In the final chapter 24 - "Conclusion," there is no direct mention of Indians. Once again, however, Hawthorne, shows us imagery relating to Chillingworth's meddling with the weeds that he harvested. Chillingworth took his healing instincts and understanding of healing herbs learned from the Indians and transformed them into evil jealousy and revenge that ruined his life and the life of Dimmesdale.
Nothing was more remarkable than the change which took place, almost immediately after Mr. Dimmesdale's death, in the appearance and demeanour of the old man known as Roger Chillingworth. All his strength and energy--all his vital and intellectual force--seemed at once to desert him; insomuch that he positively withered up, shrivelled away, and almost vanished from mortal sight, like an uprooted weed that lies wilting in the sun. This unhappy man had made the very principle of his life to consist in the pursuit and systematic exercise of revenge; and when, by its completest triumph and consummation, that evil principle was left with no further material to support it,--when, in short, there was no more devil's work on earth for him to do, it only remained for the unhumanized mortal to betake himself whither his Master would find him tasks enough, and pay him his wages duly.
