The following extracts are taken from Notes on Rubber Growing 
in Perak by Mr. L. Wray, Curator and State Geologist, Perak, 
dated 4th December, 1897 :— 
In 1887 some seed was obtained from the Kuala Kangsar trees 
and planted in the Museum grounds, Taiping e soil is very 
bad, the land having all been mined over, but still the trees have 
grown well and have attained, in the ten Sg which have elapsed 
since they were planted, a considerable siz 
The tree has also been planted at Parit Bhd where it grows 
well. It is in the garden of the District Magistrate, and close to 
the river. The land is occasionally flooded by the river, and in 
the ordinary way 2t high tide the river is only a foot or two 
below the level of the surface of the gro ound. The river is quite

State, and in all it has grown well. 
It may therefore be stated that it will thrive in any locality, 
from the bakau swamps to the foot-hills, and on any soil, from 
rich alluvial to old mine heaps.

serious injury. When large areas come to be planted up there 
may arise trouble with some pest, but at estu there does not 
appear to be any indication of such a contingen

To be a success—that is, to yield large brafierwie of rubber 
the tree must be qnie so that it will run up and form a tall, 
straight, branchless trunk. 
ssa is little to quide one on the subject, but from 15 to " 
eet apart would appear to be about the correct spacing..
