APPENDIX * IP 
The interests at stake are so great that I may be permitted per- 
haps to put in condensed form the advantages of the use of a 
washing machine in preparing rubber: — 
1. The rubber produced will be as pure as it possibly can be 
without costly chemical treatment, 
2. The rubber being pure will be of uniform quality. 
3. The rubber being washed will be ready for immediate use 
by the manufactures, it will therefore have an enhanced 
value from the manufacturers’ point of view, and with 
open competition must command a higher price. 
4. It will effect a saving of labour to the planter by eliminating 
the petty hand labour involved in coagulating rubber in 
small plates, rolling the sheets by hand and manipulation 
of the small biscuits produced. 
5. There will be an enormous saving of time in drying the rub- 
ber, this will involve a saving of storage room and laboui 
in looking after the rubber when drying. 
6 . There will be no possibility of putrefaction of rubber in dry- 
ing or discoloration by the growth of mould, the substances 
which putrefy or which feed mould being eliminated. 
7. The machines will clean and deal efficiently and economi- 
cally with scrap. 
8. Rubber from Ficus elastica can be prepared efficiently and 
economically. 
9. The washed rubber can be turned out of any length or thick- 
ness required, it will be easier to handle and pack. It 
keeps better than the best of the biscuits prepared in the 
old way. 
APPENDIX IIP 
The following objections have been made to the use of a rubber 
washing machine: — 
1. The initial cost is considerable — against this must be ba- 
lanced the direct saving of gear which is recjuired in the 
coagulation and preparation of rubber in the biscuit form, 
and the indirect saving of time and money consequent on 
the advantages of using the machine. 
2. The manufacturers will- not appreciate the rubber in the 
washed state: — 
The answer to this lies in the fact that the manufac- 
v turers themselves turn all the rubber they buy into washed 
sheets, they more than any, know the value of washed 
rubber.
