f this old boat were sinking we should see the rats
leaving it."

And Jip shouted across from the other ship,

"You great duffers, there are no rats there to leave! They left two
hours ago! 'Ha, ha,' to you, 'my fine friends!'"

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 and 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.

And one great shark came near to the ship, and poking his nose out of
the water he said to the Doctor,

"Are you John Dolittle, the famous animal-doctor?"

"Yes," said Doctor Dolittle. "That is my name."

"Well," said the shark, "we know these pirates to be a bad
lot--especially Ben Ali. If they are annoying you, we will gladly eat
them up for you--and then you won't be troubled any more."

"Thank you," said the Doctor. "This is really most attentive. But I
don't think it will be necessary to eat them. Don't let any of them
reach the shore until I tell you--just keep them swimming about, will
you? And please make Ben Ali swim over here that I may talk to him."

So the shark went off and chased Ben Ali over to the Doctor.

"Listen, Ben Ali," said John Dolittle, leaning over the side. "You
have been a very bad man; and I understand that you have killed many
people. These good sharks here have just offered to eat you up for
me--and 'twould indeed be a good thing if the seas were rid of you. But
if you will promise to do as I tell you, I well let you go in safety."

"What must I do?" asked the pirate, looking down sideways at the big
