But to return to Cairo. We netted a good deal of small fry, but only landed one big fish during the time I was attached. He was a Mesopotamian and a very respectable old gentleman, who followed the calling of astrologer and peripatetic quack--a common combination and admirably adapted for distributing propaganda. He came from Stamboul through Athens with exemplary credentials, and might have got through to India, which was the landfall he proposed to make, if his propagandist energy had not led him to deviate on a small side-tour in Egypt. Here we got on his track, and I boarded the Port Said express at short notice while he and the "ferret" who had picked him up got into a third-class compartment lower down. As the agent made no signal after the train had pulled out, I knew our man had not got the bulk of his propaganda with him, otherwise I had powers to hold up the express, for it was more important to get his stuff than the man himself. At Port Said he had a chance of seeing me, thanks to the agent's clumsiness, and I had to shave my beard off and buy a sun-helmet in consequence, for I was travelling in the same ship along the Canal to see that he did not communicate with troops on either side of the bank, and on the slightest suspicion he would have put his stuff over the side. All went smoothly and he was arrested in Suez roads by plain-clothes men with a sackful of seditious literature for printing broadcast in India. Of course they arrested the "ferret" too, as is usual in these cases. I went ashore with them in the police-launch as a casual traveller and was amused to hear the agent rating the old man for not having prophesied this mishap when telling his fortune the night before. The propagandist was merely interned in a place of security--it was not our policy to make martyrs of such men, especially when they were _bona fide_ Ottoman subjects. I was rather out of touch with the pan-Islamic movement during the summer of 1915, as my lungs had become seriously affected on the Canal, and the trouble became so acute that I had to spend two or three months in the hills of Cyprus. Before I had been there a week the G.O.C. troops in Egypt cabled for me to return and proceed to Aden as political officer with troops. I was too ill then to move and had to cable to that effect. My chagrin at missing a "show" was much alleviated when I heard what the show was. As it had a marked effect on the pan-Islamic campaign by enhancing Turkish prestige, it is not out of place to give some account of it here. While I was still on the Canal in February (1915) a "memo" was sent for my information from Headquarters at Cairo to say that the Turks had invaded the Aden protectorate at Dhala, where I once served on a boundary commission.
