The sunshine was as quiet as before, but the blue Gulf Stream showed a darkening far away on the horizon, where a breeze ruffled the surface. He turned and gazed over the sea toward Florida, and a tiny black speck showed upon the waters of the reef. It looked like a small boat coming out through the Hawk's Channel, and he looked at it steadily for a long time, trying to see if it might be Haskins, the assistant keeper, returning.
The sunshine was very hot on this side of the tower, and it dazzled him for a little while as he gazed over the sparkling sea. The speck drew nearer, and he saw that it was a boat. It came very slowly, sailing with the light air, the bit of white canvas looking no larger than a handkerchief in the distance. Soon the figure of a man could be seen lying easily in the stern-sheets of the craft, and the old keeper saw that the man's legs were bare and brown. Then the tiny shallop took more definite form and showed to be a canoe, its occupant an Indian from the Everglades, coming out to fish upon the reef.
Indians seldom came so far away from land, and as the craft drew nearer and nearer Enau watched it carefully. The Seminoles were friendly. They were an unconquered tribe of Indians who had managed to evade all efforts made by the United States to subdue them. They had retired into the fastnesses of the great swamps, where no white soldier could pursue with any hope to capture, and after years of peace had come to the coast again with the understanding that they should not be molested. The old man had heard of them from Haskins, the assistant, and he had once or twice seen canoes skirting the edge of the great bay in the distance, but he had never seen an Indian close enough to recognize him. The canoe had now come within half a mile of the tower, and was still heading straight for it.
The breeze died away again and the sun shone straight down with an intense heat. The tower cast no shadow either to east or west, and the ship's clock in the kitchen struck off eight bells. Enau mopped his streaming forehead and was about to turn into the galley to get a drink of water. The heat made him reel with dizziness, but the man in the boat made a movement, and he held his gaze fixed upon him. The canoe was coming close to the tower, and it was evident that the Indian would land there if the keeper allowed him. There was no way of getting up to the light except by way of the long iron ladder which reached from the gallery to the sea, a hundred feet below. It was an easy path to dispute with any number of men, especially as they must come through the heavy trap-door in the gallery at the top. There was no way of getting up over the outside, unless one could climb the long, smooth iron rods for a great distance and then reach out under the sill to get a hand-grip upon the edge of the floor and swing out over the gulf below. It would be a mere finger-grip at most, and a tap upon the bare knuckles would send the fellow to his death below. A good sailor might climb the smooth iron rods with great difficulty, but no one could climb up a hundred feet and swing out on that finger-tip hold with the hope of climbing to the rail above. The trap-door worked with a five-hundred pound weight, and if any one tried to come up the thin iron ladder the keeper could simply lower the door and the stout three-inch planks would drop easily into place at will. Enau studied it all out while he gazed below, and it amused him to think what a surprised Indian it would be when he climbed up there to find the door drop fast in his face. No; the keeper was as much his own master in regard to human visitors as though he were a resident of some other planet. A thousand men could not approach him if he did not wish it. He could be all alone for an indefinite time, for he had provisions for half a year and water enough for a lifetime.
While he gazed at the approaching boat the man in her looked up. It was but a glance, a mere look at the head upon the rail above. Enau gasped. That one glance upward was enough for him. The fellow was not an Indian, after all. The sun-tanned face, burned to a dark mahogany colour, belonged to one he had not forgotten. That glance, furtive, half-shrinking, animal-like, without the movement of a single feature, belonged to—yes, there was no mistake. It was Robledo, the sailor who had witnessed against him, the survivor of the horror, the man who had compassed his ruin.
Enau drew his breath quickly and stood up straight. The place seemed to swing about in the sunshine, the tower to rock like a ship in a seaway. Then he peered over again just as the craft came alongside one of the iron pillars. He did not show his face,—just his eyes,—for fear the fellow might recognize him and not come up the ladder. He would have the trap-door ready for him, for it would never do to let that human devil know he was upon the light. Yes; perhaps he would let him come up, inside the gallery, but never go back. The sea would tell no tales. There would be no marks of a struggle, no evidence of a fight—a quick crack upon the head, and over the side, down a hundred feet to the waters of the reef, where the sharks lay waiting. That would be all. He could do it easily. But, then, the fellow might be missed, after all. Some one might know he had gone out to the light, and then there would be the investigation. That was what he did not want. There must be no inquiries, no questions asked him about his past. He was an old man now, and the memory of his terrible wrongs was fading. Let them die out. He would let the enemy go as he came. The fellow could not know he was in the tower, and there was no possibility of his recognizing him, as he had not shown his whole face over the rail. Even if he had, the hair and the beard of three years' growth would hide anything of Captain William Jacobs that still existed in him. No; he would let no one come up that ladder. He would live the rest of his life in peace and quiet. He loved the bright sunshine and the beautiful sea, and he could be satisfied where he was. His wife and daughter he had long given up. They had bade him farewell at the end of that trial, holding away from him, yet with tears streaming down their faces in the agony and horror of it all. He must be alone. There must be no one to tell him about them.
He looked down again, and saw the man below drawing on his trousers preparatory to climbing the ladder. Enau could see into the bottom of the boat beneath, and he noticed a harpoon used for spearing crawfish. Would the fellow take it with him? If so, it would be well not to let him come too near, for it could be thrown and might be dangerous. The man gave no hail, but turned his smooth-shaved face upward and began to mount the ladder, Enau went to the trap-door and loosed the weight softly. It creaked upon its hinges and settled slowly down until only a crack remained. Here he stopped it, with the bolts in readiness to shoot if necessary. He would watch the fellow and see if he showed signs of recognition. Ten years was a long time; the end of the Florida Reef was many thousand miles from where he had last seen him.
The man climbed slowly up the iron ladder, stopping now and then to look seaward. The current had swept his canoe to the northward of the lighthouse, where it trailed at the end of a long line. There was now nothing under him but the blue water. When he reached the first platform he climbed on to it and rested. It was very hot, and the climb made his mahogany-coloured face darker than before. His hair was freshly parted, and looked as though it had been oiled or moistened. His coat he had left in his boat below, and his shirt was open at the neck, showing the strong, corded muscles of his throat and chest. His hands were brown and powerful, and the keeper noticed how his fingers closed with a light but certain grip upon the irons of the ladder.
In a moment he came on again, and when within a few feet of the door he looked upward and hailed. At that instant the old man closed the door and shot the bolts. He was now cut off as completely as though he had gone to the moon. The heat and excitement made his head whirl. He staggered away from the closed door and went back to the gallery. The sunshine danced upon the sea and all was quiet. Then he peered over the rail. A string of muttered curses floated up to him and a drunken voice called him many foul names, but he only smiled and stood gazing out to sea. He could not see the man below now, for the fellow was too high up under the platform, and he made his way to the kitchen and from there higher up into the lantern, where the man's voice could not be heard distinctly.
Hours passed, and the sunshine began to slant sharply. The tower cast a long shadow to the eastward, but the canoe was still swinging to her painter, and the voice of the fellow below was still heard calling forth curses upon him. The keeper was evidently not recognized, for he heard the name "Enau" repeated over and over again, and this was his name as light-keeper—Robert Enau, head keeper of the Fowey Rocks lighthouse. If the fellow had recognized him he would have called him Jacobs, and then he would have tried to kill him. It grew dark, but he forgot to light his lantern, his whole mind taken with the one thought of how to get rid of his visitor. If the lantern was not lighted, the fellow might think that there was no one in the tower, after all, and would go away. The idea flashed through his brain for an instant, and then he centred his thoughts again on the fellow below and forgot the darkness and quiet of the tropic night. Suddenly he thought of the fellow's boat. If he could endanger it, the man might leave. He seized a heavy piece of iron and dropped it at the dark shadow floating at the end of the line. A dull crash told of the accuracy of his aim. Then the shadow faded out, and he knew the boat had sunk. There was no sound from the man upon the ladder below. Evidently he had gone down to the first landing and gone to sleep or was waiting, not knowing the damage done his craft. He could now neither go away nor come up, and the idea worried the keeper greatly. He was very dizzy with the heat and excitement, and his thoughts went again and again over the scenes of that last voyage and the trial following. In the gray of the early morning he was still sitting in the lantern, gazing out to sea, waiting for the sun to rise and show him his enemy below. The day dawned beautiful and clear, and the quiet heat continued. In a little while a noise upon the ladder attracted the old man's attention. He listened. What was the fellow saying?
