"Say, Howe!" Tom Randolph, who lay next him, was pressing his hand. "I think I heard a shell go over." As he spoke there came a shrill, loudening whine, and an explosion that shook the barn. A little dirt fell down on Martin's face. "Say, fellers, that was damn near," came a voice from the floor of the barn. "We'd better go over to the quarry." "Oh, hell, I was sound asleep!" A vicious shriek overhead and a shaking snort of explosion. "Gee, that was in the house behind us...." "I smell gas." "Ye damn fool, it's carbide." "One of the Frenchmen said it was gas." "All right, fellers, put on your masks." Outside there was a sickly rough smell in the air that mingled strangely with the perfume of the cool night, musical with the gurgling of the stream through the little valley where their barn was. They crouched in a quarry by the roadside, a straggling, half-naked group, and watched the flashes in the sky northward, where artillery along the lines kept up a continuous hammering drumbeat. Over their heads shells shrieked at two-minute intervals, to explode with a rattling ripping sound in the village on the other side of the valley. "Damn foolishness," muttered Tom Randolph in his rich Southern voice. "Why don't those damn gunners go to sleep and let us go to sleep?... They must be tired like we are." A shell burst in a house on the crest of the hill opposite, so that they saw the flash against the starry night sky. In the silence that followed, the moaning shriek of a man came faintly across the valley. * * * * * Martin sat on the steps of the dugout, looking up the shattered shaft of a tree, from the top of which a few ribbons of bark fluttered against the mauve evening sky. In the quiet he could hear the voices of men chatting in the dark below him, and a sound of someone whistling as he worked. Now and then, like some ungainly bird, a high calibre shell trundled through the air overhead; after its noise had completely died away would come the thud of the explosion. It was like battledore and shuttlecock, these huge masses whirling through the evening far above his head, now from one side, now from the other. It gave him somehow a cosy feeling of safety, as if he were under some sort of a bridge over which freight-cars were shunted madly to and fro. The doctor in charge of the post came up and sat beside Martin. He was a small brown man with slim black moustaches that curved like the horns of a long-horn steer. He stood on tip-toe on the top step and peered about in every direction with an air of ownership, then sat down again and began talking briskly. "We are exactly four hundred and five mètres from the Boche.... Five hundred mètres from here they are drinking beer and saying, 'Hoch der Kaiser.'" "About as much as we're saying 'Vive la République', I should say." "Who knows? But it is quiet here, isn't it? It's quieter here than in Paris." "The sky is very beautiful to-night."
