of tone. Again the thing repeated the sounds, and this time Milton uttered an exclamation.
"He's speaking to us!" he cried. "Trying to speak the English that I taught them in our communication! I caught a word – listen…"
As the creature repeated the sounds, Randall and Lanier started to hear also vaguely expressed in that hissing voice familiar words: "You – are Milton and – others from – earth?"
Milton spoke very clearly and slowly to the creature: "We are those from earth," he said. "And you are the Martians with whom we have communicated?"
"We are those Martians," said the other's hissing voice slowly. "These" – he waved a taloned paw toward those behind him – "have charge of the matter-transmitter and receiver. I am of our ruler's council."
"Ruler?" Milton repeated. "A ruler of all Mars?"
"Of all Mars," the other said. "Our name for him would mean in your words the Martian Master. I am to take you to him."
Milton turned to the other two with face alight with excitement. "These Martians have some supreme ruler they call the Martian Master," he said quickly; "and we're to go before him. As the first visitors from earth we're of immense importance here."
As he spoke, the Martian official before them had uttered a hissing call, and in answer to it a long shape of shining metal raced into the vast hall and halted beside them. It was like a fifty-foot centipede of metal, its scores of supporting short legs actuated by some mechanism inside the cylindrical body. There was a transparent-walled control room at the front end of that body, and in it a Martian at the controls who snapped open a door from which a metal ladder automatically descended.
The Martian official gestured with a reptilian arm toward the ladder, and Milton and Lanier and Randall moved carefully out of the cube-chamber and across the floor to it, each of their steps being made a short leap forward by the lesser gravity of the smaller planet. They climbed up into the centipede-machine's control room, their guide following, and then as the door snapped shut, the operator of the thing pulled and turned the knob in his grasp and the long machine scuttled forward with amazing smoothness and speed.
In a moment it was out of the building and into the feeble sunlight of a broad metal-paved street. About them lay a Martian city, seen by their eager eyes for the first time. It was a city whose structures were giant metal cones like that from which they had just come, though none seemed as large as that titanic one. Throngs of the hideous crocodilian Martians were moving busily to and fro in the streets, while among them there scuttled and flashed numbers of the centipede-machines.
As their strange vehicle raced along, Randall saw that the conelike structures were for the most part divided into many levels, and that inside some could be glimpsed ranks of great mechanisms and hurrying Martians tending them. Away to their right across the vast forest of cones that was the city the sun's little disk was shining, and he glimpsed in that direction higher ground covered with a vast tangle of bright crimson jungle that sloped upward from a great, half-glimpsed waterway.
The Martian beside them saw the direction of his gaze and leaned toward him. "No Martians live there," he hissed slowly. "Martians live only in cities where canals meet."
"Then there's no life in those crimson jungles?" Randall asked, repeating the question a moment later more slowly.
"No Martians there, but life – living things," the other told him, searching for words. "But not intelligent, like Martians and you."
He turned to gaze ahead, then pointed. "The Martian Master's cone," he hissed.
The three saw that at the end of the broad metal street down which their vehicle was racing there loomed another titanic cone-structure, fully as large as the mighty one in which they first found themselves. As the centipede-machine swept up to its great door-opening and halted, they descended to the metal paving and then followed their reptilian guide through the opening.
They found themselves in a great hall in which scores of the Martians were coming and going. At the hall's end stood a row of what seemed guards, Martians grasping shining tubes such as they had already glimpsed. These gave way to allow their passage when their conductor uttered a hissing order, and then they were moving down a shorter hall at whose end also were guards. As these sprang aside before them, a great door of massive metal they guarded moved softly upward, disclosing a mighty circular hall or room inside. Their crocodilian guide turned to them.
"The hall of the Martian Master," he hissed.
They passed 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 masses who have waited for ages for that moment and who will begin then our conquest of the earth!
"Yes,
