RUBBER IN MEXICO AND ELSEWHERE. 



T^HE more recent references to rubber cultivation in 

 Thk India Ruhber World have been devoted prin- 

 cipally to the work in progress in the Far East, for the 

 reason that such work is more advanced there than in any 

 other region, and more definite results have been attained. 

 But with all the advance there, and all the success actual 

 and prospective, the product of the Eastern plantations 

 cannot for years to come form a large percentage of the 

 world's total production of rubber, or lower materially the 

 price level of crude rubber. These result.s, however, are 

 already of a character to prove beyond doubt the possi- 

 bility of producing good rubber under cultivation, under 

 conditions which render its production more profitable 

 than any other form of agriculture to-day, while it is as- 

 serted by Ceylon planters of long experience that the 

 growing of rubber would be distinctly profitable even at 

 half the prices now obtained. To our minds the e.xperi- 

 ence of the Far Eastern planters thus far should prove 

 most encouraging to those who have engaged in rubber 

 culture elsewhere under proper conditions. 



To come nearer home, without doubt the question of 

 rubber planting, in the minds of the American public, has 

 become involved with some doubt, due first to the element 

 of impatience for commercial results from the investments 

 made in Mexico, though the initial attempts there to plant 

 rubber systematically were not made until years after the 

 pioneer work in Ceylon. The beginnings in Mexico, by 

 the way, were quite independent of any work in progress 

 in any other country. They related to a different species 

 from those planted in the Far East, and labor and other 

 conditions were so different that the experience gained in 

 the latter region was not such as to render direct assistance 

 to planters in Mexico. The Mexican enterprises in rubber 

 planting, therefore, have been developed very much as if 

 no rubber had been planted elsewhere. 



Mistakes were inevitable, and some of the plantations 

 were bound to result in failure. Moreover, many people 

 doubtless have an incorrect impression of the length of 

 time which has elapsed since the first development of in- 

 terest in Mexican rubber planting, owing to the amount 

 of talking that has been done. Persons may be heard to 

 speak of plantations as being seven or eight years old 

 which really have not half that time to their credit. An- 

 other fact is that a few concerns have been organized on a 

 palpably dishonest basis, and certain others have been 

 managed unfortunately, to the discredit of the whole rub- 

 ber planting interest. Meanwhile there have been fraud- 

 ulent gold mining companies organized at the public ex- 

 pense and there have been failures of banks presumably 

 organized on a sound basis. We do not find, however, that 

 good gold mining propositions are less difficult to finance 

 than formerly, or that the public has any less confidence 

 in banks. 



We have called attention hitherto to reports which have 

 gained currency through the United States consular ser- 

 vice in Mexico, characterizing most unfavorably all rub- 

 ber enterprises in tnat country. We have felt it to be
