The attitude of the four men now as they watched the gunners at work was almost characteristic of each. Larry, who had relatives or friends in most branches of the Service, was able to tell the others something of the methods of modern artillery, and delivered almost a lecturette upon the subject. Billy Simson was frankly bored by this side of the subject, but intensely interested in the noise and the spectacular blinding flash that appeared to leap forth in a twenty-foot wall of flame on the discharge of each gun. Pug found a subject for mirth and quick, bantering jests in the attitudes of the gunners and their movements about the gun, and the stentorian shoutings through a megaphone of the Sergeant-Major from the entrance to a dug-out in the rear of the guns. Lee sat down, leisurely rolled and lit a cigarette, watched the proceedings with interest, and made only a very occasional soft drawled reply to the remarks of the others. “Do you mean to tell me,” said Pug incredulously, breaking in on Arundel’s lecture, “that them fellows is shootin’ off all them shells without ever seein’ what they’re firin’ at? If that is true, I calls it bloomin’ waste.” “They do not see their target,” said Arundel, “but they are hitting it every time. You see they aim at something else, and they’re told how much to the right or left of it to shoot, and the range they are to shoot at--it is a bit too complicated to explain properly, but it gets the target all right.” “Wot’s the bloke with the tin trumpet whisperin’ about?” asked Pug. “Looks to me as if he was goin’ to be a casualty with a broke blood-vessel.” “Passing orders and corrections of fire to the guns,” explained Arundel. “There’s a telephone wire from that dug-out up to somewhere in front, where somebody can see the shells falling, and ’phone back to tell them whether they are over or short, right or left.” “It’s pretty near as good as a Brock’s benefit night,” said Billy Simson; “but I’d want cotton wool plugs in my ears, if I was takin’ up lodgin’s in this street.”
