PARA RUBBER. 11 



considered to be near the maximum and a rainfall of 70 inches near 

 the minimum for the cultivation of this species. There are trees, 

 planted in 1899, measuring 18 to 26 inches in girth and 22 to 33 

 feet in height, growing on Weweltalawa, Halgolle estate, on the 

 borders of the Kelani Valley and Yakdessa districts, at an eleva- 

 tion of 3,300 feet. It is being tried in districts having 200 inches 

 of rain per year and also in dry irrigable areas, but reliable results 

 cannot be obtained for many years. 



The following are the meteorological details of places in particular 

 districts in Ceylon where Para rubber trees are being successfully 

 grown (Surveyor-General's Report, 1902 and by letter) : — ■ 



In the Colombo, Galle, Ratnapura, Kelani, and Kalutara Dis- 

 tricts the rains in the N.-E. and S.-W. monsoons are very heavy; in 

 the Kurunegala, Matale, Badulla, and Passara Districts they are 

 less violent, but in all the districts mentioned above, rain falls 

 every month in the year, the monthly variation being from about 

 five to twenty-four inches. 



The Climate in the Federated Malay States. 



In the Federated Malay States there is no evidence of the 

 highest elevation at which Para rubber will thrive, though some 

 young trees are growing at Gunong Angsi at an elevation of 2.5(H) 

 feet. According to Carruthers the growth of Para rubber from 

 sea-level up to 300 feet in the Federated Malay States is better 

 than that at most places.
