As the map indicates the village is situated north of the access road to the Shing Mun Camp, on the hilly ground sloping from Tai Mo Shan ridge seawards. It is over half a mile from the Shing Mun Camp; south of the village and on either side of it are terraced rice fields. Several hill streams flow down from the ridge. Along the banks of the Shing Mun river above Pineapple Pass there are fallow rice fields, some of which were flooded and favourite breeding places of A. jeyporiensis. There are also fallow rice fields along the banks of stream B north of the access road.
In 1932 about 160 coolies engaged on making the access road to the Dam were housed in matsheds situated by the roadside opposite the hamlet. These suffered severely from malaria. In December 1932 fifteen village children between the ages of 2 and 10 were examined, five had enlarged spleens or 33%.
Catching was done as a rule once a week except in the month of May. During January, February, and March catching was also done in the matsheds accommodating the road-making coolies. The matsheds were afterwards demolished when the coolies left.
The Inspectors when collecting took thick and thin films from any sick persons encountered in the village. The results are shown in Table XX.
Towards the end of the year some coolies (employed at Shing Mun) and their families were residing in the village and contributed to most of the cases of malaria. Only one of these used a mosquito net, but practically all of the villagers used nets. If malarial parasites were found, it was reported to the Medical Officer in charge New Territories for treatment by the Travelling Dispensary.
The results of the catches are shown in Table XVIII and the dissections for malaria in Table XIX.
The majority of the Anophelines captured were A. jeyporiensis.
The malaria infection rate was low in the first quarter, rose towards the end of the second, continued high in the third and declined in the fourth but the infection rates were low compared with those found in the Shing Mun Camp dissections in the corresponding months. Gland infections were found in every month; the infection rates of A. minimus and A. jeyporiensis differed widely in certain months but approximated in the total dissections.
