“How’s it coming?” called John after a few moments had elapsed.

“All right,” replied Fred, his voice sounding as if it came from the center of the earth. “I’m spilling a lot of dirt down into the cave though.”

“Never mind that, as long as you don’t lose any of the money.”

“Do you really think there’s any gold or anything in that box?” said Grant.

“I’m sure I don’t know,” John replied. “If Pop were here he’d be sure it was empty.”

“I know it. Isn’t he a regular old gloom lately?”

“He’s not usually that way. At least he never used to be.”

“Something has come over him since we started work on that code. He thinks it’s very silly and that we are foolish to bother with it.”

“We’ll surprise him one of these days,” said John confidently.

“I certainly hope so,” exclaimed Grant.
