“Don’t then,” said Ranni with a grin. He pulled the rugs closely over the children and went back to his seat beside Pilescu.

Nora and Peggy and Paul found that their eyes closed themselves — they simply wouldn’t keep open. In three seconds they were all sound asleep. The other two boys did not take much longer, excited though they were.

Ranni nudged the pilot and Pilescu’s dark eyes twinkled as he looked round at the quiet children.

He and Ranni talked in their own language, as the plane roared through the night. They had travelled hundreds of miles before daylight came. It was marvellous to see the sun rising when dawn came.

The sky became full of a soft light that seemed alive. The light grew and changed colour. Both pilots watched in silence. It was a sight they had often seen and were never tired of.

Golden light filled the aeroplane when the sun showed a golden rim over the far horizon. Ranni switched off the electric lights at once. The world lay below, very beautiful in the dawn.

“Blue and gold,” said Ranni to Pilescu, in his own language. “It is a pity the children are not awake to see it.”

“Don’t wake them, Ranni,” said Pilescu. “We may have a harder time in front of us than they know. I am hoping that we shall turn and go back, once the children realise that we cannot possibly find their parents. We shall not stay in Africa very long!”

The children slept on. When they awoke it was about eight o’clock. The sun was high, and below the plane was a billowing mass of snowy whiteness, intensely blue in the shadows.

“Golly! Is it snow?” said Paul, rubbing his eyes in amazement. “Pilescu, I asked you to fly to Africa, not to the North Pole!”
