"The drums, when loaded with talc, are set to attract the proper planetary force and they go speeding toward Venus at the rate of 426,000 miles an hour. They are prevented from colliding with meteors by an automatic magnetic device. This is controlled by magnetic force alone, and when the targo gets too close to a meteor it changes its course instantly. The pa.s.senger targo we ride in acts similarly. And now may I return to the subject of the vampires of Venus?"
"Pardon my ignorance," said Larner, and for the first time in his life he felt very ignorant indeed.
"I know little more than I have told you," said Nern, rather hopelessly.
"Our knowledge of your world, your people and your language comes from our listening in on you and observing you without being observed or heard. This might seem like taking an advantage of you, were it not for the fact that we respect confidences, and subjugate all else to science.
We have helped you at times, by telepathically suggesting ideas to your thinkers.
"We would have given you all our inventions in this way, gladly, but in many instances we were unable to find minds attuned to accept such advanced ideas. We have had the advantage of you because our planet is so many millions of years older than your own." There was a plaintive note in Nern"s voice as he talked.
"But now we are on our knees to you, so to speak. We do not know everything and, desperately, we need the aid of a man of your caliber.
In behalf of the distraught people of Venus, I am asking you bluntly to make a great sacrifice. Will you face the dangers of a trip to Venus and use your knowledge to aid us in exterminating these creatures of h.e.l.l?"
There was positive pleading in his voice, and in the eyes of his beautiful sister there were tears.
"But what would my superiors in the Government Bureau think?" feebly protested Larner, "I could not explain...."
"You have no superiors in your line. Our Government needs you at this time more than any earthly government. Your place here is a fixture. You can always return to it, should you live. We are asking you to face a horrible death with us. You can name your own compensation, but I know you are not interested so much in reward.
"Now, honestly, my good professor, there is no advantage to be gained by explanation. Just disappear. In the name of G.o.d and in the interests of science and the salvation of a people who are at your mercy, just drop out of sight. Drop out of life on this planet. Come with us. The cause is worthy of the man I believe you to be."
"I will go," said Larner, and his hosts waited for no more. An instant later the targo shot out into interstellar s.p.a.ce.
"How do you know what course to follow?" asked Larner after a reasonable time, when he had recovered from his surprise at the sudden take-off.
"We do not need to know. Our machine is tuned to be attracted by the planetary force of Venus alone. We could not go elsewhere. A repulsion ray finds us as we near Venus and protects us against too violent a landing. We will land on Venus like a feather about three months from to-night."
The time of the journey through outer s.p.a.ce was of little moment save for one incident. Larner and the other travelers were suddenly and rather rudely jostled about the rapidly flying craft.
Larner lost his breath but not his speech. "What happened?" he inquired.
"We just automatically dodged a meteor," explained Nern.
Most of the time of the trip was spent by Larner in listening to explanations of customs and traditions of the people of the brightest planet in the universe.
There was a question Larner had desired to ask Nern Bela, yet he hesitated to do so. Finally one evening during the journey to Venus, when the travelers had been occupying themselves in a scientific discussion of comparative evolution on the two planets, Larner saw his opportunity.
"Why," he asked rather hesitatingly, "did the people of Venus always remain so small? Why did you not strive more for height? The j.a.panese, who are the shortest in stature of earth people, always wanted to be tall."
"Without meaning any offense," replied Nern, "I must say that it is characteristic of earth dwellers to want something without knowing any good reason why they want it. It is perfectly all right for you people to be tall, but for us it is not so fitting. You see, Venus is smaller than the earth. Size is comparative. You think we are not tall because you are used to taller people. Comparatively we are tall enough. In proportion to the size of our planet we are exactly the right size. We keep our population at 900,000,000, and that is the perfectly exact number of people who can live comfortably on our planet."
Arriving on Venus, Larner was a.s.signed a laboratory and office in one of the Government buildings. It was a world seemingly made of gla.s.s.
Quartz, of rose, white and crystal coloring, Larner found, was the commonest country rock of the planet. In many cases it was shot full of splinters of gold which the natives had not taken the trouble to recover. This quartz was of a terrific hardness and was used in building, paving, and public works generally. The effect was bewildering. It was a world of shimmering crystal.
The atmosphere of Venus had long puzzled Larner. While not an astronomer in the largest sense of the word, yet he had a keen interest in the heavens as a giant puzzle picture, and he had given some spare time to the study.
He knew that from all indications Venus had a most unusual atmosphere.
He had read that the atmosphere was considerably denser than that of the earth, and that its presence made observation difficult. The actual surface of the planet he knew could hardly be seen due, either to this atmosphere, or seemingly perpetual cloud banks.
He had read that the presence of atmosphere surrounding Venus is indicated to earthly astronomers, during the planet"s transit, by rings of light due to the reflection and scattering of collected sunlight by its atmosphere.
Astronomers on earth, he knew, had long been satisfied of the presence of great cloud banks, as rocks and soils could not have such high reflecting power. He knew that like the moon, Venus, when viewed from the earth, presents different phases from the crescent to the full or total stage.
Looking up at the sky from the quartz streets of Venus, Larner beheld, in sweeping grandeur, ma.s.sed cloud banks, many of them apparently rain clouds.
Nern noted his skyward gaze, and said:
"We have accomplished meteorological control. Those clouds were brought under control when we conquered interplanetary force, and what you call gravity. We form them and move them at will. They are our rain factory.
We make rain when and where we will. This insures our crops and makes for health and contentment.
"The air, you will note, is about the same or a little more moist than the earth air at sea level. This is due to the planet"s position nearer the sun.
"We have been striving for centuries to make the air a little drier and more rare, but we have not succeeded yet. The heavy content of disintegrated quartz in our soil makes moisture very necessary for our crops, so our moist atmosphere is evidently a provision of providence.
We are used to breathing this moist air, and when I first visited the earth I was made uncomfortable by your rarified atmosphere. Now I can adjust myself to breathing the air of either planet. However, I find myself drinking a great deal more water on earth than on Venus."
In this fairyland which had enjoyed centuries of peace, health and accord, stark terror now reigned. In some instances the finely-bred, marvellously intelligent people were in a mental condition bordering on madness.
This was especially true in the farming districts, where whole herds of lats had been wiped out. Lats, Larner gleaned, were a common farm animal similar to the bovine species on earth, only more wooly. On these creatures the Venus dwellers depended for their milk and dairy supplies, and for their warmer clothing, which was made from the skin. The hair was used for brushes, in the building trades, and a thousand ways in manufacturing.
Besides the domestic animals hundreds of people continued to meet death, and only a few of the flying vampires had been hunted down. The giant insects were believed to breed slowly as compared to earth insects, their females producing not more than ten eggs, by estimate, after which death overtook the adult. In spite of this they were reported to be increasing.
In the Government building Larner was placed in touch with all the Government scientists of Venus. His nearest collaborator was one Zorn Zada, most profound scientist of the planet. The two men, with a score of a.s.sistants, worked elbow to elbow on the most gigantic scientific mystery in the history of two planets.
A specimen of the dread invader was mounted and studied by the scientists, who were so engrossed in their work that they hardly took time to eat. As for sleep, there was little of it. Days were spent in research and nights in hunting the monsters. This hunting was done by newly recruited soldiers and scientists. The weapons used were a short ray-gun of high destructive power which disintegrated the bodies of the enemies by atomic energy blasts. The quarry was wary, however, and struck at isolated individuals rather than ma.s.sed fighting lines.
Seated at his work-bench Larner asked Zorn Zada what had become of Nern Bela. In his heart he had a horrible lurking fear that the beautiful Tula Bela might fall before a swarm of the strange vampires, but he did not voice this anxiety.
"Nern and his sister are explorers and navigators," was the reply. "They have been a.s.signed to carry you anywhere on this or any other planet where your work may engage you. They await your orders. They are too valuable as s.p.a.ce-navigators to be placed in harm"s way."
Breathing a sigh of relief, Larner bent to his labors.
"What other wild animals or harmful insects have you on this planet?" he asked Zorn.
"I get your thought," replied the first scientist of Venus. "You are seeking a natural enemy to this deadly flying menace, are you not?"
"Yes," admitted Larner.
"All insects left on Venus with this one exception are beneficial," said Zorn. "There are no wild animals, and no harmful insects. All animals, insects and birds have been domesticated and are fed by their keepers.
We get fabrics from forms of what you call spiders and other web-builders and coc.o.o.n spinners. All forms of birds, beasts and crawling and flying things have been brought under the dominion of man.
We will have to seek another way out than by finding an enemy parasite."
