The native took the arrow and examined it. "Not my tribe."

"Of course not your tribe. Yours wouldn't take a shot at us. Some

other tribe, perhaps?"

"Very poor arrow."

"I know that. But it could kill you just as dead as if it were a good

one. Do you recognize it?"

"No tribe made this arrow," Sipar declared.

"Child, maybe?"

"What would child do way out here?"

[Illustration]

"That's what I thought, too," said Duncan.

* * * * *

He took the arrow back, held it between his thumbs and forefingers and

twirled it slowly, with a terrifying thought nibbling at his brain. It

couldn't be. It was too fantastic. He wondered if the sun was finally

getting him that he had thought of it at all.

He squatted down and dug at the ground with the makeshift arrow point.

"Sipar, what do you actually know about the Cytha?"

"Nothing, mister. Scared of it is all."

"We aren't turning back. If there's something that you know--something

that would help us...."

It was as close as he could come to begging aid. It was further than

he had meant to go. He should not have asked at all, he thought

angrily.

"I do not know," the native said.

Duncan cast the arrow to one side and rose to his feet. He cradled the

rifle in his arm. "Let's go."

He watched Sipar trot ahead. Crafty little stinker, he told himself.

It knows more than it's telling.

They toiled into the afternoon. It was, if possible, hotter and drier

than the day before. There was a sense of tension in the air--no, that

was rot. And even if there were, a man must act as if it were not

there. If he let himself fall prey to every mood out in this empty

land, he only had himself to blame for whatever happened to him.

The tracking was harder now. The day before, the Cytha had only run

away, straight-line fleeing to keep ahead of them, to stay out of

their reach. Now it was becoming tricky. It backtracked often in an

attempt to throw them off. Twice in the afternoon, the trail blanked

out entirely and it was only after long searching that Sipar picked it

up again--in one instance, a mile away from where it had vanished in

thin air.

That vanishing bothered Duncan more than he would admit. Trails do not

disappear entirely, not when the terrain remains the same, not when

the weather is unchanged. Something was going on, something, perhaps,

that Sipar knew far more about than it was willing to divulge.

He watched the native closely and there seemed nothing suspicious. It

continued at its work. It was, for all to see, the good and faithful

hound.

* * * * *

Late in the afternoon, the plain on which they had been traveling

suddenly dropped away. They stood poised on the brink of a great

escarpment and looked far out to great tangled forests and a flowing

river.

It was like suddenly coming into another and beautiful room that one

had not expected.

This was new land, never seen before by any Earthman. For no one had

ever mentioned that somewhere to the west a forest lay beyond the

bush. Men coming in from space had seen it, probably, but only as a

different color-marking on the planet. To them, it made no difference.

But to the men who lived on Layard, to the planter and the trader, the

prospector and the hunter, it was important. And I, thought Duncan

with a sense of triumph, am the man who found it.

"Mister!"

"Now what?"

"Out there. _Skun!_"

"I don't--"

"Out there, mister. Across the river."

Duncan saw it then--a haze in the blueness of the rift--a puff of

copper moving very fast, and as he watched, he heard the far-off

keening of the storm, a shiver in the air rather than a sound.

He watched in fascination as it moved along the river and saw the

boiling fury it made out of the forest. It struck and crossed the

river, and the river for a moment seemed to stand on end, with a sheet

of silvery water splashed toward the sky.

Then it was gone as quickly as it had happened, but there was a

tumbled slash across the forest where the churning winds had traveled.

Back at the farm, Zikkara had warned him of the _skun_. This was the

season for them, it had said, and a man caught in one wouldn't have a

chance.

Duncan let his breath out slowly.

"Bad," said Sipar.

"Yes, very bad."

"Hit fast. No warning."

"What about the trail?" asked Duncan. "Did the Cytha--"

Sipar nodded downward.

"Can we make it before nightfall?"

"I think so," Sipar answered.

It was rougher than they had thought. Twice they went down blind

trails that pinched off, with sheer rock faces opening out into drops

of hundreds of feet, and were forced to climb again and find another

way.

They reached the bottom of the escarpment as the brief twilight closed

in and they hurried to gather firewood. There was no water, but a

little was still left in their canteens and they made do with that.

* * * * *

After their scant meal of rockahominy, Sipar rolled himself into a

ball and went to sleep immediately.

Duncan sat with his back against a boulder which one day, long ago,

had fallen from the slope above them, but was now half buried in the

soil that through the ages had kept sifting down.

Two days gone, he told himself.

Was there, after all, some truth in the whispered tales that made the

rounds back at the settlements--that no one should waste his time in

tracking down a Cytha, since a Cytha was unkillable?

Nonsense, he told himself. And yet the hunt had toughened, the trail

become more difficult, the Cytha a much more cunning and elusive

quarry. Where it had run from them the day before, now it fought to

shake them off. And if it did that the second day, why had it not

tried to throw them off the first? And what about the third

day--tomorrow?

He shook his head. It seemed incredible that an animal would become

more formidable as the hunt progressed. But that seemed to be exactly

what had happened. More spooked, perhaps, more frightened--only the

Cytha did not act like a frightened beast. It was acting like an

animal that was gaining savvy and determination, and that was somehow

frightening.

From far off to the west, toward the forest and the river, came the

laughter and the howling of a pack of screamers. Duncan leaned his

rifle against the boulder and got up to pile more wood on the fire. He

stared out into the western darkness, listening to the racket. He made

a wry face and pushed a hand absent-mindedly through his hair. He put

out a silent hope that the screamers would decide to keep their

distance. They were something a man could do without.

Behind him, a pebble came bumping down the slope. It thudded to a rest

just short of the fire.

Duncan spun around. Foolish thing to do, he thought, to camp so near

the slope. If something big should start to move, they'd be out of

luck.

He stood and listened. The night was quiet. Even the screamers had

shut up for the moment. Just one rolling rock and he had his hackles

up. He'd have to get himself in hand.

He went back to the boulder, and as he stooped to pick up the rifle,

he heard the faint beginning of a rumble. He straightened swiftly to

face the scarp that blotted out the star-strewn sky--and the rumble

grew!

* * * * *

In one leap, he was at Sipar's side. He reached down and grasped the

native by an arm, jerked it erect, held it on its feet. Sipar's eyes

snapped open, blinking in the firelight.

The rumble had grown to a roar and there were thumping noises, as of

heavy boulders bouncing, and beneath the roar the silky, ominous

rustle of sliding soil and rock.

Sipar jerked its arm free of Duncan's grip and plunged into the

darkness. Duncan whirled and followed.

They ran, stumbling in the dark, and behind them the roar of the

sliding, bouncing rock became a throaty roll of thunder that filled

the night from brim to brim. As he ran, Duncan could feel, in dread

anticipation, the gusty breath of hurtling debris blowing on his neck,

the crushing impact of a boulder smashing into him, the engulfing

flood of tumbling talus snatching at his legs.

A puff of billowing dust came out and caught them and they ran choking

as well as stumbling. Off to the left of them, a mighty chunk of rock

chugged along the ground in jerky, almost reluctant fashion.

Then the thunder stopped and all one could hear was the small

slitherings of the lesser debris as it trickled down the slope.

Duncan stopped running and slowly turned around. The campfire was

gone, buried, no doubt, beneath tons of overlay, and the stars had

paled because of the great cloud of dust which still billowed up into

the sky.

He heard Sipar moving near him and reached out a hand, searching for

the tracker, not knowing exactly where it was. He found the native,

grasped it by the shoulder and pulled it up beside him.

Sipar was shivering.

"It's all right," said Duncan.

And it _was_ all right, he reassured himself. He still had the rifle.

The extra drum of ammunition and the knife were on his belt, the bag

of rockahominy in his pocket. The canteens were all they had lost--the

canteens and the fire.

"We'll have to hole up somewhere for the night," Duncan said. "There

are screamers on the loose."

* * * * *

He didn't like what he was thinking, nor the sharp edge of fear that

was beginning to crowd in upon him. He tried to shrug it off, but it

still stayed with him, just out of reach.

Sipar plucked at his elbow.

"Thorn thicket, mister. Over there. We could crawl inside. We would be

safe from screamers."

It was torture, but they made it.

"Screamers and you are taboo," said Duncan, suddenly remembering. "How

come you are afraid of them?"

"Afraid for you, mister, mostly. Afraid for myself just a little.

Screamers could forget. They might not recognize me until too late.

Safer here."

"I agree with you," said Duncan.

The screamers came and padded all about the thicket. The beasts

sniffed and clawed at the thorns to reach them, but finally went away.

When morning came, Duncan and Sipar climbed the scarp, clambering over

the boulders and the tons of soil and rock that covered their camping

place. Following the gash cut by the slide, they clambered up the

slope and finally reached the point of the slide's beginning.

There they found the depression in which the poised slab of rock had

rested and where the supporting soil had been dug away so that it

could be started, with a push, down the slope above the campfire.

And all about were the deeply sunken pug marks of the Cytha!
