"Come on," urged Jimmy. "Let's settle with the _garcon_, and beat it. Where did he go to, anyhow? He was standing right over there a minute ago." Five pairs of eyes immediately busied themselves in an effort to locate the waiter. "He's in the kitchen, I guess. Don't see him. He'll show up in a minute." Leaning back in his chair, Roger continued idly to survey the few diners scattered about the café. His eyes rested amusedly upon a pair of elderly Frenchmen, who appeared to be conducting a vigorous argument. Their wagging heads, shrugging shoulders, and the almost continual play of their hands entertained him immensely. "Look at those two old grandpas over there near the door," he said to Bob, who was seated beside him. "I'll bet you most anything they're arguing about the war. They're not a bit huffy with each other; just dead in earnest." Bob's gaze obediently traveled toward the two ancients. It interrupted itself on the way, however, to take stock of three men who were just entering the café. "For the love of Mike!" His shrewd, black eyes widening with amazement, Bob leaped to his feet. "_Look_ who's here!" he exclaimed so loudly that his voice reached the entering trio. "Oh, you Twinkle Twins!" CHAPTER II MEETING COUSIN EMILE "Where, where?" Seated with his back to the door, Bob's gleeful announcement brought Jimmy also to his feet. By this time Bob had deserted his bunkies and was making straight for two young men in the uniform of the U. S. Aviation Corps, who were advancing to meet him. "Well, well, _well_! If it isn't old Bob and Blazes!" The blue-eyed, broadly-smiling youth who uttered this jubilant recognition, now had Bob's hand in a firm grip, and was shaking it vigorously. Standing beside him, his brother, an exact counterpart of himself, was engaged in greeting Jimmy with equal cordiality. "Let me in on this," commanded a laughing voice, as Roger joined the delighted quartet. "I believe I've seen the famous Twinkle Twins before to-day." "You'd better believe it," retorted Jack Twinkleton. "How are you, Rodge? You're looking all to the mustard." "Put her there! How's the good old scout?" Jerry Twinkleton now claimed Roger's attention. "Oh, we're simply fine. You can't lose us. It isn't being done, don't you know, with this gang." Roger's face glowed with friendliness as he greeted the illustrious twins. They were truly a welcome sight. "How long have you been over, and where do you go from here?" were Jimmy's quick questions. "We've been keeping an eye out and an ear open ever since we landed in France. Thought we'd see you or, maybe, hear news of you." "You're the great little scribes, you are," declared Bob. "We haven't had a line from you since just before we left Sterling." "When was that?" promptly asked Jack. "Oh, early in February. You fellows wrote that you were expecting most any day to go across."
