"We'll amble out that way to-morrow and learn how to break pigeons of the loafing habit." Billy had once had a loft full of pouters in Bangor, that, he claimed, ate their breakfast in bed! "We'll shake Schneider and start early." Schneider had been detailed by Roque to keep an eye on the boys, but Henri felt sure that this firebrand would not be interested in pigeons, save in a potpie, so he suggested the "shaking" process. Trained in the sense of location by their aviation experience, the boys proceeded without difficulty to the sparsely settled neighborhood of the red-roof, which they found to be in the center of a neglected garden, overgrown with weeds. "Don't see any pigeon loft yet?" Having been a fancier himself, Billy knew how the birds were housed. "You might also say that you don't see any pigeons," added Henri. "We've surely run by the station." "Not on a little excursion like this," maintained Billy. "This is no ghost story." With the words he led the way up the long gravel walk extending from the rusty iron gate to the front of the house. "What will we tell them?" he asked, reaching for the brass knocker on the dingy door of the dwelling. "How will it do to say we are from the gas office?" "A fool answer fits a fool's errand," agreed Billy as he gave the knocker a sounding rap. The pounding awakened no sign of life. "Come on, Billy," urged Henri, "let's go. It's all a crazy move, anyhow, and it was just because we were idle that we ever thought of it." "I'm going to try the back door," insisted Billy, "and then we'll quit." There they got a response, probably after an advance inspection. The door was partly opened by a bent, palsy-shaken old man, who in quavering, high-pitched voice inquired their business. The question was in French, and Henri responded: "We just came out to look at your pigeons, and"--the age fell from the figure in the doorway in the twinkling of an eye, two long arms shot out, and in steely grip the astonished visitors were jerked inside, the door closing with a slam behind them. "What's the matter with you?" gasped Billy, whose collar had been given a tight twist by quick-grasping, sinewy fingers. Another violent wrench of the neck-joint was the rude form of answer. Billy's fighting blood took fire, and he launched a kick at his tormentor which sent the latter spinning, doubled-up, clear across the entrance hall. The jarred one, recovering his breath, leaped like a panther at the Bangor boy, but Henri gave him the tripping foot, and he measured his length on the dusty floor. The boys were making a break for the door, when a new figure blocked the way, suddenly emerging from a room nearby--a resolute fellow, with a cold, gray stare, backing up a steadily leveled revolver. "Been stirring up the monkeys, have you, Fred?" The fallen man raised himself on his elbow and made the air blue for a moment with his wrathful expressions.
