"The trouble is," he explained, "the orficer seems to think the 'osts of the enemy is goin' to move about us just now. Where should I be then? They'd all think I'd 'ad the wind up and 'opped it. An' then, 'ow about shell-fire? Just bein' invisible won't stop no Perishin' Percies. What I want is something—well, you know what I mean. Can't you get me something to keep off the bullets?"

"Verily that can I," said Eustace, with an air suggesting that Alf was simply wasting his time with niggling details. "Just such a thing as thou desirest was aforetime in the treasury of the great King Uz; my spirits shall procure it for thee. Whoso weareth this can come to no hurt through weapons forged by man."

"That's the ticket, if Mr. What's-'is-name won't be wanting it for 'isself. 'E's probably 'elpin' with this 'ere War somewhere or other."

"Uz hath been dead these many cycles—upon him be peace!" returned Eustace. He raised his hand, and, with an awesome clang, a cumbrous suit of armor, complete in every detail, fell into the trench. The djinn wore an expression of mild triumph. This time, he seemed to think, even this strange new master of his must be satisfied. He was not in the least prepared for Alf's reception of his performance.

"Take it away," shrieked Private Higgins, in an agony at the idea of having to explain away such a phenomenon to his superiors. "Take it away, you blinkin' fool, and 'op it yerself. What the blazes d'you think yer doin'? 'Ere, get out of it, quick. Somebody's comin'."

Somebody was.

The whole of Number Nine Platoon, awakened from its slumbers, came tumbling out of its dug-outs, adjusting its gas masks as it came. A horrible ghoul, dimly recognizable through the windows of its respirator as Sergeant Lees, came and gibbered at Alf.

"What's up, sergeant?" asked Alf in amazement.

"Gas!" replied the sergeant, removing his mouthpiece for a moment in order to speak more clearly. "Why the 'ell ain't you got yer mask on? Didn't you 'ear the gong?"

Higgins realized with horror what had happened. The clang of the armor had been mistaken for a gas-gong by a sentry in the next bay, who had promptly given the alarm. He tried feebly to straighten matters out; but it was too late now. The word had spread; the Boche, seeing the commotion in our lines, had sprung to arms; and both armies stood tense, each convinced that the other was going to make a surprise attack. A heavy fusillade with rifles and machine guns, rifle grenades and trench mortars began, and in its turn spread along the lines with great swiftness. Then somebody put up an S.O.S. flare, and the guns, which had only been waiting for this invitation, joined in. For the next few minutes the Messina earthquake or an eruption of Vesuvius would have been welcomed as quiet interludes by Richards, Allen & Co.
