"Sartin sure of it!" declared Abe. "Put her down, Tom! Put her down!"

"It's quite a surprise party to 'em," observed Ned Newton.
"Yes, I hope they don't spring one on us," added Tom.
Down and down went the Red Cloud lower and lower into the valley.
"There are ice caves there!" cried Mr. Parker, pointing to the curiously rounded and hollow hummocks. "Lots of them!"
"And larger than the others!" added Mr. Damon.
The airship was now moving slowly, for Tom wanted to pick out a good landing place. He saw a smooth stretch of the ice just ahead of him, in front of an immense ice cave.
"I'll make for that," he told Ned.
