12 PARA RUBBER. 



According to the Manual of Statistics published by the Federated 

 Malay States Government " the climate of the Federated Malay 

 States is very uniform and can be described in general terms as 

 hot and moist. The annual rainfall, except in places close to the 

 mountain ranges, is about 90 inches. In towns, such as Taiping, 

 Tapah, Selama, &c, close to high mountains, upwards of 50 per cent, 

 more is registered, the average of ten years' records at the first-named 

 being 164 inches. There is no well-marked dry season. Generally 

 speaking July is the driest month, but has seldom a less rainfall 

 than 3| inches. The wettest season is from October to Decem- 

 ber, and there is another wet season of slightly less degree during 

 March and April. Rain rarely falls before 11 a.m., so that 

 hours of outdoor work can generally be depended upon all the 

 year round. 



The average maximum temperature, occurring between noon and 

 3 p.m., is in the low-country just under 90°, and the average mini- 

 mum occurring before sunrise is just over 70°. The general mean 

 temperature is about 80°. There is very little change in the mean 

 monthly temperature during the year, the average of ten years' 

 readings in Taiping exhibiting a difference of only 3° 2 between 

 the mean temperature of May, the hottest, and of Decem- 

 ber, the coldest, month of the year. 



The variation of temperature with altitude may be taken roughly 

 as a decrease of 3° for every 1,0'JO feet increase of altitude."
