(8) Taikoo Sanatorium.
126. In December 1932, 16 larvae of A. maculatus and 19 of A. minimus were found in a brick and cement tank, 6 feet square, near the site of the former Taikoo Sanatorium. The tank was fed by a seepage trickling from the rocks, and overflowed into a concrete channel. The site is approximately 1200 feet above sea level, one mile as the crow flies from the nearest habitation. No one had been living there since 1930. During 1933 the tank was inspected monthly excepting the months of February, May, September. No Anopheline larvae were collected until November when 28 A. maculatus were found. In December 15 A. maculatus and 1 larva of A. minimus were collected. In 1934 monthly collections were made except during the months January, February, June, July; but only larvae of C. bitaeniorhynchus were found.
(9) Tai Hang Road Matsheds.
127. Mosquito catches were made once a month in the first half of the year and more often in the second half. The matsheds were sited close to Tai Hang, an eastern suburb of Victoria. One set was situated on the spur above the road, overlooking the untrained portion of the Tai Hang nullah. In these, catching took place on 24 mornings. No Anophelines were caught. Another set of matsheds were situated in the nullah, by the roadside. In 19 morning searches, 4 A. minimus were obtained, 2 in September, 2 in December. None were found infected. No labourers were found sick in either set of lines during the visits although about 102 were employed.
128. The untrained portion of the nullah between Tai Hang Road and Sir Cecil's Ride was surveyed monthly; larvae of A. maculatus were found and occasionally a few A. hyrcanus.
(10) Tung Wah Matsheds.
129. These were occupied by contractor's labourers, about 44 in number, who were engaged in the training of a nullah between Tai Hang Road and Sir Cecil's Ride. By the end of the year the training was almost completed. Visits once a month were made during the period January-June; after that, more frequent visits were made. In 24 morning searches 4 Anophelines were captured, two being A. minimus, the other two being A. jeyporiensis; three of these were captured in January, one in March. No sick were found in the lines.
(11) Wong Nei Chong Village.
130. This hamlet is situated near Blue Pool Road, south-east of Happy Valley. Mosquito catching was done on 19 mornings, monthly visits being made during the period January-June. No Anophelines were taken, but C. fatigans figured largely in the
