EXAMINATION OF RATS.
The results are given in Table I. The total number of rats examined was 85,402 as compared with 86,114 in 1917. 186 were found to be plague-infected (23 in 1917).
BACTERIOLOGICAL EXAMINATION OF Water.
The three chief water supplies of the Colony (Kowloon, Tytam, and Pokfulum) were examined quarterly and the results are given in Tables II, III, and IV.
In every case the sample was taken at its source, i.e., either directly before or directly after filtration.
The methods used in carrying out the examinations were the same as those described in my "Report on an Investigation of the Pokfulum Water Supply" (No.20 of 1911).
