During the year, in accordance with our obligations under the Act, two such treatments were undertaken, the first in March and the second in September, 1950. With the completion of additional length of sewers required for the new housing estates in the Urban Area, the total number of manholes increased from 772 to over 810. The location and number of manholes from which complete takes are recorded varies in each treatment. Various factors can be responsible for this, the season as regards breeding, the type of prevailing weather (during very wet weather quite a number of manholes cannot be baited) and of course the effect of mining subsidence upon the sewers. Complete takes are where the number of rats are such that all the pre-bait deposited in a'manhole is consumed by the rats before the next pre-bait or poison bait is placed in the manhole. I understand that the number of bodies of rats removed from the sewers at the Sewage Disposal Works during the period of treatment is often very large and quite impressive. On occasions at least 50 to 90 bodies are removed at one time. 12th Maintenance Treatment completed March, 1950. Section No. of Man¬ holes No. not baited No. baited lv. Pre-ba it Takes C. P.
