This book is in another sense the product of that visit. What I then saw and heard of contemporary America so fascinated me that--believing as I do that the key to every people is in its past--I could not rest until I had mastered all that I could of the history of my delightful hosts. This I sought as much as possible from the original sources, reading voraciously, and at the time merely for my pleasure, such records as I could get of old debates and of the speech and correspondence of the dead. The two existing histories, which I also read, and upon which I have drawn most freely, are that of the present President of the United States and that of Professor Rhodes, dealing with the period from 1850 to 1876. With the conclusions of the latter authority it will be obvious that I am in many respects by no means at one; but I think it the more necessary to say that without a careful study of his book I could neither have formed my own conclusions nor ventured to challenge his. The reading that I did at the time of which I speak is the foundation of what I have now written. It will be well understood that a Private in the British Army, even when invalided home for a season, has not very great opportunities for research. I think it very likely that errors of detail may be discovered in these pages; I am quite sure that I could have made the book a better one if I had been able to give more time to revising my studies. Yet I believe that the story told here is substantially true; and I am very sure that it is worth the telling. If I am asked why I think it desirable at this moment to attempt, however inadequately, a history of our latest Ally, I answer that at this moment the whole future of our civilization may depend upon a thoroughly good understanding between those nations which are now joined in battle for its defence, and that ignorance of each other's history is perhaps the greatest menace to such an understanding. To take one instance at random--how many English writers have censured, sometimes in terms of friendly sorrow, sometimes in a manner somewhat pharisaical, the treatment of Negroes in Southern States in all its phases, varying from the provision of separate waiting-rooms to sporadic outbreaks of lynching! How few ever mention, or seem to have even heard the word "Reconstruction"--a word which, in its historical connotation, explains all!
