The sea-devil gave the craft a tremendous push which sent it clear over, and then he slipped under it to find the game on the side beyond. The man was gone, but he saw him hanging to the buoy close by, and he gave a sudden dash to seize him. At that instant Riley clambered like a cat upon the swinging iron, and by almost superhuman balancing he sat up on the top, some four feet clear of the water, his legs swinging on either side, making frantic efforts to keep his unstable craft from turning around in the current and spilling him into the death-trap which now lurked below in plain view. He prayed for a whale iron, and screamed for help. Then he swore furiously and madly at the shape with the stony eyes which, as implacable as death itself, lay watching him as though certain of the ultimate outcome of the affair. Without even his knife he would not be able to make the least resistance. A harpoon iron would have fixed things differently. Oh, for one to throw at the hideous thing waiting for him! How he would like to see the barbs sink into that hard hide and pierce its vitals. He raved at it, and cursed it frantically, but the sea-devil lay there silently watching, knowing well that it was but a question of a few minutes before he would be at his mercy.

The hot afternoon sun beat pitilessly upon the clinging wretch upon the can buoy, and the heat upon his bare head made the water dance about him. But to lose his balance was fatal, and he clung and cried, prayed and screamed, cursed and raved, alternately, adjusting his trembling body to each movement of his float.

As the minutes flew by, Samuels, who was rowing to him with rapid strokes, heard his outcries, and turned to look. He could not understand the man’s wild terror. It was evident that there was no time to lose, and he bent to the oars again. Suddenly he heard a piercing scream. He turned, and in time to see a great shape rise from the water like a gigantic bat, and sail right for the top of the can buoy. It struck it fair, and the thud of the huge body resounded over the sea. Then it fell slanting off into the water with a great splash, and when he looked at the top of the can there was nothing but a piece of blue cloth hanging to the ring-bolt. Riley was gone.

In an instant Samuels sprang to his feet and stood looking at the eddying current, paralyzed with horror at the sight. The hot sunshine and smooth sea were still all around him, but the monstrous shape had disappeared and his companion along with it. Now he knew why Riley had screamed and cursed so frantically. It was not the fear of drowning that had called forth such madness. But even while he stood there in the sunlight a horrible nightmare seemed to be taking possession of him, and he was trembling and helpless. He gave a hoarse cry and set his teeth to control his shaking nerves. Then his brain began its normal working again, and he seized his oars and gave several tremendous strokes in the direction of the buoy, looking over his shoulder and feeling his scalp tightening upon his head. There was a cold chill in his blood, as though the weather were winter instead of torrid July.

Suddenly something showed on the surface just under the boat’s bow. He shivered in spite of himself, but the thought of his comrade nerved him for the ordeal. He sprang forward, knife in hand, to seize it if it were Riley’s form, or face the monster if he appeared. A white hand came slowly upward. With a desperate effort Samuels reached over and jerked the form of his assistant into the boat, and as he did so a huge shadow darkened the water beneath him.

The sea-devil, carried along by the momentum of his rush, had knocked his victim into the water from the buoy top, but had swept past him before he could swing about far enough to seize him in his jaws. This was all that saved Riley.

Instantly Samuels, who had a stout craft, seized his oars and pulled for the lighthouse, gazing fixedly upon the smooth water astern of him, and shivering with a nervous shake at each ripple in the wake of his boat, lest it were made by the denizen below the surface. But nothing followed. The Sound was as smooth as glass, and the sunshine and silence were undisturbed. The great ray had missed his victim, and was swimming slowly around the can buoy looking for him. He had failed to notice Samuels pick him up, although he had seen his boat pass.

While Samuels watched astern he saw the capsized craft near the buoy move suddenly, as though some power were exerted upon it from below. The sight caused him to bend with renewed vigor to his oars, and, with his heart sending his blood jerking through his temples with a pulse he seemed almost to hear, he drove his boat for the beach and landed safely. As he did so Riley sat up and looked about him with eyes that were like those of a man in a dream. His lips were swollen to a livid blue and he puffed through them, making a ghastly sound as they quivered with his breath. Samuels spoke to him, but he would only gaze about him and make the blowing noise with his mouth. Then the elder keeper took him gently by the arm and led him painfully up the sand to the lighthouse dwelling. The next day the victim was raving. It would take a long time for the poor fellow to regain his equilibrium, and absolute rest and quiet were the only thing that would steady the terribly shaken nerves. Samuels took the man to the nearest town, and then went back to tend the light alone.

The following week Samuels spent brooding over the horrible affair. The log of the keeper refers to it several times, and it was like a wild nightmare to him during his watch on the tower during darkness. During the daytime he thought of it continually, and began to devise different methods for the capture of the sea-devil, which he believed to be still in the entrance of the Sound. He had sent word of the unfortunate Riley’s condition to the inspector, and was tending the light alone when the new assistant came to relieve him. When he arrived he found Samuels hard at work upon a set of harpoons and lines which he had been preparing for his hunt, while a couple of large shark-hooks lay in the small boat ready baited. Two small boats were made ready, and the shark-hooks and lines were placed in one. The other contained five lilly-irons of the grummet-and-toggle pattern and two hundred fathoms of small line capable of holding the small boat while being towed at any speed. With this outfit they began to spend the days upon the waters of the Sound, rowing in company to the various fishing drops, and trying for a bite upon the great hooks.

Not a sign of the sea-devil had there been since the day the keeper had met him. The weather was clear and fine, and the sea smooth. Nothing rose to break the even surface. But Samuels hunted quietly on, never losing faith that some day the monster would break water again and give him a chance for either a harpoon or hook. In his boat he carried a long whale lance with its heart-shaped head as sharp as a razor, covered in a wooden scabbard to keep off the dampness. It would penetrate any living body a full fathom, and nothing of flesh and blood could withstand its stroke.
