It was quite a formidable expedition that departed from Berande at break of day next morning in a fleet of canoes and dinghies. There were Joan and Sheldon, with Binu Charley and Lalaperu, the eight Tahitians, and the ten Poonga-Poonga men, each proud in the possession of a bright and shining modern rifle. In addition, there were two of the plantation boat's-crews of six men each. These, however, were to go no farther than Carli, where water transportation ceased and where they were to wait with the boats. Boucher remained behind in charge of Berande.

By eleven in the morning the expedition arrived at Binu, a cluster of twenty houses on the river bank. And from here thirty odd Binu men accompanied them, armed with spears and arrows, chattering and grimacing with delight at the warlike array. The long quiet stretches of river gave way to swifter water, and progress was slower and more dogged. The Balesuna grew shallow as well, and oftener were the loaded boats bumped along and half-lifted over the bottom. In places timber-falls blocked the passage of the narrow stream, and the boats and canoes were portaged around. Night brought them to Carli, and they had the satisfaction of knowing that they had accomplished in one day what had required two days for Tudor's expedition.

Here at Carli, next morning, half-way through the grass-lands, the boat's-crews were left, and with them the horde of Binu men, the boldest of which held on for a bare mile and then ran scampering back. Binu Charley, however, was at the fore, and led the way onward into the rolling foot-hills, following the trail made by Tudor and his men weeks before. That night they camped well into the hills and deep in the tropic jungle. The third day found them on the run-ways of the bushmen--narrow paths that compelled single file and that turned and twisted with endless convolutions through the dense undergrowth. For the most part it was a silent forest, lush and dank, where only occasionally a wood-pigeon cooed or snowwhite cockatoos laughed harshly in laborious flight.

Here, in the mid-morning, the first casualty occurred. Binu Charley had dropped behind for a time, and Koogoo, the PoongaPoonga man who had boasted that he would eat the bushmen, was in the lead. Joan and Sheldon heard the twanging thrum and saw Koogoo throw out his arms, at the same time dropping his rifle, stumble forward, and sink down on his hands and knees. Between his naked shoulders, low down and to the left, appeared the bone-barbed head of an arrow. He had been shot through and through. Cocked rifles swept the bush with nervous apprehension. But there was no rustle, no movement; nothing but the humid oppressive silence.

"Bushmen he no stop," Binu Charley called out, the sound of his voice startling more than one of them. "Allee same damn funny business. That fella Koogoo no look 'm eye belong him. He no savvee little bit."

Koogoo's arms had crumpled under him, and he lay quivering where he had fallen. Even as Binu Charley came to the front the stricken black's breath passed from him, and with a final convulsive stir he lay still.

"Bight through the heart," Sheldon said, straightening up from the stooping examination. "It must have been a trap of some sort."

He noticed Joan's white, tense face, and the wide eyes with which she stared at the wreck of what had been a man the minute before.

"I recruited that boy myself," she said in a whisper. "He came down out of the bush at Poonga-Poonga and right on board the Martha and offered himself. And I was proud. He was my very first recruit--"

"My word! Look 'm that fella," Binu Charley interrupted, brushing aside the leafy wall of the run-way and exposing a bow so massive that no one bushman could have bent it.

The Binu man traced out the mechanics of the trap, and exposed the hidden fibre in the tangled undergrowth that at contact with Koogoo's foot had released the taut bow.

They were deep in the primeval forest. A dim twilight prevailed, for no random shaft of sunlight broke through the thick roof of leaves and creepers overhead. The Tahitians were plainly awed by the silence and gloom and mystery of the place and happening, but they showed themselves doggedly unafraid, and were for pushing on. The Poonga-Poonga men, on the contrary, were not awed. They were bushmen themselves, and they were used to this silent warfare, though the devices were different from those employed by them in their own bush. Most awed of all were Joan and Sheldon, but, being whites, they were not supposed to be subject to such commonplace emotions, and their task was to carry the situation off with careless bravado as befitted "big fella marsters" of the dominant breed.

Binu Charley took the lead as they pushed on, and trap after trap yielded its secret lurking-place to his keen scrutiny. The way was beset with a thousand annoyances, chiefest among which were thorns, cunningly concealed, that penetrated the bare feet of the invaders. Once, during the afternoon, Binu Charley barely missed being impaled in a staked pit that undermined the trail. There were times when all stood still and waited for half an hour or more while Binu Charley prospected suspicious parts of the trail. Sometimes he was compelled to leave the trail and creep and climb through the jungle so as to approach the man-traps from behind; and on one occasion, in spite of his precaution, a spring-bow was discharged, the flying arrow barely clipping the shoulder of one of the waiting Poonga-Poonga boys.

Where a slight run-way entered the main one, Sheldon paused and asked Binu Charley if he knew where it led.

"Plenty bush fella garden he stop along there short way little bit," was the answer. "All right you like 'm go look 'm along."

"'Walk 'm easy," he cautioned, a few minutes later. "Close up, that fella garden. S'pose some bush fella he stop, we catch 'm."

Creeping ahead and peering into the clearing for a moment, Binu Charley beckoned Sheldon to come on cautiously. Joan crouched beside him, and together they peeped out. The cleared space was fully half an acre in extent and carefully fenced against the wild pigs. Paw-paw and banana-trees were just ripening their fruit, while beneath grew sweet potatoes and yams. On one edge of the clearing was a small grass house, open-sided, a mere rain-shelter. In front of it, crouched on his hams before a fire, was a gaunt and bearded bushman. The fire seemed to smoke excessively, and in the thick of the smoke a round dark object hung suspended. The bushman seemed absorbed in contemplation of this object.

Warning them not to shoot unless the man was successfully escaping, Sheldon beckoned the Poonga-Poonga men forward. Joan smiled appreciatively to Sheldon. It was head-hunters against headhunters. The blacks trod noiselessly to their stations, which were arranged so that they could spring simultaneously into the open. Their faces were keen and serious, their eyes eloquent with the ecstasy of living that was upon them--for this was living, this game of life and death, and to them it was the only game a man should play, withal they played it in low and cowardly ways, killing from behind in the dim forest gloom and rarely coming out into the open.

Sheldon whispered the word, and the ten runners leaped forward--for Binu Charley ran with them. The bushman's ............
