He had only just disappeared over the edge of the embankment when Kenneth, who had been straining his ears for sounds of movements below, heard a slight displacement of ballast on the line above him. Glancing up, he found himself looking straight at the barrel of a rifle, behind which was a head surmounted by a German helmet. For half a second he was paralysed with astonishment. Then a click galvanised him into activity. Realising that the rifle had missed fire, forgetting--like an idiot, as he afterwards confessed--that he had a revolver, he made a spring and with his left hand seized the muzzle a few feet above him. The German held fast; there was a momentary tug of war; then the German lost his footing on the slippery earth, fell suddenly to a sitting posture, and slid down the embankment helplessly, driving Kenneth under him into the shallow pool of water at the foot. Kenneth was a thought quicker than the German in recovering his wits. Wriggling sideways, he flung his arm over the man, spluttering out a mouthful of muddy water, and grappled him. For a few seconds they heaved and writhed like grampuses. Then Ginger, drawn by the splash, came running across the line, saw the struggling figures, sprang down the embankment, and dashed his fist in the German’s face. In another moment he had dragged the man out of the water and a foot or two up the embankment, and held him down until Kenneth had shaken himself and come to his side. "This beats cockfighting," he said. "Where did the beggar come from?" "Don’t know," said Kenneth. "We’ll see presently. I’m nearly choked with mud. We’ll have to use his braces too." When they had tied the man securely, they got up to investigate. What they discovered was a proof of the ingenuity which the Germans exhibit in all their undertakings. The landslide, a little to the right of the culvert, formed a sort of boss on the embankment. At the farther extremity of this, out of sight from the spot where Kenneth had stood, the German had forced his way up from a small chamber excavated in the base of the embankment, where he had a folding chair, a rug, a tin plate and mug, a supply of ammunition, and the basket which the visitor had carried. It was full of food. There were two or three inconspicuous openings for the admission of air, and, towards the British trenches, a small tube, and an arrangement by which the rifle could be clamped. Evidently the sniper took his sights in the daytime, and set the rifle in such a position in the tube that he could fire directly on the trenches with the certainty of having the correct aim. "Up to snuff, ain’t they, not half," said Ginger, with unwilling admiration. "But how did you come to be wallowing in that there puddle?" Kenneth explained. "My word! a lucky missfire," said Ginger. "Lucky indeed!" replied Kenneth. "And we can’t discover the cause of it; the rifle’s in the mud."
