e, Philip?" asked Julie.

"In one hour, my sister. There is not much rest for the _Arrow_ and me
these days, but they are such days as happen perhaps only once in a
thousand years, and one must do his best to be worthy. I'm not
preaching, little sister, don't think that, but I must answer to every
call."

The twilight had spread from east to west. The heavy shadows in the east
promised a dark night, but out of the shadows, as always, came that
sullen mutter of the ruthless guns. Julie shivered a little, and glanced
at the dim sky.

"Must you go up there in the cold dark?" she said. "It's like leaving
the world. It's dangerous enough in the day, but you have a bright sky
then. In the night it's terrible!"

"Don't you fear for me, little sister," said Lannes. "Why, I like the
night for some reasons. You can slip by your enemies in the dark, and if
you're flying low the cannon don't have half the chance at you. Besides,
I've the air over these regions all mapped and graded now. I know all

"But I believe, Mr. Scott, that you are right," said Julie.

"He'll certainly come to us at Menouville tomorrow night," said John,
speaking in English--all the conversation hitherto had been in French,
"and I think we'll have a pleasant ride through the forest in the
morning, Miss Lannes. You'll let me call you Miss Lannes, once or twice,
in my language, won't you? I like to hear the sound of it."

"I've no objection, Mr. Scott," she replied also in English. She did not
blush, but looked directly at him with bright eyes. John was conscious
of something cool and strong. She was very young, she was French, and
she had lived a sheltered life, but he realized once more that human
beings are the same everywhere and that war, the leveler, had broken
down all barriers.

"I've not heard who is to be our
