The intellectual and the social were closely blended in the Boston of the sixties and the seventies, and Mrs. Moulton was in the very midst of the most characteristically Bostonian circles. Her journals record how she went to a "great party" given by Mrs. William Claflin, whose husband was afterward governor; to Cambridge to a function given by the Agassizs; to a reception at Dr. Alger's "to meet Rose Terry," later known as Rose Terry Cooke; to a dinner given in honor of Miss Emily Faithful; to one intellectual gayety after another. She was one of the attractive figures at the delightful Sunday evening reunions given by Mr. and Mrs. Edwin P. Whipple. She notes in the journal that at a brilliant reception given by Mrs. John T. Sargent, so well known as the hostess of the famous Chestnut Street Radical Club, she had "a few golden moments" with Emerson, and a talk with the elder Henry James, with whom she was a favorite. In 1870 Mrs. Moulton became the Boston literary correspondent of the _New York Tribune_. This work developed under her care into one of much importance. Boston publishers sent to her all books of especial interest, and her comments upon them were of solid value. She recorded the brilliant meetings of the Chestnut Street Radical Club, and the intellectual news in general. These letters made a distinct success. Extracts from them were copied all over the United States, and they came to be looked upon as a sort of authorized report of what was doing in the intellectual capital of the country. They were given up only when the desire for foreign travel drew Mrs. Moulton so much abroad that she could no longer keep as closely in touch with current events as is necessary for a press correspondent. The Radical Club at that time was famed throughout the entire country, and it was regarded as the very inner temple wherein the gods forged their thunderbolts. Only those who bore the sacramental sign were supposed to pass its portals. Mrs. Moulton's accounts of these meetings were vivid and significant. As, for instance, the following: "The brightest sun of the season shone, and the balmiest airs prevailed, on the 21st of December, in honor of the meeting of the Radical Club under the hospitable roof of Mr. and Mrs. John T. Sargent in Chestnut street. Mrs. Howe was the essayist, and there was a brilliant gathering to hear her. David Wasson was there, and John Weiss, and Colonel Higginson, and Alcott, hoary embodiment of cool, clear thought. Mr. Linton, the celebrated engraver, John Dwight of the _Musical Journal_, Mrs. Severance, the beloved president of the New England Woman's Club, bonny Kate Field of the honest eyes and the piquant pen, Mrs. Cheney, Miss Peabody, and many others, distinguished in letters or art.
