140. Flowing south from Tai Mo Shan is a large stream “A” with numerous branches which lie on all sides of the Camp. The streams are rocky bedded and boulder strewn, the boulders being of all sizes and shapes. In places the grade of the streams is steep, in other places flat. Sometimes the course leads through deep gorges. In some of the valleys rice fields arranged in terraces have been constructed by building a series of stone walls across the valleys in order to retain the soil, the stream which had flowed through the valley being usually diverted to one side and used as an irrigation channel. In other instances the water for irrigation is derived from seepages which drain into ditches.
141. Since 1933 anti-larval measures had been completed over the whole area within half a mile of the Camp. This protected area had been extended along valley A.5 up to the access road. Works of a permanent nature were carried out within the quarter mile radius. In the rocky bedded streams “C”, “D”, and “E” drainage pipes and rubble were placed. Engineering work was also done on that portion of the ravine which runs between Pineapple Pass and the village of Wo Li Hop and in the A. jeyporiensis breeding places lying along the Shing Mun and its tributaries between Pineapple Pass and the P.W.D. dam.
142. The remaining streams and rice fields within the half mile circle were dealt with by temporary measures by the Bureau's staff. Streams were cleared and water oiled. Rice fields fallow and flooded in which A. jeyporiensis were breeding in enormous numbers were dried by ditching and the ditches oiled.
143. The nearest human habitations to the Camp is the village of Wo Li Hop which is half a mile distant as the crow flies.
144. There are no human habitations in the upper reaches of the Shing Mun the villagers having migrated. The rice fields which formerly existed in most of the secondary valleys between Pineapple Pass and the abandoned village of Ho Pui became grass grown swamps where A. jeyporiensis bred in large numbers until drainage operations rendered them unsuitable for the purpose.
145. Since 1934 measures directed against A. jeyporiensis had been taken in the Shing Mun valley extending from Pineapple Pass to Po Hui village, and in the valleys of the upper tributaries of “A” lying to the north of the access road, and reaching westwards to the headwaters of stream “B”.
