"I knew you were not. Here we are in the passage again, and it's as dark as a well. Mind your step, and, when we come out into the broader street, walk as if you had lived here all your life. But the town is half deserted. All the younger men have gone away to the war."

They came into the street and walked carelessly along, passing only an occasional old man or woman. The wonderful German mobilization, like a net, through which nothing slipped, was going on, and the youthful strength of the town was already departing toward the French border.

"No notice of us will be taken until we come to the outskirts," said Lannes, "but there they have sentinels whom we must pass."

It was on the tip of John's tongue to ask how, but he refrained. He was willing to put his trust in this young Frenchman who was proving himself so trustworthy, and he continued in silence by his side. It did not take them long to reach the area of scattered houses. Walking swiftly among them they entered a vegetable garden, and John saw beyond the metals of a railway track, a bridge, and two soldiers, gun on shoulder, guarding it.

"We're going to pass under that bridge," said Lannes.

Now John could not refrain from asking how.

"It crosses a canal and not a river," said Lannes. "It's an old disused canal, with but little water in it, and we'll go down its bed. Come on, John."

The canal flowed at the foot of the garden, and they lowered themselves into the bed, where they found a muddy footing, between the water and the bank, which rose four or five feet.

"We'll bend over and hug the bank," said Lannes. "In the darkness we may be able to go under the bridge, unseen by the two sentinels. At any rate we must chance it. If they fire on us the odds are at least twenty to one against our being hit. So, don't use the automatic unless the need is desperate."

A chill ran along John's spine. He had never fired at anybody, and nobody had ever fired at him. A week ago he was a peaceful tourist, never dreaming of bullets, and now he was fairly hurled into the middle of a gigantic war. But he was one who accepted facts, and, steadying himself for anything, he followed Lannes who, bent almost double, was walking rapidly.
