Look through the periscope at the country in front. Not a sign of life in the torn-up crusted earth; not a movement between the two long lines of wire. A few poppies here and there, and at one point a motionless grey-green lump close to the farther wire. Impossible to tell exactly what it is from the periscope--the range is too far. But, in No Man's Land, such strange grey--and khaki--lumps may often be seen. The night, a wiring party, perhaps a little raid or an officer's patrol, and--discovery. You cannot always get your dead back to the trench, and the laws that govern No Man's Land savour of the primitive. . . . The Sapper watched the phlegmatic bellows-heaver for a few moments curiously. His stoical indifference to any one or anything save the job in hand, the wonderful accuracy with which he spat from time to time, the appalling fumes from his short clay pipe, all tended to make of him an interesting study. Supremely apathetic to friend or foe, Generals or Huns, he did his shift without comment and, as far as could be seen, without thought. "Where are you putting the earth?" asked the Sapper after watching for a while. "Round corner, in a 'ole." The speaker pointed with his pipe, and the subject dropped. The officer turned away smiling slightly, and decided on the inspection of the rum jar. The answer was clear and succinct, even if not couched in the language of the old army discipline. He inspected the hole, and, finding it was at the back of the trench, in a crater that was formed nightly by German _minenwerfer_, and that more earth there not only would not block the trench but, _mirabile dicta_, would be an actual advantage, he passed on and shortly came to a passage leading out of the front of the trench. The passage was labelled Sap No. 130, and presented exactly the same appearance as the boyaux which ran out of the support line to the front trench. Only when one got into it did the difference become apparent, for whereas the boyaux had continued until finally opening into a new trench, the sap was a cul-de-sac, and finished abruptly in a little covered-in recess built into a miniature mountain of newly-thrown-up earth. And this great, tumbled mass of soil was the near lip of Vesuvius crater--blown up half way between the two front lines. Over the top of the mountain there was no passage. A man standing or crawling there in daytime would have been in full view of German snipers at a range of forty yards; while had he accomplished it in safety, he would have slithered down the farther side into a great cavity shaped like an egg-cup, at the bottom of which a pool of dirty, stagnant water was slowly forming. Moreover, if we imagine the man continuing his journey and climbing up the other side, he would run the gauntlet of the English snipers as he topped the farther lip, before reaching the German sap which ran out in just such a similar cul-de-sac to the one already described.
