In Chapter 9 - "The Leech," Hawthorne makes five references to Indians. Chillingworth and Dimmesdale become housemates as well as doctor and patient. Hawthorne focuses on Chillingworth's professional medicinal use of healing herbs that he learned from the Indians. A rumor exists that Chillingworth had engaged in suspicious chants with the Indians. These might be compared to rumors of evil incantations of the Black man of the forest.
To such a professional body Roger Chillingworth was a brilliant acquisition. He soon manifested his familiarity with the ponderous and imposing machinery of antique physic; in which every remedy contained a multitude of far-fetched and heterogeneous ingredients, as elaborately compounded as if the proposed result had been the Elixir of Life. In his Indian captivity, moreover, he had gained much knowledge of the properties of native herbs and roots; nor did he conceal from his patients, that these simple medicines, Nature's boon to the untutored savage, had quite as large a share of his own confidence as the European pharmacopoeia, which so many earned doctors had spent centuries in elaborating.
Such was the young clergyman's condition, and so imminent the prospect that his dawning light would be extinguished, all untimely, when Roger Chillingworth made his advent to the town. His first entry on the scene, few people could tell whence, dropping down, as it were, out of the sky, or starting from the nether earth, had an aspect of mystery, which was easily heightened to the miraculous. He was now known to be a man of skill; it was observed that he gathered herbs, and the blossoms of wild-flowers, and dug up roots and plucked off twigs from the forest-trees, like one acquainted with hidden virtues in what was valueless to common eyes.
In this manner, the mysterious old Roger Chillingworth became the medical adviser of the Reverend Mr. Dimmesdale. As not only the disease interested the physician, but he was strongly moved to look into the character and qualities of the patient, these two men, so different in age, came gradually to spend much time together. For the sake of the minister's health, and to enable the leech to gather plants with healing balm in them, they took long walks on the seashore, or in the forest; mingling various talk with the plash and murmur of the waves, and the solemn wind-anthem among the tree-tops. Often, likewise, one was the guest of the other, in his place of study and retirement. There was a fascination for the minister in the company of the man of science, in whom he recognized an intellectual cultivation of no moderate depth or scope; together with a range and freedom of ideas, that he would have vainly looked for among the members of his own profession.
On the other side of the house, old Roger Chillingworth arranged his study and laboratory; not such as a modern man of science would reckon even tolerably complete, but provided with a distilling apparatus, and the means of compounding drugs and chemicals, which the practised alchemist knew well how to turn to purpose.
Two or three individuals hinted, that the man of skill, during his Indian captivity, had enlarged his medical attainments by joining in the incantations of the savage priests; who were universally acknowledged to be powerful enchanters, often performing seemingly miraculous cures by their skill in the black art. A large number--and many of these were persons of such sober sense and practical observation, that their opinions would have been valuable, in other matters--affirmed that Roger Chillingworth's aspect had undergone a remarkable change while he had dwelt in town, and especially since his abode with Mr. Dimmesdale.
