Feisal’s correspondence with his father was an adventure in itself. They communicated by means of old retainers of the family, men above suspicion, who went up and down the Hejaz Railway, carrying letters in sword-hilts, in cakes, sewn between the soles of sandals, or in invisible writings on the wrappers of harmless packages. In all of them Feisal reported unfavourable things, and begged his father to postpone action till a wiser time.
