But of course the men did not understand him.
Soon the front end of the ship began to go down and down, faster and faster—till the boat looked almost as though it were standing on its head; and the pirates had to cling to the rails and the masts and the ropes and anything to keep from sliding off. Then the sea rushed roaring in through all the windows and the doors. And at last the ship plunged right down to the bottom of the sea, making a dreadful gurgling sound; and the six bad men were left bobbing about in the deep water of the bay.
Some of them started to swim for the shores of the island; while others came and tried to get on to the boat where the Doctor was. But Jip kept snapping at their noses, so they were afraid to climb up the side of the ship.
Then suddenly they all cried out in great fear,
"The sharks! The sharks are coming! Let us get on to the ship before they eat us! Help, help!—The sharks! The sharks!"
And now the Doctor could see, all over the bay, the backs of big fishes swimming swiftly through the water.
