made anywhere, a cup being used for each incision, and the 

 tapping was done with a small axe and a chisel. This com- 

 plete reversion to primitive methods is a striking illustration 

 of the extent to which modern ideas had then penetrated 

 {T.A., XXII., p. 839, ex " Straits Times," April 16, 1903). In 

 experimental tapping at Singapore in 1904 the cuts were not 

 re-opened (Straits Bulletin, III., p. 340). 



Parkin's acetic acid method of coagulation met with 

 considerable opposition, especially in Malaya. Arden claims 

 that he was the first to introduce it into the Malay Peninsula 

 in 1900 (" Indiarubber Journal," November 1, 1913). Curtis 

 tried it in Penang in 1901. But the process was considered 

 unnecessary and impracticable in Singapore, and it does not 

 appear to have been adopted there until 1903 (Straits Bulletin, 

 II., p. 44). Ridley (Report, Singapore, 1900) stated that the 

 addition of creosote made the rubber sticky. 



In Cejdon the method of re -opening the cut is said to have 

 been adopted in Kalutara in or about 1900. But it did not 

 meet with universal approval. F. Holloway (Kepitigalla) 

 described his method of tapping, &c., in the " Indiarubber 

 World " in 1903 (see T. A., XXII., p. 726) ; single V incisions 

 were used, five V's in a ring round the stem, every alternate 

 day, until twenty such rings had been made. He gave a 

 figure of the well-known tapping knife with a triangular box 

 head, made by the Eastern Produce and Estates Co. 



XIII.—" Ceylon " Rubber. 



For many years it has been customary, more especially in 

 America, to style all plantation rubber, " Ceylon " rubber, 

 even such well-known marks as Highlands sheet being referred 

 to as " Ceylon Highlands sheet." " Ceylon," in this connec- 

 tion, is of course merely a trade term for rubber made up in 

 plantation form, and its use is duo to the fact that this type 

 of rubl)or was first brought to the notice of European and 

 American dealers by the efforts of the Ceylon planters, who 

 exhibited their produce at International Exhibitions whenever 

 an opportunity arose. 



Coara rubber was exhibited at the Colonial and Indian 

 Exhibition of 1886 by Raj awe 11a and Kandanuwera estates.
