Use. — The plant is used in Europe and India for a pot-herb, but it is most 

 valuable for tlie oil it ])roduces. 



The oil resists putrefaction lon<2^er tlian any other fixed oil, and is considered 

 the most delicate (»f all tlie sweet oils, except olive oil. It is used in India for 

 food and for anointing the body, and for the fragrant oils used in religious 

 ceremonies. It is used in all civilized countries for the same purposes for 

 which olive oil is used. It is applied to illuminating purposes, to the manufac- 

 ture of cosmetics antl hair dressings, and especially to the manufacture <jf fine 

 toilet soaps. 



It congeals at a much lower temperature than other oils, and is hence well 

 adapted to cold climates. It has of late years been largely employed in the 

 manufacture of spurious butter, or oleomargarine. The natives of India make 

 an article of diet of the seeds, and also of the refuse cakes after the oil is 

 pressed out of the seeds, and they ])lace the seeds in the graves with their 

 dead relatives.
