As for the matter of keeping out of sight, there was a good deal to be said on both sides. Although Tommy was impatient with his prudent enemy and sang songs, twitting him about always keeping under cover, he did not usually forget, in the daytime at least, to make his own observations of the German line with caution. Telescopic sights have made the business of sniping an exact science. They magnify the object aimed at many diameters, and if it remains in view long enough to permit the pulling of a trigger, the chances of a hit are almost one hundred per cent.

II. "THE BUTT-NOTCHER"

Snipers have a roving commission. They move from one part of the line to another, sometimes firing from carefully concealed loopholes in the parapet, sometimes from snipers' nests in trees or hedges. Often they creep out into the tall grass of No-Man's-Land. There, with a plentiful supply of food and ammunition, they remain for a day or two at a time, lying in wait for victims. It was a cold-blooded business, and hateful to some of the men. With others, the passion for it grew. They kept tally of their victims by cutting notches on the butts of their rifles.

I well remember the pleasant June day when I first met a "butt-notcher." I was going for water, to an old farmhouse about half a mile from our sector of trench. It was a day of bright sunshine. Poppies and buttercups had taken root in the banks of earth heaped up on either side of the communication trench. They were nodding their heads as gayly in the breeze as of old did Wordsworth's daffodils in the quiet countryside at Rydal Mount. It was a joy to see them there, reminding one that God was still in his heaven, whatever might be wrong with the world. It was a joy to be alive, a joy which one could share unselfishly with friend and enemy alike. The colossal stupidity of war was never more apparent to me than upon that day. I hated my job, and if I hated any man, it was the one who had invented the murderous little weapon known as a machine gun.

I longed to get out on top of the ground. I wanted to lie at full length in the grass; for it was June, and Nature has a way of making one feel the call of June, even from the bottom of a communication trench seven feet deep. Flowers and grass peep down at one, and white clouds sail placidly across

"The strip of blue we prisoners call the sky."

I felt that I must see all of the sky and see it at once. Therefore I set down my water-cans, one on top of the other, stepped up on them, and was soon over the top of the trench, crawling through the tall grass toward a clump of willows about fifty yards away. I passed two lonely graves with their wooden crosses hidden in depths of shimmering, waving green, and found an old rifle, its stock weather-warped and the barrel eaten away with rust. The ground was covered with tin cans, fragments of shell-casing, and rubbish of all sorts; but it was hidden from view. Men had been laying waste the earth during the long winter, and now June was healing the wounds with flowers and cool green grasses.

I was sorry that I went to the willows, for it was there that I found the sniper. He had a wonderfully concealed position, which was made bullet-proof with steel plates and sandbags, all covered so naturally with growing grass and willow bushes that it would have been impossible to detect it at a distance of ten yards. In fact, I would not have discovered it had it not been for the loud crack of a rifle sounding so close at hand. I crept on to investigate and found the sniper looking quite disappointed.

"Missed the blighter!" he said. Then he told me that it wasn't a good place for a sniper's nest at all. For one thing, it was too far back, nearly a half-mile from the German trenches. Furthermore, it was a mistake to plant a nest in a solitary clump of willows such as this: a clump of trees offers too good an aiming mark for artillery: much better to make a position right out in the open. However, so far he had not been annoyed by shell fire. A machine gun had searched for him, but he had adequate cover from machine-gun fire.

"But, blimy! You ought to 'a' 'eard the row w'en the bullets was a-smackin' against the sandbags! Somebody was a-knockin' at the door, I give you my word!"
