Review of the Crude Rubber Markets ' 305 



A N American civil engineer who has decided to become 

 ^^ a manufacturer of India-rubber goods complains 

 that there is no complete guide to the business published, 

 and that the rubber trade is singular in this respect. He 

 cites other branches of industry, such as iron, glass, pot- 

 tery, and so on, that have a literature which, if closely and 

 intelligently studied, should give one an intimate knowl- 

 edge of those particular industries. In this our friend is 

 right to a degree. Provided he be a man of faculty, a 

 natural mechanic, and an acute observer withal, he might 

 do something in the lines cited by the application of book 

 knowledge. It is possible, indeed, that at the end of a 

 series of years he might grow into a great ironmaster, a 

 wealthy potter, or a king in glass manufacture, but the same 

 intelligence and application would place him at the head 

 of some great rubber factory. In any or all of these cases 

 his book knowledge would be supplemented by his con- 

 stantly varying experience, and that in a short time would 

 constitute his most valuable asset. It is perhaps easier to 

 become an e.xpert potter than to be an all round " rubber 

 man." And the reason is that the rubber business as a 

 whole is an aggregation of results that have come from 

 thousands of complex experiments. The basis of the 

 business is as simple as possible, but the application of the 

 simple theory involves such a variety of changes in practice 

 that it is a common saying among the expert that there are 

 " more things that are not so " in rubber manufacture than 

 in any other of the world's industries. And that is where 

 books of necessity fail the practical man. 



THE NEW "PARA RUBBER" FROM THE EAST. 



A T a recent auction sale in London six cases of fine 

 ^^^ rubber from Ceylon, the product of cultivated trees 

 from Para seed, brought ^s. 4|(/., or about 81,4 cents, where- 

 as the highest price for real Para rubber reported during 

 the week was only 2,s. o^J. per pound. This is not the 

 first instance of exceptionally high prices obtained in the 

 London market for " Para rubber " from plantations in 

 the East. The declining profits of coffee growing have 

 forced the planters in that part of the world to seek some 

 more remunerative planting, and already thousands of 

 acres are covered with rubber trees undei cultivation. Not 

 unnaturally attention has been turned chiefly to Para rub- 

 ber, on account of the universally higher price which it 

 commands, and now that the first trees planted are becom- 

 ing productive, the result of the sale of every little lot ex- 

 ported seems to the planters to confirm their choice. 

 There is no computing how much planting of Para rubber 

 since 1900 has been due to the sale of 327 pounds, sent 

 from Perak to London in that year, at 3,?. lod. 



It is not impossible that these planters may yet be disap- 

 pointed, for the reason that it remains to be seen whether 

 what they are producing is really "Pari rubber." The 

 tendency in nature is for all species to be influenced by a 

 change of habitat. It appears, for example, that trees of 

 the genus Hevea — the source of Para rubber — when grown
