A CORRESPONDENT this month challenges certain 

 -^~*- statements regarding a large yield reported from a 

 few cultivated "Para rubber" trees in Ceylon, contributed 

 to our January issue, as being incredible. The Editor 

 of this Journal is unable to offer any personal testimony 

 in the case, but the statement referred to was accepted 

 and paid for and published in utter good faith — all the 

 more because the same facts, in one form or another, 

 have become common property in the Far East, where 

 the means exist for readily exposing any canard quite as 

 much as iu any other region known to us. In the daily 

 and other journals of Ceylon and the Malay States the 

 facts iu regard to rubber culture are regularly and more 

 thoroughly discussed than is true of any other form of 

 material development to which newspapers anywhere 

 else on earth devote attention. 



But the question is not whether a few trees on a cer- 

 tain plantation actually did yield an unprecedentedly 

 large amount of rul)ber, though that yield has not, we 

 believe, been disputed by any competent authority. 

 What is more to the point is the suggestion made in a 

 Ceylon paper that an exceptionally large yield may be 

 produced by a few trees, under specially favorable cir- 

 cumstances, as a result of extra care, without establish- 

 ing a new standard of average yield for all rubber trees, 

 everywhere. What was sought to be illustrated by our 

 Ceylon contributor was that under certain new methods 

 of treatment a larger yield of rubber was attained than 

 from the same or similar trees under the best practice 

 before known. And this we considered proper matter 

 for publication, with a view to encouraging rubber plant- 

 ers generally to devote their energies to continued ex- 

 perimenting in an effort to get better and better results 

 from their labor, through the continual employment of 

 new means. 



We print the communication of Mr. Waldron, with 

 his computation of what the ultimate yield of Ceylon 

 rubber would be, on the basis of the large yield we re- 

 ported in January, with the comment that nobodj', even 

 in Ceylon, has expressed the idea that such a yield can 

 be obtained in general practice. But even if it could be, 

 in a given country, with a given species, it does not fol- 

 low that like results would be necessarilj' possible every- 

 where, and with every species. Our own idea is that 

 the rubber planter should figure out the minimum yield 

 which would afford a profitable return from his capital, 

 and whatever he can realize above this is so much more 

 than tlie gains of the average man. There is no reason 

 why miraculous returns from rubber should be expected, 

 more than from any other field of investment. 



Mr. Waldron has begun to ship rubber from his plan- 

 tation in Nicaragua, and we feel that he has reason to 

 be congratulated upon his initial results. And a few 

 planters in Mexico are beginning to realize the fruition 

 of their work, without rea.son, as we view it, to be dis-
