Similarly, booking to the stations immediately on either side of Shikarpur was prohibited in order to prevent evasion of the Shikarpur inspection, and book- ing to Tando-Thoro, a small station, distant two miles from Hy- derabad in Sind, was prohibited in order to prevent evasion of inspec- tion at this latter place. To prevent evasion of inspection at the important station of Khanpur, the Government of the Punjab insti- tuted a system of moveable inspections. Attention was drawn to the fact that some passengers evaded the inspection at Khanpur by alighting at other stations and walking across country to rejoin the railway at some place beyond. Arrangements were therefore made under which the inspecting medical officer varied the place of inspection from day to day. Ten stations, situated above or below Khanpur, were appointed inspection stations ; and in the event of cases being discovered in the course of the inspection at any of these places, the suspects were to be sent for treatment and observation either to Khanpur or to Sher Shah. The rules issued by the Government of Madras provide that, if a passenger from an infected district appears to be attempting to evade inspection by alighting at a station short of that for which his ticket is taken, he shall be obliged to continue his journey as far as the next inspection station. The Bengal Regu- lations of November 1897 contain the following rule :- " In the event of a traveller from an infected area alighting at an intermediate station with the object of obtaining a fresh ticket, so as to conceal the fact that he comes from an infected area, the railway police will take down his name and the number of the fresh ticket issued, and will send information down the line, so that he may, on alighting, be placed under observation." Lighting of stations, and travellers by goods trains. Minor matters on which orders were issued by the Government of India were the proper lighting of inspection stations, and the notifi- cation to the inspecting officers of the carrying of passengers by goods trains. Results. The result of the carefully devised scheme of inspection which has now been described proved the efficacy of the arrangements. Leaving aside the outbreaks at Khandraoni and Hardwar and the cases that infected these places, only 67 cases of plague escaped across the Bombay and Sind frontier during the first period of the epidemic, of these 57 were detected at inspection stations along the railway routes. Thus, so far as is known, only 10 cases of plague were introduced 42
