At last Errington came out into the pool. He paddled quickly across it, in a direction away from the river, satisfying himself by a rapid glance around that no other boat was in sight. Just as he reached the farther side, the Chinamen’s boat shot out from among the reeds. They stopped paddling, looking round for their quarry, and catching sight of him near a reed-bed about three hundred yards away, they opened fire. The bullets passed unpleasantly close, and Errington at once drove the boat into one of the many narrow channels, and was out of sight in a few seconds. Thereupon the Chinamen gave chase again; but when they reached the other side of the pool, and saw that the enemy had disappeared, they apparently recognized that they were outmatched, and stopped to consider what they should do. At this moment a loud and prolonged coo-ee sounded from the midst of the swamp. Whether they recognized it as a signal or not, it roused them to desperate energy. Concealed by the reeds, Errington listened to a violent altercation among them. They were disputing which of them should enter the water and so lighten the boat. It ended in three of the six who had been marooned slipping over the side and wading slowly towards a small dry patch, where they posted themselves, holding their rifles ready to shoot at the fugitives if they should reappear. The remaining men drove their boat rather more rapidly than before in the direction from which the coo-ee had come. Errington had not seen what had been done, but hearing the boat approaching, he started again, paddling easily until the pursuers came into view. The fact that they had lightened the boat did not trouble him. His boat was of about the same size, and Lo San and he could easily keep ahead. But he was somewhat anxious lest he should presently find himself in a blind alley. He did not know the part of the swamp to which he had now come, and it was quite possible that, entering a passage that seemed free, he would come upon an impenetrable belt of reeds that would form an effectual barrier. If at such a moment the enemy were in sight, he might well be overhauled before he could get free. The pursuing boat, although no longer burdened with a double crew, was lower in the water than that in which Errington and Lo San were. It flashed upon Errington that if he could only find a channel where the depth of water was not more than sufficient to allow the passage of his boat, the other might stick in the mud and relieve him of further trouble. He remembered that, when circling the pool with Lo San, he had come to very shallow water at the end farthest from the river, and wondered whether he could find his way there now.
