Conclusions and recommendations. 



from 



" The investigation has shown that this sample of the rubber of Cryptotfegia 

 grandijlora from Bombay is of very fair quality, and there is little doubt that 

 tbe carefully prepared product would sell readily in the market at remunerative 

 prices. The elimination of the vegetable and mineral impurities would consi- 

 derably improve the quality of the rubber. 



" In view of the statement that large supplies of this rubber are available 

 it is suggested that a trial consignment of one or two hundredweights should be 

 prepared and forwarded to the Imperial Institute for sale in London so that 

 its commercial value can be definitely ascertained." 



8. Castilloa elastica. After another year's experience and 

 observation this plant has proved to he absolutely unsuitable for 

 the Deccan and, in company with Hevea braziliensis, it is simply 

 grown under shelter as a natural curiosity. 



9. The plants of Funtumia elastica referred to in last year's 

 report under the synonym of Kickxia africana are in perfect 

 health. Their growth is now remarkably slow and this is said to 

 be a characteristic of the plant. Conflicting reports are published 

 on the value of the rubber produced by this plant, but the general 

 concensus of opinion in India seems to be that the plant is not 

 worth growing, 



10. Fious elastica. We have one young specimen, and the 

 following interesting information was received from the Reporter 

 on Economic Products to the Government of India, on a sample 

 of rubber produced by the parent of this plant in the Empress 

 Gardens, which is approximately 20 years old. It is gratifying 

 to hear that this Assam rubber plant, which would thrive 

 admirably in the Konkan near rivers, produces a rubber more 

 valuable than that collected in its native country.
