"We have caught them at it!" said he. 'Julian is on top, and Jack is down below, shovelling dirt. Where are your revolvers?"

"Those fellows from the Flat have not come yet," said Jake, looking all around to make sure that the boys were alone. "Lead ahead, Bob, and remember that we are close at your heels."

Leaving his provisions behind him, Bob arose to his feet, stepped out of his place of concealment and advanced toward the pit.
