"Then when will we know it is time to adjust our masks?" Bazin persisted.
"When you see some one fall who has breathed it," the Major said.
"But suppose we breathe it first?"
"Then you won't need a mask," the Major replied, "You see, it's quite simple."
"Halt!" The sharp command, coming sternly but not too loud from somewhere in the adjacent mist, brought the party to a standstill in the open on the edge of the village. We remained notionless while the Major advanced upon command from the unseen. He rejoined us in several minutes with the remark that the challenge had come from one of his old men, and he only hoped the new companies taking over the line that night were as much on their jobs.
"Relief night always is trying," the Major explained. "Fritz always likes to jump the newcomers before they get the lay of the land. He tried it on the last relief, but we burnt him."
While talking the Major was leading the way through the first trench I had ever seen above the surface of the ground. The bottom of the trench was not only on a level with the surrounding terrain, but in some places it was even higher. Its walls, which rose almost to the height of a man's head, were made of large wicker woven cylinders filled with earth and stones.
Our guide informed us that the land which we were traversing was so low that any trench dug in the ground would simply be a ditch brimful of undrainable water, so that, inasmuch as this position was in the first line system, walls had been built on either side of the path to protect passers-by from shell fragments and indirect machine gun fire. We observed one large break where a shell had entered during the evening.
Farther on, this communicating passage, which was more corridor than trench, reached higher ground and descended into the earth. We reeled through its zig-zag course, staggering from one slanting corner to another.
The sides were fairly well retained by French wicker work, but every eighth or tenth duck board was missing, making it necessary for trench travellers to step knee-deep in cold water or to jump the gap. Correspondent Eyre, who was wearing shoes and puttees, abhorred these breaks.
