A hint of explanation came on the second morning of their ' visit, when Connolly accidentally lost himself in the forest.
After breakfast Connolly sat under the awning on the deck of the patrol launch, gazing out over the brown, jelly-like surface of the river. The campong was silent; During the night the Indians had disappeared into the bush. Like lemmings they were apparently prone to these sudden irresistible urges. Occasionally the nomadic call would be strong enough to carry them 2oo miles away; at other times they would set off in high spirits and then lose interest after a few miles, returning dispiritedly to the carpong in small groups. Deciding to make the most of their absence, Connolly shouldered the monitoring equipment and climbed on to the pier. A few dying fires smoked plaintively among the huts, and abandoned utensils and smashed pottery lay about in the red dust. In the distance the morning haze over the forest had lifted, and Connolly could see what appeared to be a low hill a shallow rise no more than a hundred feet in height-which rose off the flat floor of the jungle a quarter of a mile away. On his right, among the huts, someone moved. An old man sat alone among the refuse of pottery shards and raffia baskets, cross-legged under a small make-shift awning. Barely distinguishable from the dust, his moribund figure seemed to contain the whole futility of the Amazon forest. Still musing on Ryker's motives for isolating himself in the jungle, Connolly made his way towards the distant rise.
Ryker's behaviour the previous evening had been curious.
Shortly after dusk, when the sunset sank into the western forest, bathing the jungle in an immense ultramarine and golden light, the day-long chatter and movement of the Indians ceased abruptly. Connolly had been glad of the silence - the endless thwacks of the rattan canes and grating of the stone mills in wMeh they mixed the Government-issue meal had become tiresome. Pereira made several cautious visits to the edge of the campong, and each time reported that the Indians were sitting in a huge circle outside their huts, watching Ryker's bungalow. The latter was lounging on his veranda in the moonlight, chin in hand, one boot up on the rail, morosely surveying the assembled tribe.
'They've got their spears and ceremonial feathers,' Pereira whispered. 'For a moment I almost believed they were preparing an attack.'
After waiting half an hour, Connolly climbed up on to the pier, found the Indians squatting in their dark silent circle, Ryker glaring down at them. Only the witch-doctor's son made any attempt to approach Connolly, sidling tentatively through the shadows, a piece of what appeared to be blue obsidian in his hand, some talisman of his father's that had lost its potency.
Uneasily, Connolly returned to the launch. Shorfiy after three a.m. they were wakened in their bunks by a tremendous whoop, reached the deck to hear the stampede of feet through the dust, the hissing of overturned fires and cooking pots. Apparently leading the pack; Ryker, emitting a series of re-echoed 'Harooh's!' disappeared into the bush. Within a minute the campong was empty.
'What game is Ryker playing?' Pereira muttered as they stood on the creaking jetty in the dusty moonlight. 'This must be the focus of his authority over the Nambas.' Baffled, they went back to their bunks.
Reaching the margins of the rise, Connolly strolled through a small orchard which had returned to nature, hearing in his mind the exultant roar of Ryker's voice as it had cleaved the midnight jungle. Idly he picked a few of the barely ripe guavas and vividiy coloured cajus with their astringent delicately flavoured juice. After spitting away the pith, he searched for a way out of the orchard, but within a few minutes realized that he was lost.
A continuous mound when seen from the distance, the rise was in fact a nexus of small hillocks that formed the residue of a one-time system of ox-bow lakes, and the basins between the slopes were still treacherous with deep mire.
Connolly rested his equipment at the foot of a tree. Withdrawing his pistol, he fired two shots into the air in the hope of attracting Ryker and Pereira. He sat down to await his rescue, taking the opportunity to unlatch his monitors and wipe the dials.
After ten minutes no one had appeared. Feeling slightly demoralized, and frightened that the Indians might return and find him, Connolly shouldered his equipment and set off towards the north-west, in the approximate direction of the campong. The ground rose before him. Suddenly, as he turned behind a palisade of wild magnolia trees, he stepped into an open clearing on the crest of the hill.
Squatting on their heels against the tree-trunks and among the tall grass was what seemed to be the entire tribe of the Nambikwaras. They were facing him, their expressions immobile and watchful, eyes like white beads among the sheaves. Presumably they had been sitting in the clearing, only fifty yards away, when he fired his shots, and Connolly had the uncanny feeling that they had been waiting for him to make his entrance exactly at the point he had chosen.
Hesitating, Connolly tightened his grip on the radio monitor.
The Indians' faces were like burnished teak, their shoulders painted with a delicate mosaic of earth colours.
Noticing the spears held among the grass, Connolly started to walk on across the clearing towards a breach in the palisade of trees.
For a dozen steps the Indians remained motionless. Then, with a chorus of yells, they leapt forward from the grass and surrounded Connolly in a jabbering pack. None of them were more than five feet tall, but their plump agile bodies buffeted him about, almost knocking him off his feet.
Eventually the tumult steadied itself and two or three of the leaders stepped from the cordon and began to scrutinize Connolly more closely, pinching and fingering him with curious positional movements of the thumb and forefinger, like connoisseurs examining some interesting taxidermic object.
Finally, with a series of high-pitched whines and grunts, the Indians moved off towards the centre of the clearing, propelling Connolly in front of them with sharp slaps on his legs and shoulders, like drovers goading on a large pig. They were all jabbering furiously to each other, some hacking at the grass with their machetes, gathering bundles of leaves in their arms.
Tripping over something in the grass, Connolly stumbled onto his knees. The catch slipped from the lid of the monitor, and as he stood up, fumbling with the heavy cabinet, the revolver slipped from his holster and was lost under his feet in the rush.
Giving way to his panic, he began to shout over the bobbing heads around him, to his surprise heard one of the Indians beside him bellow to the others. Instantly, as the refrain was taken up, the crowd stopped and re-formed its cordon around him. Gasping, Connolly steadied himself, and started to search the trampled grass for his revolver, when he realized that the Indians were now staring, not at himself, but at the exposed counters of the monitor. The six meters were swinging wildly after the stampede across the clearing, and the Indians craned forward, their machetes and spears lowered, gaping at the bobbing needles.
Then there was a roar from the edge of the clearing, and a huge wild-faced man in a straw hat, a shotgun held like a crowbar in his hands, stormed in among the Indians, driving them back. Dragging the monitor from his neck, Connolly felt the steadying hand of Captain Pereira take his elbow.
