Book excerpt: A reissue of Edward Rowe Snow's first book, covering the legends and history of nearly every rock and island in Boston Harbor, including Boston Light and Graves Light. The first (1935) edition resulted from research Snow did at Harvard under the tutelage of the great maritime historian Samuel Eliot Morison. When the 1971 edition of the book was published, a critic for the Boston Post wrote, "Mr. Snow has the gift of making his subject vivid and personal in its anecdotal touches . . . It is a volume of chatty yet dignified essays, with many a light touch brought in." This centennial edition contains the complete 1971 text, with annotations by Jeremy D'Entremont to bring the information up to date.
