There was no need for explanation, for both knew that they must pull for their lives. Kneeling, therefore, in the bottom of the boat, they each grasped a paddle with both hands and thrust the blade deep into the river. Then the surface swirled behind them, the craft gathered way, and ere a minute had passed they were shooting along beneath the overhanging branches.

"Keep where we are," gasped Tyler as he laboured at his paddle. "It is pitch dark in here, while outside the sharp eyes of the natives would pick us out. Keep a good look-out, and be ready to push her off in case we run into the bank."

That the latter was a likely occurrence was to be expected, for beneath the leafy avenue even in brilliant daylight all was sombre and clouded with gloom, while now that darkness had fallen and the sun had disappeared the tunnel under the trees presented not a ray, and indeed was buried in such obscurity that the two fugitives felt as though hemmed in by it, as though they could actually feel the darkness which surrounded them. But what could they do? Emerge into the open, so as to escape the risk of plunging into the trunk of a tree or running aground? That would be madness, for, as Tyler had observed, the night outside was not so black that the eyes of the Malays and sea Dyaks would fail to pierce it. And once they caught even the faintest glimpse of the flying boat, a suspicion even that it was paddling in that direction would bring them howling after it, and then the fate of the two Chinamen would be sealed. Yes, in an instant Tyler realized their precarious position; and though for the moment he considered whether it would not be better to halt where they were and lie still beneath the trees, he dismissed the idea next second, feeling that were they to do so the pirates would soon surround the spot, and, confident that they had cut off escape, would remain patiently till morning came and allowed them to surge down upon their daring enemies. Forward, therefore, and at all speed, was the order, and, reckless of the consequences, they plunged their paddles still deeper into the water till the bows of the tiny river-boat hissed against the stream, and sent the foam scudding on either side.

Hark! A shout, louder and more piercing than any which had preceded it, suddenly burst from the forest behind them, while the babel of voices came to an abrupt end. Then the cry was repeated, and ere a second had passed an answering hail came from up and down the river. Almost at the same moment the prow of the river-boat dashed into a pile of drift-wood, and, running forward till half her length was piled upon it, came to a halt, stranded there beneath the tunnel of trees.

"Hop out and float her again," whispered Tyler calmly. "Now stand still and listen. You heard the hail? Then did you catch those which answered it?"

"Yes, massa. A shout came from up de river, and anoder from down below. We am caught. We am prisoner at last, and when de day comee again poor Li and him massa die. Dey lose de head, and when de men comee from Sarawak and kill de pirate dey find dem slung to de back of de Dyaks."

Many a time, no doubt, had the humble Chinee seen men of the race which inhabited Borneo setting out upon an expedition to levy war upon their neighbours, and time and again had he observed the fact that all, or nearly all, of the warriors carried the heads of former victims slung to their girdles, for that was their custom. No wonder, therefore, as the prospect of imprisonment conjured up the scene and brought it afresh to his memory, that he shivered there, and, seeing that the end seemed so near, thought only of the worst. But Tyler also had heard of the custom, and indeed had even seen it with his own eyes. However, he was not the lad to be so easily frightened, and moreover he recognized the fact that life was sweet, and that to retain it now all his thoughts must be directed to escape, and not to the consequences of capture.

"Silence!" he exclaimed in low but commanding tones, the firmness of which caused the Chinaman to suddenly cease his whining. "We are not caught yet, and even if we are, what will it matter to either of us if our heads are taken and carried about, for we shall be dead? Don't be foolish, for, as I have said, we are not taken yet. There is a saying amongst my people which runs: 'First catch your bird, then cook him'. Let the pirates lay hands on us, then, and it will be time to moan about our fate. For the present it is our work to get away from them, and for my part I mean to escape whatever the difficulties. Now, get hold of the bows and lift. That's the way. Turn to the left and scramble into the jungle."

Abashed by the lecture which he had received, and encouraged by the bravery and calmness shown by his leader, Li Sung obediently carried out the order, and, lifting the head of the boat, carried it towards the bank. Tyler picked up the stern, and together they bore their craft into the jungle close at hand, and deposited it silently there.

"They shall have their patience tried," he said, as he threw himself upon the ground. "No doubt that shout warned men who were watching up and down the river, and now that they have been put on their guard the others will embark and will scour every foot of the water. If we had stayed on the drift-wood we should have been discovered, for they will search with torches to help them. Now we are hidden again, and can wait till the noise and the keenness of the hunt have died down."
