They found the doctor seated in his little study, clad in his dark camblet robe of knowledge, with his black velvet cap, after the manner of Boorhaave, Van Helmont, and other medical sages:  a pair of green spectacles set in black horn upon his clubbed nose, and poring over a German folio that seemed to reflect back the darkness of his physiognomy.  The doctor listened to their statement of the symptoms of Wolfert’s malady with profound attention; but when they came to mention his raving about buried money, the little man pricked up his ears.  Alas, poor women! they little knew the aid they had called in.

Dr. Knipperhausen had been half his life engaged in seeking the short cuts to fortune, in quest of which so many a long lifetime is wasted.  He had passed some years of his youth in the Harz mountains of Germany, and had derived much valuable instruction from the miners, touching the mode of seeking treasure buried in the earth.  He had prosecuted his studies also under a travelling sage who united all the mysteries of medicine with magic and legerdemain.  His mind, therefore, had become stored with all kinds of mystic lore:  he had dabbled a little in astrology, alchemy, and divination; knew how to detect stolen money, and to tell where springs of water lay hidden; in a word, by the dark nature of his knowledge he had acquired the name of the High German doctor, which is pretty nearly equivalent to that of necromancer.  The doctor had often heard rumors of treasure being buried in various parts of the island, and’ had long been anxious to get on the traces of it.  No sooner were Wolfert’s waking and sleeping vagaries confided to him, than he beheld in them the confirmed symptoms of a case of money-digging, and lost no time in probing it to the bottom.  Wolfert had long been sorely depressed in mind by the golden secret, and as a family physician is a kind of father confessor, he was glad of the opportunity of unburthening himself.  So far from curing, the doctor caught the malady from his patient.  The circumstances unfolded to him awakened all his cupidity; he had not a doubt of money being buried somewhere in the neighborhood of the mysterious crosses, and offered to join Wolfert in the search.  He informed him that much secrecy and caution must be observed in enterprises of the kind; that money is only to be digged for at night; with certain forms and ceremonies; the burning of drugs; the repeating of mystic words, and above all, that the seekers must be provided with a divining rod, which had the wonderful property of pointing to the very spot on the surface of the earth under which treasure lay hidden.  As the doctor had given much of his mind to these matters, he charged himself with all the necessary preparations, and, as the quarter of the moon was propitious, he undertook to have the divining rod ready by a certain night.[5]
