clastic, acting on the proteins in the rubber, and rendering 

 them immediately available for the fungi. The fact that the 

 majority of fungi fall in the two genera mentioned above 

 supports the view that these fungi are probably rich in 

 enzymes. 



The spottings can be prevented by adding I part of formalin 

 to 800 parts of latex, the formalin inhibiting the development 

 of the spores, so that the rubber is dry before the fungus has 

 enough time to produce visible spots. Sodium bisulphite is 

 also useful as a preventive, probably due to its influence ::i 

 inhibiting enzyme action. 



Latex diluted with water results in rubber with a greater 

 tendency to spotting. The results obtained in this connection 

 are concordant with the experience of many planters troubled 

 with spotting. 



External inoculation after preparation can only take place 

 under extraordinary conditions of retardation of the drying 

 period. Under ordinary conditions of drying there is no 

 danger to be anticipated from spores falling on the surface of 

 the rubber after preparation.

INCREASING THE YIELD OF FUNTUMIA BY THE SPARANO 

 TAPPING METHOD IN THE BELGIAN CONGO.

[ABSTRACT.] 



The plantations of Funtumia elastica, the Ireh or Lagos 

 rubber tree, have given, as a rule, unsatisfactory results, the 

 yield beinsi much smaller than that obtained from Hevea.
