Prince Paul pricked up his ears. “Why don’t you like it, Ranni?” he asked. Ranni would not tell him. All of them watched the sun. It disappeared suddenly over the edge of the world. At once the countryside was plunged into darkness, the valley and mountains disappeared from sight, and only the shimmering of the golden floor lighted the summit of the queer mountain.

A tall, red-haired man went into the centre of the shining courtyard, and spoke loudly and violently. Ranni listened and tried to understand as much as he could.

“What is he saying?” asked Mike.

“As far as I can make out he is asking the sun to stay away and let the rain come,” said Ranni. “It seems that the rain is very much overdue, and these people are praying to the sun to dress himself in the thick clouds that will bring the rain they want. I expect they have crops somewhere on the mountain-side and are in danger of losing them if the rains don’t come!”

That night the little party slept on rugs in the cold, wind-swept temple. They were all alone on the mountaintop, for their guards disappeared behind the yellow sliding door, slid it back into place again and fastened it with great long bolts. Ranni and Pilescu explored the temple, the courtyards and the corridor by the light of a torch — but there was no other door down into the mountain save the big shining one. It was as impossible to leave the top of the mountain as it had been to leave their underground room the night before.

How everyone wondered where Jack and Mafumu were, and if Captain and Mrs. Arnold were anywhere near! They did not know that the four were together! When they had left the sun-trap, they had taken the passage that led inwards, and walking as quietly as they could, had come across a queer collection of store-rooms. No one was there, so they had explored them thoroughly.

In one store-room, cut out of the solid rock, were dyes and paints of all kinds. Captain Arnold examined them closely. “Look,” he said, “this explains the red hair of the Folk of the Mountain. This is a very strong red dye, and these people use it for their hair, to scare any strangers they meet. And see — this is the curious yellow pigment they use for their skins!”

Everyone looked at the flat pots he was holding. They were full of the yellow ointment that the Secret Mountain Folk used on their skin! No wonder the Folk looked so very queer! They dyed their hair and painted their skin yellow!

When Jack knew this he no longer felt afraid of the curious appearance of the mountain people. Golly! If it was only paint and grease there was nothing strange to be afraid of! He took one of the flat pots of yellow grease and put it into his pocket. “It will be interesting to take home!” he said cheerfully.

“If we ever do get home,” thought Captain Arnold to himself. They left the store-rooms and went on down a curving passage that had a very high roof. Soon they heard a noise — and they came to the banks of the underground river, which swirled along through the mountain, black and swift. It was strange to see it there, running through an enormous cave.
