_ , for building purposes; window frames, 



shutters, doors, furniture, verandahs, fences and shingles are 

 made from it in West Africa (Kew Bull. 1891, p. 43) ; used for 

 sleepers, planks, doors, tables, benches and furniture in Nigeria 

 (Thompson, I.e.), the only kind used in house building, durable 

 and resists the attacks of ants better than any other; much 

 valued on the Coast (Barter, No. 3330 (1859) Herb. Kew) ; 

 durable and ant-proof and fairly easily worked; so regularly 

 sound in large sizes that all the "^larger dug-out boats are' made 

 of it, Port. E. Africa (Sim, For. Fl. & For. Res. Port. E. Afr. 

 p. 118); used for house-building, gates, doors, tables, &c.. 



Wood 



Angola (Hiern, Cat. W 



used for railway 



construction, joinery, etc., Ivory Coast (Courtet, L'Agric. prat, 

 pays chauds, x. 1910, p. 462) ; weight about 50 lb. per cubic ft. 

 <Sim, I.e.), density 0-721 (Courtet, I.e.), will not float in the 

 green state (Foster, Nig. Trees & PL p. 63) and a specimen in 

 the Kew Museum (Dawe, No. 689, Uganda) has specific gravity 

 0-673 = 42 lb. per cubic ft. Of this specimen it has been 

 reported "weight per cubic ft. 46 lb., a rather coarse-grained 

 wood of uniform yellowish colour with pretty zigzag markings on 

 a tangential section. It can scarcely be said to be ornamental 

 «.nd is of little, if any, value for export; the heartwood is 

 irregular in shape and the sapwood from l|-2i in. thick; it is 

 doubtless a useful wood for building purposes ; it will not take 

 nails, being fissile, is hard to saw, planes fairlv easily, but the 

 grain rips out; turns easily, but finishes badly (Mus. Kew: 

 Report by Herbert Stone for Imp. Institute). 



This tree is reported amongst others to be tapped for the 



No 



mix with 



66, 1910, p. 47). Deposits of " Carbonate of lime " are often 

 found in the trunks of trees that have become hollow or fissured 

 by some agency, probably lightning or other powerful cause.
