“They couldn’t have been so very far behind us, after all,” Volmar commented. “And of course our friend the astronomer had told them how we invaded his observatory and dispossessed him.”
Roverton was considering the various instruments in the cupola with an estimating eye. Some of them were set in the floor by means of metal bars and pivots, but many others were detached or loosely mounted. He picked up a singular object consisting of no less than seven concave lenses framed among rods and wires of a malachite-colored metal. It was satisfyingly heavy and would make an effective missile.
“We can hold the stairs while the ammunition lasts,” he said.
Volmar was lifting a small armillary to try its weight. Between them, the men collected everything movable in a great pile at the stair-head. They had no sooner finished doing this, when the foremost of their pursuers came in sight. The winding steps were packed with these creatures, most of whom were furnished with anaesthetic rods, ignescent wands, and other odd weapons.
The men began to hurl their fantastic missiles at the throng—a barrage of metal orbs and mirrors, and queer-angled things which may have served the purpose of telescopes, eye-glasses, and spectroscopes. The front rows of assailants were driven back with crushed heads and broken limbs, and many were slain or paralyzed by their own weapons as they went down in a tangled mass that blocked the stairway.
In an orderly manner, seemingly unperturbed by all these casualties, the dwarfs proceeded to clear away their dead and wounded, and then came on as before. More were swept down by the remainder of the observatory’s detachable paraphernalia; and much havoc in particular was inflicted by two armillaries which Volmar raised in his arms and sent crashing into the vanward files.
The supply of missiles was now exhausted; but Roverton still retained his death-dealing wand, and Volmar had reserved a sort of lens-apparatus which he intended to use as a mace when their attackers came within reach.
With the same hideous, unhuman imperturbability, after halting long enough to remove the victims of that final barrage, the dwarfs resumed their advance, while the earth-men awaited them at the stair-head.
Roverton, quick-eared and alert, as he watched the thronging onset, was aware of an odd noise from behind, as if something had clashed lightly against the cupola. Turning, he perceived that an air-vessel, shaped somewhat in the fashion of a long, crescent-prowed barge, but without wings or any visible agency of levitation, had attached itself by coiling tendril-like chains to the cupola-columns, and was discharging a dozen dwarfs into the observatory.
Roverton called Volmar’s attention to the new danger.
“If you can hold the stairs, Captain, I’ll tend to these customers,” he said, and sprang to meet the invaders. These latter were furnished with weapons of a kind which the earth-men had not hitherto encountered—long, trumpet-like tubes, which they levelled immediately at Roverton. Their curling fingers played on certain knobs which studded the tubes, and from the mouth of each weapon there issued a jet of pearly vapor. All were aiming at Roverton’s head, and he surmised that the vapor was some sort of deadly gas or anaesthetic. The goggles of his mask were blinded by the fumes, and he could see nothing as he groped among the strange paraphernalia in the dome.
Tripping against some unseen object, and trying to save himself from a fall, he lurched forward and stepped down with a terrific jar on the broad central disk that was set below the floor-level.
Clear of the pearly fumes, which still played overhead, he saw his assailants for an instant, crowding toward him with their weird weapons, as he clutched with his free hand at one of the upright rods which rose from the disk. Then he heard Volmar cry out, and turned his head toward the Captain, jerking the rod involuntarily as he did so. He saw in the merest flash of time that Volmar had fallen, and was half-hidden by the dwarfs who thronged about him from the stairs. Then the scene vanished, as if a black curtain had rushed upward from it, and Roverton realized that the disk was dropping away beneath him with dizzy velocity in a long, dark shaft.
Chapter VI
He surmised that he was in a sort of elevator. The jerking of the rod as he steadied himself in turning toward Volmar had started its downward flight. The thing was falling like a plummet, and he clung to the rod to keep from striking the walls of the shaft.
Soon, in the darkness, there came a series of red flashes, almost merging with one another. These must indicate openings from the shaft into the various floors of the main building. Doubtless, by manipulating one or other of the rods, he could check or reverse his descent. For a moment, he thought of trying to do the latter. He would go back to the tower and die fighting beside the fallen Volmar. But Volmar was dead—and what was the use? Heart-sick, lost, unutterably confused and bewildered, he felt a black weariness descend upon him like the clinging of some material thing. His remaining will was broken, his initiative was crushed beneath it.
With a dull fatalism, a leaden despair, he watched the red flashes. There must be hundreds of them, he thought. He was plunging down to a world whose actual soil neither he nor any other man had yet trodden; before the end came, he would perhaps attain a glimpse of maddening, insuperable mysteries, and would pierce a little further among the all-encompassing terrors and perils of a hostile planet. He resigned himself. He was not yet weaponless, for the lethal wand, with its green cone glowing brightly in the darkness, was still clutched in his right hand.
Abruptly, with no noise or jarring, the elevator came to a full stop. Roverton’s limbs and body were inundated by a stream of saffron light which poured into the shaft through a low doorway. At the same time, his ears were assailed by a medley of rumbling sounds and deep metallic throbbings which appeared to come from all around him. He had the feeling that he was underground, that his descent had precipitated him from that topmost tower into the nether vaults of the colossal city.
Cautiously he stooped and squeezed himself through the opening, which could afford ample passage for beings like the opalescent dwarfs but was rather scanty for a full-grown earth-man. Blinking in the saffron brilliance, he peered about him on a chamber so enormous, of such indeterminate scope that it seemed to partake of infinitude. It was filled with gigantic engines that appeared to use and combine every possible geometric form in their overbeetling bulks of dark stone and burnished metal. The yellow light emanated from a sort of open vat or furnace in which was a glowing mass of molten substance. There were other flaming furnaces at intervals, and great red eyes that burned in many of the machines, pouring down a lurid effulgence.
From some of the mechanisms, huge, ramifying pipes went up and vanished in the darkness of a funnel-like dome. In the wildly flickering patches of light, and monstrous masses of shadow, Roverton saw dim, titanic figures, but did not realize at first that they were living beings. They were ten or twelve feet in height, and were strange and uncouth as the mechanisms which they tended. There were also two or three dwarfs among them, who appeared to be supervising their labors.
Roverton surmised that he had stumbled into a power-plant of some unknown kind. The giants, mayhaps, were members of a subject people enslaved by the dwarfs and compelled to toil in their subterranean vaults.
The nearest furnace, watched by a single giant, was fifty feet away, and its warder had his back to Roverton. Hoping to escape observation in the vastness and gloom of the chamber, the earth-man started to make his way toward certain of the towering mechanisms that were dark and seemingly untended. He had no idea where he was going or what he would find; and he had reached the exhaustion point, both physically and mentally. The drug injected by the dwarfs seemed to be dying out in his veins, and he tottered with an intermittent weakness. Also, he was stunned by the loss of Volmar, his Captain and comrade. His brain, his senses, his muscles, were no longer functioning normally. It did not even occur to him that he might have stayed in the elevator shaft and found his way back to some other level where escape would not offer so many hazards.
