THE BEAVER CALL
"That's Tommy!" exclaimed Will.
"I never knew that he belonged to the Wolf Patrol!" George observed.
"He might give the call without belonging to the Patrol!" urged Will.
The boys listened, but the sound was not repeated, although they called out the names of their chums and gave the Beaver call repeatedly.
"I guess it was a dream," George suggested.
"Then it was the most vivid dream I ever had!" Will declared.
They rowed about the chamber for some moments, searching for the source of the call, but to no purpose.
"Let's go back to the shaft," urged George.
"I'm agreeable," answered Will. "The only question now is whether we can find the shaft. The water is so deep that all branches of the mine look alike to me!"
