When they had gone nearly one hundred miles, Dave saw that the gasoline supply was running low. Luckily they were near a little town. They made a descent on a river, much to the delight and wonder of the whole place, bought a new supply, and resumed their flight. It was after ten o'clock in the evening when the welcome lights of Anseton came into view. Dave did not look around for some hiding place on the outskirts on this occasion. He startled a drowsy policeman by landing in the middle of some vacant lots on his beat. A brief explanation was made to the officer, and a man hired to watch the Drifter until they returned. Then Dave and Hiram hurried to the hotel in Anseton where Mr. Price made his headquarters. The revenue officer was found. He listened to the story of the two young aviators in amazement and admiration. Then he reported results of his own efforts. Ridgely was under arrest, two of his accomplices were being then pursued by his assistants, and the smuggling combination was all broken up. "The clews you have given us were fine ones, Dashaway," said the official gratefully. "You have done the government a vast service, I can tell you." Mr. Price insisted on the boys taking a needed rest. He sent one of his men to guard the Drifter, and, after a famous meal, made his guests agree to sleep in a comfortable bed for the first time in nearly a week. It was just after they had entered their room that Dave made the remark. "You know we had better see if those friends of the Dawsons have found the Monarch II and made away with it, Hiram." "Well, I can tell you that they haven't," replied Hiram, with a confident chuckle. "How can you know that?" "Why, Dave, when I was shut in with the machine in that basin, I took it apart. You know it was made to do that, so it could be shipped readily. Well, I'll bet you I hid those parts in places in that basin where nobody can locate them but myself." "Good for you!" commended Dave heartily. "I think the Interstate people will have something pleasant to say to you when they know all the wonders you've done in chasing their stolen airship." It was the brightest day in the year, it seemed to the two young aviators, as they reached Columbus by train, and started at once for Mr. King's hangar. Old Grimshaw had met them at the depot. He was full of friendly chatter, seemed to be chuckling over some secret surprise he had in store for them, and rushed them towards the headquarters of the Aegis. "Yes, Mr. King is back," he advised the boys. "Did he find Mr. Dale?" inquired Dave anxiously. "He'll tell you." Dave and Hiram had much to relate. Two boys probably never received a more pleasant welcome than they, when with the Drifter they reported to the manager of the Interstate Aeroplane Company.
