"They cannot be avoided, no matter where we camp," said Fabrache. "Three men with firebrands can keep them at a distance, if such a need arises."

"Then we must keep watch during the night?"

"Not at all," replied Fabrache. "The pacers will watch, and I will keep the fire ablaze."

He tethered the pacers to a tree and built a fire on the shore. Then, while Ifness and Etzwane collected a stack of resinous yew branches, Fabrache snared a dozen mud crabs, which he cracked, cleaned, and toasted, and meanwhile cooked meal cakes on hot, flat stones. "You are highly efficient," said Ifness. "It is a pleasure to watch you at work."

Fabrache gave his head a dour shake. "I know nothing else but this; a skill acquired across a lifetime of hardship. I take no great pleasure from your compliment."

"Surely you have other skills?"

"Yes. I am reckoned a good barber. Occasionally in jest I imitate the mating antics of the ahulphs. But these are modest accomplishments; ten years after my death I will be forgotten, and one with the soil of Caraz. Still, I consider myself a fortunate man, more so than most. I have often wondered why it was given to me to live the life of Kyril Fabrache."

"These reflections, at one time or another, have occurred to all of us," said Ifness, "but unless we are agreed upon a religion of gradated reincarnation, the question is ingenuous. " He rose to his feet and surveyed the landscape. "I assume that the Red Devils never ranged this far west?"

Piqued by Ifness' indifference to his quest for personal truth, Fabrache gave only a short reply. "They never even reached Shagfe. " He went off to tend the pacers.

Ifness considered the mass of the Orgai to the north, where the crag Thrie Orgai flared purple in the last rays of the setting suns. 'In this case, the spaceship battle would seem isolated from the slaughter of the Roguskhoi," he mused. "The events are of course related; there can be no doubt of this much.… Tomorrow will be an interesting day. " He made one of his rare gesticulations. "If I can produce a spaceship, even a hulk, I am vindicated. Dasconetta will be gray with rage; even now he gnaws his knuckles by the hour… We can only hope that these spaceships exist in fact, that they are something more than mare's nests."

Etzwane, vaguely irked by the nature of Ifness' aspirations, said, "I can see no value to a wrecked spaceship; they have been known for thousands of years, and must be common throughout the system of Earth worlds."

"True," declared Ifness, still elevated by his visions of triumph, "but these are the product of human knowledge, and many knowledges exist."

"Bah," growled Etzwane. "Iron is iron, glass is glass, and this is the same here or at the end of the universe."

"True once more. The gross elementals are known to all. But there is no finite limit to knowledge. Each set of apparent ultimates is susceptible to examination and must be analyzed in new terms. These succeeding layers of knowledge are numberless. Those familiar to us are each derived from the level above, or below. Conceivably entire disassociated phases of knowledge exist; the field of parapsychology comes to mind. The basic law of the cosmos is this: in a situation of infinity, whatever is possible exists in fact. To particularize, the technology which propels an alien spaceship may be different from that of Earth, and such a technology must be a matter of intense interest, if only philosophically. " Ifness considered the fire. "I must remark that augmented knowledge is not necessarily a boon, and might easily be dangerous."

"In that case," Etzwane asked, "why are you so anxious to broadcast this knowledge?"

Ifness chuckled. "First, it is my normal human inclination to do so. Second, the group of which I am part- from which Dasconetta would naturally be expelled- is competent to control the most dangerous secrets. Thirdly, I cannot overlook my personal advantage. If I deliver an alien spaceship to the Historical Institute, even a wrecked hulk, I will gain great prestige."

Etzwane turned away to make up his bed, reflecting that of Ifness' three reasons, the last was probably the most cogent.

The night passed without incident. Three times Etzwane awoke. Once he heard from far off the rumbling -challenge of a chumpa and from an even greater distance the answering calls of an ahulph tribe, but none came to disturb the camp by the river.

Fabrache awoke before dawn. Blowing up the fire, he prepared a breakfast of porridge boiled with pepper meat and tea.

Not long after dawn the three mounted their pacers and set off to the south along the banks of the Vurush. Gradually they rose into the Orgai.

Shortly before noon Fabrache jerked his pacer to a halt. He cocked his head as if listening, and looked slowly to all sides.

"What is the matter? " asked Ifness.

Fabrache said nothing. He pointed ahead toward the gap into a stony valley. "Here is where the black globes discovered the disk ships; here is where the battle took place. " Rising to stand in his stirrups he searched the hillsides and reexamined the sky.

"You have a presentiment," said Etzwane softly.

Fabrache pulled nervously at his beard. "The valley has known a wonderful event; the air still tingles… Is there not something more? " Fretfully he swung his gaunt body around in the saddle, rolling his eyes from side to side. There is pressure upon me."

Etzwane scanned the valley. To right and left, harsh gullies cut into sandstone, the high areas baking white-violet in the sunlight, the deep shadows a black bottle-green. A flicker of motion caught his eye; not a hundred feet distant crouched a large ahulph, considering whether or not to hurl a stone. Etzwane said, "Perhaps you feel the gaze of yonder ahulph."

Fabrache swung about, annoyed that Etzwane had seen the creature first. The ahulph, a blue-black buck of a variety unknown to Etzwane, shook its ear fibers uneasily and started to move away. Fabrache called out in de-da pidgin. The ahulph paused. Fabrache spoke again, and with the swaggering waggishness typical of the higher ahulphs, it bounded down from the jut. Politely it released a waft of "gregariousness "

•The higher ahulphs control four odors, signifying gregariousness, hostility, and two varieties of excitement unknown to the and sidled forward. Fabrache dismounted from his pacer and signaled Etzwane and Ifness to do likewise. Tossing a chunk of cold grain cake to the ahulph, he spoke again in de-da. The ahulph made a fervent and elaborate response. _

Fabrache turned to Ifness and Etzwane. "The ahulph watched the battle. He has explained to me the sequence of events. Two copper disk-ships landed at the end of the valley and remained there almost a week. Persons came out to walk around. They stood on two feet, but exuded a nonhuman odor. The ahulph paid no attention to their appearance. They did nothing during their stay and came outside only at dawn and dusk. Three days ago, at noon, four black globes appeared a mile overhead. The disk-ships were taken by surprise. The black globes sent down lightning bolts and exploded both disk-ships, then departed as abruptly as they had come. The ahulphs watched the wrecks, but felt diffident about approaching. Yesterday a large disk-ship dropped from the sky. After hovering an hour, it lifted the hulk which had suffered the least damage and carried it away. Fragments of the second hulk remain."

"Interesting news," murmured Ifness. 'Toss the creature another morsel of grain cake. I am anxious to inspect the shattered hulk."

Fabrache scratched his chin where the first hairs of human race. The innumerable races of lower ahulphs vent only hostility and an attractive scent. The ahulph mentality at times seems to resemble human intelligence, but the similarity is misleading, and attempts to deal with ahulphs on a basis of human rationality end in frustration. The ahulph, for instance, cannot understand working for hire, no matter how carefully the matter is explained. his beard had their roots. "I must admit to a diffidence not unlike that of the ahulph. The valley holds an uncanny presence which I do not care to test."
