"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."
