“And who tore his coat to rags squeezing through a hawthorn hedge, trying to get away from an angry cow?” asked Jack.

“I did,” said Paul. “But then, here, I am like you. I learn to behave differently. When you go to Baronia you, too, will have different manners. You must kiss my mother’s hand, for instance.”

Mike and Jack looked at him in alarm. “I say! I’m not much good at that sort of thing!” said Jack.

“And you must learn to bow — like this,” said the little prince, thoroughly enjoying himself. He bowed politely from his waist downwards, stood up and brought his heels together with a smart little click. The girls giggled.

“It will be fun to see Mike and Jack doing things like that,” said Nora. “You’d better start practising now, Mike. Come on — bow to me. And, Jack, you kiss my hand!”

The boys scowled. “Don’t be an idiot,” said Mike, gruffly. “If I’ve got to do it, I will do it — but not to you or Peggy.”

“I don’t expect it will be as bad as Paul makes out,” said his mother, smiling. “He is just pulling your leg. Look at him grinning!”

“You can behave how you like,” said Paul, with a chuckle. “But don’t be surprised at Baronian manners. They are much better than yours!”

“Have you all finished tea?” asked Captain Arnold. “I can’t imagine that any of you could possibly eat any more, but I may be wrong.”

“I’ll just have one more piece of cake,” said Mike. “We don’t get chocolate cake like this at school!”

“You’ve had four pieces already,” said his mother. “I am glad I don’t have to feed you all the year round! There you are — eat it up.”

There was very little packing to be done that evening — only night-clothes and tooth-brushes, flannels and things like that. All the children were looking forward to wearing the colourful Baronian clothes. They had seen photographs of the Baronian people, and had very much liked the children’s clothes. They were all so thrilled that it was very difficult to settle down and do anything. They talked to Captain and Mrs. Arnold, played a game or two and then went off to bed.

Not one of them could go to sleep. They lay in their different bedrooms, calling to one another until Mrs. Arnold came up and spoke sternly.

“One more shout — and you don’t go to Baronia!” After that there was silence, and the five children lay quietly in their beds, thinking of the exciting day tomorrow was going to be.

It was wonderful to wake up the next morning and remember everything. Jack sat up and gave a yell to wake the others. It was not long before everyone was dressed and down to breakfast. They were to go to the airport to meet Ranni and Pilescu, the big Baronians, at ten o’clock. All the things they were taking with them went into one small bag.

“Mummy, I’m sorry I won’t see much of you these hols.” said Peggy.

“Well, Daddy and I may fly over to Baronia to fetch you back,” said her mother. “We could come a week or two before it’s time for you to return to school, so we should see quite a bit of you!”

“Oh — that would be lovely!” said Nora and Peggy together, and the boys beamed in delight. “Will you come in the White Swallow?”

The White Swallow was the name given to Captain Arnold’s famous aeroplane. In it he and Mrs. Arnold had flown many thousands of miles, for they were both excellent pilots. They had had many adventures, and this was partly why they liked their children to go off on their own and have their own adventures too.

“It doesn’t do to coddle children too much and shelter them,” said Captain Arnold many a time to his wife. “We don’t want children like that — we want boys and girls of spirit and courage, who can stand on their feet and are not afraid of what may happen to them. We want them to grow up adventurous and strong, of some real use in the world! So we must not say no when a chance comes along to help them to be plucky and independent!”

“If we can grow up like you and Mummy, we shall be all right!” said Peggy. “You tried to fly all the way to Australia by yourselves in that tiny plane — and you’ve set up ever so many flying records. We ought to be adventurous children!”

“I think you are,” said her mother, with a laugh. “You’ve certainly had some marvellous adventures already — more than most children have all their lives long!”

When the car drew up at the door to take the children to the airport, they all clattered down the steps at once. “It’s a good thing it’s a big car!” said Mike. “Seven of us is quite a crowd!”

Everyone got in. The car set off at a good speed, and soon came to the big airport. It swept in through the gates. Mike, who was looking out of the window, gave a loud shout.

“There’s your aeroplane, Paul! I can see it. It’s the smartest one on the air-field.”

“And the loveliest,” said Nora, looking in delight at the beautiful plane towards which they were racing. It was bright blue with silver edges, and it shone brilliantly in the sun. The car stopped a little way from it. Everyone got out. Paul gave a yell.

“There’s Pilescu! And Ranni! Look, over there, behind the plane!”

The two big Baronians had heard the engine of the car and they had come to see if it was the children arriving. Pilescu gave a deep-throated shout.

“Paul! My little lord!”

Paul raced over the grass to Pilescu. The big red-bearded man bowed low and then lifted the boy up in his strong arms.

“Pilescu! How are you? It’s grand to see you again,” said Paul, in the Baronian language that always sounded so strange to the other children.

Pilescu was devoted to the little prince. He had held him in his arms when he was only a few minutes old, and had vowed to be his man as long as he lived. His arms pressed so tightly round the small boy that Paul gasped for breath.

“Pilescu! I can’t breathe! Let me down,” he squealed. Pilescue grinned and set him down. Paul turned to Ranni, who bowed low and then gave him a hug like a bear, almost as tight as Pilescu’s.

“Ranni! Have you got any of the chocolate I like so much?” asked Paul. Ranni put his hand into his pocket and brought out a big packet of thick chocolate, wrapped in colourful paper. It had a Baronian name on it. Paul liked it better than any other chocolate, and had often shared it with Mike and Jack, when a parcel had arrived for him from Baronia.

Ranni and Pilescu welcomed the other children, beaming in delight to see them all, and Captain and Mrs. Arnold too. They had all shared a strange adventure in Africa, hidden in a Secret Mountain, and it was pleasant to be together again.

“Look after all these rascals, Pilescu,” said Mrs. Arnold, as she said goodbye to the excited children. “You know what monkeys they can be!”

“Madam, they are safe with me and with Ranni,” said Pilescu, his red beard flaming in the sun. He bowed from his waist, and took Mrs. Arnold’s small hand into his big one. He kissed it with much dignity. Mike felt perfectly certain he would never be able to kiss anyone’s hand like that.

“Is the plane ready?” asked Captain Arnold, climbing into the cockpit to have a look round. “My word, she is a marvellous machine! I’ll say this for Baronia — you have some mighty fine designers of aircraft! You beat us hollow, and we are pretty good at it, too.”

All the children were now munching chocolate, talking to Ranni. The big bear-like man was happy to see them all again. Nora and Peggy hung on to him, remembering the thrilling, dangerous days when they had all been inside the Secret Mountain in Africa.

A mechanic came up and did a few last things to the engine of the great aeroplane. In a minute or two the engines started up and a loud throbbing filled the air.

“Doesn’t it sound lovely?” said Mike. “We’re really going!”

“Get in, children,” said Pilescu. “Say your goodbyes — then we must go.”
