On reaching Warsaw he asked one or two well-informed persons about this beautiful stranger. Only a few hours had passed before Prince Poniatowski, accompanied by other nobles, called upon her at her home.

"I am directed, madam," said he, "by order of the Emperor of France, to bid you to be present at a ball that is to be given in his honor to-morrow evening."

Mme. Walewska was startled, and her face grew hot with blushes. Did the emperor remember her escapade at Bronia? If so, how had he discovered her? Why should he seek her out and do her such an honor?

"That, madam, is his imperial majesty's affair," Poniatowski told her. "I merely obey his instructions and ask your presence at the ball. Perhaps Heaven has marked you out to be the means of saving our unhappy country."

In this way, by playing on her patriotism, Poniatowski almost persuaded her, and yet something held her back. She trembled, though she was greatly fascinated; and finally she refused to go.

Scarcely had the envoy left her, however, when a great company of nobles entered in groups and begged her to humor the emperor. Finally her own husband joined in their entreaties and actually commanded her to go; so at last she was compelled to yield.

It was by no means the frank and radiant girl who was now preparing again to meet the emperor. She knew not why, and yet her heart was full of trepidation and nervous fright, the cause of which she could not guess, yet which made her task a severe ordeal. She dressed herself in white satin, with no adornment save a wreath of foliage in her hair.

As she entered the ballroom she was welcomed by hundreds whom she had never seen before, but who were of the highest nobility of Poland. Murmurs of admiration followed her, and finally Poniatowski came to her and complimented her, besides bringing her a message that the emperor desired her to dance with him.

"I am very sorry," she said, with a quiver of the lips, "but I really cannot dance. Be kind enough to ask the emperor to excuse me."

But at that very moment she felt some strange magnetic influence; and without looking up she could feel that Napoleon himself was standing by her as she sat with blanched face and downcast eyes, not daring to look up at him.
