They pa.s.sed inside with him. The great hall seemed to extend upward to the giant cone's tip, thin light coming down from an opening there.

Upon the dull metal of its looming walls were running friezes of lighter metal, grotesque representations of reptilian shapes that they could but vaguely glimpse. Around the walls stood rank after rank of guards.

At the hall's center was a low dias, and in a semicircle around and behind it stood a half-hundred great crocodilian shapes. Randall guessed even at the moment that they were the council of which their conductor had named himself a member. But like Milton and Lanier, he had eyes in that first moment only for the dais itself. For on it was--the Martian Master.

Randall heard Milton and Lanier choke with the horror that shook his own heart and brain as he gazed. It was not simply another great crocodilian shape that sat upon that dais. It was a monstrous thing formed by the joining of three of the great reptilian bodies! Three distinct crocodile-like bodies sitting close together upon a metal seat, that had but a single great head. A great, grotesque crocodilian head that bulged backward and to either side, and that rested on the three thick short necks that rose from the triple body! And that head, that triple-bodied thing, was living, its unwinking eyes gazing at the three men!

The Martian Master! Randall felt his brain reel as he gazed at that mind-shattering thing. The Martian Master--this great head with three bodies! Reason told Randall, even as he strove for sanity, that the thing was but logical, that even on earth biologists had formed multiple-headed creatures by surgery, and that the Martians had done so to combine in one great head, one great brain, the brains of three bodies. Reason told him that the great triple brain inside that bulging head needed the bloodstreams of all three bodies to nourish it, must be a giant intellect indeed, one fitted to be the supreme Martian Master. But reason could not overcome the horror that choked him as he gazed at the awful thing.

A hissing voice sounding before him made him aware that the Martian Master was speaking.

"You are the Earth-beings with whom we communicated, and whom we instructed to build a matter-transmitter and receiver on earth?" the slow voice asked. "You have come safely to Mars by means of that station?"

"We have come safely." Milton's voice was shaken and he could find no other words.

"That is well. Long had we desired to have such a station built on earth, since with it there to flash back and forth between the two worlds is easy. You have come, then, to learn of this world and to take back what you learn to your races?"

"That is why we came." Milton said, more steadily. "We want to stay only hours on this first visit, and then flash back to earth as we came."

The head's awful eyes seemed to consider them. "But when do you intend to go back?" its strange voice asked. "Unless the one at your earth station has its receiver operating at the right moment you will simply flash on endlessly as radio waves--will be annihilated."

Milton found the courage to smile. "We started from earth at our midnight exactly, and at midnight exactly twenty-four earth hours later, we are to flash back and the receiver will be awaiting us."

There was silence when he had said that, a silence that seemed to Randall's strained mind to have become suddenly tense, sinister. The great triple-bodied creature before them considered them again, its eyes moving over them, and when it again spoke the hissing words came very slowly.

"Twenty-four earth hours," it said; "and then your receiver on earth will be awaiting you. That time we can measure to the moment, and that is well. For it is not you three Earth-beings who will flash back to earth when that moment comes! It will be Martians, the first of our Martian ma.s.ses who have waited for ages for that moment and who will begin then our conquest of the earth!

"Yes, Earth-beings, our great plan comes to its end now at last! At last! Age on age, prisoned on this dying, arid world, we have desired the earth that by right of power shall be ours, have sought for ages to communicate with its beings. You finally heard us, you hearkened to us, you built the matter-transmitting and receiving station on earth that was the one thing needed for our plan. For when the matter-receiver of that station is turned on in twenty-four of your hours, and ready to receive matter flashes from here, it will be the first of our millions who will flash at last to earth!

"I, the Martian Master, say it. Those first to go shall seize that matter-receiver on earth when first they appear there, shall build other and larger receivers, and through them within days all our Martian hordes shall have been flashed to earth! Shall have poured out over it and conquered with our weapons your weak races of Earth-beings, who cannot stand before us, and whose world you have delivered at last into our hands!"

For a moment, when the great monster's hissing voice had ceased, Milton and Randall and Lanier gazed toward it as though petrified, the whole unearthly scene spinning about them. And then, through the thick silence, the thin sound of Milton's voice:

"Our world--our earth--delivered to the Martians, and by us! G.o.d--no!"

With that last cry of agonized comprehension and horror, Milton did what surely had never any in the great hall expected, leaped onto the dais with a single spring toward the Martian Master! Randall heard a hundred wild hissing cries break from about him, saw the crocodilian forms of guards and council rushing forward even as he and Lanier sprang after Milton, and then glimpsed shining tubes levelled from which brilliant shafts of dazzling crimson light or force were stabbing toward them!

To Randall the moment that followed was but a split-second flash and whirl of action. As his earthly muscles took him forward with Lanier after Milton in a great leap to the dais, he was aware of the brilliant red rays stabbing behind him closely, and knew that only the tremendous size of his leap had taken him past them. In the succeeding instant he was made aware of what he had escaped, for the hastily-loosed rays struck squarely a group of three or four Martian guards rushing to the dais from the opposite side, and they vanished from view with a sharp detonation as though clicked out of existence!

Randall was not to know then, that the red rays were ones that annihilated matter by neutralizing or damping the matter-vibrations in the ether. But he did know that no more rays were loosed, for by then he and Milton and Lanier were on the dais and were wrapped in a hurricane combat with the guards that had rushed between them and the Martian Master.

Gleaming fangs--great scaled forms--reaching talons--it was all a wild phantasmagoria of grotesque forms spinning around him as he struck with all the power of his earthly muscles and felt crocodilian forms staggering and going down beneath his frenzied blows. He heard the roar of an automatic close beside him in the melee as Milton remembered at last through the red haze of his fury the weapon he carried, but before either Randall or Lanier could reach their own weapons a new wave of crocodilian forms had poured onto them that by sheer pressing weight held them helpless, to be disarmed.

Hissing orders sounded, the arms and legs of the three were tightly grasped by great taloned paws, and the ma.s.ses of Martians about them melted back from the dais. Held each by two great creatures, Milton and Randall and Lanier faced again the triple-bodied Martian Master, who in all that wild moment of struggle appeared not to have changed his position. The big monster's black eyes stared unmovedly down at them.

"You Earth-beings seem of lower intelligence even than we thought,"

his hissing voice informed them. "And those weapons--crude, very crude."

Milton, his face set, spoke back: "It may be that you will find human weapons of some power if your hordes reach earth," he said.

"But what compared with the power of ours?" the other asked coldly.

"And since our scientists even now devise new weapons to annihilate the earth's races, I think they would be glad of three of those races to experiment with now. The one use we can make of you, certainly."

The creature turned its bulging head a little towards the guards who held the three men, and uttered a brief hissing order. Instantly the six Martians, grasping the three tightly, marched them across the great hall and through a different door than that by which they had entered.

They were taken down a narrow corridor that turned sharply twice as they went on. Randall saw that it was lit by squares inset in the walls that glowed with crimson light. It came to him as they marched on that night must be upon the Martian city without, since the sun had been sinking when they had crossed it in the centipede-machine.

Through what seemed an ante-room they were taken, and then into a long hall instantly recognizable as a laboratory. There were many glowing squares illuminating it, and narrow windows high in the wall gave them a glimpse of the city outside, a pattern of crimson lights. Long metal tables and racks filled the big room's farther end, while along the walls were ranged shining mechanisms of unfamiliar and grotesque appearance. Fully a score of the crocodilian Martians were busy in the room, some intent on their work at the racks and tables, others operating some of the strange machines.

The guards conducted the three to an open s.p.a.ce by the wall, below one of the high window-openings and between two great cylindrical mechanisms. Then, while five of their number held the three men prisoned in that s.p.a.ce by the threat of their levelled ray-tubes, the other moved toward one of the busy Martian scientists and held with him a brief interchange of hissing speech.

Milton leaned to whisper to the other two: "We've got to get out of this while we're still living," he whispered. "You heard the Martian Master--in constructing that matter-receiver on earth, we've opened a door through which all the Martian millions will pour onto our world!"

"It's useless, Milton," said Randall dully. "Even if we got clear of this the Martians will be at their matter-transmitter in hordes when the moment comes to flash back to earth."

"I know that, but we've got to try," the other insisted. "If we or some of us could get clear of this, we might in some way hide near the matter-transmitter until the moment came and then fight to it."

"But how to get out of the hands of these, even?" asked Lanier, nodding toward the alert guards before them.

"There's but one way," Milton whispered swiftly. "Our earthly muscles would enable us, I think, to get through this window-opening above us in a leap, if we had a moment's chance. Well, whichever of us they take to experiment with or examine first, must make a struggle or disturbance that will turn the guards' attention for a moment and give the other two a chance to make the attempt!"

"One to stay and the other two to get away...." Randall said slowly; but Milton's tense whisper interrupted:

"It's the only way, and even then a thousand to one chance! But it's we who have opened this gate for the Martian invasion of our world and it's we who must--"

Before he could finish, the approach of hissing voices told them that the leader of the six guards and the Martian who seemed the chief of the experimenters in the hall were nearing them. The three men stood silent and tense as the two crocodilian monsters stopped before them.

The scientist, who carried in his metal-belt, instead of a ray-tube a compact case of instruments, surveyed them as though in curiosity.

He came closer, his quick reptilian eyes taking in with evident interest every feature of their bodily appearance. Intuitively the three knew that one of them was to be chosen for a first investigation by the Martian scientists, and that that one would have not even the slender hope of escape open to the other two. A strange lottery of life and death!

Randall saw the creature's gaze turn from one to another of them, and then heard the hiss of his voice as he pointed a taloned paw toward Milton. Instantly two of the guards had seized Milton and had jerked him out from the wall, the other guards holding back Randall and Lanier with threatening tubes. It was upon Milton that the fatal choice had fallen!

Randall and Lanier made together a half-movement forward, but Milton, a tense message in his eyes, forced them back. The guards who held the physicist led him, at the direction of the Martian scientist, toward a great upright frame at the room's far end, upon which were cl.u.s.tered a score of dial-indicators. From these flexible cords led; and now the scientists began attaching these by clips to various spots on Milton's body. Some mechanical examination of his bodily characteristics were apparently to be made. Milton shot suddenly a glance at the two by the wall, and his head nodded in an almost imperceptible signal. The muscles of Lanier and Randall tensed.

Then abruptly Milton seemed to go mad. He shouted aloud in a terrible voice, and at the same moment tore from him the cords just attached, his fists striking out then at the amazed Martians around him. As they leaped back from that sudden explosion of activity and sound on Milton's part the guards before Randall and Lanier whirled instinctively for an instant toward it. And in that instant the two had leaped.
