Bertram thanked him, and commenced to trace them upon his spare vest.

"Don't bother to do that," said the General. "Take this set of duplicates. The disposition of our forces is clearly marked in red ink, and their numerical strength certified by a chartered accountant. The only detail omitted is the number of women and children that will be placed in the firing-line. Today's bag has not yet been reported."

An aide-de-camp galloped into the tent, flung himself from his exhausted mule and saluted.

"In the name of our noble and august Kaiser," he began, "I have the honour to inform you that we have to-day captured 47 charwomen, 16 bedridden octogenarians and 21 babies in arms."

"Zwanzigheit!" exclaimed the General excitedly. "Place them in the forefront of our brave Bogey Head Hussars, and order the advance for ten o'clock to-morrow morning."

The aide-de-camp saluted, flung himself on to a fresh mule and galloped hell for leather to the canteen.

"I am much obliged for the information you have given me," said Bertram politely. "It is of paramount importance."

"You're quite welcome," remarked the General. "By-the-by, what do you want it for?"

Our hero rapidly shaved off Wigson's moustache and drew himself up proudly. "I am a spy," he said.
