"Dr. Heidegger's Experiment," with which the present volume opens, is Hawthorne's earliest treatment of the elixir of immortality theme, which haunted him throughout his life and was the subject of the unfinished romance which rested upon his coffin. He handles it daintily, poetically here, with an irony at once exquisite and profound. "The Birthmark" represents another favorite theme: the rivalry between scientific passion and human affection. It is not wholly free from the morbid fancy which Hawthorne occasionally betrays, and which allies him, on one side of his many-gifted mind, with Edgar Allan Poe; but the essential sanity of Hawthorne's moral, and the perfection of the workmanship, render "The Birthmark" worthy of its high place among modern short stories. "Ethan Brand" dates obviously from the sojourn at North Adams, Massachusetts, described in the "American Note-Book." Fragmentary as it is, it is one of Hawthorne's most powerful pieces of writing, the Unpardonable Sin which it portrays--the development of the intellect at the expense of the heart--being one which the lonely romancer himself had had cause to dread. The motive of the humorous character sketch entitled "Wakefield" is somewhat similar: the danger of stepping aside, even for a moment, from one's allotted place. "Drowne's Wooden Image" is a charming old Boston version of the artistic miracles made possible by love. In "The Ambitious Guest," the familiar story of the Willey House, in the Notch of the White Hills, is told with singular delicacy and imaginativeness, while "The Great Stone Face," a parable after Hawthorne's own heart, is suggested by a well-known phenomenon of the same mountainous region. Hawthorne's numerous tales based upon New England history are represented by one of the briefest, "The Gray Champion," whose succinct opening and eloquent close are no less admirable than the stern passion of its dramatic climax.
