117. The average monthly population of the lines were given as follows:
Road contractor coolie lines 110
Works and building coolie lines 70
Nullah contractor coolie lines 100
118. On the 9th July the Acting Malariologist was informed by a foreman at Patheung that there had been a number of cases of malaria amongst his workers. On the 24th July the Acting Malariologist reported the occurrence of 90 cases of malaria in 10 days, and the catching of 64 A. minimus in the Shek Kong matsheds.
119. Arrangements were made for the appointment of a Resident Dresser for the treatment of the sick, and for the co-operation of the M. O. i/c New Territories with the same object. An Anti Malaria Inspector was appointed and a gang of 12 coolies engaged for anti-malaria work. The Inspector assumed duty on 19th August.
120. From 4th August to 9th December, the Assistant to Malariologist visited daily (holidays excepted) and superintended the anti-malarial operations. Streams and ditches were cleared of obstacles and oiled, special attention being paid to places where larvae of A. minimus had been found; rice fields were drained after cutting of the second crop.
121. There is no proper control over the area in which anti-malarial operations are required and until this has been effected, good results cannot be expected.
122. During the period July to December, 734 blood films taken from the labour force were sent in by the M. O. i/c Un Long Dispensary to the Bureau for examination; 433 contained parasites.
123. Several morning catches were done in the coolie lines, and in Shek Kong village houses inhabited by coolies. In the nullah contractor's lines 490 A. minimus, 107 A. jeyporiensis, 1754 A. hyrcanus were caught in 63 morning searches.
124. In 24 mornings, in the matsheds near Shek Kong, only 4 A. minimus, 1 A. jeyporiensis were taken. In the Shek Kong houses, 69 A. minimus were taken in 24 mornings.
125. During the year 39 larval surveys were made in the streams and ditches; 362 A. minimus, 1 A. jeyporiensis, 81 A. maculatus, 1,258 A. hyrcanus were collected. A. minimus larvae were also met with in scanty numbers (considering the time spent in the surveys) in 1935.
