But the work was not yet completed. Piang let go his anchorage and headed for the mouth of the ditch. The water was rapidly widening the work of their hands, but in places the cut-off was barely wide enough to let the long slender floats by, and the water was rushing through with terrific force. The moon trembled on the brink of the jungle. Would they reach the other side in time to aid Kali? Suppose he was driven back before Piang and his men could attack from the other side?

Ala! ala!” (“Quickly! quickly!”) Piang called softly. His raft came up with a sudden jerk, almost throwing him into the seething, muddy torrent. Other rafts bumped into his, and soon a blockade was forming as the swift current bore them down upon him. Piang cut and slashed at the banks, tearing away protruding vines and accumulating driftwood. The moon, the moon, would it wait? Frantically he toiled while Tooloowee held off the other rafts with his long pole. When Piang’s float was finally released, it bounded joyously along, nosing first one bank, then the other. The river! He could see it! Only a few rods more!

At the mouth of the ditch there was more trouble. Mud and debris had collected along the sides, but these were quickly worked through and they passed into the main river. Little short of a miracle had been performed. The ditch was growing wider and deeper every moment and judging from the enormous flow of water, it would not be long before the river deserted its circuitous route in favor of this direct one.

“Quick! quick!” whispered Piang. “Bungao, bind the siwaka rafts together and head for Cotabato. We will overtake you before sunrise.” A faint cry reached them. Kali had begun the attack. In an agony of suspense the brave Moros worked their way up toward the Big Bend. Suddenly Piang grasped Tooloowee’s arm and pointed toward a streak that ran across the river.

“The boom! We must cut it!” They made a dash toward the obstacle that stood in Kali’s path, but an arrow whizzed by their heads.

“Tooloowee, we have been discovered. I go to cut the way!” and before the astonished Tooloowee could prevent, Piang had dived into the water and disappeared.

“Piang, the crocodiles, the crocodiles!” wailed Tooloowee, but the charm boy could not hear as he slipped up the muddy river, swimming easily under water. Just as Kali was preparing to retreat, driven back by the fierce storm of arrows, he gave the signal that had been agreed upon. Three loud calls in imitation of the mina-bird went wailing through the night. What was Kali’s surprise to hear the answer a few yards in front of him! And what was that dark shape bobbing up and down on the boom?

While he watched, amazed, the big clumsy logs divided, and swung slowly out, leaving the channel clear. Piang had severed the ratan thongs.

“Lééééé lelele ouiiiiii!” crashed through the night, and Kali recognized his tribal war-cry.

“Piang! Piang!” he cried. The dark shape, clinging to the drifting boom answered, and Kali rushed toward it. Before the enemy could gather their scattered wits, the whole party was sweeping by, on toward freedom. As Kali bore down on Piang, the boy raised himself to meet the raft. It was coming at a terrific rate, and he feared it would knock him off the boom; measuring the distance, he prepared to leap. On came the raft, Kali leaning far over the side, arms extended to grab the boy. When Kali was only a few yards off, Piang screamed:
