NUMBER OF TREES PER ACRE. 



The following figures give an idea of the average 

 distances for Hevea, which are usual in the Malay 

 Peninsula. 



Malay Peninsula. 

 (F. M. S. & S. S.) 



Planted surface Number of Planted 

 in acre?. Trees. 



1906. 123,463 12,325,904 



1907. I79>227 27,558,440 



1908. 241,138 37,440,200 



In 1907, the average number of trees per acre was 

 therefore, 153, which is equal to a distance of 17 X 17; 

 in 1908, it was 163, or 16 X 16 feet. In 1906 1/3 f 

 the total plantations in the Malay Peninsula exceeded 

 200 trees per acre, that is, less than 15 V 15 feet; 

 whereas 1/7 consisted of plantations, the distance of which 

 amounted to 18 ( 18 feet. The average for that year 

 was 1 68 trees per acre, as a maximum. 



Experience has taught us that we should not plant 

 closer than 15 X 15 feet. If the planting distance is less, 

 the plantations are backward and even after thinning, 

 they are small in diameter, compared with plantations 

 which had been originally made at a wider distance 

 and they will never make up the difference. A wider 

 planting distance than 15X15 feet will be advisable in 

 cases where catch crops are cultivated.
