"Wait!" shouted Fenton. "Don't go off and leave us in this plight! We'll starve to death if you do!"
"What about those plans?" demanded Will.
"I'll help you find the plans!" screamed Cameron. "I'll see that you get the plans; if you get us out of this scrape!"
"Keep still!" commanded Fenton.
"I refuse to keep still!" declared Cameron. "I'm not going to be left here to be devoured by insects. Tell me the truth about the plans," he went on, "what do you want of them?"
"We want to introduce the plans in evidence in the criminal court at Chicago," replied Will.
"And that will betray our secret," commented Fenton fiercely. "Those plans are worth millions of dollars to us! They represent the only perfect mining machine ever invented."
"We don't care anything about your mining machine," Will answered.
"Have you noticed anything peculiar about the plans?" Frank asked.
"Nothing except that they are dirty!" was the reply.
