"Wouldn't that be fine?" replied Ralph. The sight seemed to be an inspiration to the boys. Our story will tell how the idea so impressed itself on their minds that they almost felt it a duty to join a flying corps. That, however, seemed to be an impossibility. They had passed through Belgium, participated in the first battles of the war, had been captured, and escaped from the Germans, and had now reached Antwerp, with the retreating Belgian army, where Ralph had hoped to meet his father, whom they had left in Germany almost four weeks prior to that time. As the father had not arrived, owing to the embargo which had been placed on all travelers from Germany to the warring countries, the boys found themselves stranded in a strange city. Fortunately, their connection with the army, and the fact that they had rendered Belgium some service, made it possible for them to get food and lodging. "We have forgotten one thing," said Ralph. "What is that?" inquired Alfred. "Why, we never went to the Post Office," replied Ralph. At the General Post Office they received a letter from Alfred's father, only to learn that he had been detained, as was the case with thousands of Americans, and that it would be impossible for him to reach Antwerp. Instead, he would be permitted to go through Switzerland, and from that country reach Paris where he hoped to meet them. "But we have no money now, what shall we do?" asked Alfred. "That's what worries me," answered Ralph. "Father supposes that Pierre is still with us, and that we are supplied with money." Three days after receiving the letter the boys heard the first definite news of the great movement of German troops designed to attack the forts. If they surrounded the city, and besieged it, the chances of reaching Paris would be small, indeed. "Something must be done, and that today," said Ralph. "I am going to leave if I have to walk." "Where to?" asked Alfred. Ralph smiled, as he said: "We might walk to Holland." Alfred almost shouted for joy, as he exclaimed: "That's a good idea. We have about ten francs left; that ought to take us through." A map was consulted. "Why, yes," said Alfred, "we can go north to Eeckeren, and from that place to Capellen, close to the frontier. It's only twelve miles." After this decision they again visited the Post Office, and immediately crossed through the city with a view of striking the main highway leading to Holland. Reaching the outskirts of the city, they were surprised to see great masses of Belgian troops encamped close to the forts, which guarded the highway. They soon learned that a strong German column had reached Brasscheat, three miles from Eeckeren. They looked at each other in amazement. "Well, this beats everything," said Alfred, with a shade of bitterness. "The Germans seem to be in our way whichever direction we turn. We'll have to take another route."
