After alighting from the cars, their first mission was to seek a restaurant, and from that point they soon reached the post office, only to be again disappointed. At the telegraph office they had the same bad luck. "I wonder where father is?" said Alfred. "I suppose we shall have to go, whether we want to or not," suggested Ralph. "Let us inquire at the transportation office." At the main office they soon learned that the troops from England were occupying every coach, motor wagon and bus that was in sight, and that there was no encouragement in that direction. But an idea occurred to Alfred. "We belong to the army, don't we?" he said. "Suppose we apply as soldiers, and tell them we must get to Paris at once." They reached the main office of the Army transportation service, and boldly made their way to the room indicated by an attendant. In a few moments they were ushered in, and saw at least a score or more soldiers and officers in the room, at one end of which sat a white-haired officer, and several other officers, issuing orders. "Your business?" said an officer, approaching them. "We have been with the Belgians, and have just come from Antwerp. We are Americans, and are trying to reach Paris, and we wanted to know if we couldn't go on one of the trains?" explained Alfred. The officer shook his head. "I am sorry to say that we cannot provide for any one unless connected with the army," he said. "But we are connected with the army," said Ralph. "We were messengers, and have had a lively time, too." "Yes, and we expect to join the flying corps, but father expects me in Paris," said Alfred. The officer smiled, and pondered a moment. Then, motioning to them, he passed out of the room, the boys following. They crossed the hall, and entered a narrow room. "Lieutenant," he said, "issue a permit for these boys to ride on any available train to Paris." The boys expressed their thanks to the officer, and, after giving their names and home addresses, they received a card, which stated that the Army transport service permitted them to ride on any train where there was available room, at the discretion of the officer in charge of the train. "I should advise you to see the officer at the station in the morning, and get him to assign you to a train number, as the quickest way," said the clerk, as he handed them the permit. "Nothing like determination," said Ralph. "It is bound to pull you through." It was too late for them to return to the aviation field that evening, so after considerable search, they finally found a room, and after discussing the events of the day fell asleep, and awoke long after the sun had risen. "We've got to do some hustling," said Ralph. "We ought to see Tom this morning and tell him of our good luck." They partook of a hasty breakfast, and were at the station in order to get an assignment. But this was not an easy matter. They waited for nearly two hours before they were able to reach the proper official.
