111 other districts where the rubber has been planted in very 

 poor tea and cacao land the growth is often very slow. 



The Neboda Tea Co., in their annual report for 1905, state 

 that the 1904 clearings range from 17 to 27| feet in height and 

 from 6 to 10 inches in circumference, while last year's basket plants, 

 put out in April- May, from August, 1904, seed, show the best 

 growth : 8f to 12J feet in height and 3-| to 4J inches in girth. 



Under suitable conditions of soil and climate in Ceylon, one must 

 allow for the full development of the plant and a spread of branch 

 diameter of at least 30 feet for trees 10 years old, and 40 feet for 20- 

 year-old trees might form the basis of calculations where pruning is 

 not adopted, and where the cultivation is intended to be permanent. 



The diameters of the branch and foliar system of trees of known 

 ages measured on rubber property in Ceylon are here given , but it 

 must be understood that the growth has been obtained where Para 

 rubber is interplanted with cacao or tea. The growth is very variable. 

 The Para stumps were from one to two years old when planted.
