"Go you," commanded Angus, his voice rising to a more than usually Highland inflection, "and semaphore to Mucklewame that when he hears the explosion of this"—he pulled out the safety-pin of the grenade and gripped the grenade itself in his enormous paw—"followed, probably, by the temporary cessation of the machine-gun, he is to bring his men over here in a bunch, as hard as they can pelt. Put it as briefly as you can, but make sure he understands. He has a good signaller with him. Send Bogle to report when you have finished. Now repeat what I have said to you…. That's right. Carry on!"

M'Snape was gone. Angus, left alone, pensively restored the safety-pin to the grenade, and laid the grenade upon the ground beside him. Then he proceeded to write a brief letter in his field message-book. This he placed in an envelope which he took from his breast pocket. The envelope was already addressed—to the Reverend Neil M'Lachlan, The Manse, in a very remote Highland village. (Angus had no mother.) He closed the envelope, initialled it, and buttoned it up in his breast pocket again. After that he took up his grenade and proceeded to make a further examination of the premises. Presently he found what he wanted; and by the time Bogle arrived to announce that Sergeant Mucklewame had signalled "message understood," his arrangements were complete.

"Stay by this small hole in the wall, Bogle," he said, "and the moment the Lewis gun arrives tell them to mount it here and open fire on the enemy gun."

He left the room, leaving Bogle alone, to listen to the melancholy rustle of peeling wall-paper within and the steady crackling of bullets without. But when, peering through the improvised loophole, he next caught sight of his officer, Angus had emerged from the house by the cellar window, and was creeping with infinite caution behind the shelter of what had once been the wall of the estaminet's back-yard (but was now an uneven bank of bricks, averaging two feet high), in the direction of the German machine-gun. The gun, oblivious of the danger now threatening its right front, continued to fire steadily and hopefully down the street.

Slowly, painfully, Angus crawled on, until he found himself within the right angle formed by the corner of the yard. He could go no further without being seen. Between him and the German gun lay the cobbled surface of the street, offering no cover whatsoever except one mighty shell-crater, situated midway between Angus and the gun, and full to the brim with rainwater.

A single peep over the wall gave him his bearings. The gun was too far away to be reached by a grenade, even when thrown by Angus M'Lachlan. Still, it would create a diversion. It was a time bomb. He would—

He stretched out his long arm to its full extent behind him, gave one mighty overarm sweep, and with all the crackling strength of his mighty sinews, hurled the grenade.

It fell into the exact centre of the flooded shell-crater.

Angus said something under his breath which would have shocked a disciple of Kultur. Fortunately the two German gunners did not hear him. But they observed the splash fifty yards away, and it relieved them from ennui, for they were growing tired of firing at nothing. They had not seen the grenade thrown, and were a little puzzled as to the cause of the phenomenon.

Four seconds later their curiosity was more than satisfied. With a muffled roar, the shell-hole suddenly, spouted its liquid contents and other débris straight to the heavens, startling them considerably and entirely obscuring their vision.
