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.
6 : THE HOUND
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 tedious push-push, to look at the rocks which they were passing in risky 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 interpreted that 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 ascent 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 rubbing 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 the 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 halt 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 what lay under the first layer 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 under cover 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 he was breathing, 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.
