For at the precise moment that an oil-can exploded with a thunderous crump twenty yards or so beyond the trench, there was a sudden noise of ripping canvas, an agonised shout, and the heavy crash of a body encountering china. Then--silence. The sap parties heard only the oil-can; Percy FitzPercy for a wonder was not brooding over his invention, and there was no one who knew that close beside them in an odoriferous underground abode the Brigadier-General lay completely stunned, with his head in a metal soup tureen and his rather extensive set of uppers in a disused tin hitherto devoted to that painstaking gentleman, Mr. Maconochie. Up to this point it will be willingly conceded, I think, by any one acquainted with trench etiquette that the unfortunate predicament of Herbert Firebrace, General and Great One, was only what he deserved. To depart so flagrantly from the spirit of the rules as to wander round front-line trenches alone and in the falling shades of night is asking for trouble; and if the matter had ended there I have no doubt--knowing the strict sense of justice which is one of the praiseworthy features of the house of Firebrace--I have no doubt that he would have sent for Percy FitzPercy and apologised handsomely for the inconvenience he had so unwittingly caused. But the matter did not end there; it only began. And the finale, reviewed dispassionately, undoubtedly gives one to think--one might even say think furiously. A quarter of an hour after the regrettable occurrence just described Percy stood chatting lightly and inconsequently with his company commander in the support line. At the moment he was expatiating on the merits of a new pipe of his own invention designed for use in No Man's Land on a dark night. Its exact beauties escape my memory; as far as I can remember one put the bowl in one's mouth and the tobacco in the stem and blew. It was an invention typical of Percy--utterly futile. He had just called the company commander "dear old soul" for the tenth time, and was explaining how no sparks or glowing ash could be seen if you made use of this patent atrocity, when a Lewis gun started rattling away in front. Half a dozen Verey lights shot up, there was a sudden brisk burst of firing, with the explosion of a number of bombs. "By Jove!" cried Percy, pipe and all else forgotten. "By Jove, dear old man--a raid--what? A Hun raid--now for the man-trap!" He departed at speed up the nearest boyau, leaving a trail of sparks behind him like a catherine-wheel that has been out in the rain; to be followed by his Captain, who had first taken the precaution of loading his automatic. The first man Percy met was the tooth-sucker, who was shaking with uncontrollable excitement. "There's a perisher fell in the 'ole, sir! Three of 'em come in, and we killed two an' the other fell in the 'ole."
