Billy took the tiller in silence. After a little while Gaff drew his son’s ear near to his mouth, and said in a low whisper—
“Billy, my lad, I must have a sleep, but I dursn’t do it unless you keep a sharp eye on the captain. He’s after mischief, I’m quite sure o’ that, so give me a tremendous dig in the ribs if he offers to rise from his seat. Mind what I say now, lad. Our lives may depend on it.”
Billy promised to be watchful, and in less than two minutes afterwards Gaff was sunk in deep repose.
The boy was faithful to his trust. Without appearing to be watching him, he never for one moment removed his eyes so far from where the captain sat labouring at the oars as to give him a chance of moving without being seen. As time passed by, however, Billy found it difficult to keep awake, and, in proportion as this difficulty increased, his staring at the captain became more direct and intense. Of course Graddy perceived this, and the sneering smile that crossed his visage showed that he had made a shrewd guess at the cause of the lad’s attentions.
By degrees Billy’s eyes began to droop, and he roused himself frequently with a strong effort, feeling desperately alarmed lest he should be overcome. But nature was not to be denied. Again and again did his head fall forward, again and again did he look up with a startled expression to perceive that Graddy was regarding him with a cold sardonic smile. Gradually Billy’s eyes refused to convey a correct impression of what they rested on. The rower’s head suddenly became twice as large as his body, a sight which so alarmed the boy that he started up and could scarce restrain a cry, but the head had shrunk into its ordinary proportions, and the sardonic smile was there as before.
Oh! what would not Billy have given at that time to have been thoroughly wide-awake and fresh! He thought for a moment of awaking his father, but the thought was only half formed ere sleep again weighed down his spirit, causing his eyelids to blink despite his utmost efforts to keep them open. Presently he saw Graddy draw the right oar quietly into the boat, without ceasing to row with the left one, and slowly draw the knife which hung at his belt.
The boy tried to shout and arouse his father, but he was paralysed with horror. His blood seemed to curdle in his veins. No sound would issue from his lips, neither could he move hand or foot while the cold glassy eye of the captain rested on him.
Suddenly Graddy sprang up, and Billy’s voice found vent in a shrill cry. At the same moment Stephen Gaff awoke, and instinctively his hand grasped the tiller. He had no time to rise, but with the same force that drew the tiller from its socket in the helm he brought it forward with crashing violence on the forehead of Graddy, who was stooping to plunge the knife into his breast. He staggered beneath the blow. Before he could recover himself it was repeated, and he fell heavily back into the bottom of the boat.
“Thank the Lord,” murmured Gaff, as he leaned over his fallen foe, “the villain’s hand has bin stopped short this time. Come, Billy, help me to lift him up.”
Gaff’s blows had been delivered with such vigour that Graddy’s head was much damaged, and it was a long time before the two could get him restored sufficiently to sit up. At length, however, he roused himself and looked with a bewildered air at the sun, which had just risen in a flood of golden light. Presently his eyes fell on Gaff, and a dark scowl covered his face, but being, or pretending to be unable to continue long in a sitting posture, he muttered that he would lie down and rest in the bow of the boat. He got up and staggered to the spot, where he lay down and soon fell fast asleep.
