"Dead as mutton," reported Wilmshurst, after bringing his glasses to bear upon the ill-starred Hun. "He nearly had me, though," he soliloquised, tentatively fingering the double perforation in his helmet.

There was no lack of volunteers to examine the sniper's lair. Regardless of the risk of being potted at by other enemy riflemen Bela Moshi, Tari Barl, and Spot Cash crept forward, taking advantage of every available bit of cover.

In twenty minutes the Haussas returned, reporting in characteristically native terms that the German's head had been literally riddled with the burst of bullets from the Maxim. They brought his rifle and ammunition, his field glasses and a small electric battery. In connection with the latter wires were run from the sniper's lair to the bush from which the puffs of smoke had been seen. Here small charges of black powder had been placed so as to be exploded from a safe distance and thus deceive the Haussas as to the rifleman's actual position. The Hun was a bit of a strategist, but he had overreached himself. It was the dense smoke from the black powder that had given him away. Had he used the so-called smokeless powder the Haussas might have expended hundreds of rounds without discovering the cheat.

Wilmshurst examined the weapon that had so nearly done him in. It was an improved Mauser, bearing the German Government proof mark and the date 1917, and was fitted with the latest approved type of telescopic sight, while on the muzzle was fixed a small metal cylinder that effectually silenced the report.

"That's strange, sir," he remarked to the major. "We distinctly heard the report."

"We did," agreed the company commander. "I cannot understand it unless the Boche for some reason fired several rounds with the silencer removed. If so, why?"

Before the discussion could be carried further a dull, booming sound came from behind the table-land of M'ganga, while at a little height behind the German position appeared the mushroom-like cloud of white smoke as the shrapnel burst.

"Good!" ejaculated the company commander, replacing his binoculars. "We've had the orchestral selection; the curtain rises on the First Act."
