"I say, what's this wheeze about Liége?" persisted Harrington. "There's something in the wind, old chap."

"It's not exactly Liége I want to see," replied Kenneth, "although it's a fine, interesting old place, with a history. Fact is, my sister Thelma is at a boarding-school at Visé—that's only a few miles farther on—and we might just as well look her up."

"By Jove! I ought to have remembered. I knew she was somewhere in Belgium. Let me see, she's your youngest sister?"

"Twelve months my junior," replied Kenneth, "and a jolly good pal she is, too. It's rather rough luck on her. The pater's just off on that Mediterranean trip, so she hasn't been able to go home for the holidays. We'll just cheer her up a bit."

Rollo gave a final glance at the map before folding it and placing it in his pocket. In response to a summons, the garçon produced the bill and gratefully accepted the modest tip that Everest bestowed upon him with becoming public schoolboy dignity.

This done, the two lads took their travelling cases and made their way to the hotel garage, where their motor-cycles had been placed under lock and key, out of the reach of sundry inquisitive and mischievous Belgian gamins.

"Hello! What's the excitement?" asked Kenneth, pointing to a crowd of gesticulating townsfolk gathered round a notice that had just been pasted to a wall.

"Ask me another," rejoined his companion. "A circus or something of the sort about to turn up, I suppose. If you're curious I'll hang on here while you go and find out."

Kenneth was off like a shot. Half-way across the bridge that here spans the Meuse he nearly collided with the proprietor of the Hôtel Doré. The man's face was red with excitement.

"Quel dommage!" he exclaimed, in reply to the lad's unspoken question. "The Government has ordered the army to mobilize. What inconsideration! Jules, Michel, Georges, and Étienne—all will have to go. I shall be left without a single garçon. And the busy season approaches also."
