"Bullets are nothin' at all," said he. "I wouldn't give you a snap of me fingers for them. Listen to them now, flyin' about and whinin' and whimperin' as if they wor lost, stolen or strayed, and wor lookin' for a billet to rest in. They differ greatly, do these bullets; but sure in time you'll larn them all by sound and be able to tell the humour each one of them is in. There's only one kind of bullet, boys, that you'll never hear; and that is the one which gives you such a pelt as to send you home to Ireland or to kingdom come. But," he continued, "what'll put the fear of God into your sowls, if it isn't there already, is the heavy metal which the Gerrys pitch across to us in exchange for ours. The first time I was up here I was beside a man whose teeth went chatterin' in a way that put me in fear of me life. Sure, didn't I think for a minute it was a Gerry machine-gun--may the divil cripple them!--startin' its bloody work at me ear. Now, there must be none of that in this trench. If you're afraid, don't show it; remimber always that the Gerrys are in just as great a fright, if not more so. Show your spunk. Stand fast or sit tight, and hope for the best. Above all, clinch your teeth." The bombardment of a trench by shells from guns in the rear of the enemy's lines, or by bombs thrown from mortars close at hand, is probably the greatest test of endurance that has ever been set to humanity. The devastating effect is terrific. At each explosion men may be blown to pieces or buried alive. Even the concussion often kills. A man might escape being hit by the flying projectiles and yet be blinded or made deaf or deprived of his speech by the shock. All feel as if their insides had collapsed. The suspense of waiting for the next shell or bomb, the uncertainty as to where it is going to fall, followed by the shake which the detonation gives the nervous system, are enough to wear out the most stout-hearted of soldiers. It is then that companionship and discipline tell. The men catch from one another the won't-appear-frightened determination, and the spirit of won't-give-in.
