"It is an army coming," said the marquis.
"It is a rout," said Jack, quietly.
The marquis moved suddenly, as though to avoid a blow.
"What troops are those?" he asked, after a silence.
"It is the French army," replied Jack. "Have you not heard the cannonade?"
"No--my machines make some noise when I'm working. I hear it now. What is that cloud--a fire?"
"It is the battle cloud."
"And the smoke on the horizon?"
"The smoke from the guns. They are fighting beyond Saarbrück--yes, beyond Pfalzburg and Wörth; they are fighting beyond the Lauter."
"Wissembourg?"
"I think so. They are nearer now. Monsieur de Nesville, the battle has gone against the French."
"How do you know?" demanded the marquis, harshly.
"I have seen battles. One need only listen and look at the army yonder. They will pass Morteyn; I think they will pass for miles through the country. It looks to me like a retreat towards Metz, but I am not sure. The throngs of troops below are fugitives, not the regular geometrical figures that you see to the north. Those are regiments and divisions moving towards the west in good order."
The two men stepped back into the room and faced each other.
"After the rain the flood, after the rout the invasion," said Jack, firmly. "You cannot know it too quickly. You know it now, and you can make your plans."
He was thinking of Lorraine's safety when he spoke, but the marquis turned instinctively to a mass of machinery and chemical paraphernalia behind him.
"You will have your hands full," said Jack, repressing an angry sneer; "if you wish, my aunt De Morteyn will charge herself with Mademoiselle de Nesville's safety."
"True, Lorraine might go to Morteyn," murmured the marquis, absently, examining a smoky retort half filled with a silvery heap of dust.
"Then, may I drive her over after dinner?"
"Yes," replied the other, indifferently.
Jack started towards the stairs, hesitated, and turned around.
"Your inventions are not safe, of course, if the German army comes. Do you need my help?"
"My inventions are my own affair," said the marquis, angrily.
Jack flushed scarlet, swung on his heels, and marched out of the room and down the stairs. On the lower steps he met Lorraine's maid, and told her briefly to pack her mistress's trunks for a visit to Morteyn.
Lorraine was waiting for him at the window where he had left her, a scared, uncertain little maid in truth.
"The battle is very near, isn't it?" she asked.
"No, miles away yet."
"Did you speak to papa? Did he send word to me? Does he want me?"
