120. Several deep pools in the rocks were filled up with stones and soil, grass was induced to grow on them, other shallow pools were filled up with cement by the Dairy Farm Staff. Very little damage was done to this work by the rains. Breeding places in Pokfulam village which were causing a mosquito nuisance were also dealt with. A great improvement resulted.

121. Complaints having been received from the European residents of the seaside resort of Shek O of a plague of mosquitoes investigations were carried out in the neighbourhood. The mosquitoes causing the nuisance were C. fatigans, A (F) togoi, C. sitiens and A (S) albo pictus.
122. C. fatigans was found breeding in septic tanks, and in the sumps connected with houses and pigsties in the native village. A. albopictus larvae were found in abundance in water collected in tins and bottles near the bungalows. C. sitiens bred in collections of water in old boats. A. togoi larvae swarmed in rock pools close to the sea shore and on an island close by.
123. Anti-malarial and anti-mosquito work were commenced on 16th July by the Assistant to Malariologist. Two coolies, oiling mixture and tools were supplied by the Sanitary Department, two coolies and two sprayers by the Shek O Club.
124. The septic tanks were oiled, and the sumps emptied weekly by the villagers. A. (F) togoi bred in rock pools by the sea, some of these were filled up with stones and soil, others oiled. A. (S) albopictus larvae were found in abundance in a miscellaneous collection of tins and bottles in the bungalow compounds, these were dealt with; also old disused boats on the beach which had filled with water, and were breeding C. sitiens.
125. No difficulty was experienced in securing the necessary help and co-operation from the villagers. As at Waterfall Bay, practical demonstrations of the development of mosquitoes from larvae and pupae were given.
126. The swampy ravines around the Shek O Club were ditched and drained, unnecessary ditches were filled in, streams were cleared for oiling. It was decided to leave the steep portions of the streams alone, as hitherto A. minimus larvae have not been met with in numbers in such places.
127. Unfortunately the main drainage is obstructed by a sand bar near New Shek O Village. The building of a groyne, or drainage by a culvert with tidal flap, appears to be the
