"Serious," he said solemnly. "At any moment these pigs of Prussians may cross the frontier. Only one thing will hold them back: the fear of your English fleet. You are fortunate, you English, in having the sea around your country, yet I think you do not give sufficient thought towards the significance of the fact."

"But Great Britain has not declared war on Germany."

"No, not yet, but perhaps soon. Your country would do incalculable service to France and Belgium simply by holding the sea; yet in addition she has generously pledged herself to send almost the whole of her army to Belgium if the Germans attack us. Then the rest will be a question of time. We in Liége will do our utmost to keep the invaders at bay until your brave army arrives. Then, with the French, to say nothing of the Russians on the east, Germany will be assailed and conquered, and the vile spectre of Teutonic militarism will be for ever laid low."

The Belgian major spoke with conviction. His earnestness in the hope of British aid was intense.

"And we are ready," continued the major. "Already the bridges across the Meuse are mined; our armoured forts will defy the heaviest of the German artillery. We will keep the Germans at bay for a month if need be. Meanwhile you two messieurs journey through Belgium as calmly as if you were on an English country road. You English are brave, but you are enigmas. But take this and show it if you are challenged," and he wrote out a pass on an official form.

The major accompanied his involuntary guests as far as the edge of the glacis. This time they were not blindfolded; yet there was very little to be seen, except to the practised eye of a trained man. There were mountings for quick-firing guns, and just discernible above the turf the rounded tops of the steel cupolas. Beyond that the fort looked nothing more than an earthworked enclosure.

Somewhat to the lads' astonishment they found their motor-cycles placed on a trolley. The Belgian soldiers, not understanding the action of the exhaust lever, had been unable to wheel the heavy mounts; and since their orders had to be obeyed, they had first resorted to the toilsome task of carrying the mounts. This, owing to the heat of the day and the thickness of their clothing, was eventually abandoned, and a trolley procured.

"You have a clear road," announced Major Résimont. "When you re-enter the lane, keep to the left; that will bring you speedily upon the highway. Au revoir, messieurs!"

Somewhat to the wonderment of the Belgian soldiers, who could not understand how the unwieldy machines could be moved by manual power, the lads took a running start. Both engines fired easily, and soon the tourists were speeding along through the outskirts of the city of Liége.
