An enormous gong boomed out from the temple. One of the servants of the chief was sounding it. The children had seen it there, but there had been nothing to bang it with — and now it was sounding over the mountain-top, booming its great solemn note all around. The valleys below took up the note and threw it back — and soon, from everywhere around, the echoes came back until it seemed as if the whole earth and sky were filled with the booming of the gong.

At once all the sun-worshippers fell on their knees. The chief waited until the sound of the gong had died away and then he spoke in a loud voice. He brought Prince Paul forward, and the boy stood there on the temple tower, his robes blowing and shining in the wind.

“Captain Arnold, will the eclipse start soon?” asked Jack nervously. He was terribly afraid that something would happen to Paul before they could prevent it. Captain Arnold glanced at his watch.

“It will begin in two minutes,” he said. “Now, I am going to take a hand in this game! Watch me!”

He ran with quick, light steps to the tower. The servants at the entrance were taken by surprise, and he slipped through easily. He raced up the stone steps and in a moment or two was standing beside the chief and Paul.

And then things began to happen! Captain Arnold turned to the great sun and shook his fist at it. He shouted at it! He snatched a knife from his belt and threw it high into the air at the sun! The knife made a great curve in the air and disappeared over the mountainside!

“He kills the sun, he kills the sun!” shouted Mafumu, who suddenly understood what Captain Arnold was pretending to do. The Mountain Folk understood Mafumu’s shout and rose to their feet in alarm and confusion. The servants of the chief ran to capture Captain Arnold — and then a strange thing happened.

A tiny piece seemed suddenly to be bitten out of the sun! A small black shadow appeared at one side! The moon was beginning to pass in front of it, and was hiding a very small piece.

Mafumu saw it and was astonished. He pointed at the sun, and shouted in alarm. “The sun is being eaten! See, see!”

A great silence fell on the mountain-top. Everyone was watching the sun in the sky, covering their faces with their hands, and looking through their fingers to avoid the brilliance. The servants who had come to capture Captain Arnold watched, too, trembling.
