The total aggregate cost of one crop of C'astor-oil and two 

 crops of groundnuts would therefore be $185. 



The gross revenue of one acre of Eicinus has heen already 

 given as $175. 



From tlie fiiJ-ures obligingly su]iplied us by the Manasrer of the 

 Singapore Oil Mills the present pric-es of groundnut for which 

 there is an excellent market, stand as follows : 



Grade 1 unslielled $700 per koyan of 40 piculs. 



2 ,. 650 



3 ,. 600 

 Shelled nuts $25 per ])icu]. 



Oil cake 8.50 to 9 per picul. 



The aggregate of the two crops of groundnut i.e. 2,900 lbs. 

 (= 2,170 catties) of shelled nuts at 25 cents ])er catty would bring a 

 gross revenue of . . . . . . . . . . . . $542.50

Castor-oil revenue $175) ^ . . 717.50 



Less expt'iiditure . . . . . . 185.00 



Leaving a nett profit per acre of $532.50 



If, howe\er, making allowance for the vagaries of seasons, for 

 undue prevalence of pests, and also for the fact that the groundnut, 

 in this ease is aji interplanted crop,- — not a pure crop — we out down 

 the returns from that source by one fourth and bring the amount of 

 the two crops to 1,6527,50 catties of shelled nuts, the revenue from 

 groundnuts would fall to (1627.50 X 25 ) .. .. $406.85 



which added to the Castor-oil cro]) . . . . . . 175.00

I'SKS OK CaSTO]!-OIL. 



The many uses to which castor-oil is {uit make it one of the 

 most important raw materials of industry.
