Dear Sir,— Believing you to be interested in the economical 

 cultivation and production of India Rubber, we take the liberty of 

 laying before you a few of the advantages that may be obtained by 

 the use of our Rubber Washing and Rubber Rolling Machines. 



As you are probably aware, we were the first to take up the 

 manufacture of a special machine for the treatment of freshly coa- 

 gulated latex, and in July, 1905, we exhibited an experimental 

 machine at the Agri-Horticultural Show held in Kuala Lumpur. 



The machine was shown doing actual work and producing crepe 

 rubber from latex, kindly provided by many local planters. 



The very great success of the machine and high enconiums 

 expressed by Mr. P. Burgess, the Straits Government Analyst, on 

 the excellent results of using such a machine in purifying the rub- 

 ber, induced us to go further into the matter. 



We were fortunate in obtaining orders for six machines during 

 the three days the Show was open, and we then re-designed our 

 machine and placed on the market our now well known 1904 

 Pattern. 



Since then experience has taught us many little detailed improve- 

 ments and we are now suyplying our 1905 Pattern Washing 

 Machine and also a Rolling Machine of almost identical design; the 

 only difference between the two being that the Rolling Machine has 

 smooth rollers and is geared to a 1 : 1 ratio instead of the fluted 

 rollers and i| : 1 ratio of the Washer. 



The advantages of using our Machines for the production of 

 marketable rubber are many and various, and the more important 

 points are briefly enumerated below : — 



(1) The action of the rollers on the freshly coagulated latex is to 

 entirely remove all albumen, and other impurities which remain in 

 the rubber (to its consequent detriment) if made into biscuits. 



(2) The crepe after being treated on the two machines has a 

 close, fine, even texture and is extremely thin, and can thus be 

 dried, without the aid of an artificial drying house, in about^ three 

 days, and is considerably easier to pack for shipment than in the 

 biscuit form. 



(3) The machines working together will treat at the very least 

 one hundred pounds of dried rubber per hour or singly fifty pounds 

 per hour, and each machine requires from five to eight brake horse 

 power to drive it ; only one man is required to feed a machine and 

 the saving effected over the handmade biscuit process is obvious. 



(4) By the manufacture of crepe rubber the disadvantages of 

 having a large number of coagulating dishes and trays are obviated 

 as the latex is all poured into one large receptacle and there
