"I am Doctor Jabez Portsoaken," said the stranger, "late surgeon of his Majesty's sixteenth regiment, which I quitted when his Majesty's army quitted Boston, being desirous of trying my fortunes in your country, and giving the people the benefit of my scientific knowledge; also to practise some new modes of medical science, which I could not so well do in the army." "I think you are quite right, Doctor Jabez Portsoaken," said Septimius, a little confused and bewildered, so unused had he become to the society of strangers. "And as to you, sir," said the doctor, who had a very rough, abrupt way of speaking, "I have to thank you for a favor done me." "Have you, sir?" said Septimius, who was quite sure that he had never seen the doctor's uncouth figure before. "Oh, ay, me," said the doctor, puffing coolly,--"me in the person of my niece, a sickly, poor, nervous little thing, who is very fond of walking on your hill-top, and whom you do not send away." "You are the uncle of Sibyl Dacy?" said Septimius. "Even so, her mother's brother," said the doctor, with a grotesque bow. "So, being on a visit, the first that the siege allowed me to pay, to see how the girl was getting on, I take the opportunity to pay my respects to you; the more that I understand you to be a young man of some learning, and it is not often that one meets with such in this country." "No," said Septimius, abruptly, for indeed he had half a suspicion that this queer Doctor Portsoaken was not altogether sincere,--that, in short, he was making game of him. "You have been misinformed. I know nothing whatever that is worth knowing." "Oho!" said the doctor, with a long puff of smoke out of his pipe. "If you are convinced of that, you are one of the wisest men I have met with, young as you are. I must have been twice your age before I got so far; and even now, I am sometimes fool enough to doubt the only thing I was ever sure of knowing. But come, you make me only the more earnest to collogue with you. If we put both our shortcomings together, they may make up an item of positive knowledge." "What use can one make of abortive thoughts?" said Septimius. "Do your speculations take a scientific turn?" said Doctor Portsoaken. "There I can meet you with as much false knowledge and empiricism as you can bring for the life of you. Have you ever tried to study spiders?--there is my strong point now! I have hung my whole interest in life on a spider's web." "I know nothing of them, sir," said Septimius, "except to crush them when I see them running across the floor, or to brush away the festoons of their webs when they have chanced to escape my Aunt Keziah's broom."
