There was no doubt it was the original low German text of the famous ballad, which had hitherto been lost to the world, that lay bodily before him. He was as pleased as a child with a Christmas-box. Then he read the letter, and when he came to the end, he read it again. He laughed. It was clearly all a roguish jest. But from whom? His thoughts turned first to Laura, but she had only the evening before treated him with cold contempt. Ilse was not to be thought of, and such playful mischief was very unlike the Professor. What did the house No. 10 mean? The young actress who lived there was said to be a very charming and enterprising young lady. Was it possible she could have any knowledge of folk-songs, and, the Doctor could not help thinking, a tender feeling for himself? The good Fritz chanced to step before the mirror for a moment, and he at once uttered an inward protest against the possibility of such an idea, and, laughing, he went back to his writing-table and to his popular song. He could not enter into the pleasantry, that was clear, but it was a pity. He laid the Robber Toss Bowl aside, and returned to his work. After a time, however, he took it up again. This valuable contribution had been sent to him, at all events, without any humiliating condition; perhaps he might be allowed to keep it. He opened a portfolio of old folk-songs, and placed it in its order as if it had been his own. Having laid the treasure in its proper place, he restored the portfolio to the bookshelf, and thought, it is a matter of indifference where the sheet lies.
