CHAPTER VII BOUND FOR VERDUN For three days more the boys wandered about Paris,—three days of the most fearful suspense; and then began the battle of the Marne. Every airplane in and about Paris was at the front, on the line somewhere, and the boys were deprived of the opportunity to see the new friend they had made at the Bois de Boulogne station. They were so sure of being able to go to Verdun that Albert wrote to his father of their plans, in the hope that he would consider it wise to leave Switzerland for that point, where they might meet. The Germans had been defeated; Paris was safe, the French line having held firmly all the way to Verdun. The determination to go there was firmly fixed in their minds, but they could see no way to accomplish the purpose. A visit to Tom at the hospital only resulted in their being told that the lieutenant was in the field, no one knew where. "I have an idea," said Ralph, as they emerged from their room one morning. "What is it?" asked Alfred. "We might get attached to the Red Cross some[Pg 85] way, and that would be sure to take us to the front," replied Ralph. [Pg 85] "That would be just as hard as to get in with the flying people," answered Alfred. "That may be so, too, but I can't see any other way." They again called at the Continental Hotel in the hope that there might be some further news. To their surprise they found a letter from Alfred's father with a check for their personal expenses. While reading the letter they overheard a conversation which gave them the solution, as they thought, of their difficulties. "No," said a voice, "they will not ticket us to any point near the firing line, but we might go to St. Dizier, and from there work our way north." "Good idea; let's book at once," said the second voice. "Come on," said Alfred. "That's the right tip. Let's find out where St. Dizier is." The clerk informed them: "It is about a hundred and sixty miles east of Paris." "Then it can't be far from Verdun," remarked Alfred.
