet," answered Jack, in a low voice. "How much are we making now, Mark?"
"Only thirty a second."
"Good! She"s coming down."
Hardly had he spoken than there sounded a noise like thunder, or the rushing of some mighty wind. The projectile, which was trembling throughout her length from the force of the motor, shivered as though she had plunged into the unknown depths of some mighty sea. The roaring increased. Mark and Jack looked at each other. Washington White fell upon his knees and began praying in a loud voice. Old Andy grasped his gun, as though to say that, even though on the brink of eternity, he was ready.
Then, with a scream as of some gigantic sh.e.l.l from a thousand-inch rifle, something pa.s.sed over the _Annihilator_; something that shook the great projectile like a leaf in the wind. And then the scream died away, and there was silence. For a moment no one spoke, and then Jack whispered hoa.r.s.ely:
"We"ve pa.s.sed it."
"Yes," added Mark, "we"re safe now."
"By golly! I knowed we would!" fairly yelled Washington, leaping to his feet. "I knowed dat no old meteor could kerflumox us! Perfesser Henderson he done jumped our boat ober it laik a hunter jumps his boss ober a fence. Golly! I"se feelin" better now!"
"How did you avoid it?" asked Mark of the professor.
"With the help of the repelling machine and by changing our course. But we did it only just in time. It was an immense meteor, much larger than at first appeared, and it was blazing hot. Had it struck us, there would have been nothing left of us or the projectile either but star dust. But we managed to pa.s.s beneath it, and now we are safe."
They congratulated each other on their lucky escape, and then busied themselves about various duties aboard the air-craft. The rest of the day was spent in making minor adjustments to some of the machines, oiling others, and in planning what they would do when they reached the moon.
In this way three days and nights pa.s.sed, mainly without incident. They slept well on board the _Annihilator_, which was speeding so swiftly through s.p.a.ce--slept as comfortably as they had on earth. Each hour brought them nearer the moon, and they figured on landing on the surface of that wonderful and weird body in about three days more.
It was on the morning of the fourth day when, as Mark and Jack were taking their shift in the engine room, that Jack happened to glance from the side observation window, which was near the Cardite motor.
What he saw caused him to cry out in surprise.
