Septimius took little or no notice of the raillery of the grim old doctor, but employed the rest of the time in getting as much information as he could out of his guest; and though he could not bring himself to show him the precious and sacred manuscript, yet he questioned him as closely as possible without betraying his secret, as to the modes of finding out cryptic writings. The doctor was not without the perception that his dark-browed, keen-eyed acquaintance had some purpose not openly avowed in all these pertinacious, distinct questions; he discovered a central reference in them all, and perhaps knew that Septimius must have in his possession some writing in hieroglyphics, cipher, or other secret mode, that conveyed instructions how to operate with the strange recipe that he had shown him. "You had better trust me fully, my good sir," said he. "Not but what I will give you all the aid I can without it; for you have done me a greater benefit than you are aware of, beforehand. No--you will not? Well, if you can change your mind, seek me out in Boston, where I have seen fit to settle in the practice of my profession, and I will serve you according to your folly; for folly it is, I warn you." Nothing else worthy of record is known to have passed during the doctor's visit; and in due time he disappeared, as it were, in a whiff of tobacco-smoke, leaving an odor of brandy and tobacco behind him, and a traditionary memory of a wizard that had been there. Septimius went to work with what items of knowledge he had gathered from him; but the interview had at least made him aware of one thing, which was, that he must provide himself with all possible quantity of scientific knowledge of botany, and perhaps more extensive knowledge, in order to be able to concoct the recipe. It was the fruit of all the scientific attainment of the age that produced it (so said the legend, which seemed reasonable enough), a great philosopher had wrought his learning into it; and this had been attempered, regulated, improved, by the quick, bright intellect of his scholar. Perhaps, thought Septimius, another deep and earnest intelligence added to these two may bring the precious recipe to still greater perfection. At least it shall be tried. So thinking, he gathered together all the books that he could find relating to such studies; he spent one day, moreover, in a walk to Cambridge, where he searched the alcoves of the college library for such works as it contained; and borrowing them from the war-disturbed institution of learning, he betook himself homewards, and applied himself to the study with an earnestness of zealous application that perhaps has been seldom equalled in a study of so quiet a character. A month or two of study, with practice upon such plants as he found upon his hill-top, and along the brook and in other neighboring localities, sufficed to do a great deal for him. In this pursuit he was assisted by Sibyl, who proved to have great knowledge in
