BY the edge of the river they stopped and said farewell.
This took a long time, because all those thousands of monkeys wanted to shake John Dolittle by the hand.
Afterwards, when the Doctor and his pets were going on alone, Polynesia said,
"We must tread softly and talk low as we go through the land of the Jolliginki. If the King should hear us, he will send his soldiers to catch us again; for I am sure he is still very angry over the trick I played on him."
"What I am wondering," said the Doctor, "is where we are going to get another boat to go home in.... Oh well, perhaps we'll find one lying about on the beach that nobody is using. 'Never lift your foot till you come to the stile.'"
When they came to the beach they saw Polynesia and Chee-Chee waiting for them on the rocks near the ship.
Then the pushmi-pullyu, the white mouse, Gub-Gub, Dab-Dab, Jip and the owl, Too-Too, went on to the ship with the Doctor. But Chee-Chee, Polynesia and the crocodile stayed behind, because Africa was their proper home, the land where they were born.
And when the Doctor stood upon the boat, he looked over the side across the water. And then he remembered that they had no one with them to guide them back to Puddleby.
The wide, wide sea looked terribly big and lonesome in the moonlight; and he began to wonder if they would lose their way when they passed out of sight of land.
But even while he was wondering, they heard a strange whispering noise, high in the air, coming through the night. And the animals all stopped saying Good-by and listened.
The noise grew louder and bigger. It seemed to be coming nearer to them—a sound like the Autumn wind blowing through the leaves of a poplar-tree, or a great, great rain beating down upon a roof.
And Jip, with his nose pointing and his tail quite straight, said,
"Birds!—millions of them—flying fast—that's it!"
And then they all looked up. And there, streaming across the face of the moon, like a huge swarm of tiny ants, they could see thousands and thousands of little birds. Soon the whole sky seemed full of them, and still more kept coming—more and more. There were so many that for a little they covered the whole moon so it could not shine, and the sea grew dark and black—like when a storm-cloud passes over the sun.
And presently all these birds came down close, skimming over the water and the land; and the night-sky was left clear above, and the moon shone as before. Still never a call nor a cry nor a song they made—no sound but this great rustling of feathers which grew greater now than ever. When they began to settle on the sands, along the ropes of the ship—anywhere and everywhere except the trees—the Doctor could see that they had blue wings and white breasts and very short, feathered legs. As soon as they had all found a place to sit, suddenly, there was no noise left anywhere—all was quiet; all was still.
And in the silent moonlight John Dolittle spoke:
"I had no idea that we had been in Africa so long. It will be nearly Summer when we get home. For these are the swallows going back. Swallows, I thank you for waiting for us. It is very thoughtful of you. Now we need not be afraid that we will lose our way upon the sea.... Pull up the anchor and set the sail!"
When the ship moved out upon the water, those who stayed behind, Chee-Chee, Polynesia and the crocodile, grew terribly sad. For never in their lives had they known any one they liked so well as Doctor John Dolittle of Puddleby-on-the-Marsh.
And after they had called Good-by to him again and again and again, they still stood there upon the rocks, crying bitterly and waving till the ship was out of sight.
