Fourth, inspectors have also been placed to guard the region of Tiflis against the introduction of the plague from both Persia and Turkey. For the reasons above mentioned, it seems to me probable that if the plague reaches Europe, it will likely do so by way of Turkey in Asia, across the Bosporus into Constantinople. The large number of pilgrims passing along this route, with the Turk's well-known fatalistic belief, render it quite probable that infection gathered anywhere along the route may be carried into Europe. Since several places in Hedjaz, along the eastern shore of the Red Sea, have already become infected with the plague, it is by no means improbable that the disease may find its way into the Balkan Peninsula. There are also several centers of infection along the shores of the Persian Gulf. It will be seen from these statements that Mohammedan pilgrims are exposed to the infection. Indeed, already the disease has been detected among these pilgrims on steamships in the Red Sea. Certain international measures for the restriction of the plague were formulated at the Sanitary Convention of Venice in 1897. Nearly all civilized nations sent representatives to this conference, and certain general rules were adopted. Recognizing the fact that Mohammedan pilgrims from infected districts in India, coming to Mecca and other places along the eastern shore of the Red Sea, would mingle with those of like faith from Turkey and northern Africa, special rules concerning pilgrims were adopted at this conference. It should be understood, however, that these rules are likely to prove efficient safeguards only among those pilgrims who travel by sea. In the first place, the conference made certain regulations concerning the construction and sanitary arrangements of pilgrim ships. The upper deck must be kept clear for these people, and on the main covered deck every pilgrim has to have at least sixteen square feet of surface. Every one embarking on a pilgrim vessel must pass a medical inspection. No sick person or one suspected of having an infectious disease is allowed to go on board. The number which the vessel is allowed to carry is determined beforehand, and the names of all passengers and their home residences are recorded. The ship must supply wholesome water and make provision for food, proper in quality and sufficient in quantity. Every vessel carrying pilgrims must have on board a medical officer and a disinfecting stove. Details are given concerning the sanitary regulations during the voyage. All pilgrims are landed on the island of Camaran, in the Red Sea, before being allowed to disembark on the last stage of their journey. The period of detention from healthy ships at this place extends through only three days. If no disease appears during this time, the pilgrims are allowed to embark again, and go directly to Jeddah. If disease appears either before or after landing at Camaran, the pilgrims are detained at least
