youth of a tree is its most important period of life. The young 
plant is unbranched and has formed only a few buds to take the place 
of any injured. Its leaf area is small and on its leaf area depends 
its root growth. Any weakening of the seedling is apt to cause 
weakness in the adult, slow growth and poor development. 
It is therefore advisable to see that the nursery beds are not over- 
crowded, and that the plants are free from mites. Perhaps the best 
treatment for these is the old one of flowers of sulphur. The finely 
powdered sulphur is put in a bag of cloth of not too thick texture and 
this is tie I to the end of a stick. Holding this in one hand among 
the seedilings, it is beaten with a switch so that the fine sulphur dust 
flies on the breeze through the bed beneath the leaves.

MALAY CAMPHOR. 
By A. Sanger Davies. 
Dryobalanops C amphora, known to the Malays as ‘Kayu Kapur.’ 
General Appearance. 
A very large evergreen tree attaining a height of 150 feet and a 
girth up to 35 feet. In the smaller girths the tree is not buttressed 
* but when it attains a girth of 5 feet it puts out fairly strong buttresses. 
In places where this tree is found it towers above the surrounding 
jungle and may be recognized miles off by its greyish looking foliage 
and the shape of its crown, which is best described as being like an 
umbrella. 
The branches are small for the size of the tree. Bark I in. to 2 ins. 
thick, greyish brown, uneven, in older aged trees peeling off in large 
flakes. When the tree flowers in September, the whole jungle pre- 
sents the appearance of having been through a snowstorm, even the 
rivers carry away thousands of fallen blossoms.

Distribution in Pahang. 
Ihe Camphor tree is found growing along all the lower slopes of 
the dividing range between the Rompin and Endau watersheds. It 
is also found to a small extent on low hills lying to the North of the 
Rompin river. 
In the Kuantan district it is found on the slopes of the Bukit Sar 
range which forms the dividing line between the Jabboh, a branch of 
the Kemaman river and the Baloh river which flows into the sea some 
10 miles north of Kwala Kuantan, but the area here is not of much 
account. In the Rompin district I would estimate that the total 
area containing Camphor is not far short of 200,000 acres.
