"You might come over and see us," added Bill, somewhat awkwardly. "We can't offer you much in the way of entertainment, but we'll do our best." "Thanks," answered Dick. "We may come, but we're going to pull out of this to-morrow, I hope. As soon as we can get out of this sand bog we'll travel." "We struck one of those places," volunteered Sam, "and we had quite a time of it. Well, so-long," and he and his companion seemed to hover around Mr. Cameron as though they were afraid he would let out something of the secret that had already been told, had they only known it. Good-nights were said, and the three disappeared in the darkness. The chums stood for a moment silent about their dying camp fire. "Well, what do you know about that?" asked Paul. "It's a queer go," assented Innis. "Those men are just like guards," said Dick. "Uncle Ezra, or his agents, must be afraid Mr. Cameron will go back on his promise." "If it was a promise given under misrepresentation then he is released from it--that holds in law," said Paul. "I believe it does," agreed our hero. "I hope I get a chance to speak to him to-morrow. The idea of hiding him away out in this desert to prevent him from going to court. It's outrageous." "Do you think he'll testify for Mr. Wardell if you show him the facts?" asked Paul. "I sure do. Well, let's turn in. To-morrow will be another day. There's a lot of hard work ahead of us." They were up early the next morning, the night having passed without incident, though Grit growled several times as though intruders--human or otherwise--were about the camp. But he gave no decided alarm, and the boys did not pay much attention. Soon after breakfast they resumed work on getting the auto out of the clinging sand, by using the canvas strips. While they were engaged on this, Mr. Cameron and his two guards came up. "We came to see if we could help you any," he said, with a wink. "At the same time I'd like to get a look at your car." He passed close to Dick, and found a chance to whisper: "Where are the papers?" "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.
