"In the old envelope, back of the mirror," replied Dick in the same low voice. Then, in louder tones, he added: "We'd be glad of some help. It's hard work."
"Sam, and Bill, don't you want to get busy?" went on the young engineer.
"Sure!" said Sam. In fact, he and his companion seemed anxious to get the three boys away from the vicinity. The men helped spread and fasten down the canvas strips, and as Dick got in the car to drive it forward, he saw Mr. Cameron looking over the legal papers that proved how he had been deceived.
"By Jove, Hamilton!" he exclaimed, "you were right. They have put up a great game on me."
"Then will you turn them down?"
"I certainly will. I'm on your side from now on. I didn't understand it. These papers make it plain." He and Dick could talk without being regarded suspiciously, since the two men were working with Paul and Innis, spreading the strips of canvas.
Once or twice the two men looked at the car, as though wondering why Mr. Cameron was riding in it. He guessed their thoughts, and, putting back the papers, said to Dick:
"You may not need these, with my testimony. Still, keep them safe. Now I'd better leave you. Those fellows are paid to watch me as a cat does a mouse. How can I get away and reach 'Frisco?"
"We'll take you," said Dick, promptly. "We've accommodations for four in this car. Can you manage to escape?"
"Yes, and it had better be to-night. There is a gully about a mile from here, near a dried water hole. You'll get to it if you keep straight on. Can you wait for me there?"
