We came to the edge of the marsh and halted for a moment. In front of us lay a dark pool, still as death and fringed with long grass and osier beds. A mournful breeze blew across the place, raising a plaintive croon, half of resignation and half of protest from the osiers and grasses as it passed. A little distance away the skeleton of a house stood up naked against the sky, the cold stars shining through its shattered rafters. "'Twas shelled like 'ell, that 'ouse," whispered Bill, leaning on his rifle and fixing his eyes on the ruined homestead. "The old man at our billet was tellin' some of us about it. The first shell went plunk through the roof and two children and the mother were bowled over."

"Killed?"

"I should say so," mumbled my mate; then, "There's one comin' our way." Out over the line of trenches it sped towards us, whistling in its flight, and we could almost trace by its sound the line it followed in the air. It fell on the pool in front, bursting as it touched the water, and we were drenched with spray.

"'Urt?" asked Bill.

"Just wet a little."

"A little!" he exclaimed, gazing at the spot where the shell exploded. "I'm soaked to the pelt. Damn it, 'twill frighten the ducks."

"Have you ever shot any living thing?" I asked my mate as I tried to wipe the water from my face with the sleeve of my coat.

"Me! Never in my nat'ral," Bill explained. "But when I saw them ducks this mornin' I thought I'd like to pot one o' em."

"Its impossible to see anything now," I told him. "And there's another shell!"

It yelled over our heads and burst near our billet on the soft mossy field which we had just crossed. Another followed, flew over the roof of the dwelling and shattered the wall of an outhouse to pieces. Somewhere near a dog barked loudly when the echo of the explosion died away, and a steed neighed in the horse-lines on the other side of the marsh. Then, drowning all other noises, an English gun spoke and a projectile wheeled through the air and towards the enemy. The monster of the thicket awake from a twelve hour sleep was speaking. Bill and I knew where he was hidden; the great gun that the enemy had been trying to locate for months and which he never discovered. He, the monster of the thicket, was working havoc in the foeman's trenches, and day after day great searching shells sped up past our billet warm from the German guns, but always they went far wide of their mark. Never could they discover the locality of the terrifying ninety-pounder, he who slept all day in his thicket home, awoke at midnight and worked until dawn.
