I laughed, involuntarily, at this childishness. The old man frowned.

“There’s some things that perhaps even you all-fired clever young fellows don’t know,” he said, crushingly. “’Tain’t the first time I’ve heard of this sort of thing. A mate of mine in the old days at ’Frisco was waked up one morning by the ghost of a prospector who’d died up in the ranges. He told him just where he’d made his strike before his grub gave out. My mate had never heard of the place but he lit straight away on the trail—and sure enough the ghost was telling the truth. Old Jim Hamilton it was—and he drank himself to death on what he got out of it.” The old man looked me straight in the eyes as though challenging me to doubt him. Of course, I could say nothing. He grunted scornfully, and turned again to the chart still spread out upon the table. “It’s a nice quiet out-of-the-way place,” reflected the old ruffian, putting his thumb-nail on the lonely island. “Just the location for a cache—guess they’d feel pretty sure of not being interfered with there!” There was a grim undertone in his voice which was decidedly ugly. He might, himself, have been the reincarnation of just such a pirate as the one whose existence he was postulating.

Well, nothing more happened that night. Mrs. Vandermeulen, thoroughly alarmed and uneasy, hustled her daughter off to bed. Old Vandermeulen and his son sat up in an endless discussion of the mysterious script, referring again and again to the chart which so startlingly confirmed its indications, and speculating optimistically as to the nature and amount of the treasure they were convinced was buried in the designated place. They talked themselves into a complete faith in the supernatural origin of the message, and, father and son alike—it was curious to note the traits of resemblance which cropped out in them—were equally indifferent as to whether its source was diabolic or benevolent. Enormously wealthy although they already were, the prospect of this phantom gold waiting to be unearthed had completely fascinated them. At last I turned in, wearied with the thousand and one questions they asked me and to which I could give no answer, disgusted with their avarice, and scornfully contemptuous of their simplicity.

I found sleep no easy matter. Sceptical though I was, I could not get Pauline’s curious production out of my head, and the more I thought of it the more inexplicable seemed its coincidence with the chart. The subconscious mind, with its amazing memory, its dramatic faculty, its unexpected invasion of the surface consciousness in certain types, was not then the commonplace of psychology that it is now—or I should probably have referred the whole thing to the combination of a casual, apparently unheeding, glance at the chart with a memory of some of her brother’s remarks about “Treasure Island,” automatically and dramatically reproduced. As it was, I could formulate no explanation that satisfied me—though I utterly disbelieved in the ghost of a piratical John Dawson, of which the two Vandermeulens were now fully persuaded.

The next day found us steaming steadily westward. Father and son could talk of nothing else but their fancied buried treasure and their plans for digging it up without taking the crew of the yacht into their confidence. Mrs. Vandermeulen hovered round her daughter, horribly anxious of she knew not what, but—after having been once silenced by a peremptory oath from her husband—afraid to make further protest. Pauline herself sat all day in a deck-chair, more silent even than usual, staring dreamily across the empty sea in a reverie which ignored us all. Naturally, I watched her closely. But, except that her eyes had a kind of haunting fear in them, she seemed perfectly normal. Evidently the occurrence of the previous night had shocked her profoundly, for once, when I casually mentioned it, she shuddered and implored me not to speak of it again. The fear of the uncanny in herself stared out of her eyes as she entreated me.

This dreamy absorption in herself continued until supper time that evening. Throughout the meal, I do not think she uttered a single word. She seemed not even to hear the conversation around her, but toyed listlessly with her food and finally ceased to eat long before the others had finished. Watching her with a professionally interested observation, I was uneasy. She had leaned back in her chair, was gazing straight before her with wide-open eyes. Suddenly I noticed that they had glazed over. All expression faded out of her face. The arm that rested on the salmon-table stiffened into a cataleptic sort of rigidity.

Her mother was also anxiously watching her.

“Pauline!” she cried. “Are you ill?”

There was no answer. The girl sat like a statue. Mrs. Vandermeulen glanced at me in wild alarm, silently imploring my intervention. Old Vandermeulen and his son were hotly arguing the desirability or otherwise of informing Captain Higgins of their plans, and took no notice of us.

I got up from my seat and went round the table to the girl. I lifted up her lifelessly heavy arm with my fingers on her pulse. It was normal.
