"Look stupid," said Pierre promptly. "He didn't see us, and he'd never dream we had seen him; but, by our blessed Saint Jeanne, this is where I get even with the Germans! Let's find Jim and Uncle Sam." Reveille was just sounding as they entered the camp and presented themselves at the door of Uncle Sam's tent. During the weeks that had elapsed since their arrival in France, Jim and Uncle Sam had acquired a fair working knowledge of the language, and, though it still remained a queer mixture of French and English, they and the children managed to understand each other very well. "Bonjour, kids!" cried Uncle Sam in astonishment, when he saw the two children at the tent door. "What on earth are you doing here? Don't you know visitors are not expected in camp at this hour?" "Sh--sh!" said Pierre, laying his finger on his lips. "Nobody must see us! We have important news!" Uncle Sam sat up in bed. "Why, I believe you have," he said, looking attentively at their pale faces. "Just wait a minute while I get my clothes on. Here, you--Jim," he added, poking a recumbent figure in the adjoining cot. "Roll out! It's reveille!" Jim sat up at once and rubbed his eyes, and, after a hurried consultation, the two men turned the two children with their faces to the wall in one corner of the tent, while they made a hasty toilet in the other. "Now, then, out with it," said Uncle Sam a few moments later. "Que vooly-voo? What's up?" Jim sat down beside him on the edge of the cot, and the two men listened in amazement to the story the two children had to tell. When they had finished, Uncle Sam wasted no words. "Come with me to the Captain tooty sweet," he said. And Jim added, as he patted the Twins tenderly on the head, "By George, mes enfants, you ought to get the war cross for this day's work." A few moments more, and the children and Uncle Sam were ushered by an orderly into the presence of the Captain, who was just in the act of shaving. Uncle Sam's message to him had been so imperative that they were admitted at once to his presence, even though his face was covered with lather and he was likely to fill his mouth with soap if he opened it. Uncle Sam saluted, and the Twins, wishing to be as polite as possible, saluted too. The Captain returned the salute, and went on shaving as he listened to their story, grunting now and then emphatically instead of speaking, on account of the soap. When Pierre came to what the soldier had said under the shed, he was so much interested that he cut his chin. "So that's their program, is it?" he sputtered, soap and all, mopping his chin. "But how on earth did you happen to be in such a place as that at such an hour in the morning?" Pierre explained about the rabbits and the cress, and Uncle Sam added: "They're from Fontanelle. Their father is a soldier wounded at the Marne, and they lived under fire in Rheims for eight months before coming here. They're some kids, believe me! They know what war is."
