 impregnated with a resin, but it is a useful timber. 



DetariuTTi senegalense. Yields excellent timber. 



Khaya senegalensis, the Senegal mahogany. Does not 

 reach a great size ; timber of first-class quality.

 beautiful timber.

 dimension. 



Pterocarpus erinaceus, the Senegal rosewood tree. 



Tamarindus indica. Yields an ornamental wood. 



The palm, Borassus flabelliformis , the wood of which, 

 exclusive of the pith, is extremely durable.
