179 4. When a large body of troops or police or coolies en- gaged in plague operations are returning to a healthy district, previous intimation of their departure should be given to the local authorities of the place of destination. Before starting, they should be carefully examined and disinfected, and on arrival at their destination, they should be given passports according to the rules. (G.O., No. 835-P., dated 2nd June 1899.) 5. Persons who pass to and fro between an infected and a healthy district should be kept under surveillance, but a passport need not be issued to them more than once during each period of ten days. (G.O., No. 1080-P., dated 15th September 1898.) 6. Passport-issuing officers should not suppose that they have merely to issue passports to those who come and apply for them. The main object of declaring persons from infected parts to be bound to take out passports is to punish cases of wilful evasion of the rules, and it was never the intention to relieve the passport-issuing officers of their duty of tracing out such passengers and not allowing them to go away without passports. Passengers who fail to take out passports should be prosecuted at the discretion of the Collector, but whether prosecuted or not, they must be required to present them- selves for inspection for ten days as soon as their arrival has been detected. (G.O., No. 741-P., dated 2nd August 1898.) 7. Arrangements should be made to have all arrivals at large towns like Salem, Trichinopoly, Madura not only ex- amined by a medical subordinate at the railway platform, but also similarly inspected daily for ten days afterwards. The Collectors concerned must see that this is done and should not leave the matter wholly into the hands of Municipal Chairmen. At stations where medical subordinates are not available for the duty of watching arrivals, granting them passports and inspecting them for ten days, the work should be entrusted to stationmasters or competent persons already in the employ of Government, and if they are found neglecting their duty, they should be prosecuted. Collectors are requested to check their action carefully from time to time. (G.O., No. 1105-P., dated 17th September 1898.) 8. Passport-issuing officers should note that every person who holds a ticket marked in the manner indicated in para- graphs 14 and 16 of section 6 of this Chapter, should be given a passport. To ensure that none escapes taking a passport,
