"It certainly is getting sultry," assented Captain Bob. "Let's try that place yonder. One may as well get killed by falling bricks inside as by T.N.T. in the open."

His voice grew very solemn as he added: "I believe it was in front of that place that our battalion got its fearful gruelling, and poor old A company was wiped out."

It was the only building anywhere visible, and a zigzag walk between shell craters brought them to it.

A bristling hedge of very thick barbed wire was the first thing they encountered; but, thanks to another star-shell, they discovered an opening at the back leading to what had evidently been a brewery in the piping times of peace. The shattered sheds about the yard and the half-ruined main building had been sandbagged and strengthened by the enemy's engineers, as though they had intended to hold it.

But for some reason or other it was now deserted. The machine-guns had been removed from their positions, and there were signs of a hasty and recent exodus. The tall shaft of the chimney-stack stood sentinel over the deserted place; but as the two brothers penetrated into the main building, the thought that was in both their minds was voiced by Dennis.

"I believe we've touched lucky," he said. "You're right, old chap; they don't want to hit this show for some reason best known to themselves."

A perfect hurricane of shells was passing on either side of the ruined brewery from batteries not very far behind it, and it was a relief to steal inside the big dark chamber where the thunder seemed less loud.

"I've still got my torch," said Dennis in a low voice, after an anxious pause. "I wonder if it would be safe to have a look round the place?"

"Why not?" replied Bob. "There must be water somewhere here, and my throat is like the sole of an old boot. If there had been anyone hiding, we should have heard them by this time."

Dennis turned on his light, and the beam showed them that the ground floor of the building had been utilised as a bathroom. Rows of vats and coppers were ranged along one side, and a network of pipes communicated with some large stoves, in one of which there was still a handful of red embers.
