As the dhow appeared to be coming up with him, he saw no necessity for shortening sail, as he hoped that she would close with him before nightfall. By the time the sun went down she had got considerably nearer, and, satisfied that all was right, he stood on. The night came on much darker than usual, but he made out the peak of her triangular sail rising against the sky, and therefore still felt perfectly at ease about her. With so many doubtful characters on board, he would not lie down even for a moment, or allow any of his crew to do so, but kept them together, ready to defeat any attempt the Arabs might make to regain their vessel. As they hoped to reach the island the next day, they might then take a long snooze to make up for their want of sleep. Several times he looked astern, when he saw the other prize still about the same distance as before. Suddenly there came a squall and a downpour of rain, but the wind being right aft, the dhow flew on before it. He, however, thought it prudent to send his men to the halyards, so as to be ready, should the wind increase, to lower the sail, the Arabs showing no inclination to assist in working the vessel. The darkness was greater than ever. The rain indeed, even by itself, was thick enough to hide any objects except close to. In about an hour it cleared off again, when, on looking out for number one prize, he could nowhere distinguish her. "I suppose Gordon and Desmond judged it prudent to lower their sail; they will be hoisting it again presently," he said to himself. Soon afterwards he thought he made her out, rather more over the port quarter than she had been before. Yes, he was certain of it, though she seemed to him farther off than she had hitherto been; still, if the midshipmen had lowered their sail that was to be expected. Adair, still believing that all was right, continued his course, eager to reach the island, and to arrange for despatching the two dhows to the port of adjudication; though he had no doubt that they both would prove lawful prizes. When morning at length broke, dhow number two was nowhere in sight. This made him somewhat anxious, and he regretted that he had not shortened sail at first to allow her to come up. Still the midshipmen had their wits so completely about them, and Bird was so trustworthy a fellow, and fully alive to the importance of keeping an eye on the Arabs, that he had no very serious apprehensions about their safety. A clump of trees rising in the centre of the island at length, to his infinite satisfaction, came in sight. He dropped his anchor in the small harbour formed by the coral reef which circled round the southern portion. He was seen coming in, and one of the boats pulled off to welcome him. He was informed that a vast number of dhows had been boarded, but none as yet captured, all being, as far as could be ascertained, lawful traders; though several had, like his prize, no small number of black passengers on board.
