How long we had been asleep I do not know.  I was awoke by a terrific crash and loud cries and shrieks.  Jerry and I sprung up, so indeed did everybody below, and rushed on deck.  It was very dark; but from the way the ship heaved and lurched, and the sheets of foam which flew over her, we knew that she was among the breakers, and striking hard on a reef. The fore-mast and main-mast had gone by the board.  The mizzen-mast alone stood.  That fell soon after we got on deck, crushing several people beneath it.  Anxiously we hunted about shouting for Cousin Silas, followed by Old Surley, who, since we came on board, scarcely ever left our heels.  We naturally sought him for advice.  It was, indeed, a relief to us to find him unhurt.  In a short time we discovered the doctor and Ben.  We clustered together, holding on by the bulwarks; for every now and then a sea came and washed over the decks, and we ran great risk of being carried away.  Nothing could we see on either side beyond the white roaring breakers.  Cousin Silas said that he was certain we must have been driven some way on the reef, or the sea would have broken more completely over us, and no one could have hoped to escape.  Several people had already been washed overboard, and had been lost or killed by the falling masts; but who they were we could not tell.  What, also, had become of the captain we did not know.  He had not, that we could discover, come on deck.  Perhaps, all the time he was below, unconscious of what had occurred.  All we could do was to cling on where we were, till with daylight we should be able to tell our position.  Every now and then we felt the ship lifting, and it appeared as if she was driving gradually over the reef.  Another danger, however, now presented itself--we might drive over the reef altogether, and sink on the other side!  We strained our eyes through the darkness; but, surrounded as we were with spray, it was impossible to distinguish the shore, even though it might be near at hand.  If there was no land, our lot would indeed be sad; for, wherever we were, it was clear that the ship would be totally lost, and, as far as we could discover, all our boats were destroyed.  After two or three hours passed in dreadful suspense, though it appeared as if the whole night must have elapsed, the ship became more steady, and the sea broke over her less violently. "We must get a raft made," exclaimed Cousin Silas.  The men seemed to look instinctively to him for orders, and willingly obeyed him.  All hands set to work, some to collect the spars which had not been washed overboard, others to cut away the bulwarks and to get off the hatches-- indeed, to bring together everything that would serve to form a raft. Dark as it was they worked away; for they knew that when the tide again rose the ship might be washed over the reef and sink, or go to pieces where she lay.  How eagerly we watched for daylight to complete our work!  The dawn at length came; and as the mists of night rolled off, we saw before us a range of lofty mountains, of picturesque shapes, rising out of a plain, the shore of which was not more than a quarter of a mile off.  As the sun rose a rich landscape was revealed to us, of cocoa-nut groves, and taro plantations, and sparkling streams, and huts sprinkled about in the distance.
