bearing I believe that it is not likely that the system will be found 
anything but useful when it comes to tapping or picking, whether 
on days wagqs or contract. 
As will be seen from the sketch everyone of the blocks has its 
name; so for instance, there can be no mistake possible when I say that 
the stream running through fields E/2, D/2 and D/i has its spring 
in the jungle at E/3 and it is impossible to miss a hill lying in G/5, 
In the same way as every square can be accurately designated it 
is also possible to name every individual tree within one of the 10- 
acre blocks which, with the 50 trees in every direction represents 
a fixed spot in a similar though smaller co-ordinate system.

TRANSMISSION OF RUBBER SEEDS. 
We have received the following letter from Mr. Bartlett of the 
Botanic Gardens, Demerara, as to a sending of seed of Para rubber 
from the Botanic Gardens I am much obliged to you for the 
three boxes containing 1,200 seed I am glad to say that over 920 
of the number have grown into plants and a few more are still 
appearing which I regard as very satisfactory, considering the length 
of time that they were on the voyage. Theydid not arrive here 
till nearly the end of October, i.e., about two months after they were 
dispatched. 
Transmission by parcels post would appear in spite of its costli- 
ness to be far the most economical way of sending Para rubber 
seeds for a distance, for out of another lot, of 12,000 obtained by a 
private grower here from Ceylon and sent in boxes of powdered 
charcoal not one plant has been raised.”

CHENGEI DAMAR. 
We see by the Malay Mail , that Messrs. Lanham and Shaw 
HlLLIER intend to start a Damar Industry in the Raub district. 
The damar is to be obtained by tapping the "Chengal” tree 
Balanocarpus maximus. 
This tree also known as Chengei and Penak, gives a beautiful 
transparent damar, of good quality for which there is some demand. 
This is perhaps the first European attempt to w r ork the damar from 
the tree directly. One would like to know details of the methods 
adopted for obtaining it.
