Jack looked uneasily at the marquis, and was about to speak when the aid returned and requested the marquis to enter.

"Monsieur Marche, remain here, I beg you," said the marquis, coolly; "I shall call you presently. It is a service I ask of you. Will you oblige me?"

"Yes," said Jack.

The door opened for a second.

Napoleon III. sat at the long table, his head drooping on his breast; he was picking absently at threads in the texture of the table-cloth. That was all Jack saw—a glimpse of a table covered with half-empty glasses and fruit, an old man picking at the cloth in the lamplight; then the door shut, and he was alone in the dark hall. Out on the terrace he heard the tramp of the cuirassier sentinels, and beyond that the uproar of artillery, passing, always passing. He stared about in the darkness, he peered up the staircase into the gloom. A bat was flying somewhere near—he felt the wind from its mousy wings.

Suddenly the door was flung open beside him, and the marquis called to him in a voice vibrating with passion. As he entered and bowed low to the Emperor, he saw the marquis, tall, white with anger, his blue eyes glittering, standing in the centre of the room. He paid no attention to Jack, but the Emperor raised his impassible face, haggard and gray, and acknowledged the young man's respectful salutation.

"You have asked me a question," said the marquis, harshly, "and I demanded to answer it in the presence of a witness. Is your majesty willing that this gentleman shall hear my reply?"

The Emperor looked at him with half-closed, inscrutable eyes, then, turning his heavy face to Jack's, smiled wearily and inclined his head.

"Good," said the marquis, apparently labouring under tremendous excitement. "You ask me to give you, or sell you, or loan you my secret for military balloons. My answer is, 'No!'"

The Emperor's face did not change as he said, "I ask it for your country, not for myself, monsieur."
