At the long-house at which Barunda and Ninaka had halted, Muda Saffir learned all that had transpired, his informants being the two Dyaks who had led Bulan and his pack into the jungle. He imparted the information to von Horn and both men were delighted that thus their most formidable enemy had been disposed of. It would be but a question of time before the inexperienced creatures perished in the dense forest—that they ever could retrace their steps to the river was most unlikely, and the chances were that one by one they would be dispatched by head hunters while they slept.

Again the party embarked, reinforced by the two Dyaks who were only too glad to renew their allegiance to Muda Saffir while he was backed by the guns of the white men. On and on they paddled up the river, gleaning from the dwellers in the various long-houses information of the passing of the two prahus with Barunda, Ninaka, and the white girl.

Professor Maxon was impatient to hear every detail that von Horn obtained from Muda Saffir and the various Dyaks that were interviewed at the first long-house and along the stretch of river they covered. The doctor told him that Number Thirteen still had Virginia and was fleeing up the river in a swift prahu. He enlarged upon the valor shown by Muda Saffir and his men in their noble attempt to rescue his daughter, and through it all Sing Lee sat with half closed eyes, apparently oblivious to all that passed before him. What were the workings of that intricate celestial brain none can say.

Far in the interior of the jungle Bulan and his five monsters stumbled on in an effort to find the river. Had they known it they were moving parallel with the stream, but a few miles from it. At times it wound in wide detours close to the path of the lost creatures, and again it circled far away from them.

As they travelled they subsisted upon the fruits with which they had become familiar upon the island of their creation. They suffered greatly for lack of water, but finally stumbled upon a small stream at which they filled their parched stomachs. Here it occurred to Bulan that it would be wise to follow the little river, since they could be no more completely lost than they now were no matter where it should lead them, and it would at least insure them plenty of fresh water.

As they proceeded down the bank of the stream it grew in size until presently it became a fair sized river, and Bulan had hopes that it might indeed prove the stream that they had ascended from the ocean and that soon he would meet with the prahus and possibly find Virginia Maxon herself. The strenuous march of the six through the jungle had torn their light cotton garments into shreds so that they were all practically naked, while their bodies were scratched and bleeding from countless wounds inflicted by sharp thorns and tangled brambles through which they had forced their way.

Bulan still carried his heavy bull whip while his five companions were armed with the parangs they had taken from the Dyaks they had overpowered upon the island at the mouth of the river. It was upon this strange and remarkable company that the sharp eyes of a score of river Dyaks peered through the foliage. The head hunters had been engaged in collecting camphor crystals when their quick ears caught the noisy passage of the six while yet at a considerable distance, and with ready parangs the savages crept stealthily toward the sound of the advancing party.

At first they were terror stricken at the hideous visages of five of the creatures they beheld, but when they saw how few their numbers, and how poorly armed they were, as well as the awkwardness with which they carried their parangs, denoting their unfamiliarity with the weapons, they took heart and prepared to ambush them.

What prizes those terrible heads would be when properly dried and decorated! The savages fairly trembled in anticipation of the commotion they would cause in the precincts of their long-house when they returned with six such magnificent trophies.

Their victims came blundering on through the dense jungle to where the twenty sleek brown warriors lay in wait for them. Bulan was in the lead, and close behind him in single file lumbered his awkward crew. Suddenly there was a chorus of savage cries close beside him and simultaneously he found himself in the midst of twenty cutting, slashing parangs.
