Mrs. Mason accordingly sent for Dr. Knight, who, on arrival, turned out to be her nephew's old acquaintance. Although the young men had been united by no greater intimacy than the superficial comradeship resulting from a winter in neighboring quarters, they were very well pleased to come together again. Horace Knight was a young man of good birth, good looks, good faculties, and good intentions, who, after a three years' practice of surgery in the army, had undertaken to push his fortune in Mrs. Mason's neighborhood. His mother, a widow with a small income, had recently removed to the country for economy, and her son had been unwilling to leave her to live alone. The adjacent country, moreover, offered a promising field for a man of energy,--a field well stocked with large families of easy income and of those conservative habits which lead people to make much of the cares of a physician. The local practitioner had survived the glory of his prime, and was not, perhaps, entirely guiltless of Mrs. Mason's charge, that he had not kept up with the progress of the "new diseases." The world, in fact, was getting too new for him, as well as for his old patients. He had had money invested in the South,--precious sources of revenue, which the war had swallowed up at a gulp; he had grown frightened and nervous and querulous; he had lost his presence of mind and his spectacles in several important conjunctures; he had been repeatedly and distinctly fallible; a vague dissatisfaction pervaded the breasts of his patrons; he was without competitors: in short, fortune was propitious to Dr. Knight. Mason remembered the young physician only as a good-humored, intelligent companion; but he soon had reason to believe that his medical skill would leave nothing to be desired. He arrived rapidly at a clear understanding of Ferdinand's case; he asked intelligent questions, and gave simple and definite instructions. The disorder was deeply seated and virulent, but there was no apparent reason why unflinching care and prudence should not subdue it. "Your strength is very much reduced," he said, as he took his hat and gloves to go; "but I should say you had an excellent constitution. It seems to me, however,--if you will pardon me for saying so,--to be partly your own fault that you have fallen so low. You have opposed no resistance; you haven't cared to get well." "I confess that I haven't,--particularly. But I don't see how you should know it." "Why it's obvious."
