Various other documents of general interest, bearing on the causes of the war, have been included in this volume.
I do not attempt to mention all those who have helped in the preparation of this material. I cannot, however, pass over without acknowledgment the assistance I have received from Professors Munroe Smith and John Bassett Moore, of Columbia University, to whom I owe more than one important suggestion, while Professor James T. Shotwell also has given me the benefit of his valued criticism of the subject-matter and the arrangement of the material. Mr. Henry F. Munro has been kind enough to go over the proof, and Miss Isadore G. Mudge, of the Columbia University Library, has greatly facilitated my search for material and examination of sources.
