Quarantine, protective cordons, train inspections, and the like, have been tried, and found rather worse than useless; as like all other systems that interfere with personal liberty, they lead to concealment of cases, and concealment necessarily involves the treatment of the sick under circumstances that render the spread of the disease to relatives and attendants almost certain. At the same time, measures of this class are those that are regarded with most favour by natives, and provided they are assured that, in case of the discovery of cases, there will be no forcible interference with their habits and customs, they will generally adopt and themselves carry out the more useful and practicable of the measures of this class, such as the watching of new comers by road and rail, and even the inspection of the dead. It is a mistake to think they are not as anxious to keep the pestilence out of their towns as their European rulers can be, and, as a rule, they will make no objection to the proper disinfection of houses that have become infected, but they will prefer to run any risk rather than submit to any interference with their domestic customs. (5) The means of thorough disinfection should be provided. The best of all disinfectants is fire, and, as far as possible, all infected bedding, clothing and rubbish should be burned, and paid for. In order to secure, to some extent, the destruction of rats and other vermin, as a preliminary measure, the house should be fumigated by means of sulphur fumes, and after this has been completed and the house opened, the floor, walls and furniture should be thoroughly washed down with strong solution of corrosive sublimate (¹⁄₁₀₀₀) thoroughly acidified with hydrochloric acid. Phenyl has also proved serviceable. The men employed in this work should have been, if possible, inoculated. They should thoroughly grease all exposed parts of the skin before commencing work, and should be thoroughly clothed, being made to wear nether garments reaching to the ankles and tucked into boots of European pattern, which should be kept well greased, so that they may not get hard from contact with the disinfecting solutions. I cannot recommend the digging up of earthen floors, as the task is undoubtedly a very dangerous one to the men employed in the work, and there can be no possible real need for it, as, of all parts of a dwelling, the floor is that which can most easily be saturated with powerful disinfectants.
