(d) Anti-malarial work was undertaken round the Volunteer Camp at Fanling from October to December.
(e) Permanent anti-malarial drainage was carried out by the Public Works Department by the training of 2,160 feet of stream channels at Queen Mary Hospital site, the channels varying in size from 45′′ to 12′′ in diameter. The total expenditure was $17,580.00.
(f) An experimental "Ceylon Flushing Syphon" was installed by the Public Works Department at Mount Cameron. This tank worked satisfactorily during the dry season and enabled the "De Villiers" tank, constructed the previous year, to function normally throughout the winter.
(g) Tables are appended of work of an entomological nature undertaken by the Bureau during the year. From March to December, 4,496 fleas were examined at the Bureau. Of these, 89.13% were Xenopoylla cheopis; 9.99% Leptopsylla segnis and 0.88% Ctenocephalus felis. There was little monthly variation in the cheopis percentage, but from the tables, it would appear that the rats appear to be more heavily infested in the damper months of April, May and June.
A fly nuisance was investigated during the year at the Queen Mary Hospital. 2,404 flies caught at the Hospital were identified at the Bureau. Investigations round the hospital proved that the large proportion of Musca domestica were undoubtedly breeding in the manure used in the cultivation of grass at the Dairy Farm. Recommendations in regard to the destruction of Musca larvae in the manure produced a drop in the figures in July, and it is hoped that this, combined with tidier methods of cultivation will completely eradicate the nuisance in 1940.
286. Mosquito nuisances were investigated at:
(a) Barker Road, (b) Mount Cameron Road, (c) The Peak, (d) Leighton Hill, (e) North Point, (f) Shaukiwan, (g) Repulse Bay, (h) Queen Mary Hospital, (i) Kowloon Tong, (j) Prince Edward Road, (k) Argyle Street, (l) Ho Man Tin, (m) Water Police Station, (Tsim Sha Tsui), (n) Railway Quarters (Hunghom).
287. Teaching of Mosquitology.
(a) Demonstrations in collecting mosquito larvae and adults and instruction in the elements of malaria prevention were given to two classes of Royal Army Medical Corps men. Captain Curran, R.A.M.C., engaged in anti-malarial work for the Army made use of the resources of the laboratory, and the knowledge and experience of the staff were placed at his disposal.
(b) Lectures and demonstrations were given to Teachers Association at King's College.
(c) Lectures to probationer sanitary inspectors on mosquitology and prevention of malaria were delivered, and demonstrations on field work given.
(d) Lectures on mosquito prevention were given at schools in the Kowloon City and at Kam Tin.
(e) Material for the teaching of mosquitology was supplied to the R.A.M.C. College, Millbank, the Lester Institute, Shanghai, the Lingnan University and the Peiping University.
