THE INDIA RUBBER WORLD.

the wood of the "liority" palm arc fastened to the tree with 

 pegs, the joint between tree and trough being filled with 

 clay. He claims that the milk is coagulated by the addition 

 of alum dissolved in hot water. The freshly coagulated latex is 

 then pressed between boards to expel as much water as possible. 



His description is not altogether clear in many respects, and it 

 may be that he has confused the coagulation of the Here a latex 

 with the boiling of the "mangabeira" milk. It is, however, true 

 that much of the Matto Grosso rubber is poorly handled, and is 

 usually air cured instead of being smoked. That, however, will 

 rectify itself when the territory is opened, as the smoked product 

 brings a much better price. Matto Grosso "coarse" is to-day quite 

 common ; "fine" and "medium" are also on the market. 



.\r\ immense region lying along the eastern range of the Andes 

 Miountains and extending to the Amazon belongs to Peru. It is 

 known as the forest country, or montana. and is watered by a 

 great network of rivers. These forests are not only rich in 

 cinchona, vanilla, and cacao, but there is a great deal of india- 

 rubber. There are three distinct kinds of rubber gathered in the 

 .Amazon provinces of Peru: (i) "caucho." which is the product 

 of the CaslUloa Ulei; (2) "seringa," borracha or "jebe fino," 

 which comes from a Hevea; and (3) the "orco-jeringa" or 

 "weak fine" Het-ea. There are a number of theories regarding 

 the reason for the shortness of fiber in the weak fine. The com- 

 mon belief is that, as it is found on high lands far above the 

 sea level, it is due to locations where the Hcvea is not at its 

 best. It is possible, however, that it may be caused by the ad- 

 iriviiirv nf nnotht-r latex with that of the HcTeii.
