Half-dragged and half-floating they were led toward an opening in the roof from which a stair led downward. They pa.s.sed down thus into the building"s interior, lit by many windows. Norman glimpsed long halls ending in barred doors, guards here and there. Tube-lines ran along the walls and somewhere machines were throbbing dully. They came at last to a barred door whose guard opened it at the croaking order of the frog-men who held the two, and they were thrust inside, as the door clanged. They turned, and exclaimed in amazement. The room held fully a half-hundred men!
They were men such as the two fliers had never seen before, like humans except that their skins were a light green instead of the normal white and pink. They were dressed in dark short tunics, and kept talking to each other in a tongue quite unintelligible to Norman and Hackett. They came closer, flocking curiously around the two men, with a babel of voices quite meaningless to the two. Then one of the men uttered an exclamation, and all turned.
The barred door had swung open and a half-dozen frog-guards entered, followed by two frog-men carrying a square little mechanism from which tubing led back out through the door.
"Norman--these men--" Hackett was whispering rapidly. "If there are men in this world too, it may be that--"
"Quiet, Hackett--look at what they"re doing."
The two frog-men had set their mechanism in place and then croaked out a brief word or order. Slowly, reluctantly, one of the green men moved toward them. Quickly they removed a metal disk fastened to his arm, exposing a small orifice like an unhealed wound. Onto this they fastened a suckerlike object from which a transparent tube led back through the mechanism. The machine hummed and at once a red stream pulsed through the tube and back through the mechanism. The man to whom it was attached was growing rapidly pale!
Norman, sick with horror, clutched his companion. "Hackett--these frog-men are sucking his blood from him!"
"Good G.o.d! And look--they"re doing it with another!"
"All of these men--kept prisoners to furnish them with blood. It must be the d.a.m.ned creatures" food! And we here with the others--"
A common horror shook the two. It did not seem to affect the green men in the room, though, who advanced to the mechanism one by one with a reluctant air as of cows unwilling to be milked. Each was attached to the mechanism by the sucking disk on his arm, and out of each the blood poured through the tube. The metal disk was replaced on his arm then and he went back to the others. Norman saw that the frog-men took only from each an amount of blood that they could lose and yet live, since, though each came back pale and weak from the mechanism, they were able to walk.
"It must be their food--human blood!" Norman repeated. "They may have thousands on thousands of humans penned up like this, like so many herds of cows, and perhaps they live entirely on the life-blood they milk from them. Human cows--G.o.d!"
"Norman--look--they"re calling to us!"
The two stiffened. All the others in the room had taken their turn at the blood-sucking mechanism and now the frog-men croaked their order to the two fliers. They had forgotten their own predicament in the horror of the scene, but now it became real to them. They backed against the room"s wall, quivering, dangerous.
The frog-guards came forward to drag them to the machine. A webbed paw was outstretched but Hackett with a wild blow drove the frog-man back and downward. The frog-guards leaped, and Norman and Hackett struck them back with all the greater strength the lesser gravitation gave them. The room was in an uproar, the green men shouting hoa.r.s.ely and seeming on the point of rushing to their aid.
But the menacing force-pistols of the other frog-guards held back the shouting men and in moments the two fliers were overpowered by sheer weight of frog-bodies. Norman felt himself dragged to the machine.
Pain needled his upper arm as an incision was made. He felt the sucking-disk attached; then the machine hummed, and a sickening nausea swept him as the blood drained from his body. Held tightly by the guards he went dizzy, weak, but at last felt the sucker removed and a metal disk fastened over the incision. He was jerked aside and Hackett, his face deathly white, was dragged into his place. In a moment some of the latter"s blood had been pumped from him also.
The machine was withdrawn, Norman and Hackett were released, and the frog-men, with their black force-pistols watchfully raised, withdrew, the door clanging. The room settled back to quietness, the green men stretching in la.s.situde on the metal bunks around it. The two fliers crouched down near the door, shuddering nausea and weakness still holding them.
Norman found that Hackett was laughing weakly. "To think that twenty-four hours ago I was in New York," he half-laughed, half-sobbed. "On Earth--Earth--"
The other gripped his arm. "It"s horrible, Hackett, I know. But it isn"t instant death, and we"ve still a chance to escape. h.e.l.l, can d.a.m.n frog-men keep us here? Where"s your nerve, man?"
A voice beside them made them turn in amazement. "You are men from Earth?" it asked, in queerly accented English. "From Earth?"
Astonishment held them as they saw who spoke. It was one of the green men in the room, who had settled down by their side. A tall figure with superb muscles and frank, clean countenance, his dark eyes afire with eagerness.
"English?" Norman exclaimed. "You know English--you understand me?"
The other showed his teeth in a smile. "I know, yes. I"m Sarja, and I learned to speak it from Fallas, in my city, before the Ralas caught me."
"Fallas--" Norman repeated, puzzled; then suddenly he flamed. "By G.o.d, he means Fellows!"
"Fallas, yes," said the other. "From the sky he fell into our city in a strange flying-boat that was smashed. He was hurt but we cared for him, and he taught me his speech, which I heard you talking now."
"Then Fellows is in your city now?" asked Hackett eagerly. "Where is that?"
"Across this sea--back in the hills," the other waved. "It is far from the sea but I was rash one day and came too near the water in my flying-boat. The Ralas were out raiding and they saw me, caught me, and brought me here. No escape now, until I die."
"The Ralas--you mean these frog-men?" Norman asked.
Sarja nodded. "Of course. They are the tyrants and oppressors of this world. Our little world is but a tenth or less the size of your great Earth which it circles, but it has its lands and rivers, and this one great fresh-water sea into which the latter empty. In this sea long ago developed the Ralas, the great frog-men who acquired such intelligence and arts that they became lords of this world.
"Through the centuries, while on the land our races of green men have been struggling upward, the Ralas have oppressed them. Long ago the Ralas left all their other cities to build this one great amphibian city at the sea"s center. Entrance to it is only by the water-tunnel from without, and being frog-people entrance thus is easy for them since they can move for many minutes under water, though they drown like any other breathing animal if kept under too long. Humans dare not try to enter it thus by the water-tunnel, since, before they could find it and make their way up through it, they would have drowned.
"So the Ralas have ruled from this impregnable amphibian city. Its colossal metal dome is invulnerable to ordinary attack, and though solid and without openings it is always as light beneath the dome here as outside, since the Ralas" scientists contrived light-condensers and conductors that catch light outside and bring it in to release inside.
So when it is day outside the sunlight is as bright here, and when night comes the Earth-light shines here the same as without.
"From this city their raiding parties have gone out endlessly to swoop down on the cities of us green men. Since we learned to make flying-boats like theirs, with molecular-motors, and to make the guns like theirs that fire sh.e.l.ls filled with annihilating force, we have resisted them stoutly but their raids have not ceased. And always they have brought their prisoners back in to this, their city.
"Tens of thousands of green men they have prisoned here like us, for the sole purpose of supplying them with blood. For the Ralas live on this blood alone, changing it chemically to fit their own bodies and then taking it into their bodies. It eliminates all necessity for food here for them. Every few days they drain blood from us, and since we are well fed and cared for to keep us good blood-producers, we will be here for a long time before we die."
"But haven"t you made any attempt to get out of here--to escape?"
Norman asked.
Sarja smiled. "Who could escape the city of the Ralas? In all recorded history it has never been done, for even if by some miracle you got a flying-boat, the opening of the water-tunnel that leads outward is guarded always."
"Guards or no guards, we"re going to try it and not sit here to furnish blood for the Ralas," Norman declared. "Are you willing to help, to try to get to Fellows and your city?"
The green man considered. "It is hopeless," he said, "but as well to die beneath the force-sh.e.l.ls of the Ralas as live out a lifetime here.
Yes, I will help, though I cannot see how you expect to escape even from this room."
"I think we can manage that," Norman told him. "But first--not a word to these others. We can"t hope to escape with them all, and there is no knowing what one might not betray us to the frog-men."
He went on then to outline to the other two the idea that had come to him. Both exclaimed at the simpleness of the idea, though Sarja remained somewhat doubtful. While Hackett slept, weak still from his loss of blood, Norman had the green man scratch on the metal floor as well as possible a crude map of the satellite"s surface, and found that the city, where Fellows was, seemed some hundreds of miles back from the sea.
While they talked, the sunlight, apparently sourceless, that came through the heavily barred windows of the room faded rapidly, and dusk settled over the great amphibian city beneath the giant dome, kept from total darkness by a silvery pervading light that Norman reflected must be the light from Earth"s great sphere. With the dusk"s coming the activities in the frog-city lessened greatly.
With dusk, too, frog-guards entered the room bearing long metal troughs filled with a red jellylike substance, that they placed on racks along the wall. As the guards withdrew the men in the room rushed toward the troughs, elbowing each other aside and striking each other to scoop up and eat as much of the red jelly as possible.
It was for all the world like the feeding of farm-animals, and Hackett and Norman so sickened at the sight that they had no heart to try the food. Sarja, though, had no such scruples and seemed to make a hearty meal at one of the troughs.
After the meal the green men sought the bunks and soon were stretched in sonorous slumber. It was, Norman reflected, exactly the existence of domesticated animals--to eat and sleep and give food to their masters. A deeper horror of the frog-men shook him, and a deeper determination to escape them. He waited until all in the room were sleeping before beckoning to Sarja and Hackett.
"Quiet now," he whispered to them. "If these others wake they"ll make such a clamor we won"t have a chance in the world. Ready, Sarja?"
