He was abundantly thankful, however, for the pineapple. Leaving his clothing, except his shoes, which he put on again to protect his feet from the sharp rock, he climbed over the broken stone at the base of the rift and found himself once more on the stretch of sand opposite the wrecked whaleboat. The tide was evidently on the ebb, for much that had been covered before was now exposed. He gathered shellfish from the rocks, broke them open, and, restraining his hunger, which was still ravenous, partook sparingly of them.
Again making use of his boards, although he felt so much stronger that he might have dispensed with them, he swam out to the barrier reef and examined the whaleboat again. The lockers forward and aft were practically empty. He did come upon a few scraps of salt meat, which he had been unable to eat before in his consuming thirst; not enough for a meal for an ordinary man, but still very welcome, and these he devoured. There was not a crumb of hard bread left. That he had managed to eat, in spite of his thirst. There was not another thing in the boat except a boat hook, a stout pole with a brass hook on the end, and above the hook a sharp pointed spike. This point had got wedged in the bulkhead of the forward compartment, and the pole, lying under the thwarts, it had not been swept out by the seas which had broken over him. The boat itself was a hopeless wreck. The bottom had been torn out on the reef. Everything that had been in her was gone. If he could break her up, she would make good firewood if he should be able to compass a fire, and the copper air tanks forward and aft, which were still intact, might be of some service if he could ever get them off, which was improbable on account of the lack of tools. Nor would the boat hook be of much use to him. It would make a dangerous weapon in a hand-to-hand encounter, if he should be so unfortunate as to require it, but that was all.
The heat of the sun beating upon him warned him that he would best get back to the shelter of the cliffs and to his clothes. Taking the boat hook, after a last search of the lockers which revealed nothing, he once more swam the lagoon, by force of habit taking the planks which had assisted him before, although now he felt no need of them.
If it had not been for the presence of that woman on the upland indicating that the island was inhabited, he might have husbanded the scraps of salt meat which he had devoured so voraciously, but he reasoned as he ate them that there must be some way to the top, and that once there he would find plenty to eat. That woman could not have dropped from the clouds to the island. She or her forbears must have come up from the sea. If there were a way, he would find it. Retracing his steps, he presently regained the beach at the foot of the waterfall, and finding his clothes dry and free from salt, he put them on again with great comfort and gladness of heart.
Having taken his full meal of fruit, shellfish, and salt meat on the installment plan, as it were, and having prudently refrained from drinking his fill, contenting himself with frequent sips of water, he felt immensely refreshed. He had moved slowly in his weakness and exhaustion, and these various undertakings had used up most of the morning. He could tell from the sun that it was about noon. Selecting a spot on the warm, white sand which the sun had just left, which made a warm and even a luxurious bed for a man who had lain for how many days he could not tell on the hard planks and ribs of a boat in the tossing sea, he threw himself down on his back to rest, intending to begin his explorations in the afternoon. He instantly fell fast asleep.
When he awakened, the sun had set and, looking above and beyond the rocks that circled above him, he could see the stars shining in tropic brilliance in the quiet night sky. He was greatly refreshed by that long, undisturbed sleep on the warm, yielding sand. He was also ravenously hungry again, not famished, but just healthily hungry and thirsty. It was cool in the great cylinder at the bottom of which he lay. He concluded that it would be warmer on the ocean side where the sun had beaten with full power against the rock cliffs all day long. He would pass the night there. Drinking his fill, and drawing his belt a notch or two tighter, he found a sheltered spot protected by an overhang of rock and floored with clean, beautiful sand. He recalled whimsically enough Sancho Panza's sage reflection that "he who sleeps dines." Promising himself a day of exploration in the morning, he was soon asleep again.
Before dawn he made his way back to the waterfall. He was about to explore the harbor or cup when it occurred to him to wait until sunrise. Perhaps she would come again--that spirit of the island. With the first break of day as the splendor of the tropic morning streamed through the rift, he saw again the same radiant, beautiful, golden figure. This time he called. He shouted for help as loudly as he could, not because he had any idea that his words would be understood, but he felt that perhaps the appeal in his voice might be appreciated. He forgot that in his blue clothes he was practically invisible to anyone looking down into the gloom of the deep cup, especially as he stood against the foot of the darkest wall. The distance was great, but the sound of his voice--and it was the first time he had raised it or even spoken since he had landed--sent wild echoes flying which were thrown from wall to wall in almost maniacal ejaculations. Doubtless, they sounded much louder to him than to the woman above, but she was conscious of something unusual, for she started, and as he watched her closely he saw her peer down into the depths. Her vision swept the enclosure, but evidently she had not seen him, and although he called again and again, he finally desisted as she stopped her search, perhaps concluding that some wandering seabird with harsh cry might have sent those echoes flying, for presently she disappeared as before.
Well, he would solve the mystery of her presence when he got to the top of the rock, if he ever did. The first consideration was breakfast. The problem remained unsolved. No kindly brook rolled to his feet another pineapple. True, there were the mussels, but of these he ate sparingly. Then he took his board and launched out into the waters of the harbor. Here and there stretches of beach and piles of rock had collected at the foot of the cliffs which, for a large part of their extent, ran sheer down into the water, the blueness of which showed its depth. The sea water was warmer than the air in the hollow, at least until the sun had tempered it, and the bay was very still. He swam easily through it, landing at each stretch of sand or rock, also inspecting, as he progressed slowly, each fall of cliff that dropped into the water without breaking. Here and there practical ways of ascent seemed to open, but, when surveyed carefully or tried, they ended at greater or less distance upward.
After a careful survey of the entire enclosure, which brought him back finally to the beach of the waterfall where he had started on his little voyage of discovery, he decided that the only possible way to get to the top was by following the line of the waterfall. There was not a great deal of promise in that; still, as it was the only way, it had to be tried. Although he was in much better shape than when he landed, he was not in good condition for violent efforts or exercise had it not been for the impelling physical necessities behind him, to say nothing of the stimulating appeals to his mind of what must be above him.
The boat hook, which he used as he might have an alpenstock, proved of the greatest service. Indeed, he could scarcely have made the difficult ascent without it. It was fortunate for him that he had some experience in mountain climbing in various parts of the world, and that he rejoiced in the possession of a cool head, a steady nerve, and a sure foot. Part of the time he had to climb right through the waterfall. Fortunately, its volume was not great enough to render that impossible, although in the narrow places where the water was concentrated, its beat upon him was tremendous. Sometimes he would stop on a jutting rock with the swift waters roaring down on either side of him, again--in utter despair wondering how it would be humanly possible to go any further. Nevertheless, he persevered, his hope rising higher as he gradually mounted the cliff and surmounted the difficulties. Finally, he lost sense of time and almost everything else. His whole soul was centered upon a desperate determination to get upward.
