A few minutes later another couple of men crawled along and huddled down beside Pug. “Crump blew the trench in on some o’ us along there,” said one. “Buried a couple an’ sent Jim an’ me flyin’. Couldn’t get the other two out neither. Could we, Jim?” Jim only shook his head. He had a slight cut over one eye, from which at intervals he mechanically wiped the blood with a shaking hand. “Trench along there is a fair wreck,” went on the other, then stopped and held his breath at the harsh rising roar that told of another heavy shell approaching. The four men flattened themselves to earth until the shell struck with a heavy jarring THUMP that set the ground quivering. “Dud,” said two or three of them simultaneously, and “Thank God,” said Kentucky, “the burst would have sure got us that time.” “Wot’s that they’re shoutin’ along there?” said Pug anxiously. “Strewth!” and he gasped a deep breath and grabbed hurriedly for the bag slung at his side. “Gas ... ’Helmets on,’ they’re shoutin’.” Through the acrid odors of the explosives’ fumes Kentucky caught a faint whiff of a heavy, sickly, sweet scent. Instantly he stopped breathing and, with the other three, hastily wrenched out the flannel helmet slung in its special bag by his side, pulled it over his head, and, clutching its folds tightly round his throat with one hand, tore open his jacket collar, stuffed the lower edge of the flannel inside his jacket and buttoned it up again. All four finished the oft-drilled operation at the same moment, lay perfectly quiet, inhaling the pungent odor of the impregnated flannel, and peering upward through the eye-pieces for any visible sign of the gas. They waited there without moving for another five minutes, with the shells still pounding and crashing and hammering down all round them. Pug leaned over and put his muffled mouth close to Kentucky’s ear: “They got a dead set on us here,” he shouted. “Looks like our number was up this time, an’s if they meant to blow this trench to blazes.” Kentucky nodded his cowled head. It did look as if the German gunners were determined to completely obliterate that portion of the trench, but meantime--it was very ridiculous, of course, but there it was--his mind was completely filled with vague gropings in his memory to recall what perfume it was that the scent of the gas reminded him of. He puzzled over it, recalling scent after scent in vain, sure that he was perfectly familiar with it, and yet unable to place it. It was most intensely and stupidly irritating.
