"That is the place where I live," said the elder of the two men, as he pointed to a low cottage on the side of a hill, "and Raoul here lives below the turn. We must approach the house cautiously, for we know spies to be in this part of the country." "I will go ahead," said Raoul. "Follow and go up to your house through the orchard." They tarried by the roadside until the signal appeared. Upon reaching the house they were greeted by Felix's wife, for that was the name Raoul bestowed on his friend. A good meal was soon spread before them, and in the meantime the lieutenant was plied with questions, as the people in that section had no opportunities for learning what was really taking place in the outside world. Finally the lieutenant asked: "Do you know of any place where we could get some petrol?" The men mused for a while, and shook their heads. "You know," Felix said, "everything around here is controlled by the Germans, and petrol is one of the things that is kept strictly under guard." "Do you know the place where they store it?" inquired the lieutenant. "Yes, but it would be dangerous to attempt to get any of it," said Raoul. "I have a plan," said Felix, "but we cannot do anything before night. I know every step of the way to the station, and will take you there this evening." "Good!" said the lieutenant. "In the meantime, give me a diagram of the station, and the roads leading to it. That will help me to become familiar with the surroundings." For the next hour the lieutenant was busily engaged in learning all about the country, and where the stores and ammunition were kept. "I think we might as well have some of that petrol," said the lieutenant with a smile, as he looked at the boys, who nodded their approval, as they were keen to participate in the plans which the lieutenant had formed. That night, after ten o'clock, they appeared at their place of concealment, for it was thought wise to keep away from the house in the event any of the prying neighbors should happen in. Together they cautiously found their way to the railway and walked along the track until the first switch was reached. While waiting there so that Felix could point out the different objects, Ralph drew the lever, and set it so the first train would take the switch. The lieutenant saw it and nodded approvingly. Ahead a few hundred feet was a low building, which was reached by the track which led from the switch. "The guards are stationed at that shed across the track, and sometimes they come over," said Felix. "But is the building open?" asked the lieutenant. "There are no doors; only open arches. The tanks can be loaded and unloaded from the tracks," was the answer. They were carrying three vessels, such as are usually employed for transporting petrol in small quantities, and nearing the shed the lieutenant said: "Remain here and await my orders. I will go ahead and investigate."
