"They're working like beavers," he said, "and, if the Boche doesn't twig the game for another half-hour, we'll have enough cover scooped out to go on without losing too many men from their fire."

Riley chuckled. "It's working fine," he said. "I'm only hoping that some ruffian doesn't spoil the game by crawling out and finding our General is no more than a false alarm."

"That would queer the pitch," agreed Brock, "but I don't fancy any one will try it. They all know the working party is liable to be discovered at any minute, and any one out in the open when that comes off, is going to be in a tight corner."

"There's a good many here," said Riley, "that would chance a few tight corners if they knew five thousand francs was at the other side of it; but I took the precaution to hint gently to Clancy that our machine gun was going to keep on spraying lead round the General all night, to discourage any private enterprise."

"Anyhow," said Brock, "I suppose the whole regiment's in it, and flatter themselves this trifle of digging is for the special benefit of their pockets. But what are those fellows of ours supposed to be digging at in the corner there!"

"That," whispered the Little Lad, grinning, "is merely an improving of the amenities of the listening-post and the beginning of a dugout shelter from bombs; at least, that's Clancy's suggestion, though I have a suspicion there will be no hurry to roof-in the dug-out and that its back-door will travel an unusual length out."

"Well, so long," said Brock; "I must sneak along again and have a look at the digging."

It was when he was half-way back to the main trench that it became apparent the German suspicions were aroused, and that something—a movement after a light flared, perhaps, or the line of a parapet beginning to show above the grass—had drawn their attention to the work.

Light after light commenced to toss in an unbroken stream from their parapet in the direction of the working party, and a score of bullets, obviously aimed at them, hissed close overhead.

"Glory be!" said Rifleman McRory, flattening himself to the ground. "It's a good foot and a half I have of head-cover, and I'm thinking it's soon we will be needing it, and all the rest we can get."
