In summing up the expedition, Mr. Wavell was disposed to attribute his success not to any histrionic gifts of his own, but to the ignorance of the inhabitants of the Holy Cities, and their lack of interest in the outside world, even the Islamic world. "There are so many different sects in Islam, and its adherents are found in so many different countries, that I seriously believe that if some one invented for himself a country and a language that did not exist at all, and journeyed thus to Mecca, no one there would know enough geography to find him out. Yet with all, they are quick enough in their way, and if some Mutowif would take the trouble to write a book on ethnography in its relation to the Islam of to-day, and classify the different races that come to Mecca, such a deception as I practised would become impossible." They did, as a matter of fact, excite a certain suspicion, and their two servants, though they were Persians and knew little Arabic, must have had their own views. The great assets of the travellers were their knowledge of Arabic and Moslem ceremonial, and the fact that Mr. Wavell took up his disguise long before he approached the Hedjaz. He considered that Medina was much the more dangerous place of the two, and that no traveller should go there who was not thoroughly at home in his oriental character. Whatever may be said, the journey is one of extreme danger and delicacy, and demands not only great knowledge, but perpetual vigilance. It must be remembered that a European is all the time in the midst of a fanatical and devout people, and that the highest merit would be acquired by any one who might discover and denounce the unbeliever. In spite of every precaution there must be an enormous element of luck, and Mr. Wavell's conclusion is that his escape was due rather to a series of happy chances than to his own good management.
