These I have spoken of are the upper classes from the harems of the sultan and rich pashas, but those you see constantly on foot in the streets are the middle and lower classes, and not so attractive. They have fine eyes, but the yashmaks are thicker, and you feel there is less beauty hidden under them. The higher the rank the thinner the yashmak is the rule. They also wear the long cloak, but it is made of black or colored alpaca or a similar material. Gray is most worn, but black, brown, yellow, green, blue and scarlet are often seen. The negresses dress like their mistresses in the street, and if you see a pair of bright yellow boots under a brilliant scarlet ferraja and an unusually white yashmak, you will generally find the wearer is a jet-black negress. Sitting so much in the house _à la Turque_ is not conducive to grace of motion, nor are loose slippers to well-shaped feet, and I must confess that a Turkish woman walks like a _goose_, and the size of her "fairy feet" would rejoice the heart of a leather-dealer. [Illustration: ENTERING A MOSQUE.] We have been to see the Howling Dervishes, and I will endeavor to give you some idea of their performances. Crossing to Scutari in the steam ferryboat, we walked some distance till we reached the mosque, where the services were just commencing. The attendant who admitted us intimated that we must remove our boots and put on the slippers provided. N---- did so, but I objected, and the man was satisfied with my wearing them over my boots. We were conducted up a steep, ladder-like staircase to a small gallery, with a low front only a foot high, with no seats but sheepskins on the floor, where we were expected to curl ourselves up in Turkish fashion. Both my slippers came off during my climb up stairs, and were rescued in their downward career by N----, who by dint of much shuffling managed to keep his on. Below us were seated some thirty or forty dervishes. The leader repeated portions of the Koran, in which exercise others occasionally took part in a quiet manner. After a while they knelt in line opposite their leader and began to chant in louder tones, occasionally bowing forward full length. Matters down below progressed slowly at first, and were getting monotonous. One of my feet, unaccustomed to its novel position, had gone to sleep, and I was in a cramped state generally. Moreover, we were not the sole occupants of the gallery: the sheepskins were full of them, and I began to think that if the dervishes did not soon begin to howl, _I_ should. Some traveler has said that on the coast of Syria the Arabs have a proverb that the "sultan of _fleas_ holds his court in Jaffa, and the grand vizier in Cairo." Certainly some very high dignitary of the realm presides over Constantinople, and makes his head-quarters in the mosque of the Howling Dervishes. [Illustration: CASTLE OF EUROPE, ON THE BOSPHORUS.]
