In nearly every instance names have been suppressed. Only initials have been indicated, but sufficient description is attached to enable personal friends of those who are still so unfortunate as to be incarcerated to identify them and their present situation. Likewise, in the cases where I received kind treatment from Germans, initials only have been introduced, since the publication of their names would only serve to bring punishment upon them. H.C.M. [Illustration: Statutory Declaration] CHRONICLER'S NOTE On Friday afternoon, July 31, 1914, I shook hands in farewell with my friend Henry C. Mahoney. He was going to Warsaw and was full of enthusiasm concerning the new task which was to occupy him for at least three months. Owing to his exceptional skill and knowledge, practical as well as theoretical, of photography in all its varied branches, he had been offered, and had accepted an important appointment abroad in connection with this craft--one which made a profound appeal to him. Despite the stormy outlook in the diplomatic world he felt convinced that he would be able to squeeze through in the nick of time. Although he promised to keep me well informed of his movements months passed in silence. Then some ugly and ominous rumours came to hand to the effect that he had been arrested as a spy in Germany, had been secretly tried and had been shot. I did not attach any credence to these vague, wild stories. I knew he had never been to Germany before, and was _au courant_ with the harmless nature of his mission. A year elapsed before I had any definite news. Then to my surprise I received a letter from him dispatched from the Interned British Prisoners Camp at Ruhleben. As a matter of fact I learned subsequently that he had previously written six letters and post-cards to me, but none had reached me; most likely they had been intercepted and suppressed by the German authorities. The letter intimated that he had prepared a voluminous account of his experiences. Two or three days later I learned from another source that he had been "having a hard, rough, and exciting time," and that he could relate one of the most fascinating and sensational stories concerning the treatment meted out to our compatriots by the German authorities. I also learned that a closely written diary and a mass of other papers were on their way to me; that they were in safe keeping just over the frontier, the bearer waiting patiently for the most favourable moments to smuggle them into safety. This diary and other documents contained material which he desired me to make public with all speed in order to bring home to the British public a vivid impression of what our fellow-countrymen were suffering in the German prison camps.
