Antimalaria drainage, both , by open channels and 
by underground pipes, has in this country reached a. 
high grade of perfection and there are many localities 
where such drainage has had marked beneficial results. 
The railway town of Gemas which two years ago was 
a hot bed of malaria, is now a healthy station and a 
saving of $50,000 a year has been effected. 
Singapore, Kuala Lumpur, Seremban, Taiping, 
Klang and Port Swettenham are all cases of successful 
ahtimalarial drainage- In Kuala Lumpur town there 
are 130 itiiles of subsoil drain. 
Dysentery and Diarrhoea. 
Dysentery and diarrhoea rank next to, but far 
behind, malaria as a cause of death. As the rates in 
urban districts supplied with filtered pipe water are 
higher than the rates for the whole country it is clear 
that the drinking water supply is not the only factor 
involved. Probably contamination of food supply is 
the chief cause. In the towns the majority of people 
live in cubicles under conditions which necessitate 
them purchasing food prepared, cooked and ready for 
eating. Laws and regulations aimed at securing clean 
food supplies' are in force but no law can obviate all 
the risks involved in the consumption of foods prepared 
by -people who do not understand what are possible 
sources of contamination and who would not bother 
if they did. 
Compared with many tropical countries Malaya is 
not fly infected but the house fly is no stranger and, 
especially in towns, is too much in evidence.
