'Pull straight ahead,' said a voice, which seemed almost in his ear. He turned his face, and his heart leapt in his side. The muffled rowlocks and sweeps had brought the boat almost full upon him in silence, and the ruffian who sought his life was springing into the bows armed with the boat-hook. The boy scout saw all this clearly in the moonlight--saw the second man pulling with a terrified face turned over his shoulder, saw the heavy, iron-shod pole swinging aloft to fall upon his head. He drew a long breath, and filled his lungs deeply. As he did so, the shadow of the bow fell upon him, and at that instant he dived like a water-hen. There was a tremendous splash just at his ear, and a heavy blow was dealt on his shoulder, driving him deeper still. He turned over on his back, and opened his eyes, for he had closed them at the instant of diving. He saw directly above him a dark mass, and knew that he was under the boat. It passed slowly on, and he rose, and his face came to the surface and was brushed by a rope. He seized the rope and hung on, and drew, cautiously, a deep breath. He looked round, and found that he had caught the painter as it dragged astern, and that the way of the boat was checked. Then Chippy heard a voice. 'Pull round a bit,' it asid; 'we shall soon see if he rises again or no.' 'Not he,' said another voice, which quavered. 'Never! never! He'll ne'er rise again after that frightful crack you hit him. I shall hear it all my days.' The hardier ruffian chuckled. 'I did fetch him a good un,' he said--'a reg'lar oner. I felt the hook light on him. But pull, I tell ye--pull! There's no time for moanin' an' groanin' now.' Chippy felt that way was being given to the boat, and he struck out softly with one arm and both feet in order that he should not drag on the boat and betray his presence. By the aid of the painter, he could keep his head low behind the broad stern, and quite out of sight of the two rogues in the boat. His shoulder ached where the boat-hook had fallen upon it, but the blow had not been disabling, for the force had been partly broken by the water. In one way, it was very lucky for the scout that he had received this sharp crack, for the thief who sought his life was now fully under the impression that the boy had been beaten under. This caused the two rogues to be less thorough in their search for a head showing above the water. The boat was gently paddled round the spot where Chippy had disappeared, but the men did not move to and fro in the boat, glancing on every side. Had they done so, the head bobbing along under the stern would have been discovered, and there would have been a short shrift for the daring scout. 'He'll never come up--never,' said the rower, his voice still unsteady; 'you stunned him, an' I've heard as anyone stunned will never rise again.'
