THE INDIA RUBBER WORLD 



[ March i. 1910. 



of the Hevea tree alon< : or, to speak more guardedly, it has not 

 been shown in (..cur in am other rubber tree to the extent that 

 advantage may In taken of it in practice. The demonstration of 

 wound response quickly influenced the method of lapping Hevea 

 trees followed in the East, and a considerable part of this paper 

 bears upon tapping systems. 



Referring to the tendency to a decline of sources of wild 

 rubber in Africa. Mr. Parkin regards the Amazon region as the 

 only source of real importance for such rubber in the future. 

 The supply on the Amazon is well nigh inexhaustible, and al- 

 though our author has brought his studies of this region so well 

 up to date as to be able to treat of the recent rubber congress at 

 Manaos, he does not seem to be hopeful of a very large ex- 

 pansion in the Amazon output of rubber. 



Mr. Parkin, in The India Rubber World, January, I, 1910 

 (page 105), emphasized the importance of applying the principle 

 of seed selection to rubber trees such as is carried out for all 

 other cultivated plants. This suggestion was not heeded at the 

 time, but of late its importance is being recognized in many direc- 

 tions. In support of his suggestion now repeated Mr. Parkin 

 writes: "Apparently there is a strain of Hevea now growing in 

 the East which is a poor latex yielder but a great seed bearer. 

 If care be not taken, estates may be planted with this variety, 

 only to cause grave disappointment in a few years' time, when 

 the trees reach the bearing age." A concluding part of this paper 

 will deal chiefly with the preparation of rubber from the latex.

 (creepers), in addition to the Funtumia trees.

ACCOUNTING EVERY BUSINESS MAN SHOULD KNOW. BY 

 Elisha Ely Garrison. New York: Doubleday, Page & Co. 1909. [Cloth, 

 umo. Pp. 188. Price, $1.20 net.] 



I'm- book on accounting embodies a thorough treatment of 

 the subject, in a masterly way, indicating that the author has a 

 very broad knowledge of accounting, from both a theoretical and 

 a practical standpoint. Being couched in general terms, the 

 work is more comprehensive to an accountant. It is not suf- 

 ficiently elaborate for the guide of one knowing little or nothing 

 of accounts.
