"It is certainly not impossible that the manuscript may yet lie concealed," remarked the Professor, at last, with assumed composure. "Instances of similar discoveries are not lacking. It is not long since that a ceiling of a room in the old house of the proprietor of my home was broken through; it was a double ceiling, and the empty space contained a number of records and papers concerning the ownership, and some old jewels. The treasure had been concealed in the time of the great war, and no one for a century had heeded the lowly ceiling of the little room." "Naturally," exclaimed Fritz, rubbing his hands. "And within the facing of old chimneys empty spaces are sometimes found. A brother of my mother's found, on rebuilding his house, in such a place a pot full of coins." He drew out his purse. "Here is one of them, a beautiful Swedish dollar; my uncle gave it to me at my confirmation as a luck-penny, and I have carried it in my purse ever since. I have often struggled against the temptation to spend it." The Professor closely examined the head of Gustavus Adolphus, as if he had been a neighbor of the concealed Tacitus, and would convey information concerning the lost book in its inscription. "It is true," he said, reflectively, "if the house is on a height, even the cellars may be dry." "Undoubtedly," answered the Doctor. "Often, too, the thick walls were built double, and the intervening space filled with rubbish. In such a case it would be easy, through a small opening, to make a hollow space in the inside of the wall." "But now," began the Professor, rising, "the question arises, what are we to do? For the knowledge of such a thing, whether it be of great or little importance, imposes upon the investigator the duty of doing all that is possible to promote the discovery. And this duty we must fulfill promptly and completely." "If you impart this record to the public, you will allow the prospect of discovering the manuscript to pass out of your own hands." "In this business, every personal consideration must be dismissed," said the Professor, decisively. "And if you now make known the cloister-record you have found," continued the Doctor, "who can answer for it, that the nimble activity of some antiquary, or some foreigner, may not prevent all further investigations? In such a case the treasure, even if found, would be lost, not only to you, but also to our country and to science." "That, at least, must not be," cried the Professor. "And besides, even if you apply to the government of the province, it is very doubtful whether they will render you any assistance," replied the Doctor, triumphantly.
