“Come on,” urged Fred, now also keenly excited.
Outside the cave, Grant sat puzzling over the numbers. Most of his time he now spent in this way, and though he was apparently no nearer a solution than when he had started, his determination was stronger than ever.
“Where are you two fellows going?” he demanded as John and Fred rushed past the spot where he was seated.
“Just up on top of the hill,” said John evasively. He and Fred had decided not to tell any of the others of their discovery until they had investigated it thoroughly themselves.
“You seem to be in an awful hurry,” remarked Grant. “What’s up?”
“Tell you later,” answered John, and they quickly passed out of Grant’s sight. A moment more and they had arrived at the top of the opening which led down into the cave.
“I can’t see anything from here,” exclaimed John, after a hasty examination. “The shadow of my head gets right in the way and I can’t see a thing.”
“Let me look,” urged Fred, but he could make out nothing either.
“I tell you what to do,” he exclaimed a moment later. “Hang onto my feet so I won’t fall and get wedged in there, and then lower me into the hole.”
“That’s a good scheme,” said John eagerly. “You’re little and skinny and ought to be able to get in there all right.”
