by Unknown
Harkness glanced quickly about to size up their situation. To go on was certain death; if these creatures came up to meet them on the lava-beds, the end was sure. The escarpment gave the three some slight advantage of a higher position.
One vain wish for the pistol now resting in the deep grass beside a vanished ship; then he sprang for the weapon that had been thrown--it was better than nothing--and advanced cautiously to the lava's edge.
No concealment there; no broken rocks, other than pieces of flint; a poor fortress, this, that they must defend! And the weapons of their civilization were denied them.
Another spear hummed its shrill song, coming dangerously close. He saw women-figures that came from the jungle with supplies of weapons. Short spears, about six feet long, like the one he held. But they had others, too--long lances of slender wood with tips of flint. Thrusting spears! He had a sickening vision of those jagged stone heads ripping into their bodies while these beasts stood off in safety. It was thus that they killed their prey. And Diane--he could not even spare her--could not give her the kind oblivion of a mercy-shot!
The other two were lying beside him now at the edge of the sloping cliff. The bank of shining gray was not steep; the enemy would climb it with ease. Hopeless! They had won through for this!... Harkness groaned silently in an agony of spirit at thought of the girl.
"Oh, for one detonite shell to land among them!" he said between clenched teeth--then was breathless with a thought that exploded within his mind.
* * * * *
His fingers were clumsy with haste as he fumbled at the head of the spear. The sharp-edged stone was bound to its shaft with sinew, wound round and round. The enemy were out in the open; he spared an instant's look to see them advancing. A clattering of falling spears sounded beyond, but the weapons were overcast, thanks to the protection of the rocky edge.
"A shell!" Harkness spoke with sharp intensity. "Give me a cartridge from your belt, quick!"
Chet handed him one. Harkness took one look, then pulled a cartridge from his own belt.
"That explains it," he was muttering as he worked, "--the big explosion when I smashed the rocks. You've got ammunition for your pistol, but you put rifle cartridges in my belt--and service ammunition at that. No wonder they raised the devil with those rocks!"
His fingers were working swiftly now to bind the slender cartridge to the spear. A chipped out hollow in the flint made a seat. He gave silent thanks for Chet Bullard's mistake. Chet had slipped; he had filled Harkness' belt with ammunition that would have been useless for the pistol--but it was just what he needed here.
So intent was he on his task that he hardly heard the yelling chorus from below. It swelled to a din; but his work was finished, and he looked up.
One figure in advance of the rest had been urging them on, and they came in a wild rush now. Walt Harkness scrambled to his feet. Tall and sinewy, his broad shoulders, scantily covered by the rags of blouse that remained, were turned sideways as he raised the spear. The yelling from below swelled louder and more shrill.
This strange one from another tribe--he was unarmed except for one of their own spears. The curious covering on his body was flapping in the breeze. Nothing here, surely, to hold a hunting-tribe in check.
The spear rose slowly in the air. What child of the tribe could not have thrown it better! They came on faster now; the leader had almost reached the place where the spear was dropping down. He must have laughed, if laughter had yet been born in such a breast, at the futile weapon dropping point first among the rocks.
One little shell, a scant three inches long, no thicker than the stylus on milady's desk! But here was service ammunition, as Harkness had said; and in the end of the lead a fulminate cap was buried--and a grain of dense, gray dust!
* * * * *
There was no flame--only a concussion that cracked upon one's ears, and flying rock fragments that filled the air with demoniac shrieks. And then that sound was lost in the shriller cries of terror and pain as the ape-men broke for the trees.
Harkness saw some of them who rose and fell again to rise no more, and one who dragged himself slowly from the blast that had struck him down. But his eyes came back to another spear in his hands, and his fingers were tearing at the sinew wrapping.
The spear bent in his hands; the wood was flexible and springy. It was Diane who offered the next suggestion. She, too, was working at another spear--what wonder if her breath came fast!--but her eyes were alight, and her mind was at work.
"Make a bow!" she exclaimed. "A bow and arrow, Walter! We are fighting primitive men, so we can't scorn primitive weapons." She stopped with a little exclamation of pain; the sharp tip of the flint had cut her hand.
Chet's spearhead was unloosed. He tried the spring of the shaft. "Bully girl, Diane!" he said, and fell to gouging out a notch with the sharp flint near the end of the shaft.
The sinew made a string. Three slender sticks lying about whose ends had been sharpened for use on the meat: they would do for arrows. Each arrow must be notched and headed with an explosive shell, and there were many of them.
Chet sprang to his feet at last. Forgotten was the fatigue that had numbed him. A wild figure, his clothes in rags, his short, curling hair no longer blond, his face a mottling of brown and black, where only here and there the white skin dared show through--he executed an intricate dance-step with a bed of lava for a floor, while he shouted:
"Bring on your fighters! Bring 'em on! Who's going to stop us now?"
* * * * *
They were free to go, but Harkness paused at a renewed screaming from the jungle. Again the hairy ones poured forth into the open glade. He had half raised his bow, with arrow ready, before he saw that this was no attack.
The screams merged discordantly with other sounds--a crashing of uprooted trees--a chorus of harsh coughing--snorting--unrecognizable noises. And the people were cowering in terror.
They half-ran toward the safety of their caves, but the throwers of thunder, the demons on the lava bed, were between them and their homes. They turned to face the jungle, and the wild sounds and crash of splintered wood that drew near.
Harkness saw the first head that appeared. He stared in open-mouthed amazement at the armored monster. Thick plates of shell covered its mammoth body and lapped part way over the head to end at beady, wicked, red eyes on either side of a single curved horn.
An instant the animal waited, to glare at the cowering human forms it had tracked to their lair; others crashed through beside it; and in that instant Harkness recognized the huddled group below as brothers. Far down they were, in the long, weary path that was evolution, and hardly come as yet to a consciousness of self--but there were those who leaped before the others, their long spears couched and ready; they were defending the weaker ones at their backs; they were men!
And Harkness was shouting as he raised his crude bow. "Shoot!" he ordered. "Kill the brutes!" His own arrow was speeding true.
The rush of mammoth beasts was on as he fired, but it was checked as quickly as it began. An inferno of explosions rose about the rushing bodies; crashing detonations struck two of them down, their heads torn and crushed. Between the helpless, primordial men and the charging beasts was a geyser of spouting earth and rocks, through which showed ugly heads and tremendous bodies that wheeled and crashed madly back into the jungle growth.
Harkness suddenly realized that only he and Chet had fired. Diane's bow was on the ground. He saw the girl beside it, sitting upright; but her body was trembling and weaving, and she was plainly maintaining her upright posture only by the greatest effort.
* * * * *
He was beside her in an instant. "What is it?" he demanded. "Are you hurt? What is it?"
She raised her hand that he might see; her lips, seemed almost too numb for speech.
"Only a scratch," she whispered, but Harkness saw her eyes glazing. He dropped to his knees and caught her swaying body in his arms.
"A scratch," s
he repeated in a fading voice, "from the spear.... Poison ... I think."
A head appeared over the lava crest. Harkness saw it vaguely. He knew that Chet had the newcomer covered; his bow was drawn. It meant nothing to him, for Diane was wounded--dying! Dying, now, in his arms....
The ape-man came on; he was grovelling upon the ground. He was hairless, like the one they had seen escape the attack of the giant bat, and his cheek was slashed with a healing cut that might have been made by a ripping talon. He abased himself before the awful might of these creatures who had saved them. And he made motions with his arms to picture how they had sailed down from the skies; had landed; and he had seen them. He was plainly petitioning for pardon and the favor of these gods--when he dropped his animal head to stare at the girl and the cut hand that Harkness held in his.
The blue discoloration of the wound must have been plain in its significance. The hairless one sprang abruptly to his feet and darted toward a cave. He was back in a moment; and, though be approached with wriggling humility, he reached the girl and he ventured to touch the discolored hand with a sticky paste. He had a gourd that he held to the girl's lips.
Harkness would have struck it away; he was beside himself with grief. But Chet interposed.
"Give it to her," he said in a sharp, strained voice that told of his own dismay. "I think the beggar knows what he's about. He is trying to help."
The lips were lax; only a little of the liquid found its way down her throat. But Harkness, after minutes of agony, saw the first flutter of lids that betokened returning life....
CHAPTER X - "But Awfully Dumb...."
Harkness would never forget the helpless body in his arms, nor the tender look that came slowly to the opened eyes that gazed so steadily into his. And yet it was Chet that she seemed to want for the thousand little services during the week that followed. And Harkness tried to still the hurt in his heart, and he told himself that it was her happiness be wanted more than his; that if she found greater pleasure in having Chet near, then his love was unworthy if it placed itself as a bar to that other happiness.
He talked by signs with the hairless one whom he called Towahg. It was the sound the other made as he struck upon his chest. And he learned that Towahg could guide him to the ship.
The tribe had left them alone. Only Towahg seemed inclined to friendliness; and Harkness frequently saw the one who was their leader in ugly, silent contemplation of them when Towahg brought food and water to their cave.
Diane was recovering, but her progress was slow. She was able at once to walk and go slowly about, but the least exertion tired her. It had been a close call, Harkness knew, and he realized that some time must pass before she could take up the hardships of the trail. And in the meantime much might happen.
He felt that he must reach the ship at the first possible moment and return for the others; Towahg would show him the way. He explained the plan to Chet and Diane only to meet with emphatic dissent.
"You would go alone?" the girl exclaimed. "To meet heaven knows what dangers? No, no, Walter; you must not! Wait; I am stronger; I can go soon, I know."
Chet, too, was for delay--Diane was better, and she would improve steadily. They could carry her, at first. But Harkness looked at the jungle he must penetrate and knew that he was right.
* * * * *
He gave Towahg a bow and arrows like his own and those that Chet kept for defense, but the arrows were of sharpened wood without detonite tips. He grinned toward Chet as he showed the savage how to handle the marvellous thing.
"We've advanced these people a thousand years in the science of arms," he said. "They should make Diane their first Minister of Munitions, or worship her as their own lovely goddess of the chase."
A weapon that would throw farther than the strongest man could cast a spear--here was magic indeed! And Towahg knelt and grovelled on the ground at his benefactor's feet.
Harkness made light of the dangers he must face, but he knew in his own mind he might fail. And the time of leaving found him curiously depressed. He had gripped Chet's hand, then turned to Diane for what might be a last good-by. The quick enfoldment of her soft body in his arms was as unpremeditated as the kiss he placed upon her lips.... He swung away abruptly, and fell in behind his guide without a word. The way led first across the place of smoke and fire.
Danger ahead on this strange trail; he knew it well. But he took it as it came; and his guide, and his crude weapon, and his steady eye and sureness of foot on rocky crags all saw him through. And he mentally mapped the hills and valleys and the outcrops of metals that he would explore some later time. Only seven of the short six-hour days of this little earth had passed when he drew near the ship.
He was ready for an attack. There was the broken rubble that marked the entrance of the cave. Beneath it, he knew, were mangled, horrible remains. This one beast alone, it seemed, had been the ruler of the valley, for no other appeared.
The mass that had blocked the doorway was crystalline now, and broke to brittle fragments at a blow. He entered the familiar cabin of the ship. There was nothing disturbed; the sealed inner door had barred entrance to any inquiring beasts.
Far down the valley he saw a naked, running figure. Towahg had escorted this sky-god to the great bird that had brought him, but the courage of even so advanced a tribesman as he must have limits. He was still running along the path they had come when Harkness closed and sealed the door.
* * * * *
There was an instrument among their stores for taking samples of gas. Harkness attached it to the ship before he left, and he took a few precious minutes for a flight into the heights. That gas up there was fatal to the monsters of space: he must secure a sample and learn its composition.
A closing of the switch on wires that led to the instrument outside, and he knew that the container had emptied its contents of water, drawn in the gas and sealed itself.
Then the swift descent.
He flew low as he circled back. They had traveled far on their journey below ground; it was even a longer route where he and Towahg had circled about. But it was the only route he knew; he could take no chances on a short-cut and a possible long-drawn search for the little valley.
He followed the trail. The quick dusk was near; but in an hour's slow flying, while his eyes searched the hills and hollows, the valley was in sight.
He came down slowly in a black sky, with only the soft, muffled roar of the lower exhausts. It was growing dark, and he leaned from an open door to see more clearly his position. All was different from the air, and he needed time and careful scrutiny to get the bearings of the place.
The soft thunder from below was in his ears when a sound pierced through. His own name! And it was Diane's voice calling him in a terrified tone.
"Walter!" she cried. "Help! Help! Oh, Walter, come quickly!"
* * * * *
The scene below was lighted by fitful fires. He was above the upper valley, a hundred yards from their cave: his mind was oriented in an instant, and he knew each foot of ground.
And here, where neither Diane nor Chet should be, was Diane. He saw her running in the bright glare of his landing light that he now switched on; saw a black shape hurl itself upon her; she was struggling. He threw himself back at the controls to send the ship like a thunderbolt upon the earth.
A pistol was in his hand as he leaped from the still-rocking ship and threw himself upon the thing that ran and tried to carry a struggling burden in its arms.
He could not fire; but he brought the pistol down upon a heavy skull. The hairy figure seemed never to feel the blow. It dropped the body of Diane and turned, and its slavering, shining fangs were set in a horrible face that Harkness recognized.
It was the leader of the tribe, and he had dared to attack. But where was Chet? What of his arrows and their detonite tips? These thoughts were crowding through his mind in the instant that ape-like fingers gripped at his throat--the instant while he was bringing the pistol forward
and up.
A light charge of detonite in pistol ammunition--but no living body could withstand the shock. Harkness leaped over the fallen foe to reach the girl. She was half risen to a sitting posture as he came.
"Dieu!" she was whispering; "Ah, le bon Dieu!" Then she cried out: "Walter! Oh, Walter, they have killed Chet! Down there!" Her hand was pointing. She grasped at Harkness' hand to draw herself to her feet and race with him toward the cave.
* * * * *
"Just at dark," she explained gaspingly as they ran. "It was their chief, and there were others with him. They leaped upon Chet--before he could reach for his bow. They had seemed so friendly after you left--but they were short of food--"
Her voice was sobbing now, but she kept on, and she set a pace that Harkness could not outdistance.
"One aimed a spear at me, and Chet threw himself between. I saw the spear strike--then I ran. I thought I heard your motors--I screamed for you--"
They were nearing the caves. A fire was burning in the open glade where grotesque figures leaped and danced in cannibal glee about a figure that lay motionless upon the ground.
The tattered, wind-blown clothing--the curling hair, blond in the fire's light--it was Chet.... And now Harkness could fire.
His pistol held twenty rounds. He emptied it into the shrieking group, then jammed in more of the shells and fired again. He fired until no target remained, and every savage figure was either vanished among the trees or inert and lifeless upon the ground, their only motion the stirring of their hairy coverings in the breeze.
* * * * *
Harkness was beside the prostrate figure. He raised Chet's head within his arms; Diane's brown head leaned close, her gasping breath broken by dry sobs. The firelight flickered upon the closed lids to give them semblance of life.
