28 The Timbers of British Guiana. 



Physical Characters. Weight (so far recorded), 49-52 Ibs. per 

 cubic ft. Hardness, Grade 3, very hard; compare Blackthorn. 

 Smell or taste 0. 



Colour of Heartwood. Reddish; red-orange; darkens but little 

 on exposure to the air. Surface clean. Sharply denned from the 

 Sapwood. Colour of Sapwood like oatmeal; width lf-2J ins. 



Bark. About f$ in. thick, nearly smooth like Beech; brown 

 within, fibrous, gradually becoming granular or crumbling towards 

 the outside, where it is covered by a whitish epidermis. A thin 

 layer of short bast. Surface of log beneath bark, striated or smooth. 

 Bell states that the Bark has an odour of Balsam Capivi. This is 

 not apparent in the specimen. Perhaps it soon passes off. 



Uses, Qualities, etc. " Used for furniture. Is readily procur- 

 able in logs up to 30 ft. in length, squaring 12-14 inches " (12). 

 Hard to saw; fissile, takes nails badly; planes badly and turns and 

 polishes indifferently. A handsome furniture wood that may be 

 worth attention for export providing that it be not subject to the 

 attacks of worms. My specimen is badly worm-eaten.
