"Tommy was headed for this place!" exclaimed Will. "It's a mystery to me where George disappeared to so suddenly. Of course, we didn't see enough of his wig-wag to know what he intended to say, but we understand there's something amiss."
"There are plenty of caverns here in which one may hide," Chester answered. "There is one just north of this which has several good-sized rooms. Father and I thought of moving to that one."
They passed into the Cave of the Three Bears and found that one hide had been partly removed, and that a huge piece of meat had been taken away.
