But hour after hour went by and still the ship went rushing on, over the same flat, flat sea; and no land anywhere came in sight.

And now the animals gave up chattering and sat around silent, anxious and miserable. The little boy again grew sad. And on Jip's face there was a worried look.

At last, late in the afternoon, just as the sun was going down, the owl, Too-Too, who was perched on the tip of the mast, suddenly startled them all by crying out at the top of his voice, "Jip! Jip! I see a great, great rock in front of us--look--way out there where the sky and the water meet. See the sun shine on it--like gold! Is the smell coming from there?"

And Jip called back, "Yes. That's it. That is where the man is.

--At last, at last!"

And when they got nearer they could see that the rock was very large--as large as a big field.

No trees grew on it, no grass--nothing. The great rock was as smooth and as bare as the back of a tortoise.

Then the Doctor sailed the ship right round the rock. But nowhere on it could a man be seen. All the animals screwed up their eyes and looked as hard as they could; and John Dolittle got a telescope from downstairs.

But not one living thing could they spy-- not even a gull, nor a star-fish, nor a shred of sea-weed.

They all stood still and listened, straining their ears for any sound. But the only noise they heard was the gentle lapping of the little waves against the sides of their ship.

Then they all started calling, "Hulloa, there!

--HULLOA!" till their voices were hoarse.

But only the echo came back from the rock.

And the little boy burst into tears and said, "I am afraid I shall never see my uncle any more! What shall I tell them when I get home!"

But Jip called to the Doctor, "He must be there--he must--HE MUST!

The smell goes on no further. He must be there, I tell you! Sail the ship close to the rock and let me jump out on it."

So the Doctor brought the ship as close as he could and let down the anchor. Then he and Jip got out of the ship on to the rock.

Jip at once put his nose down close to the ground and began to run all over the place. Up and down he went, back and forth--zig-zagging, twisting, doubling and turning. And everywhere he went, the Doctor ran behind him, close at his heels--till he was terribly out of breath.

At last Jip let out a great bark and sat down.

And when the Doctor came running up to him, he found the dog staring into a big, deep hole in the middle of the rock.

"The boy's uncle is down there," said Jip quietly. "No wonder those silly eagles couldn't see him!--It takes a dog to find a man."

So the Doctor got down into the hole, which seemed to be a kind of cave, or tunnel, running a long way under the ground. Then he struck a match and started to make his way along the dark passage with Jip following behind.

The Doctor's match soon went out; and he had to strike another and another and another.

At last the passage came to an end; and the Doctor found himself in a kind of tiny room with walls of rock.

And there, in the middle of the room, his head resting on his arms, lay a man with very red hair--fast asleep!

Jip went up and sniffed at something lying on the ground beside him. The Doctor stooped and picked it up. It was an enormous snuff- box. And it was full of Black Rappee!
