The Great War interrupted my own historical work, but in 1920 I returned to the original plan of a work on "Great Britain and the American Civil War" in the hope that the English materials obtained by Mr. Adams might be made available to me. When copies were secured by Mr. Adams in 1913 a restriction had been imposed by the Foreign Office to the effect that while studied for information, citations and quotations were not permissible since the general diplomatic archives were not yet open to students beyond the year 1859. Through my friend Sir Charles Lucas, the whole matter was again presented to the Foreign Office, with an exact statement that the new request was in no way related to the proposed "Life" of Charles Francis Adams, but was for my own use of the materials. Lord Curzon, then Foreign Secretary, graciously approved the request but with the usual condition that my manuscript be submitted before publication to the Foreign Office.
