Red-Cap, who was the eldest, got inside it to see what it was made of.

“Oh! oh!” cried Blue-Cap and Yellow-Cap. “It is moving! Stop! Stop!” But the white thing rolled away down the mountain with poor little Red-Cap inside it; faster and faster it went, and Blue-Cap and Yellow-Cap were left quite behind.

Now little Red-Cap was a brave goblin, but he was rather frightened when the White Thing began to roll so fast. He wondered if it would ever stop, when—Bump! Splash!—he found he was in the water, and something big with a smooth coat was close beside him. It was a kind water-rat who had seen the poor little goblin roll into the water.

“I can swim,” said Mr. Rat. “I will hold you by the collar and take you to dry land again.”

Red-Cap thanked the kind water-rat very much, and they sat down on the bank of the stream to rest. Red-Cap told the rat all about his father and brothers and the Red Feather, and soon Blue-Cap and Yellow-Cap came running up, quite out of breath, but very glad to find their brother quite safe and not even scratched.
