Then she sat up, and, far away in the distance, she saw a round, bright spot that reminded her of a full moon. It seemed to be getting nearer and bigger, and finally she gave a cry of joy and awakened her companion.
"Tot! Oh, Tot!" she called. "We've got to the end at last and are coming out of the tunnel!"
Tot sat up and rubbed his eyes. He gave one careless glance at the opening, and then turned his eyes upon the lunch basket, saying, sleepily, "I'm hungry!"
There would be plenty of time to eat after they were out of the tunnel and in safety.
The boat glided on as gracefully as a swan, and in a few minutes it passed through the jagged rocks that formed the mouth of the tunnel and floated into a broad, open river.
Dot and Tot quickly scrambled upon the seat and looked around them.
