Of course, as Kelly said, scratching is common in the best circles out there. The man who has to reach over his shoulder in an attempt to remove an irritation from that almost unattainable spot between the shoulder blades is not shunned or looked at askance, but serves only as a source of amusement to his companions. Underwear searching is a common, very common, form of pastime. Though you may have been a very dignified and sensitive soul, your sensitiveness gradually dulls until you care not a "hoot" who may see you sitting in a brilliant sunshine anxiously scanning your clothes; or rising at midnight from a much-troubled sleep and by dim candle light beginning the often well-rewarded inspection.

So far as the ordinary Tommy is concerned, he ignores not only his acquaintances but the world in general. There he sits in his bare pelt and performs a massacre which in numbers dwarfs almost to infinity the killings of the Armenians by the Turks. In the town of Vimy I one time passed a jocular, though profitable, hour at this occupation while I sat on the floor of the cellar of an old brewery with a Scotch padre on one side of me, and a Nova Scotia major on the other, all absorbed in the same intense search, while above our heads the shells every little while hit the fallen walls of our shelter. And through the thin-walled partition that separated us from our soldier-servants we heard propounded a most momentous question which showed us that they too were employing their time to advantage. The question was:—

"Say, Kelly, what the h—— will all the lice do for a living after the war?" And for once Kelly was floored.

Often dugouts are but shelters dug into the wall of a trench, a thin sheet-iron roof put on top, and two or three layers of sandbags on top of that. This gives protection against bullets, shrapnel, or bits of shell, but a straight hit from a medium-sized shell would go right through. And yet it is strange how seldom these are hit direct, considering their large numbers. This may in part account for one's feeling of relative security while in them, but this feeling is no doubt also partly due to our resemblance to the ostrich which hides its head to avoid danger. Be this as it may, many a good night's sleep have I passed in shelters such as this, with shells bursting within one hundred yards at frequent intervals during the night. During the month previous to the Battle of Arras my orderlies and I lived in an abode of this nature most of the time, only 500 yards from our front line trenches. Shells continually fell well within the hundred yard radius of it—as a matter of fact, shortly afterwards this dugout was completely blown in—yet no one worried in the least about it. This is not told as a strange experience, for all officers who have served at the front have often lived in the same surroundings. This experience is related only to illustrate one type of protective shelter.

Deep dugouts vary in depth anywhere from ten to forty or fifty feet in cases where the soldier has had to do all the digging, but in some cases where limestone quarrying has been extensively carried on there have often been found, ready to hand, caves, sixty to one hundred feet in depth, such as the famous Zivy cave, opposite Mt. St. Eloy. There are many of them about this region, some of which, as the one mentioned, are large enough to give shelter to 1000 men. Usually there is a circular airshaft in the center. This shaft in Zivy cave was the target for months for German gunners, as they had occupied this region, and knew it well. In fact the story is told that in this cave, or one of the others near about, 800 Germans were gassed and killed by the French when they retook this ground. How much truth is in the story it is difficult to say. But at any rate, all through the hard, cold winter of 1916-17 the Canadians who were holding this front found good protection and some warmth in this cave for many of their men, though at all times the air in it had a grayish tinge, as the ventilation was hardly up-to-date.

On one occasion at 11 p.m. Colonel J—— and the writer found Zivy cave as welcome a sight as ever struck the eye of man. Coming into the trenches, we stumbled into a heavy Hun artillery barrage. After a number of close shaves, in two of which we were buried in mud from the exploding shell, we were heavily dragging our feet through the thick mud of Guillermot trench when a shell struck full in the trench twenty feet in front of us, nearly bursting our ear drums. We pressed closely against the wall of the trench, awaiting the next. It came almost immediately, landing thirty feet behind us,—bracketing us.

"The next will get us, sir," I said.

"Not on your life, doctor," cheerfully replied Colonel J——. And he was right, for a few moments later we were stumbling into the entrance of Zivy cave, and that slimy, dark, four-foot opening was more welcome to us than would be today the spacious rotunda of the Savoy. I always admired the Colonel's cheerful confidence, but, as Kelly well said, "Confidence is a foine thing, but it raly has very little affict in stoppin' a Hun shell that's comin' yer way." This, the Colonel unfortunately found out in the Battle of Arras.

From one of these deep caves on the Vimy front previous to the battle of Easter Monday, tunnels miles in length, electric lighted, were built, leading to different headquarters, aid posts, ambulance depots, and to various points in No Man's Land. They were of inestimable service when the day of battle arrived. No doubt they will be among the show-places of France to encourage tourist traffic after the war.

The entrance to deep dugouts is usually only high enough to go through in a stooped position; and in this case the easiest way to enter them is to back down. After some practice one gets accustomed to this manner of progression, and it becomes easy—as if our bodies had reverted to the days of our cave-dwelling ancestry to accompany the turning back of civilization's clock. The two entrances preferably point away from the enemy lines, but in case of advance the enemy dugouts may be taken over in spite of the fact that their entrances seem to invite a shell to enter. And, rather strangely, shells rarely seem to make a straight hit on an entrance.
