" Muamba-Camba " in Angola. Reaching large dimensions up to 

 3 ft. square. W 39—49. R 34,951 lbs. Yellowish or brownish, 

 with dark zones, becoming with age a rich dark brown, handsome, 

 moderately hard and strong, straight, coarse and open in grain, 

 and very durable, proof agairst termites and other xylophagous 

 insects. This wood has probably a great future on the European 

 market, being one of the finest known substitutes for Teak, which 

 it resembles in colour, and, when sawn tangentially, in texture. 

 Though inferior to Burmese Teak, it is superior to Javanese, being 

 worth 6s. per cubic foot. It is at present used in West Africa 

 for railway-sleepers and building purposes. The grain picks out 

 so that it will not polish.
