One morning in the first week of the return voyage when John Dolittle and his animals were all sitting at breakfast round the big table in the cabin, one of the swallows came down and said that he wanted to speak to the Doctor.  
John Dolittle at once left the table and went out into the passage where he found the swallow-leader himself, a very neat, trim, little bird with long, long wings and sharp, snappy, black eyes. Speedy-the-Skimmer he was called—a name truly famous throughout the whole of the feathered world. He was the champion flycatcher and aerial of Europe, Africa, Asia, and America. For years every summer he had won all the flying races, having broken his own record only last year by crossing the Atlantic in eleven and a half hours—at a speed of over two hundred miles an hour.
 
"Well, Speedy," said John Dolittle. "What is it?"
 
"Doctor," said the little bird in a mysterious whisper, "we have sighted a canoe about a mile ahead of the ship and a little to the , with only a black woman in it. She is weeping bitterly and isn't paddling the canoe at all. She is several miles from land—ten, at least, I should say—because at the moment we are crossing the Bay of Fantippo and can only just see the shore of Africa. She is really in dangerous straits, with such a little bit of a boat that far out at sea. But she doesn't seem to care. She's just sitting in the bottom of the canoe, crying as if she didn't mind what happens to her. I wish you would come and speak to her, for we fear she is in great trouble."
 
"All right," said the Doctor. "Fly slowly on to where the canoe is and I will the ship to follow you."
 
So John Dolittle went up on deck and by the boat after the guiding swallows he presently saw a small, dark canoe rising and falling on the waves. It looked so tiny on the wide face of the waters that it could be taken for a log or a stick—or, indeed, missed altogether, unless you were close enough to see it. In the canoe sat a woman with her head bowed down upon her knees.
 
"What's the matter?" shouted the Doctor, as soon as he was near enough to make the woman hear. "Why have you come so far from the land? Don't you know that you are in great danger if a storm should come up?"
 
Slowly the woman raised her head.
 
"Go away," said she, "and leave me to my sorrow. Haven't you white men done me enough harm?"
 
John Dolittle the boat up closer still and continued to talk to the woman in a way. But she seemed for a long time to mistrust him because he was a white man. Little by little, however, the Doctor won her confidence and at last, still weeping bitterly, she told him her story.

These were the days, you must understand, when slavery was being done away with. To capture, to buy or to sell slaves had, in fact, been forbidden by most governments. But certain bad men still came down to the west coast of Africa and captured or bought slaves secretly and took them away in ships to other lands to work on cotton and tobacco . Some African kings sold prisoners they had taken in war to these men and made a great deal of money that way.
 
Well, this woman in the canoe belonged to a tribe which had been at war with the king of Fantippo—an African kingdom on the coast near which the swallows had seen the canoe.
 
And in this war the King of Fantippo had taken many prisoners, among whom was the woman's husband. Shortly after the war was over some white men in a ship had called at the Kingdom of Fantippo to see if they could buy slaves for tobacco plantations. And when the king heard how much money they were willing to give for black slaves he thought he would sell them the prisoners he had taken in the war.
 
This woman's name was Zuzana and her husband was a very strong and fine-looking man. The King of Fantippo would have kept Zuzana's husband for this reason, because he liked to have strong men at his court. But the slave traders also wanted strong men, for they could do a lot of work on the plantations. And they offered the King of Fantippo a high price for Zuzana's husband. And the king had sold him.
 
Zuzana described to the Doctor how she had followed the white man's ship a long way out in a canoe, them to give her back her husband. But they had only laughed at her and gone on their way. And their ship had soon passed out of sight.
 
That was why, she said, she hated all white men and had not wanted to speak to the Doctor when he had hailed her canoe.
 
The Doctor was dreadfully angry when he had heard the story. And he asked Zuzana how long ago was it that the slaver's ship bearing her husband had left.
 
She told him it was half an hour ago. Without her husband, she said, life meant nothing to her, and when the ship had passed from view, going along the coast, she had burst into tears and just let the canoe drift, not even having the heart to paddle back to land.
 
The Doctor told the woman that no matter what it cost he was going to help her. And he was all for speeding up his ship and going in chase of the slave boat right away. But Dab-Dab the duck warned him that his boat was very slow and that its sails could be easily seen by the slavers, who would never allow it to come near them.
 
So the Doctor put down his anchor and, leaving the ship where it was, got into the woman's canoe. Then, calling to the swallows to help him as guides, he set off northward along the coast, looking into all the bays and behind all the islands for the slave ship which had taken Zuzana's husband.
 
But after many hours of fruitless search night began to come on and the swallows who were as guides could no longer see big distances, for there was no moon.
 
Poor Zuzana began weeping some more when the Doctor said he would have to give up for the night.
 
"By morning," said she, "the ship of the wicked slave will be many miles away and I shall never get my husband back. ! Alas!"
 
The Doctor comforted her as best he could, saying that if he failed he would get her another husband, just as good. But she didn't seem to care for that idea and went on , "Alas! Alas!"
 
She made such a noise that the Doctor couldn't get to sleep on the bottom of the canoe—which wasn't very comfortable, anyway. So he had to sit up and listen. Some of the swallows were still with him, sitting on the edge of the canoe. And the famous Skimmer, the leader, was also there. They and the Doctor were talking over what they could do, when suddenly the Skimmer said, "Sh! Look!" and out to the over the dark, heaving sea.
 
Even Zuzana stopped her wailing and turned to look. And there, away out on the dim, black edge of the ocean, they could see a tiny light.
 
"A ship!" cried the Doctor.
 
"Yes," said Speedy, "that's a ship, sure enough. I wonder if it's another slave ship."
 
"Well, if it's a slave ship, it's not the one we're looking for," said the Doctor, "because it's in the wrong direction. The one we're after went northward."
 
"Listen, Doctor," said Speedy-the-Skimmer, "suppose I fly over to it and see what kind of a ship it is and come back and tell you. Who knows? It might be able to help us."
 
"All right, Speedy. Thank you," said the Doctor.
 
So the Skimmer sped off into the darkness toward the tiny light far out to sea, while the Doctor fell to wondering how his own ship was getting on which he had left at anchor some miles down the coast to the southward.
 
After twenty minutes had gone by John Dolittle began to get worried, because the Skimmer, with his tremendous speed, should have had time to get there and back long ago.
 
But soon with a of the wings the famous leader made a neat circle in the darkness overhead and dropped, light as a feather, on to the Doctor's knee.
 
"Well," said John Dolittle, "what kind of a ship was it?"
 
"It's a big ship," panted the Skimmer, "with tall, high masts and, I should judge, a fast one. But it is coming this way and it is sailing with great care, afraid, I imagine, of shallows and sandbars. It is a very neat ship, smart and new-looking all over. And there are great big guns—cannons—looking out of little doors in her sides. The men on her, too, are all well dressed in smart blue clothes—not like ordinary at all. And on the ship's was painted some lettering—her name, I suppose. Of course, I couldn't read it. But I remember what it looked like. Give me your hand and I'll show you."
 
Then the Skimmer, with one of his claws, began tracing out some letters on the Doctor's palm. Before he had got very far John Dolittle sprang up, nearly overturning the canoe.
 
"H. M. S.!" he cried. "That means Her Majesty's Ship. It's a man-o'-war—a navy . The very thing we want to deal with slave traders!"
