if any, and thus ascertain if there be any connection between 
their occurrence and our rainfall; and the Principal Civil 
Medical Officer would also help considerably if he could see 
his way to having rain gauges and reyvisters kept at Changi 
or Siranggong (extreme east), Tanjong Karang (west), at 
the Police stations, Bukit Timah Road 7th mile, and Seli- 
tar; a more general average of the rainfall could thus be 
ascertained. The absence of astation or stations well in 
the centre of the island is a drawback, the more so as many 
of the streams running into the impounding reservoir, which 
supplies the town with its drinking water, are fed by the 
rains falling on the southern aspect of Bukit Timah. There 
should be little difficulty in teaching the Police Sergeants 
in charge of the stations to keep the register.
