“We won’t stay very long,” said Mr. Todd. “I’ll just show the children the pile of ice and then we’ll go back to the front part of the cave where the air is warmer. This shower will soon be over and we can go outside again.”

They walked on a little farther and suddenly Rose cried:

“Oh, I see it! I see a big pile of ice!”

The light from Farmer Joel’s blazing stick glittered on a sparkling mass of ice and snow in the deepest, darkest part of the cave.

“Is it real?” asked Mun Bun.

“Touch it and see,” advised his father.

Mun Bun put his little hand on the sparkling pile. He drew it quickly back with a murmur of wonder.

“Oh, it’s terribly cold!” he exclaimed.

“It’s real ice, all right,” laughed Farmer Joel.

“How does it get in here?” Russ asked.
