It has not been possible to adhere to any very definite method of arrangement. Many of the cartoons were drawn long after the events with which they deal took place, as, for instance, the Wittenberg pictures. The typhus outbreak amongst the prisoners at Wittenberg happened in December, 1914, but the facts were not made public until May, 1916. On the other hand, the cartoon depicting Count von Bernstorff's dismissal from Washington was published two years before he was handed his passports. It was a cartoon based upon the activities of Dumba. A great number of cartoons, particularly those published during the early months of the war, have no direct historical significance. The Belgian cartoons constitute a general indictment of the German method of warfare, while the Nurse Cavell drawings (Vol. II.) represent a specific comment upon an actual example of that method. The letterpress has been compiled mainly from official _communiques_ and reports, and from the speeches and public statements of the leading men of the belligerents and some of the neutrals. I have also quoted freely from newspapers, magazines, and books, and whenever possible I have made acknowledgment of these sources. My object has been not to explain the cartoons, but to show their great value as historical documents and to make sure, so far as is possible, that the basis of truth upon which they rest shall not be forgotten. J. MURRAY ALLISON. NEW YORK, Christmas Day, 1917. NOTE ON THE BELGIAN CARTOONS The cartoons which appear on the following pages up to and including page 86 call for special reference. They represent Raemaekers' impression of the behaviour of the German troops in Belgium during the first weeks of the invasion. The great majority of them were drawn long before any Official Reports were published, and not, as would seem natural, as illustrations of the Reports which were eventually published by the Belgian, French, and British Governments. The cartoon on page 86 was drawn after the publication of the British Government's Official Report. It is important to realise this. It is also necessary to remember that the German atrocities began actually at the moment that the German troops crossed the frontier on the evening of August 3rd and continued in unabated violence until the defeat at the Marne.
