The rubber juice is contained chiefly in the lactiferous ducts of 

 the bark, but to some extent also in the wood of the stem — in 

 fact, the entire plant contains a certain amount of rubber. While 

 the process of extraction is secret, yet in. the main, it appears that 

 it is analogous to the production of sugar from the sugar-cane. 



The fibrous by-products of the rubber vine are considered as 

 possessing an importance possibly greater even than that of the 

 rubber itself. The bark of the vine yields 6% of the weight of 

 the whole stem, and is a pure cellulose fibre, having a silky lustre 

 comparable to Japanese ramie fibre and almost equal to cotton. 

 It is thought that it can be used as a substitute for Egyptian cot- 

 ton, especially in the manufacture of fine underwear and other 

 articles. The pods of the vine besides containing a fair per- 

 centage of juice, have large quantities of silky cotton such as 

 would be suitable for stuffing pillows ; when refined and specially 

 treated, It can be successfully spun with ordinary cotton. The 

 woody substance of the vine, when bleached and worked out, 

 yields a fibre suitable as paper pulp. The vine can be best har- 

 vested after the fruiting period. — Agricultural A^eivs.
