Silver, boiled in an infusion of Goraka fruit, becomes 

 perfectly bright and clear, and for this reason silver- 

 smiths often make use of it. 



The resinous gum obtained from this plant might be 

 made use of as a pigment, but in its crude state appears' 

 to attract insufficient attention. 



[Low-country up to 1,500 feet.]

A small tree, with smooth brown bark, easily distinguished 

 from the last by its small fruits. 



Generally distributed, but not so common as the last. 



The wood is hard and close. It is used only for temporary 

 purposes, as posts, &c. Gamboge is obtained from this 

 species in some quantity, though the tree is not made special 

 use of for its extraction. Weight, 56 lb. per cubic foot. 



[Deltota, Hantane, Uva.] 



24. — Garcinia echinocarpa. 



Madol, S. 



Trim. Cey. Flor., vol. I., p. 96. 



A large tree, with dark bark and many aerial roots near 

 the base of the stem. 



It can easily be recognized by its fruit, which is covered 

 with sharp prickles (tubercles). 



Moderately common at high elevations and down to about 

 2,000 feet ; frequently gregarious. Occurs plentifully in 

 the Peak range, and among the Panilla hills in the Atakalan 

 Korale, Sabaragamuwa. 



Wood rather light, easily split. It is useful as a shingle 

 wood, and if tarred becomes fairly durable. Weight, 50 lb. 



The seeds yield an oil that in many remote villages is 

 used largely as a luminant by the poorer classes. 



[Hunasgiria, Madulkele, Rangala, where it is the principal 

 tree of the hill forests.]
