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 modificationsand 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 stuffhe 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, theattackers 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 theirflyers 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 foughtthe 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, puttingit 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 officer 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?
One of those figures got up stiffly, bent over the huddle still on the ground, and pulled at something. The wooden shaft of Shann's spear was wanly visible. And the form on the ground did not stir as that was jerked loose. The Throg leader dead? Shann hoped so. He slid his knife back into the sheath, tapped the hilt to make sure it was firmly in place, and crawled on. The river, twisting here and there, was a promising pool of dusky shadow ahead. The bank of willow-things was coming to an end, and none too soon. For when he glanced back again he saw another Throg run across the meadow, and he watched them lift their fellow, carrying him back to camp.
The Throgs might seem indestructible, but he had put an end to one, aided by luck and a very rough weapon. With that to bolster his self-confidence to a higher notch, Shann dropped by cautious degrees over the bank and down to the water's edge. When his boots splashed into the oily flood he began to tramp downstream, feeling the pull of the water, first ankle high and then about his calves. This early in the season they did hot have to fear floods, and hereabouts the stream was wide and shallow, save in mid-current at the center point.
Twice more he had to skirt patches of light plants, and once a young tree stood bathed in radiance with a pinkish tinge instead of the usual ghostly gray. Within the haze which tented the drooping branches, flitted small glittering,flying things; and the scent of its half-open buds was heavy on the air, neither pleasant nor unpleasant in Shann's nostrils, merely different.
He dared to whistle, a soft call he hoped would carry along the cut between the high banks. But, though he paused and listened until it seemed that every cell in his thin body was occupied in that act, he heard no answering call from the wolverines, nor any suggestion that either the animals or Thorvald were headed in the direction of the raft.
What was he going to do if none of the others joined him downstream? Thorvald had said not to linger there past daylight. Yet Shann knew that unless he actually sighted a Throg patrol splashing after him he would wait until he made sure of the others' fate. Both Taggi and Togi were as important to him as the Survey officer. Perhaps more so, he told himself now, because he understood them to a certain degree and found companionship in their undemanding company which he could not claim from the man.
WhydidThorvald insist upon their going on to the seashore? To Shann's mind his own first plan of holing up back in the eastern mountains was better. Those heights had as many hiding places as the fiord country. But Thorvald had suddenly become so set on this westward trek that he had given in. As much as he inwardly rebelled when he took them, he found himself obeying the older man's orders. It was only when he was alone, as now, that he began to question both Thorvald's motives and his authority.
Three sprigs of a light bush set in a triangle. Shann paused and then climbed out on the bank, shaking the water from his boots as Taggi might shake such drops from a furred limb. This was the sign they had set to mark their rendezvous point, but....
Shann whirled, drawing his stunner. The raft was a dark blob on the surface of the water some feet farther on. And now it was bobbing up and down violently. That was not the result of any normal tug of current. He heard an indignant squeal and relaxed with a little laugh. He need not haveworried about the wolverines; that bait had drawn them all right. Both of them were now engaged in eating, though they had to conduct their feast on the rather shaky foundation of the makeshift transport.
They paid no attention as he waded out, pulling at the anchor cord as he went. The wind must have carried his familiar scent to them. As the water climbed to his shoulders Shann put one hand on the outmost log of the raft. One of the animals snarled a warning at being disturbed. Or had that been at him?
Shann stood where he was, listening intently. Yes, there was a splashing sound from upstream. Whoever followed his own recent trail was taking no care to keep that pursuit a secret, and the pace of the newcomer was fast enough to spell trouble.
Throgs? Tensely the Terran waited for some reaction from the wolverines. He was sure that if the aliens had followed him, both animals would give warning. Save when they had gone wild upon hearing that strange wail from the camp, they avoided meeting the enemy.
But from all sounds the animals had not stopped feeding. So the other was no beetle-head. On the other hand, why would Thorvald so advertise his coming, unless the need for speed was greater than caution? Shann drew taut the mooring cord, bringing out his knife to saw through that tough length. A figure passed the three-sprig signal, ran onto the raft.
"Lantee?" The call came in a hoarse, demanding whisper.
"Here."
"Cut loose. We have to get out of here!"
Thorvald flung himself forward, and together the men scrambled up on the raft. The mangled carcass plunged into the water, dislodged by their efforts. But before the wolverines could follow it, the mooring vine snapped, and the river current took them. Feeling the raft sway and begin to spin, the wolverines whined, crouched in the middle of what now seemed a very frail craft.
Behind them, far away but too clear, sounded that eerie howling, topping the sigh of the night wind.
"I saw——" Thorvald gasped, pausing as if to catch full lungfuls of air to back his words, "they have a 'hound!' That's what you hear."
As the raft revolved slowly it also slipped downstream at a steadily increasing pace, for the current had them in hold. The wolverines pressed close to Shann until the musky scent of their fur, their animal warmth, enveloped him. One growled deep in its throat, perhaps in answer to that wind-borne wail.
"Hound?" Shann asked.
Beside him in the dark Thorvald was working loose one of the poles they had readied to help control the raft's voyaging. The current carried them along, but there was a need for those lengths of sapling to fend them free from rocks and water-buried snags.
"What hound?" the younger man demanded more sharply when there came no immediate answer.
"The Throgs' tracker. But why did they import one?" Thorvald's puzzlement was plain in his tone. He added a moment later, with some of his usual firmness, "We may be in for bad trouble now. Use of a hound means an attempt to take prisoners——"
"Then they do not know that we are here, as Terrans, I mean?"
Thorvald seemed to be sorting out his thoughts when he replied to that. "They could have brought a hound here just on chance that they might miss one of us in the initial mop-up. Or, if they believe we are natives, they could want a specimen for study."
"Wouldn't they just blast down Terrans on sight?"
Shann saw the dark blot which was Thorvald's head shake in negation.
"They might need a live Terran—badly and soon."
"Why?"
"To operate the camp call beam."
Shann's momentary bewilderment vanished. He knew enough of Survey procedure to guess the reason for such a move on the part of the aliens.
"The settler transport?"
"Yes, the ship. She won't planet here without the proper signal. And the Throgs can't give that. If they don't take her, their time's run out before they have even made a start here."
"But how could they know that the transport is nearly due? When we intercept their calls they're pure gibberish to us. Can they read our codes?"
"The supposition is that they can't. Only, concerning Throgs, all we know is supposition. Anyway, they do know the routine for establishing a Terran colony, and we can't alter that procedure except in small nonessentials," Thorvald said grimly. "If that transport doesn't pick up the proper signal to set down here on schedule, her captain will call in the patrol escort ... then exit one Throg base. But if the beetle-heads can trick the ship in and take her, then they'll have a clear five or six more months here to consolidate their own position. After that it would take more than just one patrol cruiser to clear Warlock; it will require a fleet. So the Throgs will have another world to play with, and an important one. This lies on a direct line between the Odin and Kulkulkan systems. A Throg base on such a trade route could eventually cut us right out of this quarter of the galaxy."
"So you think they want to capture us in order to bring the transport in?"
"By our type of reasoning, that would be a logical move—ifthey know we are here. They haven't too many of those hounds, and they don't risk them on petty jobs. I'd hoped we'd covered our trail well. But we had to risk that attack on the camp.... I needed the map case!" Again Thorvaldmight have been talking to himself. "Time ... and the right maps—" he brought his fist down on the raft, making the platform tremble—"that's what I have to have now."
Another patch of light-willows stretched along the river-banks, and as they sailed through that ribbon of ghostly radiance they could see each other's faces. Thorvald's was bleak, hard, his eyes on the stream behind them as if he expected at any moment to see a Throg emerge from the surface of the water.
"Suppose that thing—" Shann pointed upstream with his chin—"follows us? What is it anyway?" Hound suggested Terran dog, but he couldn't stretch his imagination to believe in a working co-operation between Throg and any mammal.
"A rather spectacular combination of toad and lizard, with a few other grisly touches, is about as close as you can get to a general description. And that won't be too accurate, because like the Throgs its remote ancestors must have been of the insect family. If the thing follows us, and I think we can be sure that it will, we'll have to take steps. There is always this advantage—those hounds cannot be controlled from a flyer, and the beetle-heads never take kindly to foot slogging. So we won't have to expect any speedy chase. If it slips its masters in rough country, we can try to ambush it." In the dim light Thorvald was frowning. "I flew over the territory ahead on two sweeps, and it is a queer mixture. If we can reach the rough country bordering the sea, we'll have won the first round. I don't believe that the Throgs will be in a hurry to track us in there. They'll try two alternatives to chasing us on foot. One, use their energy beams to rake any suspect valley, and since there are hundreds of valleys all pretty much alike, that will take some time. Or they can attempt to shake us out with a dumdum should they have one here, which I doubt."
Shann tensed. The stories of the effects of the Throg's dumdum weapon were anything but pretty.
"And to get a dumdum," Thorvald continued as if hewere discussing a purely theoretical matter and not a threat of something worse than death, "They'll have to bring in one of their major ships. Which they will hesitate to do with a cruiser near at hand. Our own danger spot now is the section we should strike soon after dawn tomorrow if the rate of this current is what I have timed it. There is a band of desert on this side of the mountains. The river gorge deepens there and the land is bare. Let them send a ship over and we could be as visible as if we were sending up flares——"
"How about taking cover now and going on only at night?" suggested Shann.
"Ordinarily, I'd say yes. But with time pressing us now, no. If we keep straight on, we could reach the foothills in about forty hours, maybe less. And we have to stay with the river. To strike across country there without good supplies and on foot is sheer folly."
Two days. With perhaps the Throgs unleashing their hound on land, combing from their flyers. With a desert.... Shann put out his hands to the wolverines. The prospect certainly didn't seem anywhere near as simple as it had the night before when Thorvald had planned this escape. But then the Survey officer had left out quite a few points which were not pertinent. Was he also leaving out other essentials? Shann wanted to ask, but somehow he could not.
After a while he dozed, his head resting on his knees. He awoke, roused out of a vivid dream, a dream so detailed and so deeply impressed in a picture on his mind that he was confused when he blinked at the riverbank visible in the half-light of early dawn.
Instead of that stretch of earth and ragged vegetation now gliding past him as the raft angled along, he should have been fronting a vast skull stark against the sky—a skull whose outlines were oddly inhuman, from whose eyeholes issued and returned flying things while its sharply protruding lower jaw was lapped by water. In color that skull had been a violent clash of blood-red and purple. Shann blinked again at the riverbank, seeing transposed on it still that ghostly hazeof bone-bare dome, cavernous eyeholes and nose slit, fanged jaws. That skull was a mountain, or a mountain was a skull—and it was important to him; he must locate it!
He moved stiffly, his legs and arms cramped but not cold. The wolverines stirred on either side of him. Thorvald continued to sleep, curled up beyond, the pole still clasped in his hands. A flat map case was slung by a strap about his neck, its thin envelope between his arm and his body as if for safekeeping. On the smooth flap was the Survey seal, and it was fastened with a finger lock.
Thorvald had lost some of the bright hard surface he had shown at the spaceport where Shann had first sighted him. There were hollows in his cheeks, sending into high relief those bone ridges beneath his eye sockets, giving him a faint resemblance to the skull of Shann's dream. His face was grimed, his field uniform stained and torn. Only his hair was as bright as ever.
Shann smeared the back of his hand across his own face, not doubting that he must present an even more disreputable appearance. He leaned forward cautiously to look into the water, but that surface was not quiet enough to act as a mirror.
Getting to his feet as the raft bobbed under his shift of weight, Shann studied the territory now about them. He could not match Thorvald's inches, just as he must have a third less bulk than the officer, but standing, he could sight something of what now lay beyond the rising banks of the cut. That grass which had been so thick in the meadowlands around the camp had thinned into separate clumps, pale lavender in color. And the scrawniness of stem and blade suggested dehydration and poor soil. The earth showing between those clumps was not of the usual blue, but pallid, too, bleached to gray, while the bushes along the stream's edge were few and smaller. They must have crossed the line into the desert Thorvald had promised.
Shann edged around to face west. There was light enough in the sky to sight tall black pyramids waiting. They had toreach those distant mountains, mountains whose feet on the other side were resting in sea water. He studied them carefully, surveying each peak he could separate from its fellows.
Did the skull lie among them? The conviction that the place he had seen in his dream was real, that it was to be found on Warlock, persisted. Not only was it a definite feature of the landscape somewhere in the wild places of this world, but it was also necessary for him to locate it. Why? Shann puzzled over that, with a growing uneasiness which was not quite fear, not yet, anyway.
Thorvald moved. The raft tilted and the wolverines became growly. Shann sat down, one hand out to the officer's shoulder in warning. Feeling that touch Thorvald shifted, one hand striking out blindly in a blow which Shann was just able to avoid while with the other he pinned the map case yet tighter to him.
"Take it easy!" Shann urged.
The other's eyelids flicked. He looked up, but not as if he saw Shann at all.
"The Cavern of the Veil——" he muttered. "Utgard...." Then his eyes did focus and he sat up, gazing around him with a frown.
"We're in the desert," Shann announced.
Thorvald got up, balancing on feet planted a little apart, looking to the faded expanse of the waste spreading from the river cut. He stared at the mountains before he squatted down to fumble with the lock of the map case.
The wolverines were growing restless, though they still did not try to move about too freely on the raft, greeting Shann with vocal complaint. He and Thorvald could satisfy their hunger with a handful of concentrates from the survival kit. But those dry tablets could not serve the animals. Shann studied the terrain with more knowledge than he had possessed a week earlier. This was not hunting land, but there remained the bounty of the river.
"We'll have to feed Taggi and Togi," he broke the silenceabruptly. "If we don't, they'll be into the river and off on their own."
Thorvald glanced up from one of the tough, thin sheets of map skin, again as if he had been drawn back from some distance. His eyes moved from Shann to the unpromising shore.
"How? With what?" he wanted to know. Then the real urgency of the situation must have penetrated his mental isolation. "You have an idea——?"
"There's those fish we found them eating back by the mountain stream," Shann said, recalling an incident of a few days earlier. "Rocks here, too, like those the fish were hiding under. Maybe we can locate some of them here."
He knew that Thorvald would be reluctant to work the raft in shore, to spare time for such hunting. But there would be no arguing with hungry wolverines, and he did not propose to lose the animals for the officer's whim.
However, Thorvald did not protest. They poled the raft out of the main pull of the current, sending it in toward the southern shore in the lee of a clump of light-willows. Shann scrambled ashore, the wolverines after him, sniffling along at his heels while he overturned likely looking rocks to unroof some odd underwater dwellings. The fish with the rudimentary legs were present and not agile enough even in their native element to avoid well-clawed paws which scooped them neatly out of the river shallows. There was also a sleek furred creature with a broad flat head and paddle-equipped forepaws, rather like a miniature seal, which Taggi appropriated before Shann had a chance to examine it closely. In fact, the wolverines wrought havoc along a half-mile section of bank before the Terran could coax them back to the raft.
As they hunted, Shann got a better idea of the land about the river. It was sere, the vegetation dwindling except for some rough spikes of things pushing through the parched ground like flayed fingers, their puffed redness in contrast to the usual amethystine coloring of Warlock's growing things.Under the climbing sun that whole stretch of country was revealed in a stark bareness which at first repelled, and then began to interest him.
He discovered Thorvald standing on the upper bluff, looking out toward the waiting mountains. The officer turned as Shann urged the wolverines to the raft, and when he jumped down the drop to join them, Shann saw he carried a map strip unrolled in his hand.
"The situation is not as good as we hoped," he told the younger man. "Well have to leave the river to cross the heights."
"Why?"
"There're rapids—bending in a falls." The officer squatted down, spreading out the strip and making stabs at it with a nervous finger tip. "Here we have to leave. This is all rough ground. But lying to the south there's a gap which may be a pass. This was made from an aerial survey."
Shann knew enough to realize to what extent such a guide could go wrong. Main features of the landscape would be clear enough from aloft, but there might be unsurmountable difficulties at ground level which were not distinguishable from the air. Yet Thorvald had planned this journey as if he had already explored their escape route and that it was as open and easy as a stroll down Tyr's main transport way. Why was it so necessary that they try to reach the sea? However, since he had no objection to voice except a dislike for indefinite information, Shann did not question the other's calm assumption of command, not yet, anyway.
As they embarked and worked back into the current, Shann studied his companion. Thorvald had freely listed the difficulties lying before them. Yet he did not seem in the least worried about their being able to win through to the sea—or if he was, his outer shell of unconcern remained uncracked. Before their first day together had ended, the younger Terran had learned that to Thorvald he was only another tool, to be used by the Survey officer in some project which the other believed of primary importance. And his resentment of thevaluation was under control so far. He valued Thorvald's knowledge, but the other's attitude chilled and rebuffed his need for something more than a half partnership of work.
Why had Thorvald come back to Warlock in the first place? And why had it been necessary for him to risk his life—perhaps more than his life if their theory was correct concerning the Throgs' wish to capture a Terran—to get that set of maps from the plundered camp? When he had first talked of that raid, his promised loot had been supplies to fill their daily needs; there had been no mention of maps. By all signs Thorvald was engaged on some mission. And what would happen if he, Shann, suddenly stopped being the other's obedient underling and demanded a few explanations here and now?
Only Shann knew enough about men to also know that he would not get any information out of Thorvald that the latter was not ready to give, and that such a showdown, coming prematurely, would only end in his own discomfiture. He smiled wryly now, remembering his emotions when he had first seen Ragnar Thorvald months ago. As if the officer ever considered the likes, dislikes—or dreams—of one Shann Lantee. No, reality and dreams seldom approached each other. Dreams....
"On any of those shoreline maps," he asked suddenly, "do they have marked a mountain shaped like a skull?"
Thorvald thrust with his pole. "Skull?" he repeated, a little absently, as he so often did in answer to Shann's questions unless they dealt with some currently important matter.
"A queer sort of skull," Shann said. Just as vividly as when he had first awakened, he could picture that skull mountain with the flying things about its eye sockets. And that, too, was odd; dream impressions usually faded with the passing of waking hours. "It has a protruding lower jaw and the waves wash that ... red-and-purple rock——"
"What?"
He had Thorvald's complete attention now.
"Where did you hear about it?" That demand followed quickly.
"I didn't hear about it. I dreamed of it last night. I stood there right in front of it. There were birds—or things flying like birds—going in and out of theeyeholes——"
"What else?" Thorvald leaned across his pole, his eyes alive, avid, as if he would pull the reply he wanted out of Shann by force.
"That was all I remember—the skull mountain." He did not add his other impression, that he was meant to find that skull, that hemustfind it.
"Nothing...." Thorvald paused, and then spoke slowly, with a visible reluctance. "Nothing else? No cavern with a green veil—a wide green veil—strung across it?"
Shann shook his head. "Just the skull mountain."
Thorvald looked as if he didn't quite believe that, but Shann's expression must have been convincing, for he laughed shortly.
"Well, there goes one nice neat theory up in smoke!" he commented. "No, your skull doesn't appear on any of our maps, and so probably my cavern does not exist either. They may both be smoke screens——"
"What——?" But Shann never finished that query.
A wind was rising in the desert to blow across the slit which held the river, carrying with it a fine shifting of sand which coasted down into the water as a gray haze, coating men, animals, and raft, and sighing as snow sighs when it falls.
Only that did not drown out another cry, a thin cry, diluted by the miles of land stretching behind them, but yet carrying that long ululating howl they had heard in the Throg camp. Thorvald grinned mirthlessly.
"The hound's on trail."
He bent to the pole, using it to aid the pace of the current. Shann, chilled in spite of the sun's heat, followed his example, wondering if time had ceased to fight on their side.
The sun was a harsh ball of heat baking the ground and then, in some odd manner, drawing back that same fieriness. In the coolness of the eastern mountains Shann would not have believed that Warlock could hold such heat. The men discarded their jackets early as they swung to dip the poles. But they dared not strip off the rest of their clothing lest their skin burn. And again gusts of wind now drove sand over the edge of the cut to blanket the water.
Shann wiped his eyes, pausing in his eternal push-push, to look at the rocks which they were passing in threatening proximity. For the slash which held the river had narrowed. And the rock of its walls was naked of earth, save for sheltered pockets holding the drift of sand dust, while boulders of all sizes cut into the path of the flowing water.
He had not been mistaken; they were going faster, faster even than their efforts with the poles would account for. With the narrowing of the bed of the stream, the current was taking on a new swiftness. Shann said as much and Thorvald nodded.
"We're approaching the first of the rapids."
"Where we get off and walk around," Shann croaked wearily. The dust gritted between his teeth, irritated his eyes. "Do we stay beside the river?"
"As long as we can," Thorvald replied somberly. "We have no way of transporting water."
Yes, a man could live on very slim rations of food, continue to beat his way over a bad trail if he had the concentrate tablets they carried. But there was no going without water, and in this heat such an effort would finish them quickly.Always they both listened for another cry from behind, a cry to tell them just how near the Throg hunting party had come.
"No Throg flyers yet," Shann observed. He had expected one of those black plates to come cruising the moment the hound had pointed the direction for their pursuers.
"Not in a storm such as this." Thorvald, without releasing his hold on the raft pole, pointed with his chin to the swirling haze cloaking the air above the cut walls. Here the river dug yet deeper into the beginning of a canyon. They could breathe better. The dust still sifted down but not as thickly as a half hour earlier. Though over their heads the sky was now a grayish lid, shutting out the sun, bringing a portion of coolness to the travelers.
The Survey officer glanced from side to side, watching the banks as if hunting for some special mark or sign. At last he used his pole as a pointer to indicate a rough pile of boulders ahead. Some former landslide had quarter dammed the river at that point, and the drift of seasonal floods was caught in and among the rocky pile to form a prickly peninsula.
"In there——"
They brought the raft to shore, fighting the faster current. The wolverines, who had been subdued by the heat and the dust, flung themselves to the rocks with the eagerness of passengers deserting a sinking ship for certain rescue. Thorvald settled the map case more securely between his arm and side before he took the same leap. When they were all ashore he prodded the raft out into the stream again, pushing the platform along until it was sucked by the current past the line of boulders.
"Listen!"
But Shann had already caught that distant rumble of sound. It was steady, beating like some giant drum. Certainly it did not herald a Throg ship in flight and it came from ahead, not from their back trail.
"Rapids ... perhaps even the falls," Thorvald interpretedthat faint thunder. "Now, let's see what kind of a road we can find here."
The tongue of boulders, spiked with driftwood, was firmly based against the wall of the cut. But it sloped up to within a few feet of the top of that gap, more than one landslide having contributed to its fashioning. The landing stage paralleled the river for perhaps some fifty feet. Beyond it water splashed a straight wall. They would have to climb and follow the stream along the top of the embankment, maybe being forced well away from the source of the water.
By unspoken consent they both knelt and drank deeply from their cupped hands, splashing more of the liquid over their heads, washing the dust from their skins. Then they began to climb the rough assent up which the wolverines had already vanished. The murk above them was less solid, but again the fine grit streaked their faces, embedding itself in their hair.
Shann paused to scrape a film of mud from his lips and chin. Then he made the last pull, bracing his slight body against the push of the wind he met there. A palm struck hard between his shoulders, nearly sending him sprawling. He had only wits enough left to recognize that as an order to get on, and he staggered ahead until rock arched over him and the sand drift was shut off.
His shoulder met solid stone, and having rubbed the sand from his eyes, Shann realized he was in a pocket in the cliff walls. Well overhead he caught a glimpse of natural amber sky through a slit, but here was a twilight which thickened into complete darkness.
There was no sign of wolverines. Thorvald moved along the pocket southward, and Shann followed him. Once more they faced a dead end. For the crevice, with the sheer descent to the river on the right, the cliff wall at its back, came to an abrupt stop in a drop which caught at Shann's stomach when he ventured to look down.
If some battleship of the interstellar fleet had aimed a force beam across the mountains of Warlock, cutting down to whatlay under the first envelope of planet-skin, perhaps the resulting wound might have resembled that slash. What had caused such a break between the height on which they stood and the much taller peak beyond, Shann could not guess. But it must have been a cataclysm of spectacular dimensions. There was certainly no descending to the bottom of that cut and reclimbing the rock face on the other side. The fugitives would either have to return to the river with all its ominous warnings of trouble to come, or find some other path across that gap which now provided such an effective barrier to the west.
"Down!" Just as Thorvald had pushed him out of the murk of the dust storm into the crevice, so now did that officer jerk Shann from his feet, forcing him to the floor of the half cave from which they had partially emerged.
A shadow moved across the bright band of sunlit sky.
"Back!" Thorvald caught at Shann again, his greater strength prevailing as he literally dragged the younger man into the dusk of the crevice. And he did not pause, nor allow Shann to do so, even when they were well undercover again. At last they reached the dark hole in the southern wall which they had passed earlier. And a push from Thorvald sent his companion into that.
Then a blow greater than any the Survey officer had aimed at him struck Shann. He was hurled against a rough wall with impetus enough to explode the air from his lungs, the ensuing pain so great that he feared his ribs had given under that thrust. Before his eyes fire lashed down the slit, searing him into temporary blindness. That flash was the last thing he remembered as thick darkness closed in, shutting him into the nothingness of unconsciousness.
It hurt to breathe; he was slowly aware first of that pain and then the fact that hewasbreathing, that he had to endure the pain for the sake of breath. His whole body was jarred into a dull torment as a weight pressed upon his twisted legs. Then strong animal breath puffed into his face. Shann lifted one hand by will power, touched thick fur, felt the rasp of a tongue laid wetly across his fingers.
Something close to terror engulfed him for a second or two when he knew that he could not see! The black about him was colored by jagged flashes of red which he somehow guessed were actually inside his eyes. He groped through that fire-pierced darkness. An animal whimper from the throat of the shaggy body pressed against him; he answered that movement.
"Taggi?"
The shove against him was almost enough to pin him once more to the wall, a painful crush on his aching ribs, as the wolverine responded to his name. That second nudge from the other side must be Togi's bid for attention.
But what had happened? Thorvald had hurled him back just after that shadow had swung over the ledge. That shadow! Shann's wits quickened as he tried to make sense of what he could remember. A Throg ship! Then that fiery lash which had cut after them could only have resulted from one of those energy bolts such as had wiped out the others of his kind at the camp. But he was still alive—!
"Thorvald?" He called through his personal darkness. When there was no answer, Shann called again, more urgently. Then he hunched forward on his hands and knees, pushing Taggi gently aside, running his hands over projecting rocks, uneven flooring.
His fingers touched what could only be cloth, before they met the warmth of flesh. And he half threw himself against the supine body of the Survey officer, groping awkwardly for heartbeat, for some sign that the other was still living.
"What——?" The one word came thickly, but Shann gave something close to a sob of relief as he caught the faint mutter. He squatted back on his heels, pressed his forearm against his aching eyes in a kind of fierce will to see.
Perhaps that pressure did relieve some of the blackout, for when he blinked again, the complete dark and the fiery trails had faded to gray, and he was sure he saw dimly a source of light to his left.
The Throg ship had fired upon them. But the aliens couldnot have used the full force of their weapon or neither of the Terrans would still be alive. Which meant, Shann's thoughts began to make sense—sense which brought apprehension—the Throgs probably intended to disable rather than kill. They wanted prisoners, just as Thorvald had warned.
How long did the Terrans have before the aliens would come to collect them? There was no fit landing place hereabouts for their flyer. The beetle-heads would have to set down at the edge of the desert land and climb the mountains on foot. And the Throgs were not good at that. So, the fugitives still had a measure of time.
Time to do what? The country itself held them securely captive. That drop to the southwest was one barrier. To retreat eastward would mean running straight into the hands of the hunters. To descend again to the river, their raft gone, was worse than useless. There was only this side pocket in which they sheltered. And once the Throgs arrived, they could scoop the Terrans out at their leisure, perhaps while stunned by a controlling energy beam.
"Taggi? Togi?" Shann was suddenly aware that he had not heard the wolverines for some time.
He was answered by a weirdly muffled call—from the south! Had the animals found a new exit? Was this niche more than just a niche? A cave of some length, or even a passage running back into the interior of the peaks? With that faint hope spurring him, Shann bent again over Thorvald, able now to make out the other's huddled form. Then he drew the torch from the inner loop of his coat and pressed the lowest stud.
His eyes smarted in answer to that light, watered until tears patterned the grime and dust on his cheeks. But he could make out what lay before them, a hole leading into the cliff face, the hole which might furnish the door to escape.
The Survey officer moved, levering himself up, his eyes screwed tightly shut.
"Lantee?"
"Here. And there's a tunnel—right behind you. The wolverines went that way...."
To his surprise there was a thin ghost of a smile on Thorvald's usually straight-lipped mouth. "And we'd better be away before visitors arrive?"
So he, too, must have thought his way through the sequence of past action to the same conclusion concerning the Throg movements.
"Can you see, Lantee?" The question was painfully casual, but a note in it, almost a reaching for reassurance, cut for the first time through the wall which had stood between them from their chance meeting by the wrecked ship.
"Better now. I couldn't when I first came to," Shann answered quickly.
Thorvald opened his eyes, but Shann guessed that he was as blind as he himself had been, He caught at the officer's nearer hand, drawing it to rest on his own belt.
"Grab hold!" Shann was giving the orders now. "By the look of that opening we had better try crawling. I've a torch on at low——"
"Good enough." The other's fingers fumbled on the band about Shann's slim waist until they gripped tight at his back. He started on into the opening, drawing Thorvald by that hold with him.
Luckily, they did not have to crawl far, for shortly past the entrance the fault or vein they were following became a passage high enough for even the tall Thorvald to travel without stooping. And then only a little later he released his hold on Shann, reporting he could now see well enough to manage on his own.
The torch beam caught on a wall and awoke from there a glitter which hurt their eyes—a green-gold cluster of crystals. Several feet on, there was another flash of embedded crystals. Those might promise priceless wealth, but neither Terran paused to examine them more closely or touch their surfaces. From time to time Shann whistled. And always he was answered by the wolverines, their calls coming from ahead. Sothe men continued to hope that they were not walking into a trap from which the Throgs could extract them.
"Snap off your torch a moment!" Thorvald ordered.
Shann obeyed. The subdued light vanished. Yet there was still light to be seen—ahead and above.
"Front door," Thorvald observed. "How do we get up?"
The torch showed them that, a narrow ladder of ledges branching off when the passage they followed took a turn to the left and east. Afterward Shann remembered that climb with wonder that they had actually made it, though their advance had been slow, passing the torch from one to another to make sure of their footing.
Shann was top man when a last spurt of effort enabled him to draw himself out into the open, his hands raw, his nails broken and torn. He sat there, stupefied with his own weariness, to stare about.
Thorvald called impatiently, and Shann reached for the torch to hold it for the officer. Then Thorvald crawled out; he, too, looked around in dull surprise.
On either side, peaks cut high into the amber of the sky. But this bowl in which the men had found refuge was rich in growing things. Though the trees were stunted, the grass grew almost as high here as it did on the meadows of the lowlands. Quartering the pocket valley, galloped the wolverines, expressing in that wild activity their delight in this freedom.
"Good campsite."
Thorvald shook his head. "We can't stay here."
And, to underline that gloomy prophesy, there issued from that hole through which they had just come, muffled and broken, but still threatening, the howl of the Throgs' hound.
The Survey officer caught the torch from Shann's hold and knelt to flash it into the interior of the passage. As the beam slowly circled that opening, he held out his other arm, measuring the size of the aperture.
"When that thing gets on a hot scent"—he snapped off the beam—"the beetle-heads won't be able to control it. There will be no reason for them to attempt to. Those hounds obeytheir first orders: kill—or capture. And I think this one operates on 'capture.' So they'll loose it to run ahead of their party."
"And we move to knock it out?" Shann relied now on the other's experience.
Thorvald rose. "It would need a blaster on full power to finish off a hound. No, we can't kill it. But we can make it a doorkeeper to our advantage." He trotted down into the valley, Shann beside him without understanding in the least, but aware that Thorvald did have some plan. The officer bent, searched the ground, and began to pull from under the loose surface dirt one of those nets of tough vines which they had used for cords. He thrust a double handful of this hasty harvest into Shann's hold with a single curt order: "Twist these together and make as thick a rope as you can!"
Shann twisted, discovering to his pleased surprise that under pressure the vines exuded a sticky purple sap which not only coated his hands, but also acted as an adhesive for the vines themselves so that his task was not nearly as formidable as it had first seemed. With his force ax Thorvald cut down two of the stunted trees and stripped them of branches, wedging the poles into the rocks about the entrance of the hole.
They were working against time, but on Thorvald's part with practiced efficiency. Twice more that cry of the hunter arose from the depths behind them. As the westering sun, almost down now, shone into the valley hollow Thorvald set up the frame of his trap.
"We can't knock it out, any more than we can knock out a Throg. But a beam from a stunner ought to slow it up long enough for this to work."
Taggi burst out of the grass, approaching the hole with purpose. And Togi was right at his heels. Both of them stared into that opening, drooling a little, the same eagerness in their pose as they had displayed when hunting. Shann remembered how that first howl of the Throg hound had drawn both animals to the edge of the occupied camp in spite of their marked distaste for its alien masters.
"They're after it too." He told Thorvald what he had noted on the night of their sortie.
"Maybe they can keep it occupied," the other commented. "But we don't want them to actually mix with it; that might be fatal."
A clamor broke out in the interior passage. Taggi snarled, backing away a few steps before he uttered his own war cry.
"Ready!" Thorvald jumped to the net slung from the poles; Shann raised his stunner.
Togi underlined her mate's challenge with a series of snarls rising in volume. There was a tearing, scrambling sound from within. Then Shann fired at the jack-in-the-box appearance of a monstrous head, and Thorvald released the deadfall.
The thing squalled. Ropes beat, growing taut. The wolverines backed from jaws which snapped fruitlessly. To Shann's relief the Terran animals appeared content to bait the now imprisoned—or collared—horror, without venturing to make any close attack.
But he reckoned that too soon. Perhaps the stunner had slowed up the hound's reflexes, for those jaws stilled with a last shattering snap, the toad-lizard mask—a head which was against all nature as the Terrans knew it—was quiet in the strangle leash of the rope, the rest of the body serving as a cork to fill the exit hole. Taggi had been waiting only for such a chance. He sprang, claws ready. And Togi went in after her mate to share the battle.
There was a small eruption of earth and stone as the hound came alive, fighting to reach its tormentors. The resulting din was deafening. Shann, avoiding by a hand's breadth a snap of jaws with power to crush his leg into bone powder and mangled flesh, cuffed Togi across her nose and buried his hands in the fur about Taggi's throat as he heaved the male wolverine back from the struggling monster. He shouted orders, and to his surprise Togi did obey, leaving him free to yank Taggi away. Perhaps neither wolverine had expected the full fury of the hound.
Though he suffered a slash across the back of one hand, delivered by the over-excited Taggi, in the end Shann was able to get both animals away from the hole, now corked so effectively by the slavering thing. Thorvald was actually laughing as he watched his younger companion in action.
"This ought to slow up the beetles! If they haul their little doggie back, it's apt to take out some of its rage on them, and I'd like to see them dig around it."
Considering that the monstrous head was swinging from side to side in a collar of what seemed to be immovable rocks, Shann thought Thorvald right. He went down on his knees beside the wolverines, soothing them with hand and voice, trying to get them to obey his orders willingly.
"Ha!" Thorvald brought his mud-stained hands together with a clap, the sharp sound attracting the attention of both animals.
Shann scrambled up, swung out his bleeding hand in thesimple motion which meant to hunt, being careful to signal down the valley westward. Taggi gave a last reluctant growl at the hound, to be answered by one of its ear-torturing howls, and then trotted off, Togi tagging behind.
Thorvald caught Shann's slashed hand, inspecting the bleeding cut. From the aid packet at his belt he brought out powder and a strip of protecting plasta-flesh to cleanse and bind the wound.
"You'll do," he commented. "But we'd better get out of here before full dark."
The small paradise of the valley was no safe campsite. It could not be so long as that monstrosity on the hillside behind them roared and howled its rage to the darkening sky. Trailing the wolverines, the men caught up with the animals drinking from a small spring and thankfully shared that water. Then they pushed on, not able to forget that somewhere in the peaks about must lurk the Throg flyer ready to attack on sight.
Only darkness could not be held off by the will of men. Here in the open there was no chance to use the torch. As long as they were within the valley boundaries the phosphorescent bushes marked a path. But by the coming of complete darkness they were once more out in a region of bare rock.
The wolverines had killed a brace of skitterers, consuming hide and soft bones as well as the meager flesh which was not enough to satisfy their hunger. However, to Shann's relief, they did not wander too far ahead. And as the men stopped at last on a ledge where a fall of rock gave them some limited shelter both animals crowded in against the humans, adding the heat of their bodies to the slight comfort of that cramped resting place.
From time to time Shann was startled out of a troubled half sleep by the howl of the hound. Luckily that sound never seemed any louder. If the Throgs had caught up with their hunter, and certainly they must have done so by now, they either could not, or would not free it from the trap. Shanndozed again, untroubled by any dreams, to awake hearing the shrieks of clak-claks. But when he studied the sky he was able to sight none of the cliff-dwelling Warlockian bats.
"More likely they are paying attention to our friend back in the valley," Thorvald said dryly, rightly reading Shann's glance to the clouds overhead. "Ought to keep them busy."
Clak-claks were meat eaters, only they preferred their chosen prey weak and easy to attack. The imprisoned hound would certainly attract their kind. And those shrill cries now belling through the mountain heights ought to draw everyone of their species within miles.
"There it is!" Thorvald, pulling himself to his feet by a rock handhold, gazed westward, his gaunt face eager.
Shann, expecting no less than a cruising Throg ship, searched for cover on their perch. Perhaps if they flattened themselves behind the fall of stones, they might be able to escape attention. Yet Thorvald made no move into hiding. And so Shann followed the line of the other's fixed stare.
Before and below them lay a maze of heights and valleys, sharp drops, and saw-toothed rises. But on the far rim of that section of badlands shone the green of a Warlockian sea rippling on to the only dimly seen horizon. They were now within sight of their goal.
Had they had one of the exploration sky-flitters from the overrun camp, they could have walked its beach sands within the hour. Instead, they fought their way through a Devil-designed country for the next two days. Twice they had narrow escapes from the Throg ship—or ships—which continued to sweep across the rugged line of the coast, and only a quick dive to cover, wasting precious time cowering like trapped animals, saved them from discovery. But at least the hound did not bay again on the tangled trail they left, and they hoped that the trap and the clak-claks had put that monster permanently out of service.
On the third day they came down to one of those fiords which tongued inland, fringing the coast. There had been no lack of hunting in the narrow valleys through which theyhad threaded, so both men and wolverines were well fed. Though animal fur wore better than the now tattered uniforms of the men.
"Now where?" Shann asked.
Would he now learn the purpose driving Thorvald on to this coastland? Certainly such broken country afforded good hiding, but no better concealment than the mountains of the interior.
The Survey officer turned slowly around on the shingle, studying the heights behind them as well as the angle of the inlet where the wavelets lapped almost at their battered boot tips. Opening his treasured map case, he began a patient checking of landmarks against several of the strips he carried. "We'll have to get on down to the true coast."
Shann leaned against the trunk of a conical branched mountain tree, pulling absently at the shreds of wine-colored bark being shed in seasonal change. The chill they had known in the upper valleys was succeeded here by a humid warmth. Spring was becoming a summer such as this northern continent knew. Even the fresh wind, blowing in from the outer sea, had already lost some of the bite they had felt two days before when its salt-laden mistiness had first struck them.
"Then what do we do there?" Shann persisted.
Thorvald brought over the map, his black-rimmed nail tracing a route down one of the fiords, slanting out to indicate a lace of islands extending in a beaded line across the sea.
"We head for these."
To Shann that made no sense at all. Those islands ... why, they would offer less chance of establishing a safe base than the broken land in which they now stood. Even the survey scouts had given those spots of sea-encircled earth the most cursory examination from the air.
"Why?" he asked bluntly. So far he had followed orders because they had for the most part made sense. But he was not giving obedience to Thorvald as a matter of rank alone.
"Because there is something out there, something whichmay make all the difference now. Warlock isn't an empty world."
Shann jerked free a long thong of loose bark, rolling it between his fingers. Had Thorvald cracked? He knew that the officer had disagreed with the findings of the team and had been an unconvinced minority of one who had refused to subscribe to the report that Warlock had no native intelligent life and therefore was ready and waiting for human settlement because it was technically an empty world. But to continue to cling to that belief without a single concrete proof was certainly a sign of mental imbalance.
And Thorvald was regarding him now with frowning impatience. You were supposed to humor delusions, weren't you? Only, could you surrender and humor a wild idea which might mean your death? If Thorvald wanted to go island-hopping in chance of discovering what never had existed, Shann need not accompany him. And if the officer tried to use force, well, Shann was armed with a stunner, and had, he believed, more control over the wolverines. Perhaps if he merely gave lip agreement to this project.... Only he didn't believe, noting the light deep in those gray eyes holding on him, that anybody could talk Thorvald out of this particular obsession.
"You don't believe me, do you?" The impatience arose hotly in that demand.
"Why shouldn't I?" Shann tried to temporize. "You've had a lot of exploration experience; you should know about such things. I don't pretend to be any authority."
Thorvald refolded the map and placed it in the case. Then he pulled at the sealing of his blouse, groping in an inner secret pocket. He uncurled his fingers to display his treasure.
On his palm lay a coin-shaped medallion, bone-white but possessing an odd luster which bone would not normally show. And it was carved. Shann put out a finger, though he had a strange reluctance to touch the object. When he did he experienced a sensation close to the tingle of a mild electricshock. And once he had made that contact, he was also impelled to pick up that disk and examine it more closely.
The carved pattern was very intricate and had been done with great delicacy and skill, though the whorls, oddly shaped knobs, ribbon tracings, made no connected design he could determine. After a moment or two of study, Shann became aware that his eyes, following those twists and twirls, were "fixed," that it required a distinct effort to look away from the thing. Feeling some of that same alarm as he had known when he first heard the wailing of the Throg hound, he let the disk fall back intoThorvald's hold, even more disturbed when he discovered that to relinquish his grasp required some exercise of will.
