"Why not start now?" urged Tad.
The guide consulted the sun.
"We might. It lacks all of three hours to dark."
There was much enthusiasm in camp. The idea that they were to visit some unexplored caves, dwellings of an ancient people, filled the lads with pleasant expectancy.
Before starting, Mr. Kringle sorted out some strong manila rope and several tent stakes all of which he did up into two bundles. Then he filled the magazine of his rifle, throwing this over his shoulder.
"What's that for?" questioned Ned.
"The gun?"
"Yes."
"Can't tell what we may run into in a cave, you know."
After a final look at the camp all hands set out for the place indicated by Tad. It was only a short distance, so they decided to walk.
