"Then for heaven's sake get the top off and let's get them out!"

It was then that the last cruel blow of Fate was dealt to the hapless Herbert. For after a brief period of feverish pulling, during which the company commander broke his nails and Percy fell over backwards, the trap-door remained in statu quo.

"What the devil's the matter with the beastly thing?" muttered the Captain, savagely. "It's your fool-trick, FitzPercy! Can't you open it?"

"My dear old boy," remarked the proud inventor vaguely, "it generally opens—'pon my soul, it does." He turned his torch on to the reluctant trench-board and examined it through his eyeglass. "By Jove! that's it, dear old son, there's the trouble. The dud shell has slipped forward and got wedged in the rafters. How doocid funny—what?"

"What is doocid funny, you blithering ass?"

"Why, if we'd gone on, dear old sport, the shell might have gone off. By Jove, that's good, that is!" Percy chuckled immoderately. "If we go on, the shell goes off!"

"You're the type of man who ought to be in a home," remarked his senior officer dispassionately. "Get a saw as soon as you can, and cut through the board. And if the bally shell goes off and kills you, it'll serve you right. You're a disease, FitzPercy, that's what you are. A walking microbe; an example of atavism; a throw-back to the tail period." Still muttering, his company commander passed out of sight, leaving the triumphant Percy completely unabashed and glowing with righteous success.

Now, in the trenches saws do not grow freely. You cannot wander round a corner and pick one up; in fact, a saw that will saw is an exceeding precious thing. Moreover, they are closely guarded by their rightful owners, who show great reluctance in parting with them. It therefore was not surprising that over an hour elapsed before a perspiring messenger returned with one and operations commenced. And during that hour Percy lived.

It is given to few to see their hopes and aspirations realised so beautifully and quickly; as in a dream he listened to the hideous cachinnations that floated up through the slabs of the trench-board. A continuous booming noise as of a bittern calling to its young was varied with heavy grunts and occasional blows of a heavy bludgeon on metal. And throughout it all there ran a delicate motif of crashing cups and tinkling tins.

"We have them, dear old soul," murmured Percy ecstatically to himself; "we have them simply wallowing in the mulligatawny!"
