193. The Association works very closely with the Government Tuberculosis Service and now provides in its two hospitals almost exclusively the facilities for thoracic and orthopaedic surgery required for the treatment of tuberculosis. Admissions to both the medical and surgical beds of the Grantham Hospital and, to a lesser extent, the Ruttonjes Sanatorium are now largely in respect of patients referred by the Government Chest Clinics although both hospitals also arrange admissions direct for their own referred cases.
The Tung Wah Hospitals
194. This group of three hospitals has a varying total of between 250 and 350 beds occupied by patients with tuberculosis. These beds are almost entirely occupied by cases of a chronic type and the turnover is accordingly relatively slow. No special subvention is made to support these beds as the total recurrent expenditure of the group is met by a Government subvention. In the maternity wards of these hospitals the B.C.G. vaccination of new born babies is carried out by the Govern- ment Tuberculosis Service staff.
The Haven of Hope Sanatorium
195. Maintained by the Junk Bay Medical Relief Society this interdenominational Protestant Mission Sanatorium accommodates 210 beds for the medical treatment of tuberculosis. No major surgical or orthopaedic work is undertaken. The Sanatorium staff also maintain a Tuberculosis outpatient and follow up clinic at nearby Rennies Mill and carry out some tuberculosis survey work amongst the villagers in the Junk Bay area. Government maintains 60 beds in the Sanatorium for the free treatment of New Territories villagers and also gives a small annual grant towards the cost of the X-ray survey work.
Other Voluntary Agencies
196. Mention is made in paragraph 403 of the rehabilitation work carried out by the Lutheran World Federation and in paragraphs 339 to 341 of the work of the Sandy Bay Convalescent Home maintained by the Society for the Relief of Crippled Children. Tuberculosis beds are also provided in the Nethersole Hospital and the Hei Ling Chau Leprosy Settlement, both of which organizations receive subsidies for general medical work.

Private Hospitals and Other Agencies
197. There are 132 beds provided in private hospitals and nursing homes, some of which are classed as charity beds in which treatment is given at low cost or free. There is also a considerable amount of ambulatory chemotherapy given by private practitioners but there is no information at present available either on the numbers of palients under treatment or the results of treatment. Mention has already been made regarding the paucity of notification of tuberculosis by private agencies dealing with the disease.
MALARIA BUREAU
198. The Malaria Bureau, under the direction of the Government Specialist Malariologist, is responsible for all malaria control operations throughout the Colony and, in certain instances, it also undertakes the control of breeding of culicine mosquitoes. Lectures are given on malaria and allied subjects to various groups of health personnel under training and expert advice is offered to the Armed Services, to the Pest Control Unit of the Urban Services Department, to Hei Ling Chau Leprosarium and to Prisons in the New Territories.
Control Operations
199. The important malaria vectors are A. minimus found breeding in certain hill streams, seepages and irrigation ditches leading to rice cultivation and A. jeyporiensis var, candidiensis which breeds in rice cultivation, fallow-rice fields, pools in rice stubble and water flowing through grass, Other anopheline species found in the Colony play little or no part in malaria transmission. Malaria control in the urban areas is based chiefly on anti-larval measures consisting of training and clean- weeding of streams, ditching and oiling. Anti-malaria oil continues to be employed as the main larvicide, although Gammexane Dispersible Powder is also used on a limited scale in areas where the application of oil is unsuitable. These anti-karval operations against anopheline breeding afford protection to over 21 million people living within the urban areas of Hong Kong, Kowloon and New Kowloon and in certain circumscribed areas in the New Territories.
200. Results of the Malaria control work in the urban areas continue to be satisfactory and the incidence of natural malaria trans- mission has been reduced virtually to zero.
201. In most of the New Territories control by anti-larval or anti- adult measures is at present impracticable because of the scattered
