But it was here that I realized that there was something sinister in the background, for so suspicious were the hotel people that when, for two days I was seriously unwell, not one of them would come in answer to my bell but an old woman, who flatly refused to bring me anything and never turned up again. I lived on Brand's beef lozenges till I was well enough on the evening of the second day to crawl downstairs and bribe a waiter to fetch me some milk. Once recovered I went to Pirot by rail in spite of pressing requests that I would return to Belgrade. I wanted to see the Pirot carpet factories, but of course no one believed this. They all imagined, as I learnt later, that I was bound for Bulgaria with evil intentions: messages from Montenegro for the undoing of Serbia. I was quite unaware at the time that Prince Ferdinand and Prince Nikola were plotting together. Arrived at Pirot it was obvious that I was considered dangerous. I was stopped in the station by police and military authorities, who had doubtless been warned of my arrival, and told that I was not to go near the Bulgar frontier, much less cross it. Only after some argument did they consent to let me stay two days in the town. Then I was to leave for Belgrade by the early morning train, and to make sure that I could not escape by any other route, they confiscated my passport and said it should be returned to me at the station when I left. Tension between Serbia and Bulgaria was obviously extreme. By way of warning, I was told that a Bulgar spy had just been caught and was in prison. But I had come to see the carpet making and I saw it. The carpets are very interesting. They are made in no other part of Serbia and are in truth Bulgarian in origin. Pirot before its annexation to Serbia in 1878 was an undoubtedly Bulgar district. Old books of travel call Nish Bulgar. In Pirot a distinctly Bulgar cast of countenance and build is to be seen. And the neighbouring peasants play the bagpipe, the typical Bulgar instrument. The type extends not only into the south of Serbia (of 1902), but in the east spreads over the Timok. The population along the frontier and around Zaitchar I found Bulgar and Roumanian, the flat-faced, heavily built Bulgar with high cheekbones and lank black hair predominating--all being Serbized, of course. Having seen the carpet making at Pirot, I obediently appeared at the railway station at the appointed time as bidden. Suddenly, the whole atmosphere changed. The same officials who had received me so inimically now wanted me to stay! Having first worn my quite respectable supply of patience almost threadbare, the Serbs turned right round and did all they could to efface first impressions. The whole thing seemed to me childish and astonishing. But I profited largely by it and went the rest of my way in comparative comfort.
