Various - Astounding Stories, April, 1931

"A canal!" cried Lanier. "It's one of the canals that meet at this city and flow around it! We're trapped – we've reached the city's edge!"

"Not yet!" Randall gasped. "Look!"

As he pointed to the left Lanier shot a glance there; and then both of them were running in that direction, along the smooth metal paving that bordered the mighty canal. They came to what Randall had seen, a mighty metal arch that soared out over the waterway to its opposite side. A bridge!

They were on it, were racing up the smooth incline of it. Randall glanced back as they reached the arch's summit. From that height the city stretched far away behind them, a lace of crimson lights in the night. He glimpsed the gleam of the giant waterway that encircled the city completely, one that was fed by other canals from far away that emptied into it, the great city's vital water-supply brought thus from this world's melting polar snows.

There were moving lights behind now, too, pouring out onto the metal paving by the waterway, moving to and fro as though in confusion, with a babel of hissing cries. It was not until Randall and Lanier were running down the descending incline of the great arched bridge, though, that the lights and shouts of their pursuers began to move up on that bridge after them.

Running off the bridge's smooth way, the two found themselves stumbling on through the darkness over more metal paving, and then over soft ground. There were no lights or buildings or sounds of any sort on this farther side of the great waterway. A tall dark wall seemed suddenly to loom up out of the darkness some distance ahead of the two.

"The crimson jungle!" Randall cried. "The jungles we glimpsed from the city! It's a chance to hide!"

They raced toward the protecting blackness of that wall of vegetation. They reached it, flung themselves inside, just as the pursuing Martians, a mass of running crocodilian shapes and of great racing centipede-machines, swept up over the bridge's arch behind. A moment the two halted in the thick vegetation's shelter, gasping for breath, then were moving forward through the jungle's denser darkness.

Thick about them and far above them towered the masses of strange trees and plant life through which they made their way. Randall could see but dimly the nature of these plant-forms, but could make out that they were grotesque and unearthly in appearance, all leafless, and with masses of thin tendrils branching from them instead of leaves. He realized that it was only beside the arid planet's great canals that this profusion of plant life had sufficient moisture for existence, and that it was the broad bands of jungle bordering the canals that had made the latter visible to earth's astronomers.

Lanier and he halted for a moment to listen. The thick jungle about them seemed quite silent. But from behind there came through it a vague tumult of hissing calls; and then, as they glimpsed red flashes far behind, they heard the crashing of great masses of the leafless trees.

"The rays!" whispered Lanier. "They're beating through the jungle with them and the centipede-machines after us!"

They paused no more, but pushed on through the thick growths with renewed urgency. Now and then, as they passed through small clearings, Randall glimpsed overhead the fast-moving nearer moon and slower sailing farther moon of Mars, moving across the steady stars. In some of these clearings they saw, too, strange great openings burrowed in the ground as though by some strange animal.

The crashing clamor of the Martians beating the jungle behind was coming close, ever closer, and as they came to still another misty-lit clearing, Lanier paused, with face white and tense.

"They're closing in on us!" he said. "They're hunting us down by beating the jungle with those centipede-machines, and even if we escape them we're getting farther from the city and the matter-station each moment!"

Randall's eyes roved desperately around the clearing; and then, as they fell on a group of the great burrowed openings that seemed present everywhere about them, he uttered an exclamation.

"These holes! We can hide in one until they've passed over us, and then steal back to the city!"

Lanier's eyes lit. "It's a chance!"

They sprang toward the openings. They were each of some four feet diameter, extending indefinitely downward as though the mouths of tunnels. In a moment Randall was lowering himself into one, Lanier after him. The tunnel in which they were, they found, curved to one side a few feet below the surface. They crawled down this curve until they were out of sight of the opening above. They crouched silent, then, listening.

There came down to them the dull, distant clamor of the centipede-machines crashing through the jungle, cutting a way with rays, their clamor growing ever louder. Then Randall, who was lowest in the tunnel, turned suddenly as there came to him a strange rustling sound from beneath him. It was as though some crawling or creeping thing was moving in the tunnel below them!

He grasped the arm of Lanier, beside and a little above him, to warn him, but the words he was about to whisper never were uttered. For at this moment a big shapeless living thing seemed to flash up toward them through the darkness from beneath, cold ropelike tentacles gripped both tightly; and then in an instant they were being dragged irresistibly down into the lightless tunnel's depths!

As they were pulled swiftly downward into the tunnel by the tentacles that grasped them an involuntary cry of horror came from Randall and Lanier alike. They twisted frantically in the cold grip that held them, but found it of the quality of steel. And as Randall twisted in it to strike frantically down through the darkness at whatever thing of horror held them, his clenched fist met but the cold smooth skin of some big, soft-bodied creature!

Down – down – remorselessly they were being drawn farther into the black depths of the tunnel by the great thing crawling down below them. Again and again the two twisted and struck, but could not shake its hold. In sheer exhaustion they ceased to struggle, dragged helplessly farther down.

Was it minutes or hours, Randall wondered afterward, of that horrible progress downward, that passed before they glimpsed light beneath? A feeble glow, hardly discernible, it was, and as they went lower still he saw that it was caused by the tunnel passing through a strata of radio-active rock that gave off the faint light. In that light they glimpsed for the first time the horror dragging them downward.

It was a huge worm creature! A thing like a giant angleworm, three feet or more in thickness and thrice that in length, its great body soft and cold and worm-like. From the end nearest them projected two long tentacles with which it had gripped the two men and was dragging them down the tunnel after it! Randall glimpsed a mouth-aperture in the tentacled end of the worm body also, and two scarlike marks above it, placed like eyes, although eyes the monstrous thing had not.

But a moment they glimpsed it and then were in darkness again as the tunnel passed through the radio-active strata and lower. The horror of that moment's glimpse, though, made them strike out in blind repulsion, but relentlessly the creature dragged them after it.

"God!" It was Lanier's panting cry as they were dragged on. "This worm monster – we're hundreds of feet below the surface!"

Randall sought to reply, but his voice choked. The air about them was close and damp, with an overpowering earthy smell. He felt consciousness leaving him.

A gleam of soft light – they were passing more radio-active patches. He felt the wild convulsive struggles of Lanier against the thing; and then suddenly the tunnel ended, debouched into a far-stretching, low-ceilinged cavity. It was feebly illuminated by radio-active patches here and there in walls and ceiling, and as the monster that held them halted on entering the cavity, Randall and Lanier lay in its grip and stared across the weird place with intensified horror.
