The Captain had a revolver. He did not want to shoot the chief, but thought he might as well frighten him. He drew his revolver and fired it into the air. The noise of the shot echoed round the mountains in a most terrifying manner. The chief jumped with fright. All the Mountain Folk began to jabber and shout.

But one, cleverer than the others, aimed his spear at Captain Arnold. The shining weapon flew through the air, struck the gun in the Captain’s hand, and sent it flying to ground with a clang. None of the Mountain Folk dared to pick it up, and Captain Arnold did not dare to either — for a different reason! He was not afraid of the revolver — but he was afraid of the spears around him!

The chief shouted out a harsh order, and twelve men ran up with spears. They took hold of all the little company, and before ten minutes had gone by, each grown-up and child was bound with thin, strong ropes!

“What will they do with us?” said Nora, who was very angry because her wrists had been bound too tightly.

Nobody knew. But it was plain that the little party were to be taken below into the heart of the mountain. They were not to be left on the summit.

“I expect the chief is afraid we will do something to his beloved sun if he leaves us up here,” said Jack. “I wish another eclipse would happen! What a shock it would give them all!”

The chief gave orders for the captives to be taken down the shining stairway — but just as they were about to go, there came a most extraordinary noise!

At first it was far away and quiet — a little humming — but soon it grew louder and louder, and the mountain-side echoed with the sound of throbbing.

“R-r-r-r-r-r-r!” went the noise. “R-r-r-r-r-r! R-r-r-r-r-r-r!”

The Folk of the Secret Mountain stopped and listened, their eyes wide with amazement. This was a strange noise. What could it be?
