Devereux made no reply, and for some time seemed very unwilling to converse. Paul earnestly wished that O’Grady would return, or that Devereux would give him leave to go in search of fresh water, which he thought might be found further in the interior. Devereux, whose eyes had been shut, at last looked up.

“Oh, for a glass of water, Gerrard! None but those who have been placed as we are know its true value,” he whispered.

“Let me go and try to find some, sir,” said Paul. “I see a large shell a few yards off; it will carry as much as you can drink. And now that the light is stronger, I observe in the distance some shrubs or low trees, and I cannot but hope that water will be found near them.”

“Then go,” said Devereux; “but take care that you can find me again.”

Paul looked about, and saw a small spar floating on to the beach. Without hesitation, he ran into the water to bring it out. He seized the prize, and was dragging it on shore, when a large monster darted towards him. He struck out the spar with all his force in the direction of the creature. It was almost torn from his grasp, and he was nearly dragged, with his face down, into the water; but he held on manfully, and sprang back. He just saw a pair of fierce eyes, two rows of sharp teeth, and a glance of white skin, convincing him that he had narrowly escaped from the jaws of a ravenous shark. He felt also that he had additional cause for thankfulness at having escaped the sharks when he and his companions had been so long helplessly tumbled about in the waves during the night. “Poor Alphonse and the rest! what has been their fate?” he thought. He did not tell Devereux of his narrow escape; but planting the pole in the sand, with a handkerchief tied to the top of it, he set off towards the spot where he hoped to find water. Devereux wished him good speed.

“You will easily find me again,” he said, as Paul left him. Paul hurried on. The ground was composed of sand and rock, with scarcely any vegetation. The spot where he had left Devereux was the summit of a bank; the space he was traversing looked as if it had been recently covered by the sea. The trees were much farther off than he had fancied. The heat of the sun increased; he felt very weak and hungry, and it was with difficulty that he could make his way through the deep sand.

“If I do not go on, poor Mr Devereux will die of thirst, and water must be found,” he said to himself whenever he found his resolution flagging. A famous word is that must. We must do what has to be done. We must not do what ought not to be done. Paul struggled on in spite of the heat, and thirst, and hunger, and weariness, and the strange creatures which crawled out from the crevices in the rocks, and ran along the hot sand. He had no time to examine them. At length he found that he was rising on the side of another bank, and what had seemed mere shrubs in the distance, now assumed the appearance of a group of tall cocoa-nut trees. “Should there be no water below, I shall find what will be almost as refreshing,” thought Paul, as he hurried on, almost forgetting his fatigue in his eagerness to reach the spot. The sand, however, seemed deeper and hotter than any he had before traversed. Below the cocoa-nut trees there were low shrubs and some herbage. These indicated water without doubt. He ran on. He stopped and hesitated. There was a long, low building, capable of holding a number of persons. If it was at present occupied, what reception could he expect to meet from its inmates? He had read about savage Caribs, and buccaneers, and pirates, and he thought that, possibly, the people in the hut might be one or the other. He advanced cautiously, expecting every moment to see some one come out of the hut. “I am but a boy, and however bad they may be, they will not hurt me; and I must have the water at all events—for water there must be, or the hut would not have been built on that spot.” Saying this, he hurried on, treading lightly, “The people may be asleep, and I may get the water and be away without any one seeing me,” he thought. He passed the door of the hut. Before him appeared a tank cut in the coral rock, with the pure clear water bubbling up in the middle of it. Stooping down, he quickly washed out his shell, and then took a long, delicious draught. He felt as if he could never take enough. He did not forget his companions; and while he was considering how little the shell could carry, his eye fell on an iron pot by the side of the tank. He stooped down and filled it, and was carrying it off, when the door of the hut opened, and a woolly head with a hideous black face popped out, and a voice which sounded like a peal of thunder, the roll of a muffled drum, and the squeak of a bagpipe, mingled in one, shouted out to him in a language he could not understand. Instead of running away, Paul turned round and asked the negro what he wanted. The latter only continued growling as before, and making hideous faces, while his eye glanced at the can. Paul made signs that he was only borrowing it, and would bring it back. He, however, did not venture within grasp of the unattractive-looking negro, who showed no inclination to follow him. The reason was soon apparent, for, as the black came rather more out of the doorway, Paul perceived that he had lost both his legs, and stood upon two wooden stumps. No one else appeared to be moving inside the hut, and Paul concluded, therefore, that the black was its only inmate. To avoid that unprepossessing individual, he had made a circuit, and as he looked about to ascertain the direction he was to take, he discovered that he was near the head of a long narrow lagoon, or gulf, which ran up from the sea. He had no time to examine it, as he was anxious to get back to Devereux. He ran on as fast as he could without spilling the water. He thought that he knew the way. He stopped. He feared that he had mistaken it. He looked back at the tall cocoa-nut trees, and wished that he had brought some of the fruit with him; but then he remembered that alone he could not have got it, and that the black, might possibly not have chosen to give him any. Again and again he stopped, fearing that he must be going in a wrong direction. The flagstaff could nowhere be seen. “Poor Mr Devereux! what will become of him should I miss him?” he said frequently to himself, as he worked his way on through the heavy sand. At last the looked-for signal appeared above the top of a bank. Devereux was lying where he had left him, but seemed unconscious of his approach. “Was he asleep—or, dreadful thought! could he be dead?” He ran on, nearly spilling the precious water in his eagerness. He called. Devereux did not answer. He knelt down by his side. His eyes were closed, and his arms were helplessly stretched out like those of the dead. Paul moistened his lips, and by degrees got them far enough apart to pour some water down his throat. At length, to Paul’s great joy, Devereux opened his eyes.

“Where is O’Grady?” he asked, and then continued—“Ah! Gerrard, is that you? Where did you get the water? It is delicious! delicious!”

In a short time Devereux appeared to be sufficiently recovered to understand what was said to him; and while Paul was giving him an account of his adventures, O’Grady was seen running towards them. He arrived almost breathless, with his arms full of shell-fish, which he threw before them on the ground.

“I have had hard work to get them, but there is no lack of more on the lee side of the island, so we shall not starve,” he exclaimed. “But set to and eat, for it won’t do to wait for cooking, as we have no means of kindling a fire. When we have broken our fast, I will tell you what I have seen.”
