saying a word, he turned and walked away. The man who had spoken to him followed him threateningly for some little distance, as though to see that he had gone away as he was bidden to do. But presently he stopped, and Tom hurried on alone, until the boat and the crew and all were dropped away behind and lost in the moonlight night. Then he himself stopped also, turned, and looked back whence he had come.
There had been something very strange in the appearance of the men he had just seen, something very mysterious in their actions, and he wondered what it all meant, and what they were going to do. He stood for a little while thus looking and listening. He could see nothing, and could hear only the sound of distant talking. What were they doing on the lonely shore thus at night? Then, following a sudden impulse, he turned and cut off across the sand-hummocks, skirting around inland, but keeping pretty close to the shore, his object being to spy upon them, and to watch what they were about from the back of the low sand-hills that fronted the beach.
He had gone along some distance in his circuitous return when he became aware of the sound of voices that seemed to be drawing closer to him as he came towards the speakers. He stopped and stood listening, and instantly, as he stopped, the voices stopped also. He crouched there silently in the bright, glimmering moonlight, surrounded by the silent stretches of sand, and the stillness seemed to press upon him like a heavy hand. Then suddenly the sound of a man's voice began again, and as Tom listened he could hear some one slowly counting. "Ninety-one," the voice began, "ninety-two, ninety-three, ninety-four, ninety-five, ninety-six, ninety-seven, ninety-eight, ninety-nine, one hundred, one hundred and one" – the slow, monotonous count coming nearer and nearer to him – "one hundred and two, one hundred and three, one hundred and four," and so on in its monotonous reckoning.
Suddenly he saw three heads appear above the sand-hill, so close to him that he crouched down quickly with a keen thrill, close beside the hummock near which he stood. His first fear was that they might have seen him in the moonlight; but they had not, and his heart rose again as the counting voice went steadily on. "One hundred and twenty," it was saying – "and twenty-one, and twenty-two, and twenty-three, and twenty-four," and then he who was counting came out from behind the little sandy rise into the white and open level of shimmering brightness.
It was the man with the cane whom Tom had seen some time before – the captain of the party who had landed. He carried his cane under his arm now, and was holding his lantern close to something that he held in his hand, and upon which he looked narrowly as he walked with a slow and measured tread in a perfectly straight line across the sand, counting each step as he took it. "And twenty-five, and twenty-six, and twenty-seven, and twenty-eight, and twenty-nine, and thirty."
Behind him walked two other figures; one was the half-naked negro, the other the man with the plaited queue and the ear-rings, whom Tom had seen lifting the chest out of the boat. Now they were carrying the heavy box between them, laboring through the sand with shuffling tread as they bore it onward.
As he who was counting pronounced the word "thirty," the two men set the chest down on the sand with a grunt, the white man panting and blowing and wiping his sleeve across his forehead. And immediately he who counted took out a slip of paper and marked something down upon it. They stood there for a long time, during which Tom lay behind the sand-hummock watching them, and for a while the silence was uninterrupted. In the perfect stillness Tom could hear the washing of the little waves beating upon the distant beach, and once the far-away sound of a laugh from one of those who stood by the ship's boat.
One, two, three minutes passed, and then the men picked up the chest and started on again; and then again the other man began his counting. "Thirty and one, and thirty and two, and thirty and three, and thirty and four" – he walked straight across the level open, still looking intently at that which he held in his hand – "and thirty and five, and thirty and six, and thirty and seven," and so on, until the three figures disappeared in the little hollow between the two sand-hills on the opposite side of the open, and still Tom could hear the sound of the counting voice in the distance.
Just as they disappeared behind the hill there was a sudden faint flash of light; and by-and-by, as Tom lay still listening to the counting, he heard, after a long interval, a far-away muffled rumble of distant thunder. He waited for a while, and then arose and stepped to the top of the sand-hummock behind which he had been lying. He looked all about him, but there was no one else to be seen. Then he stepped down from the hummock and followed in the direction which the pirate captain and the two men carrying the chest had gone. He crept along cautiously, stopping now and then to make sure that he still heard the counting voice, and when it ceased he lay down upon the sand and waited until it began again.
Presently, so following the pirates, he saw the three figures again in the distance, and, skirting around back of a hill of sand covered with coarse sedge-grass, he came to where he overlooked a little open level space gleaming white in the moonlight.
The three had been crossing the level of sand, and were now not more than twenty-five paces from him. They had again set down the chest, upon which the white man with the long queue and the gold ear-rings had seated to rest himself, the negro standing close beside him. The moon shone as bright as day and full upon his face. It was looking directly at Tom Chist, every line as keen cut with white lights and black shadows as though it had been carved in ivory and jet. He sat perfectly motionless, and Tom drew back with a start, almost thinking he had been discovered. He lay silent, his heart beating heavily in his throat; but there was no alarm, and presently he heard the counting begin again, and when he looked once more he saw they were going away straight across the little open. A soft, sliding hillock of sand lay directly in front of them. They did not turn aside, but went straight over it, the leader helping himself up the sandy slope with his cane, still counting and still keeping his eyes fixed upon that which he held in his hand. Then they disappeared again behind the white crest on the other side.
So Tom followed them cautiously until they had gone almost half a mile inland. When next he saw them clearly it was from a little sandy rise which looked down like the crest of a bowl upon the floor of sand below. Upon this smooth, white floor the moon beat with almost dazzling brightness.
The white man who had helped to carry the chest was now kneeling, busied at some work, though what it was Tom at first could not see. He was whittling the point of a stick into a long wooden peg, and when, by-and-by, he had finished what he was about, he arose and stepped to where he who seemed to be the captain had stuck his cane upright into the ground as though to mark some particular spot. He drew the cane out of the sand, thrusting the stick down in its stead. Then he drove the long peg down with a wooden mallet which the negro handed to him. The sharp rapping of the mallet upon the top of the peg sounded loud in the perfect stillness, and Tom lay watching and wondering what it all meant.
The man, with quick-repeated blows, drove the peg farther and farther down into the sand until it showed only two or three inches above the surface. As he finished his work there was another faint flash of light, and by-and-by another smothered rumble of thunder, and Tom as he looked out towards the westward, saw the silver rim of the round and sharply outlined thundercloud rising slowly up into the sky and pushing the other and broken drifting clouds before it.
The two white men were now stooping over the peg, the negro man watching them. Then presently the man with the cane started straight away from the peg, carrying the end of a measuring-line with him, the other end of which the man with the plaited queue held against the top of the peg. When the pirate captain had reached the end of the measuring-line he marked a cross upon the sand, and then again they measured out another stretch of space.
So they measured a distance five times over, and then, from where Tom lay, he could see the man with the queue drive another peg just at the foot of a sloping rise of sand that swept up beyond into a tall white dune marked sharp and clear against the night sky behind. As soon as the man with the plaited queue had driven the second peg into the ground they began measuring again, and so, still measuring, disappeared in another direction which took them in behind the sand-dune, where Tom no longer could see what they were doing.
The negro still sat by the chest where the two had left him, and so bright was the moonlight that from where he lay Tom could see the glint of it twinkling in the whites of his eyeballs.
Presently from behind the hill there came,
