In compiling the following pages i have had access to certain sources of official information, the nature of which i am not at liberty to specify further. i have used these freely in such chapters of this book as deal with recent and contemporary events in turkey or in Germany in connection with turkey: the chapter, for instance, entitled 'deutsch-land fiber Allah,' is based very largely on such documents. i have tried to be discriminating in their use, and have not, as far as i am aware, stated anything derived from corroborative evidence. With regard to the Armenian massacres i have drawn largely on the testimony collected by Lord Bryce, Toynbee in his pamphlet the murder of a nation, and the murderous tyranny of the Turks, and on the pamphlet by Dr. Martin niepage, called the horrors of Aleppo.
