"In this story I depicted circles of life that were familiar to me since student days: the agricultural life of the country and the University life of the city. The reader will, I trust, discover in the characterizations of the work, that I have drawn cheerfully and unrestrainedly from this life at large. In the figures of the academical world he would seek in vain for special models, since Mr. and Mrs. Struvelius, Raschke, and others are types to whom in every German University single personalities will correspond. In the character of Professor Werner my friend Haupt has been recognized. But one can find in it only so much of the manner and method of Haupt, as a poet dares to take up of the being of a real man without interfering with the freedom of artistic creation, and without offending him through lack of delicacy. Haupt himself perceived with pleasure a certain remote resemblance, and of this connection with the romance he gave expression in his own way; having on several occasions, when sending me the prospectus of his Berlin lectures on the Latin historiographer Ammianus, good-humoredly signed himself 'Magister Knips,' which latter personage plays a sorrowful part in the story, and is only prevented from hanging himself by the thought of his professional researches in the Latin author mentioned. "Some years before the appearance of my 'Debit and Credit' Haupt had unexpectedly requested me to write a novel. This accorded at that time with secret designs of mine, and I promised him. To _The Lost Manuscript_ he contributed, however, in quite another manner. For as we were once sitting alone with one another at Leipsic, before he was called to Berlin, he disclosed to me in the greatest confidence, that somewhere in a small Westphalian town in the loft of an old house, lay the remains of a convent library. It was very possible that among them there was hidden a manuscript of the lost Decades of Livy. The master of this treasure, however, was, as Haupt had learned, a surly and quite inaccessible gentleman. Thereupon I put forward the proposition to travel together to the mysterious house, move the old fellow's heart, hoodwink him, and, in case of extreme necessity, drink him under the table, to secure the precious treasure. As Haupt had some confidence in my powers of seduction when joined with a good glass, he declared himself agreeable therewith, and we reveled in and developed to the fullest extent the pleasure we had in prospect of enlarging the tomes of the Roman historian for a grateful posterity. Nothing came of the affair; but the remembrance of the intended trip greatly helped me in developing the action of the novel.
