"Open," called Jack; "I must see you!"
"I am busy!" replied the marquis. Irritation and surprise were in his tones.
"Open!" called Jack again; "there is no time to lose!"
Suddenly the door was jerked back and the marquis appeared, pale, handsome, his eyes cold and blue as icebergs.
"Monsieur Marche—" he began, almost discourteously.
"Pardon," interrupted Jack; "I am going into your room. I wish to look out of that turret window. Come also—you must know what to expect."
Astonished, almost angry, the Marquis de Nesville followed him to the turret window.
"Oh," said Jack, softly, staring out into the sunshine, "it is time, is it not, that we knew what was going on along the frontier? Look there!"
On the horizon vast shapeless clouds lay piled, gigantic coils and masses of vapour, dark, ominous, illuminated by faint, pallid lights that played under them incessantly; and over all towered one tall column of smoke, spreading above like an enormous palm-tree. But this was not all. The vast panorama of hill and valley and plain, cut by roads that undulated like narrow satin ribbons on a brocaded surface, was covered with moving objects, swarming, inundating the landscape. To the south a green hill grew black with the human tide, to the north long lines and oblongs and squares moved across the land, slowly, almost imperceptibly—but they were moving, always moving east.
"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?"
He found it hard to tell her what message her father had sent, but he did.
"I am to go to Morteyn? Oh, I cannot! I cannot! Papa will be alone here!" she said, aghast.
"Perhaps you had better see him," he said, almost bitterly.
She hurried away up the stairs; he heard her little eager feet on the stone steps that led to the turret; climbing up, up, up, until the sound was lost in the upper stories of the house. He went out to the stables and ordered the dog-cart and a wagon for her trunks. He did not fear that this order might be premature, for he thought he had not misjudged the Marquis de Nesville. And he had not, for, before the cart was ready, Lorraine, silent, pale, tearless, came noiselessly down the stairs holding her little cloak over one arm.
"I am to stay a week," she said; "he does not want me." She added, hastily, "He is so busy and worried, and there is much to be done, and if the Prussians should come he must hide the balloon and the box of plans and formula—"
"I know," said Jack, tenderly; "it will lift a weight from his mind when he knows you are safe with my aunt."
"He is so good, he thinks only of my safety," faltered Lorraine.
"Come," said Jack, in a voice that sounded husky; "the horse is waiting; I am to drive you. Your maid will follow with the trunks this evening. Are you ready? Give me your cloak. There—now, are you ready?"
"Yes."
He aided her to mount the dog-cart—her light touch was on his arm. He turned to the groom at the horse's head, sprang to the seat, and nodded. Lorraine leaned back and looked up at the turret where her father was.
"Allons! En route!" cried Jack, cheerily, snapping his ribbon-decked whip.
At the same instant a horseless cavalryman, gray with dust and dripping with blood and sweat, staggered out on the road from among the trees. He turned a deathly face to theirs, stopped, tottered, and called out—"Jack!"
"Georges!" cried Jack, amazed.
