A. hyrcanus, and only 11 A. jeyporiensis. So far, larvae of A. jeyporiensis have only been found in pools in rice stubble soon after reaping of the second crop.
170. In order to reduce the A. jeyporiensis catch in October and November, drying off of the rice fields on one day of each week from the end of September, should give good results. This measure has been legally imposed in Java. Owing to the density of the growth of the rice at that time, it is difficult to understand how Paris Green could be usefully employed.
171. The Malariologist paid 42 visits during the year, the Assistant to Malariologist 4; four Inspectors made 72, 74, 22, and 19 visits respectively. In addition, two Vaccinators paid 35 and 8 visits and two Laboratory coolies 2 visits each.
172. The visits were made for the purposes of larval surveying, searching for new breeding places, checking of oiling measures, inspecting fallow rice fields which had been drained to ensure that the drainage was being upkept, checking local Anopheline catches, inspecting areas dealt with by engineering works.
173. The Anti-Malarial and Hospital Staff were housed in mosquito-proofed quarters, none of them contracted malaria.
174. Twenty-six Europeans resided in mosquito-proofed quarters; no cases of malaria were reported.
175. A Police force, eight in number, resided at Shing Mun in mosquito-proofed quarters. No hospital admissions for malaria or other disease were recorded.
176. Table XVI gives the estimated population of the Labour Force, month by month, its distribution according to race, the number of cases treated due to malaria and to all causes, also the results of examinations of blood films for malaria. The figures have been supplied by the Resident Medical Officer.
177. The malaria case rate was low in February, March, April, May, rose to 70.9 per 1,000 in July, declined somewhat during August, September, October, and rose to 102.1 in November. Some infections were contracted at the Camp, others at places outside the controlled area by a fluctuating labour force residing in malarious villages such as Wo Li Hop, Tsun Wan, Sheung Kwai Chung, but working at the Dam, a great number of cases must have been due to relapses owing to treatment in the lines of the majority as there was not sufficient accommodation in the hospital on account of the large increase in the labour force.
