In Hong Kong, as in many other parts of the world, there appears to be a general belief that the cutting of undergrowth and the clearance of bush in some way brings about a diminution in the number of mosquitoes especially the species which carry malaria. Whatever may be the effect on culicines it is a fact that the very potent malaria carriers, Anopheles maculatus and Anopheles minimus breed in water open to the light and shun that shaded by trees or undergrowth. Clearance of bush may, therefore, result in an increase of malaria rather than in a diminution.
Sanitary Inspectors. During the year the Sanitary Inspectors continued their routine visits of inspection. Under their supervision come the domestic houses, common lodging houses, places of common assembly, eating houses, bakeries, etc., etc. As mentioned previously there are approximately 30,000 people per Inspector—and it is physically impossible for any man to carry out the number of inspections necessary to secure a proper standard of sanitation under the conditions prevailing in this Colony.
