Suddenly a startling apparition dashed through the thick cloud of smoke--a man whose head and body were completely encased in steel. With arms outstretched the Hun staggered towards the Diggers, coughing violently the while under the irritating influence of the smoke-bomb.

"Collar him!" ordered Captain Nicholson.

A dozen hands seized him. His head-dress was removed, disclosing the features of a pale, insignificant, and spectacled German.

"What a cheek!" exclaimed M'Turk. "Fancy a worm like that holding us up!"

"Science against brute force, chum," remarked the Corporal, pointing to an anti-gas apparatus that dangled from the man's neck. "If it hadn't been that the gadget was smashed we might have gone on bombing till the end of the war."

The prisoner's armour was certainly proof against fragments of bombs, even at close range, as the splayed marks upon the steel testified. With the anti-gas apparatus he had been able to withstand the choking fumes, until a chance splinter of metal had perforated the flexible pipe between the Hun's mouth and the oxygen-container hidden under his back-plate. Although his arms and legs were unprotected, the man had practically escaped injury from the bombs, since the fragments of the exploded missile flew upwards. A gash on the knuckle of his right hand and a few slight scratches on the calves of his legs were the total result of the Anzacs' efforts until the smoke-bomb came into play.

"A chirpy little sausage-eater!" exclaimed Captain Nicholson, who, like his men, was not backward in acknowledging bravery even in an enemy. "See that he is sent back, Corporal. Now, lads, why was he so determined? There's more in this dug-out than meets the eye, I believe. I mean to find out. Who'll back me up?"
