Snapper promptly produced his instrument and mouth-organed the opening bars, and the Towers joined in and sang the tune with vociferous "la-la-las." When they had finished, two or three of the Frenchmen, after a quick word together struck up "God Save the King." Instantly the others commenced to pick it up, but before they had sung three words 'Enery Irving, in tones of horror, demanded "The Mar-shall-aise again; quick, you idiot!" from Snapper, and himself swung off into a falsetto rendering of "Three Blind Mice." In a moment the Towers had in full swing their medley caricature of the French march singing, under which "God Save the King" was very completely drowned. "What the devil d'you mean? Are you all mad?" demanded a wrathful subaltern, plunging round the traverse to where Snapper mouth-organed the "Marseillaise," 'Enery Irving lustily intoned his anthem of the Blind Mice, and Corporal Flannigan passed from the deep lowing of a cow to the clarion calls of the farmyard rooster. "Beg pardon, sir," said 'Enery Irving with lofty dignity, "but if I 'adn't started this row the 'ole trenchful o' Frenchies would 'ave been 'owling our 'Gawd Save.' I saw that 'ud be a clean give-away, an' the order bein' to act so as to deceive----" "Quite right," said the officer, "and a smart idea of yours to block it. But who was the crazy ass who started it by singing the 'Marseillaise'?" On this point, however, 'Enery was discreetly silent. Before the French had cleared the trench the Germans opened a leisurely bombardment with a trench mortar. This delayed the proceeding somewhat, because it was reckoned wiser to halt the men and clear them from the crowded trench into the dug-outs. "With the double company of French and British, there was rather a tight squeeze in the shelters, wonderfully commodious as they were. "Now this," said Corporal Flannigan, "is what I call something like a dug-out." He looked appreciatively round the square, smooth-walled chamber and up the steps to the small opening which gave admittance to it. "Good dodge, too, this sinking it deep underground. Even if a bomb dropped in the trench just outside, and pieces blew in the door, they'd only go over our heads. Something like, this is." "I wonder," said another reflectively, "why we don't have dug-outs like this in our line?" He spoke in a slightly aggrieved tone, as if dugouts were things that were issued from the Quarter-Master's store, and therefore a legitimate cause for free complaint. He and his fellows would certainly have felt a good deal more aggrieved, however, if they had been set the labor of making such dug-outs.
