And, in spite of their efforts, the party was being herded into a pocket between the jungle below, where the main body of graz crashed along, and a steep wall. Given time to find the necessary finger and toe holds, a man might climb that wall, but they could not attempt it now. The portion of ledge on which they ran, stopped to fire, and then ran on again, angled to the southeast. And so they came to its end quickly, a drop ending in a plain of yellow-gray mud studded with clumps of bleached vegetation which led, like steppingstones, toward a tangle of matted, sickly looking plants and reeds.
"All right," Tau faced around, "what do we do now? Space lift? And using what for wings or jets?"
As if the graz could sense that they now had their victims safely cornered, what must have been a goodly segment of the herd hooked their way from the jungle and started up. Puffing, digging in those sturdy legs which had to take the massive weight of their barrel-shaped bodies, they made their way determinedly up-grade. One might almost believe that they had intelligently planned this end for their drive.
"We go down!" Asaki yelled, and used his needler on the leader of that climbing platoon.
"The brush islands," Nymani amended. "I show you!" He thrust his needler at Jellico and was over the edge of the ledge, hanging by his hands and swinging his weight back and forth like a pendulum. At the up-swing of his body to the right, he let go and plunged out, landing half across one of the reed islets. The Khatkan clawed his way to his knees, gained his feet, and leaped for the next bit of solid ground.
"You, Thorson!" Jellico jerked his head at Dane and the younger spaceman holstered his fire ray, slipped gingerly over the drop and prepared to repeat Nymani's feat as best he could.
He was not quite as successful with his sidewise swing, landing with only his forearms across the islet, the rest of his body being swiftly embedded in what was ooze covered only with a thin crust of dried matter. The stench of the stuff was sickening, but the fear of being entrapped in it gave him the necessary impetus to push forward, though what was meant to be a swift half-dive was more of a worm's progress. He grabbed frantically at brittle stems, at coarse grass which cut like knives at his hands. But some of the material held and he lay face down on a lump which did not give under his weight.
There was no time to linger; he had to get to the next patch, to free this dubious landing place for the men embattled on the rise above. Stumbling up, Dane judged the distance with a space-trained eye and jumped to a knob Nymani had already quitted. The Khatkan was more than halfway along toward that promise of solid ground which the tangled mass of leprous vegetation led to, zigzagging expertly from islet to islet.
There was a crash and a roar behind. Dane balanced on the third of the minute islands to look back. He saw the lash of blaster fire on the top of the cliff, Tau on his knees on the first of their chain of steppingstones, and a graz sprawled head and forequarters in the sucking muck where it had dived past the two defenders above. Needler and blaster fired together again, and then Jellico swung over the cliff rim. Tau waved vigorously and Dane took off for the next islet, just making it by lucky chance.
The rest of the journey he took in a rush, trying not to think of anything but the necessity of landing on some spot of firm ground. His last leap of all was too short, so that he went knee deep in a particularly evil-smelling pool where yellow scum spattered his breeches and he experienced the insidious pull of the bottomless stuff. A stout branch whipped across his shoulder and he caught it. With Nymani's wiry strength on the other end, Dane worked free and sat, white-faced and shivering, on a mat of brush, while the Khatkan hunter turned his attention to the safety of Tau, the next arrival.
More fortunate, or more skillful than Dane, the medic made the hop from the last tuft without mishap. But he was blowing heavily as he collapsed beside the other spaceman. Together they watched the progress of their captain.
Safe on the second tussock from the shore, Jellico halted, edged carefully around and used the needler Nymani had left with him. A shaggy head tossed and the bull fronting Asaki on the cliff went down. The Chief Ranger dodged quickly to the right and a second beast rushed out and over, to join its mired comrade in the swamp below. As Jellico shot again, the Khatkan slung his needler and went over to gain the first islet.
One more graz was wounded but luckily it hunched about, turning its formidable tusks on those that followed, thus keeping the path clear for its enemies. Jellico was making the journey, sure-footedly, with the Chief Ranger only one hillock behind. Tau sighed.
"Someday maybe this will be just another tall tale and we'll all be thought liars when we spout it," he observed. "That is if we survive to tell it. So now which way do we go? If I had my choice it would be up!"
When Dane pulled himself to his feet and surveyed their small refuge, he was ready to agree to that. For the space, packed with dead and dying vegetable matter until one sank calf deep, was a triangle with a narrow point running east into the swamp.
"They don't give up easily, do they?" Jellico looked back to the shore and the cliff. Though the wounded graz bull still held the heights against its fellows, there were others breaking from the jungle on the lower level, wandering back and forth to paw the earth, rip up soil with their tusks, and otherwise threaten anyone who would try to return to the strip they patrolled.
"They will not," Asaki answered bleakly. "Arouse a graz and it will trail you for days; kill any of the herd and you have little hope of escaping them on foot."
It would seem now that the swamp was a deterrent to pursuit. The two beasts that had fallen in the mire moaned in a pitiful rising note. They had ceased to struggle and several of their kind clustered on the shore near them, calling entreatingly. Asaki took careful aim with the needler and put one animal after another out of its misery. But the flash of those shots angered those on shore to a higher pitch of rage.
"No going back," he said. "At least not for several days."
Tau slapped a black, four-winged insect which had settled on his arm, its jaws wide open for a sampling bite. "We can't very well perch here until they forget all about us," he pointed out. "Not without water we can trust, and with the local wild life ready to test us for tasty eating."
Nymani had prowled along the swampward point of their island, and now he made his report.
"There is more high land to the east. Perhaps it will give us a bridge across."
At that moment Dane doubted his ability to make any more leaps from island to island. And it would seem Tau shared his discouragement.
"I don't suppose you could discourage our friends on shore there with a few more shots?"
Asaki shook his head. "We do not have clips enough to settle a whole herd. These might retreat from sight but they would be waiting for us in the bush, and that would mean certain death. We shall have to take the swamp road."
If Dane had considered their earlier march misery, this was sheer torture. Since footing was never secure, falls were frequent, and within a quarter-hour they were all plastered with evil-smelling slime and mud which hardened to rock consistency when exposed to the air. Painful as this was, it did protect a portion of their bodies from the insects with which the swamp was well stocked.
And, in spite of their efforts to find a way out, the only possible paths led them deeper into the center of the unexplored morass. At last Asaki called a halt and a council to consider retreat. To locate an island from which they could at least watch the shore appealed very strongly indeed.
"We have to have water." Tau's voice was a harsh croak, issuing out of a mask of green mud festooned with trailing weeds.
"This ground is rising." Asaki smacked the stock of his needler against the surface on which he crouched. "I think perhaps there may be clean land soon to come."
