Habitat and Sylvicultural Notes. 
Camphor is always found growing on low steep hills or on the 
lower slopes of high hills. I should say that 800 feet above sea level 
would be its limit. I have never seen it on low-lying flat ground. 
In the places where it is found it forms at least 50 % of the grow- 
ing stock, all age classes are usually represented, though, as is 
generally found in evergreen virgin jungle, the mature trees out- 
number the younger age classes. 
I have seen places where there were no intermediate age classes 
between the mature tree and a fine crop of young natural re- 
generation. 
Camphor I would class as a ‘ light demander ’ and as the tree is 
usually associated with B^rtam undergrowth many of the seedlings 
do not get a chance of surviving. 
Under proper treatment I have no doubt that natural regeneration 
would yield a very full crop of seedlings. 
An attempt to transplant seedlings to a different place in the 
jungle met with no success, but I did not see this operation performed 
myself. In the Rompin district improvement clearings in favour of 
Camphor have been carried out and the young freed seedlings had 
put out a leading shoot up to 2' in length in 8 months.

Timber . — The primary use of the Camphor tree is for its timber. 
From measurements extending over a few years it has been 
calculated that a Camphor tree will reach a girth of 6 feet in 100 
years. The timber will float and if the Rompin district was opened 
up by roads an export trade up to 30,000 tons of timber per annum 
would be possible, allowing for the forests being managed under a 
proper system of sustained yields. 
I might mention here that the Forest Department have reserved 
2,000 acres and that a further 60, 000 acres is being demarcated this 
year, containing at least two mature trees per acre. 
Camphor . — The Camphor which is obtained from the tree is 
known to the Malays by the name of ‘Isi Kapur.’ From enquiries 
made it appears that about one tree in every 200 trees, both big and 
small, has this ‘ isi ’ and the amount obtained varies from a few ounces 
to three catties. The method of extracting the Camphor is to split up 
the wood and pick the crystals out of small cavities which are found. 
I have also heard of it being found in the stumps of dead trees. 
In connection with this ‘isi’ there is a superstition that if the 
men who are looking for ‘isi ’ do not talk a peculiar language while 
on the search, they will have no luck. I was unable to pick up any
