Jerrold was also wanting a supply, and he and Matt, leaving Carl and Ferral in charge of both air ships, started for the nearest house to find out where they could get the fuel of which they stood in need.
They found that gasoline was used for cooking, and for manufacturing gas for lighting, in the house where they inquired. The man who owned the place kindly offered to let the air ship owners have all they needed.
In less than an hour Matt and Jerrold were back and filling their gasoline tanks.
A little later Harris reached the scene. The sun was down and darkness was coming on.
"I couldn't get away any quicker," explained Harris. "I am leaving everything in good shape here, though. Harper is willing to go back to South Chicago without any requisition papers, but I thought it best to let him stay and take him across the lake at the same time we took Brady."
"I should think that would be better," agreed Matt.
"Harper is ready to turn states' evidence against the gang in the hope of getting a light sentence," went on Harris. "He claims to know where some more stolen property has been secreted, so I suppose there will be a few happy people in South Chicago if he proves that he knows what he's talking about."
"The law will deal lightly with Harper, I suppose," put in Jerrold, "if he does all that."
"I guess so, but the law will not let him off scot free. Harper will go to the 'pen,' but he won't get anywhere near the sentence that Brady will."
"How long will Brady go up for?"
