Placing a brick under one of the wheels, he unharnessed his horses and led them down the hill. Kenneth and Ginger were carrying a box between them to the communication trench running downwards from the crest when a shell came whizzing over from the German side and exploded near the lorry they had just left, bespattering them with earth, felling one or two of their comrades, and sending the rest scampering into the trench. The shock of the explosion caused Kenneth to drop his end of the box: both he and Ginger were dazed for a few seconds. When they looked round, they were aghast to see the lorry moving backward down the hill. Only half its load had been removed, and though its motion was at present slow, it would gather speed and, unless it could be checked, would crash into the second lorry to which the driver was now yoking his horses. For a moment they were paralysed by realisation of the frightful danger. Men, horses, stores would all be hurled and crushed in hideous wreck. The heavy vehicle was already rolling on more quickly when with mutual decision they left the box and sprinted after it. The case was desperate. Neither of them had any idea how the catastrophe could be averted. It would scarcely be possible to loose the skid and throw it into position while the lorry was running, faster every moment. More fleet of foot than Ginger, Kenneth rushed ahead, overtook the lorry, and, a thought striking him, seized the pole, and exerting all the force of which he was capable while running at speed, twisted it to the left. The lorry swerved, appeared to hesitate, then ran into a shallow ditch at the side of the road and turned over. The pole, striking against a tree, snapped off, flinging Kenneth to the ground. "Whew!" gasped Ginger, running down. "That was a near thing." "Twenty yards," said Kenneth, rising and rubbing his elbow. "George! that was a near ’un!" panted the driver, who had hastened up. His face was very pale. "I owe you one, mate. Nothing else would have saved us. Hope you ain’t hurt." "Nothing to speak of. The lorry has come off the worst." "George! you’re right! It’s what you may call snookered. Done for, that’s what it is. We’ll have to shove it out of the way before I can bring my horses up, and leave it. What you say, Bill?" "Can’t do nothing with it," said the driver of the second lorry. "Take my tip, and put the skid on when you get yourn up, mate. George! it give me a fright and no mistake." They drove the second lorry to the summit, leaving Kenneth and Ginger to carry up the spilled load. "The lorry isn’t so badly damaged as he thinks," said Kenneth. "The brake is bent, and a good deal of wood is chipped off, but the thing will run all right." He so informed the driver when he met him. "All the same, you don’t catch me driving it back to-night," said the man. "It’s nearly dark, the road’s bad enough when you’re too complay, as the Frenchies say. I’ll leave it to the morning at any rate."
