?28 in their power to assist, and it is incumbent on all local health authori- ties to keep the local railway officers in touch with the measures they intend to take, and to invite their co-operation in so far as railway colonies and station premises are concerned. As soon as the local health authorities are ready with their plans of campaign, they should inform the railway authorities of the steps they propose to take. Railway goods yards and stores are frequently known foci for plague, and whenever a local board or municipality carries out preventive measures in the vicinity, identical measures should be conducted simultaneously in the railway yards. 20. (ii) Persons.-Control of the movements of persons is of less importance than that of grain. The passport system has been dis- credited. The segregation of the sick is not essential. The disinfection of clothes and baggage is not generally practicable. In the case of towns it is well nigh impossible to give effect to the provisions of Plague Regulation No. 10. 21. Village boycott.-In the case of the ordinary village, there is no real reason why the headman should not compel persons suspected of coming from an infected place to have his clothes and personal effects sun-dried or, in the alternative, to remain outside for a couple of days. Nor should he have difficulty in preventing grain consignments from getting into his village until both grain and bags have been disinfected by the sun. In some parts of the Presidency this system of 'village boycott' has been adopted with success by the villagers on their own initiative. But there is reason to believe that villagers are not generally aware of the drastic powers with which their headmen are invested. 22. It is regrettable that in the past this very useful measure has been almost entirely neglected, and there seems to be great need for spreading information regarding this measure among the people of the Presidency. Where it has been adopted, it has proved of the greatest value, and all district health authorities should see that the people in their districts are made fully aware of their powers in this respect and of the value of these powers. 23. Evacuation may also be encouraged, but it rests with local bodies to provide accommodation for those who have been rendered homeless. Evacuation should be carefully controlled by the health staff who should see that temporary huts are erected on a convenient and suitable site and that they are occupied only after the bedding, clothing and other personal effects from the evacuated houses have been well exposed to the sun's rays. Emigration from infected to uninfected places is commonly responsible for the spread of plague, and local bodies and their health staffs should endeavour to control any such movement, and should en- courage villagers and townsfolk to carry out the method of village boycott already described. Plague refugees should at all times be accorded a very cold welcome. The close supervision of all such move- ments is, in any case, a very important duty devolving on district health staffs, and the duty is not rendered any easier when the people carry out these migrations, as they usually do, surreptitiously and during the hours of darkness. 24. (d) Inoculation.-Once plague has occurred or threatens to break out, no time should be lost in conducting an inoculation campaign. The protection that inoculation affords need not be enlarged upon here, but
