Devil Crystals of Arret Part 4

"Larry, the rocks under us are crumbling!" she cried. "We'll be hurled down into the pit!"

Even as she spoke, Powell felt the narrow strip of rock under them quiver and settle. He looked quickly down. All along its length, the narrow rocky projection, weakened by their weight, was breaking swiftly away from the pit's edge. And on the floor of the pit below them the two waiting Devil Crystals moved with musical, tinkling sounds as they waited restlessly for their prey to fall among them.

The horde of rat-men rallied and swept on forward in a wave that nothing could have stopped this time--but their charge was too late.

The entire rocky projection collapsed with a final sickening lurch, and slid to the pit's floor, carrying Joan and Powell with it in a miniature avalanche of rocky rubble.

Even in the chaos of their wild descent, Powell retained his grip upon the loaded automatic in his hand. They struck the bottom and staggered half-dazed to their feet, to confront the two crystalline monsters rocking on their rounded bases scarcely ten feet away.

The fatal cone-shaped projection was already beginning to form upon the silver-faceted side of the nearest Devil Crystal. Before the lance-like arm of crystal could flash outward, Powell sent two bullets crashing into the crystal's side just over the opalescent nucleus.

The leaden missiles caromed harmlessly off, as though they had struck armor-plate, but the nucleus clouded momentarily and the cone-shaped projection dissolved back into the side.

With lightning speed Powell shifted his aim to the other crystal just as its partly-formed arm was flashing toward them. His bullet crashed into the silvery side squarely over the nucleus. Again the bullet's effect was the same. This crystal nucleus clouded murkily, and the lance-like arm telescoped back into the faceted bulk.

But the effect of the bullets was only momentary. Swiftly the nuclei of both crystals cleared. A deep blue film, apparently protective in nature, formed between the outer wall and each nucleus. The cones budded, and again the arms started forth.

Powell fired again, and this time uselessly. His bullet struck squarely, but the shock of its impact was apparently nullified by the protective blue film. He emptied his gun in a last crashing fusillade, but without effect of any kind upon the film-guarded nuclei of the giant crystals.

Their forming arms never wavered as they came lancing forward with deadly accuracy straight toward Joan and Powell. In a last effort to save Joan from the terrible doom of the crystal lances as long as possible, Powell flung his own body as a shield in front of the half-fainting girl. The tip of one of the crystalline arms struck his chest with a crashing tinkle of musical gla.s.s.

Instantly the tip sprayed into a web of fine filaments that laced on around his body. A tinkling shock raced through his every nerve from the contact with the weird life force of the great crystal.

The arm began contracting. Powell was helpless against the terrific power of the slender, diamond-hard lance of crystal. He felt himself irresistibly drawn toward the silver-faceted wall of the Devil Crystal.

His senses reeled in the babel of alien sounds--the crashing, gla.s.s-like music of the crystalline monsters and the snarling, squealing, paean of jubilant triumph from the thousands of rat-men now lining the rim of the pit above.

Then suddenly the pit, the Devil Crystals, and everything else in the nightmare world of Arret was blotted out in a vast swirling cloud of pulsing roseate flame that seemed to sweep him bodily up into the air and whirl him dizzily around.

His dazed brain staggered from the shock of the cataclysmic force that was disintegrating an entire world around him, but through the utter chaos one thought rang clear and exultant in his consciousness.

Benjamin Marlowe had finally broadcast the recall wave!

For what seemed endless eons of time Powell hurried through a limitless universe of swirling, tinted fires, while vibrations of a mighty force tingled with poignant ecstasy in every atom of his body.

Then the eddying clouds of flame began to coalesce and solidify with startling suddenness. A moment later, like the abrupt lighting of a room when an electric switch is snapped, the mists vanished and Powell felt firm footing again under his feet. Around him were the familiar objects of Benjamin Marlowe's laboratory.

He was standing upon the floor-plate in the center of the area bounded by the banked green tubes, and beside him stood Joan, sobbing with relief at their last-minute rescue from the Devil Crystals of Arret. And over by the control panel of the recall mechanism was the slight figure of old Benjamin Marlowe, with a great joy now shining in his faded eyes.
