RECEPTION OF LATEX AT THE STORE.--Bearing in mind the remarks in Chapter
VI. on the conditions under which latex is transported, it follows that
nothing but the very best and most suitable vessels should be used in the
store. A point to which adequate attention is not given in many factories
might be mentioned here. Considering the importance attached to colour in
the dry rubber by brokers and consumers, and knowing how extremely trivial
are the causes which may mar the colour, it is rather surprising that
better provision is not made for the reception and handling of latex in
factories. Too often the receiving vessels are placed on the floor of the
store close to the entrance. Coolies bringing in latex cannot avoid
bringing with them quite a considerable amount of dirt. Presuming that a
hose-pipe has been installed, and that the floor is constantly being
sluiced down with water, no great harm will result. But would it not be
ever so much better if the dirt were kept out? In how many factories is
provision made for this? Such an arrangement is not difficult to make, and
is already in practice on a few estates. A verandah is built outside the
wall of the factory and all latex is received there. In another place open
chutes are provided which terminate in the straining sieves. The coolie
thus stands on the verandah where he removes coagulated lump and impurities
from the latex, which is then poured down the chute, passing through the
sieve into large coagulating jars or tanks.
Too often it would appear, from the writers' observation, there is a lack
of adequate supervision on the arrival of latex at the store. Much can be
learned from an inspection of the coolies' buckets, and the cause of small
defects in the finished rubber can often be thus traced. Leaves, stems,
bark-shavings, and dirt appear in the buckets, and it is a source of
constant surprise to imagine how even unintelligent coolies can allow such
things to happen. These objects are removed before or during straining, but
still they ought not to be there in the first place, and the fact that such
a state of things exists is evidence of neglect on the part of the coolies
or lack of supervision. Efforts are made in a large number of cases to cope
with these troubles, but on some estates things are allowed to proceed in
the same slipshod way, and too much responsibility is thrown on the
straining process.

It is suggested that it should be the business of a European to supervise
the reception of latex every day. This is at present quite impossible on
some estates, but it does not alter the fact that this supervision should
be provided, and is extremely necessary.
