I looked at her in surprise. Her cheeks were flushed brilliantly, and I would have given much to have seen the expression of her eyes, which her mask half hid.

"Why, if you would let me help you——" I began, but she interrupted, pressing my arm tighter.

"Let me go alone, please, kleine Amerikanerin." Her voice was pleading and oddly intense. "It's only such a short time—and, believe me, there is nothing wrong, really. I shall thank you always."

Before I had an opportunity to reply she had slipped away in the crowd. To say I was amazed were to put it mildly. I was dumfounded. Two points alone seemed clear in my mind: first, that Fräulein Hartmann had no idea of spending a half-hour in sewing on a few inches of ruffle; second, that whatever her motive for remaining away might be, it was "nothing wrong"; her frank, sweet nature utterly forbade such an idea.

Rather troubled, I caught up quickly with the others of the party and entered the box to find Lieutenant Blum and Lieutenant Linder waiting. They looked surprised at seeing me alone, and I hastily explained the situation. Lieutenant Linder then suggested that we three take a stroll about the hall, and we started off, I talking very rapidly, in the hope of turning their attention from the Fräulein's continued absence. I would not have been a woman had I not myself been a bit curious about her. We made a tour of the room and at length came to the head of a flight of stairs. I declared that I was dying of curiosity to discover what lay at the foot, so we descended and found ourselves in the very midst of a forest. On every side extended paths lined with trees whose branches met above in arches. At the end of one of the paths we saw a log hut. Above, through interlaced branches, shone a silver moon. I could not help exclaiming at the beauty of the illusion.

There were countless little arbors and retreats where couples were sitting out dances. We had just started to turn down the path to the right, when I caught sight of a rose-colored dress in one of these arbors. A step farther and I saw that the girl leaning against the bench was Fräulein Hartmann. Her head was thrown back in a characteristic attitude and her lips were parted, as though eagerly listening to the words of her companion. He—for of course it was a man—was a broad-shouldered fellow, with a smooth face and a sword-cut on his forehead. Bending forward, he looked up intently into the face of the girl, talking very earnestly, very rapidly, as if pleading a case under pressure of time.

Quick as a flash I wheeled about and faced the others, for the path was only broad enough for us to proceed in single file. I declared this walk stupid; the hut was the only thing really worth seeing; whereupon my bodyguard, although laughing at the capriciousness of my sex, obediently followed. How long I lingered about that wretched hut I can't say. At last, when every pretext was gone, I made my way back again upstairs. What a sigh of relief I gave when we reached the box, for there sat Fräulein Hartmann, smiling in her sweet, plaintive fashion, and talking to her aunt and Herr Doktor with the utmost self-possession. A moment later we had whirled away among the dancers, and I did not have an opportunity to exchange a word with her alone.

At twelve o'clock the orchestra stopped playing for an hour and supper was served. Half of the people had been eating and drinking the entire evening, for tables had been spread in the boxes from the opening of the ball. This did not, however, seem to make any difference in the keenness of their appetites now. We had a very jolly time in our box, for beside the pensionnaires were several Americans. Among them were Mr. and Mrs. Albert Sterner. You are doubtless familiar with the delightful work of Mr. Sterner. He has won considerable reputation, especially for his illustrations. Both he and his wife added much merriment to the party, for they are very entertaining. The ball began again at one, but no one thought of going home till four o'clock. We left Lieutenant Linder still dancing.

"This lasts till five," he explained, as he took us to our carriage. "I shall get a cup of coffee at the restaurant, change to my uniform, and be ready for Dienst (service) at six. I really haven't time to go to bed."

I captured two very pretty souvenirs of the occasion, one of which you shall have to decorate your den. Every one who went down on the floor wore a favor made of blue ribbon, fastened with a gold head of Folly. Lieutenant Linder and Herr Martens both presented me with theirs, and in spite of acquiring a habit for greediness, I smilingly accepted both, with a thought for you. They will look extremely well tacked to an American wall.
