2. The collection and bacteriological examination of all dead rats. Facilities for the collection of rats in the quarters are provided in the shape of small covered bins attached to lamp posts, telephone posts, electric light poles, etc. These bins contain a carbolic acid disinfectant, and the inhabitants are invited to at once put into them all rats found or killed by them. There are 650 of these bins distributed throughout the city and its suburbs, and each of them is visited twice daily by rat collectors who take all rats found by them to the City Bacteriologist. Each rat is at once labelled with the number of the bin from which it is taken, and if subsequently found to be plague infected, a special survey is immediately made of the block of houses in that vicinity. All rat-holes and rat runs are filled up with broken glass and cement, defective gratings and drains dealt with, and rat poison distributed free to the occupants. If several plague-infected rats are found in one locality, a special house-to-house survey and cleansing of that district is made. 3. The destruction of rats by poison, traps and birdlime boards; special efforts in this direction being made just before the onset of the regular plague season which is in the months of from March to July. 4. The encouraging of the community to keep cats. 5. The systematic cleaning and washing out of all native dwellings at least once in three months with a flea killing mixture made by emulsifying kerosene in water. 6. An efficient daily scavenging of all streets and lanes and the daily removal of refuse from the houses, coupled with the provision of covered metal dust-bins, to reduce as far as possible the amount of food available for rats. 7. The disinfection of plague-infected premises by stripping them and washing them out thoroughly with a kerosene emulsion. The bedding, clothing, carpets, rugs, etc., are conveyed in a huge covered basket to the disinfecting plant and sterilized with superheated steam. No objection is made to the treatment of plague cases in native hospitals, and no restrictions are imposed in regard to the burial of those dead with plague except the provision of a substantial coffin. 8. Every effort is made by means of lectures, addresses and explanations to induce the native population to participate in the above preventive measures. Upon my last visit to Hong Kong, in July last, plague was abating. _The South China Morning Post_ of July 15, 1914, contained the following statement: Plague is gradually disappearing from Hongkong. Last week's return shows that there were 26 cases, of which 19 were fatal. All were Chinese. The total number of cases for the current year to date is 2093, with 1939 deaths resulting.
