I was making for that cramped little courtyard adjoining the shop of Mohammed er-Rahmân in which I had observed the presence of one of those narrow high-wheeled carts peculiar to the district, and as the entrance thereto from the Sûk was closed by a rough wooden fence I anticipated little difficult in gaining access. Yet there was one difficulty which I had not foreseen, and which I had not met with had I arrived, as I might easily have arranged to do, a little earlier. Coming to the corner of the Street of the Perfumers, I cautiously protruded my head in order to survey the prospect. Abû Tabâh was standing immediately outside the shop of Mohammed er-Rahmân! My heart gave a great leap as I drew back into the shadow, for I counted his presence of evil omen to the success of my enterprise. Then, a swift revelation, the truth burst in upon my mind. He was there in the capacity of _imám_ and attendant magician at the mystical "Blessing of the perfumes"! With cautious tread I retraced my steps, circled round the Mosque and made for the narrow street which runs parallel with that of the Perfumers and into which I knew the courtyard beside Mohammed's shop must open. What I did not know was how I was going to enter it from that end. I experienced unexpected difficulty in locating the place, for the height of the buildings about me rendered it impossible to pick up any familiar landmark. Finally, having twice retraced my steps, I determined that a door of old but strong workmanship set in a high, thick wall must communicate with the courtyard; for I could see no other opening to the right, or left through which it would have been possible for a vehicle to pass. Mechanically I tried the door, but, as I had anticipated, found it to be securely locked. A profound silence reigned all about me and there was no window in sight from which my operations could be observed. Therefore, having planned out my route, I determined to scale the wall. My first foothold was offered by the heavy wooden lock which projected fully six inches from the door. Above it was a crossbeam and then a gap of several inches between the top of the gate and the arch into which it was built. Above the arch projected an iron rod from which depended a hook; and if I could reach the bar it would be possible to get astride the wall. I reached the bar successfully, and although it proved to be none too firmly fastened, I took the chance and without making very much noise found myself perched aloft and looking down into the little court. A sigh of relief escaped me; for the narrow cart with its disproportionate wheels stood there as I had seen it in the morning, its shafts pointing gauntly upward to where the moon of the Prophet's nativity swam in a cloudless sky. A dim light shone out from the square window of Mohammed er-Rahmân's cellar.
