Bourne undertook to write the Life of Motley for Houghton, Mifflin and Company's American Men of Letters series, and he had done considerable work in the investigation of material. He was editor of a number of publications, one of which was John Fiske's posthumous volume, "New France and New England," and he wrote critical notices for the _Nation_, _New York Tribune_, and the _New York Times_. As I have said, he had a large family to support, and he sought work of the potboiling order; but in this necessary labor he never sacrificed his ideal of thoroughness. A remark that he made to me some while ago has come back with pathetic interest. After telling me what he was doing, how much time his teaching left for outside work, why he did this and that because it brought him money, he said: "I can get along all right. I can support my family, educate my children, and get a little needed recreation, if only my health does not break down." Bourne took great interest in the American Historical Association, and rarely if ever missed an annual meeting. He frequently read papers, which were carefully prepared, and a number of them are printed in the volume of Essays to which I have referred. He was the efficient chairman of the programme committee at the meeting in New Haven in 1898; and as chairman of an important committee, or as member of the Council, he attended the November dinners and meetings in New York, so that he came to be looked upon as one of the chief supporters of the Association. Interested also in the _American Historical Review_, he was a frequent contributor of critical book notices.
