red colour it imparts to the leather and it is only satisfactory when 

 used in combination with the better class substances. 



Roots of the Mangrove mixed with " divi-divi " {Oaesalpinia 

 coriaria) have been used at a local tannery in Jamaica (Kew Bull. 

 1892, p. 229). 



The bark of the West Indian and S. American Mangrove is used 

 locally as a wound remedy and febrifuge, and it has been recom- 

 mended as a specific for leprosy (Merck's Ann. Rep. 1905, p. 175). 



The wood is hard and durable ; the specific gravity of a specimen 

 in the Kew Museum (collected by Mann in 1861) is 0*969 = 60*5 lbs. 

 per cubic foot. According to Chevalier, the density is T093 (Les Veg. 

 Util. L'Afriq. Trop. Frang. fasc. v. p. 224). Used for building 

 houses in the Western Province (Dawodu, Herb. Kew) and in 

 parts of S. Nigeria near swamps for piles, and fuel. It has been 

 recommended for paving blocks and railway sleepers. Logs have 

 been sent to the Hamburg market, but beyond the interest they 

 created as possible piles and beams for mine-shafts, no demand 

 for them appears to have arisen (Baillaud, Journ. D'Agric. Tropicale. 

 1901, p. 201).
