It may strike the reader as curious that I took Kim with me, but I knew he could be of tremendous use to me in Constantinople. In addition to speaking his _Kaffir_ dialects, he knew Arabic. Any negro boy who could speak Arabic could learn almost anything in Constantinople, which abounds in black men of all tribes and nationalities. Among the servants of every household, Kim would find many compatriots from whom he could get information, impossible for any European to obtain. After an uneventful trip to Constantinople, I took preliminary quarters in the Brasserie Kor, a quiet, second-rate hostelry on the Rue Osmanly. I went to an unpretentious place to avoid attracting any particular attention. Had I put up at an expensive hotel there would immediate]y bave been queries about me. Who is this stranger? He seems to have money. If it isn't his money, whose money is he spending? It is not well to invite a Turk's suspicion. As I was totally unacquainted with Constantinople, I used the first week for getting familiar with the geography of the city. It was necessary that I learn the location of the various legations and the residences of high court officials. The next week I found lodgings in the very center of the district of court residences and began to seek out the haunts and places of rendezvous of demi-mondaines, favorites and hangers-on of the Turkish officials. On the second day of my arrival, I had presented my credentials and letters at the German Pera Hospital, and had my name entered as a visiting honorary surgeon. Every day thereafter, rain or shine, I made it a point to spend some time at these hospitals, and it was well that I did. Once a day and often twice I would sign the book at the hospital and I believe that the signature Dr. Franz von Graver appears on the record books of the Pera and German Hospitals in Constantinople, at least one hundred times. Was I not fulfilling my duties as a physician doing research work?
