As luck had it this time, it landed directly in front of a deep cavernous passage.
Frank felt confident that this would take them out into the ocean.
Accordingly he started the Explorer through the passage.
As they went on, this seemed to widen and deepen.
Very soon they began to leave the ice walls behind.
A great hope sprang up in Frank’s breast.
“Hurrah!” he cried. “I believe we are out of the wilderness!”
“Dat am joyful!” cried Pomp.
“Whurroo!” shouted Barney.
In a few moments more Frank felt assured that they were in the open sea.
