"Captain's compliments, sir, and will you fire two rounds at G. 10 C. 5 4?"

Rapidly and without confusion the men did their appointed jobs; the great stalk slithered down the gun, the bomb—big as a football—filled with high explosive was fixed with a detonator, the lanyard to fire the charge was adjusted. Then every one cleared out of the emplacement, while the Sapper took his stand in the trench outside.

"Let her rip." The lanyard was pulled, and with a muffled crack the huge cannon-ball rose into the air, its steel stalk swaying behind it. Plainly visible, it reached its highest point, and still wobbling drunkenly went swishing down on to G. 10 C. 54—or thereabouts. A roar and a great column of black smoke rose from the German lines.

Almost before the report had died away, the gun was sponged out, and another inebriated monster departed on its mission. But the Sapper was already some way up the Haymarket. It was not his first view of a trench-mortar firing.

A vicious crack from a rifle now and then broke the stillness, and proclaimed that the sun was clearing away the morning mist, and that rest-time was nearly over; while the sudden rattle of a machine gun close by him, indulging in a little indirect fire at a well-known Hun gathering place a thousand yards or so behind their lines, disturbed a covey of partridges, which rose with an angry whirring of wings. Then came four of those unmistakable faint muffled bursts from high above his head, which betokened an aeroplane's morning gallop; and even as he automatically jerked his head skywards, with a swishing noise something buried itself in the earth not far away. It is well to remember that even Archibald's offspring obey the laws of gravity, and shells from an anti-aircraft gun, burst they never so high, descend sooner or later in the shape of jagged fragments—somewhere. And if the somewhere is your face, upturned to see the fun . . . !

The Sapper, with the remembrance fresh in his mind of a pal looking up in just such a way a week before, quickly presented the top of his tin hat to the skies, and all that might descend from them. There had been that same swishing all round them as they stood watching some close shooting at one of our own planes. He recalled the moment when he cried suddenly—"Jove! they've got him!" He had turned as he spoke to see the officer with him, slipping sideways, knees crumpling, body sagging. "Good God! old man, what is it?" The question was involuntary, for as he caught the limp figure—he knew.

The plane was all right: the German shells had not got it; but a piece of shrapnel, the size of a match-box, had passed through that officer's eye, and entered his brain. He had laid him on the firing-step, and covered his head—or what was left of it. . . .

He reached Pall Mall, to be once again confronted with a large white notice board. To the right were Boyaux 93 and 94—to the left, 91 and 90. Straight on to the front, 92 led to the firing line. With his ultimate destination Vesuvius crater and the rum jar in view, he turned to the right, and walked along the support trench. It was much the same as Piccadilly: only being one degree nearer the front, it was one degree more warlike. Boxes of bombs everywhere; stands for rifles on the firing-step, which held them rigidly when they fired rifle grenades; and every now and then a row of grey-painted rockets with a red top, which in case of emergency send up the coloured flares that give the S.O.S. signals to those behind. Also men: men who slept and ate and shaved and wrote and got bored. A poor show is trench warfare!

"Look out, sir. They've knocked it in just round the corner last night with trench mortars." A sergeant of the South Loamshires was speaking. "Having a go at Laburnum Cottage, I'm thinking."

"What, that sniper's post? Have you been using it?"
