Shann could see no reason for such a laborious process. If Thorvald did not want to use his ax, that was no reason that Shann could not put his heavy belt knife to work. He hesitated, ready to set the blade to the outer bark of the tree.
"Look—" again that impatient edge in the officer's tone, the need for explanation seeming to come very hard to the other—"sooner or later the Throgs might just trace us here and find this camp. If so, they are not going to discover any traces to label us Terran——"
"But who else could we be?" protested Shann. "There is no native race on Warlock."
Thorvald tossed his improvised stone ax from hand to hand.
"But do the Throgs know that?"
The implications, the possibilities, in that idea struck home to Shann. Now he began to understand what Thorvald might be planning.
"Now there is going to be a native race." Shann made a statement instead of a question and saw that the other was watching him with a new intentness, as if he had at last been recognized as a person instead of rank and file and very low rank at that—Survey personnel.
"There is going to be a native race," Thorvald affirmed.
Shann resheathed his knife and went to search the pond beach for a suitable stone to use in its place. Even so, he made harder work of the clumsy chopping than Thorvald had. He worried at one sapling after another until his hands were skinned and his breath came in painful gusts from under aching ribs. Thorvald had gone on to another task, ripping the end of a long tough vine from just under the powdery surface of the thick leaf masses fallen in other years.
With this the officer lashed together the tops of the poles, having planted their splintered butts in the ground, so that he achieved a crudely conical erection. Leafy branches were woven back and forth through this framework, with an entrance, through which one might crawl on hands and knees, left facing the lakeside. The shelter they completed was compact and efficient but totally unlike anything Shann had ever seen before, certainly far removed from the domes of the camp. He said so, nursing his raw hands.
"An old form," Thorvald replied, "native to a primitive race on Terra. Certainly the beetle-heads haven't come across its like before."
"Are we going to stay here? Otherwise it is pretty heavy work for one night's lodging."
Thorvald tested the shelter with a sharp shake. The matted leaves whispered, but the framework held.
"Stage dressing. No, we won't linger here. But it's evidence to support our play. Even a Throg isn't dense enough to believe that natives would make a cross-country trip without leaving evidence of their passing."
Shann sat down with a sigh he made no effort to suppress. He had a vision of Thorvald traveling southward, methodically erecting these huts here and there to confound Throgs who might not ever chance upon them. But already the Survey officer was busy with a new problem.
"We need weapons——"
"We have our stunners, a force ax, and our knives," Shann pointed out. He did not add, as he would have liked that they could have had a blaster.
"Native weapons," Thorvald countered with his usual snap. He went back to the beach and crawled about there, choosing and rejecting stones picked out of the gravel.
Shann scooped out a small pit just before their hut and set about the making of a pocket-sized fire. He was hungry and looked longingly now and again to the supply bag Thorvald had brought with him. Dared he rummage in that for rations? Surely the other would be carrying concentrates.
"Who taught you how to make a fire that way?" Thorvald was back from the pond, a selection of round stones about the size of his fist resting between his chest and his forearm.
"It's regulation, isn't it?" Shann countered defensively.
"It's regulation," Thorvald agreed. He set down his stones in a row and then tossed the supply bag over to his companion. "Too late to hunt tonight. But well have to go easy on those rations until we can get more."
"Where?" Did Thorvald know of some supply cache they could raid?
"From the Throgs," the other answered matter of factly.
"But they don't eat our kind of food...."
"All the more reason for them to leave the camp supplies untouched."
"The camp?"
For the first time Thorvald's lips curved in a shadow smile which was neither joyous nor warming. "A native raid on an invaders' camp. What could be more natural? And we'd better make it soon."
"But how can we?" To Shann what the other proposed was sheer madness.
"There was once an ancient service corps on Terra," Thorvald answered, "which had a motto something like this: 'The improbable we do at once; the impossible takes a little longer.' What did you think we were going to do? Sulk around out here in the bush and let the Throgs claim Warlock for one of their pirate bases without opposition?"
Since that was the only future Shann had visualized, he was ready enough to admit the truth, only some shade of tone in the officer's voice kept him from saying so aloud.
4. SORTIE
Five days later they came up from the south so that this time Shann's view of the Terran camp was from a different angle. At first sight there had been little change in the general scene. He wondered if the aliens were using the Terran dome shelters themselves. Even in the twilight it was easy to pick out such landmarks as the com dome with the shaft of a broadcaster spearing from its top and the greater bulk of the supply warehouse.
"Two of their small flyers down on the landing field...." Thorvald materialized from the shadow, his voice a thread of whisper.
By Shann's side the wolverines were moving restlessly. Since Taggi's attack on the Throg neither beast would venture near any site where they could scent the aliens. This was the nearest point to which the men could urge either animal, which was a disappointment, for the wolverines would have been an excellent addition to the surprise sortie they planned for tonight, halving the danger for the men.
Shann ran his fingers across the coarse fur on the animals' shoulders, exerting a light pressure to signal them to wait. But he was not sure of their obedience. The foray was a crazy idea, and Shann wondered again why he had agreed to it. Yet he had gone along with Thorvald, even suggested a few modifications and additions of his own, such as the contents of the crude leaf sack now resting between his knees.
Thorvald flitted away, seeking his own post to the west. Shann was still waiting for the other's signal when there arose from the camp a sound to chill the flesh of any listener, a wail which could not have come from the throat of any normal living thing, intelligent being or animal. Ululating in ear-torturing intensity, the cry sank to a faint, ominous echo of itself, to waver up the scale again.
The wolverines went mad. Shann had witnessed their quick kills in the wilds, but this stark ferocity of spitting, howling rage was new. They answered that challenge from the camp, streaking out from under his hands. Yet both animals skidded to a stop before they passed the first dome and were lost in the gloom. A spark glowed for an instant to his right; Thorvald was ready to go, so Shann had no time to try and recall the animals.
He fumbled for those balls of soaked moss in his leaf bag. The chemical smell from them blotted out that alien mustiness which the wind brought from the campsite. Shann readied the first sopping mess in his sling, snapped his fire sparker at it, and had the ball awhirl for a toss almost in one continuous movement. The moss burst into fire as it curved out and fell.
To a witness it might have seemed that the missile materialized out of the air, the effect being better than Shann had hoped.
A second ball for the sling—spark ... out ... down. The first had smashed on the ground near the dome of the com station, the force of impact flattening it into a round splatter of now fiercely burning material. And his second, carefully aimed, lit two feet beyond.
Another wail tearing at the nerves. Shann made a third throw, a fourth. He had an audience now. In the light of those pools of fire the Throgs were scuttling back and forth, their hunched bodies
casting weird shadows on the dome walls. They were making efforts to douse the fires, but Shann knew from careful experimentation that once ignited the stuff he had skimmed from the lip of one of the hot springs would go on burning as long as a fraction of its viscid substance remained unconsumed.
Now Thorvald had gone into action. A Throg suddenly halted, struggled frantically, and toppled over into the edge of a fire splotch, legs looped together by the coils of the curious weapon Thorvald had put together on their first night of partnership. Three round stones of comparable weight had each been fastened at the end of a vine cord, and those cords united at a center point. Thorvald had demonstrated the effectiveness of his creation by bringing down one of the small "deer" of the grasslands, an animal normally fleet enough to feel safe from both human and animal pursuit. And those weighted ropes now trapped the Throg with the same efficiency.
Having shot his last fireball, Shann ran swiftly to take up a new position, downgrade and to the east of the domes. Here he put into action another of the primitive weapons Thorvald had devised, a spear hurled with a throwing stick, giving it double range and twice as forceful penetration power. The spears themselves were hardly more than crudely shaped lengths of wood, their points charred in the fire. Perhaps these missiles could neither kill nor seriously wound. But more than one thudded home in a satisfactory fashion against the curving back carapace or the softer front parts of a Throg in a manner which certainly shook up and bruised the target. And one of Shann's victims went to the ground, to lie kicking in a way which suggested he had been more than just bruised.
Fireballs, spears.... Thorvald had moved too. And now down into the somewhat frantic melee of the aroused camp fell a shower of slim weighted reeds, each provided with a clay-ball head. The majority of those balls broke on landing as the Terrans had intended. So, through the beetle smell of the aliens, spread the acrid, throat-parching fumes of the hot spring water. Whether those fumes had the same effect upon Throg breathing apparatus as they did upon Terran, the attackers could not tell, but they hoped such a bombardment would add to the general confusion.
Shann began to space the hurling of his crude spears with more care, trying to place them with all the precision of aim he could muster. There was a limit to their amount of varied ammunition, although they had dedicated every waking moment of the past few days to manufacture and testing. Luckily the enemy had had none of their energy beams at the domes. And so far they had made no move to lift their flyers for retaliation blasts.
But the Throgs were pulling themselves into order. Blaster fire cut the dusk. Most of the aliens were now flat on the ground, sending a creeping line of fire into the perimeter of the camp area. A dark form moved between Shann and the nearest patch of burning moss. The Terran raised a spear to the ready before he caught a whiff of the pungent scent emitted by a wolverine hot with battle rage. He whistled coaxingly. With the Throgs eager to blast any moving thing, the animals were in danger if they prowled about the scene.
That blunt head moved. Shann caught the glint of eyes in a furred mask; it was either Taggi or his mate. Then a puff of mixed Throng and chemical scent from the camp must have reached the wolverine. The animal coughed and fled westward, passing Shann.
Had Thorvald had time and opportunity to make his planned raid on the supply dome? Time during such an embroilment was hard to measure, and Shann could not be sure. He began to count aloud, slowly, as they had agreed. When he reached one hundred he would begin his retreat; on two hundred he was to run for it, his goal the river a half mile from the camp.
The stream would take the fugitives to the sea where fiords cut the coastline into a ragged fringe offering a wealth of hiding places. Throgs seldom explored any territory on foot. For them to venture into that maze would be putting themselves at the mercy of the Terrans they hunted. And their flyers could comb the air above such a rocky wilderness without result.
Shann reached the count of one hundred. Twice a blaster bolt singed ground within distance close enough to make him wince, but most of the fire carried well above his head. All of his spears were gone, save for one he had kept, hoping for a last good target. One of the Throgs who appeared to be directing the fire of the others was facing Shann's position. And on pure chance that he might knock out that leader, Shann chose him for his victim.
The Terran had no illusions concerning his own marksmanship. The most he could hope for, he thought, was to have the primitive weapon thud home painfully on the other's armored hide. Perhaps, if he were very lucky, he could knock the other from his clawed feet. But that chance which hovers over any battlefield turned in Shann's favor. At just the right moment the Throg stretched his head up from the usual hunched position where the carapace extended over his wide shoulders to protect one of the alien's few vulnerable spots, the soft underside of his throat. And the fire-sharpened point of the spear went deep.
Throgs were mute, or at least none of them had ever uttered a vocal sound to be reported by Terrans. This one did not cry out. But he staggered forward, forelimbs up, clawed digits pulling at the wooden pin transfixing his throat just under the mandible-equipped jaw, holding his head at an unnatural angle. Without seeming to notice the others of his kind, the Throg came on at a shambling run, straight at Shann as if he could actually see through the dark and had marked down the Terran for personal vengeance. There was something so uncanny about that forward dash that Shann retreated. As his hand groped for the knife at his belt his boot heel caught in a tangle of weed and he struggled for balance. The wounded Throg, still pulling at the spear shaft protruding above the swelling barrel of his chest, pounded on.
Shann sprawled backward and was caught in the elastic embrace of a bush, so he did not strike the ground. He fought the grip of prickly branches and kicked to gain solid earth under his feet. Then again he heard that piercing wail from the camp, as chilling as it had been the first time. Spurred by that, he won free. But he could not turn his back on the wounded Throg, keeping rather a sidewise retreat.
Already the alien had reached the dark beyond the rim of the camp. His progress now was marked by the crashing through low brush. Two of the Throgs back on the firing line started up after their leader. Shann caught a whiff of their odor as the wounded alien advanced with the single-mindedness of a robot.
It would be best to head for the river. Tall grass twisted about the Terran's legs as he began to run. In spite of the gloom, he hesitated to cross that open space. At night Warlock's peculiar vegetation displayed a very alien attribute—ten ... twenty varieties of grass, plant, and tree emitted a wan phosphorescence, varying in degree, but affording each an aura of light. And the path before Shann now was dotted by splotches of that radiance, not as brilliant as the chemical-born flames the attackers had kindled in the camp, but as quick to betray the unwary who passed within their dim circles. And there had never been any reason to believe that Throg powers of sight were less than human; there was perhaps some evidence to the contrary. Shann crouched, charting the clumps ahead for a zigzag course which would take him to at least momentary safety in the river bed.
Perhaps a mile downstream was the transport the Terrans had cobbled together no earlier than this afternoon, a raft Thorvald had professed to believe would support them to the sea which lay some fifty Terran miles to the west. But now he had to cover that mile.
The wolverines? Thorvald? There was one lure which might draw the animals on to the rendezvous. Taggi had brought down a "deer" just before they had left the raft. And instead of allowing both beasts to feast at leisure, Shann had lashed the carcass to the shaky platform of wood and brush, putting it out to swing in the current, though still moored to the bank.
Wolverines always cached that part of the kill which they did not consume at the first eating, usually burying it. He had hoped that to leave the carcass in such a way would draw both animals back to the raft when they were hungry. And they had not fed particularly well that day.
Thorvald? Well, the Survey of
ficer had made it very plain during the past five days of what Shann had come to look upon as an uneasy partnership that he considered himself far abler to manage in the field, while he had grave doubts of Shann's efficiency in the direction of survival potential.
The Terran started along the pattern of retreat he had laid out to the river bed. His heart pounded as he ran, not because of the physical effort he was expending, but because again from the camp had come that blood-freezing howl. A lighter line marked the lip of the cut in which the stream was set, something he had not foreseen. He threw himself down to crawl the last few feet, hugging the earth.
That very pale luminescence was easily accounted for by what lay below. Shann licked his lips and tasted the sting of sap smeared on his face during his struggle with the bushes. While the strip of meadow behind him now had been spotted with light plants, the cut below showed an almost solid line of them stringing willow-wise along the water's edge. To go down at this point was simply to spotlight his presence for any Throg on his trail. He could only continue along the upper bank, hoping to finally find an end to the growth of luminescent vegetation below.
Shann was perhaps five yards from the point where he had come to the river, when a commotion behind made him freeze and turn his head cautiously. The camp was half hidden, and the fires there must be dying. But a twisting, struggling mass was rolling across the meadow in his general direction.
Thorvald fighting off an attack? The wolverines? Shann drew his legs under him, ready to erupt into a counter-offensive. He hesitated between drawing stunner or knife. In his brush with the injured Throg at the wreck the stunner had had little impression on the enemy. And now he wondered if his blade, though it was super-steel at its toughest, could pierce any joint in the armored bodies of the aliens.
There was surely a fight in progress. The whole crazily weaving blot collapsed and rolled down upon three bright light plants. Dull sheen of Throg casing was revealed ... no sign of fur, or flesh, or clothing. Two of the aliens battling? But why?
