“nerve,” “fibre,” “pull,” “strength,” or whatever other 
terms may be used for the possessions of elasticity and 
resilience to a high degree. If this character of Malayan 
plantation rubber is continued and improved, there is no 
reason to doubt that the manufacturer will in a short time 
begin to set a value on it equal and perhaps better than that 
given to the wild Para of Brazil. 
The exclusion of all latex which may contain too much 
vi seine, resin, etc., since it is obtained from young trees, 
when “bulking” latex is strongly to be recommended; there 
is always a market for poorer values of rubber by them- 
selves, and the inclusion of a small quantity of inferior latex 
may considerably reduce the value of the whole break, and 
at the same time do harm to the good name of the estate for 
sound rubber. 
Block rubber has great advantages over the other 
forms, in that it is less bulky and costly for storage and 
transport, less liable to any damage by damp or heat in 
transit. Many leading manufacturers and technical ex- 
perts in Europe consider that the block rubber possesses 
more of the desirable qualities of the Brazilian Para than 
crepe or sheet; and the only objection which any of them 
make to block is the fact that it cannot always be* examined 
for interna! impurities without cutting each block. This 
drawback is obviated if the blocks are made only 1 to H 
inches thick, when they are transparent and any opaque 
object included in them can be defected by holding them 
up to th '2 light. 
fk beer Seed. 
The question of tl^ sale of rubber seed for oil purposes 
should be ca\refully considered by every careful planter. 
The crop of °ed ir the Peninsula was probably not less 
than 300,000 ^ 1,200 tons in weight, valued to the 
London mark over $100,000. This amount of available 
seed will increase annually very rapidly, and in five years 
time more than 3( } times this will be produced . The follow- 
ing figures show that there is a fair profit for the collection 
and export of tl* e se seeds, even at the rates which are at 
present offered for decorticated seed, and it is not impro- 
bable that whe a sufficient quantity is placed on the market 
a higher price will be obtained.
