Tin is found on the Benoue, an affluent of the Niger. In the French Congo it 

 is found in the Crystal Mountains, on the Oubanghi and Ouelle Makua, also at 

 Massinga (or Massinda) north of the village of Agapata in the upper basin of 

 the Banghi in a region of Archaean rocks and granite with copper. 



In the northeast part of Swaziland near the frontier of the Transvaal, tin has been 

 known for a long time. Deposits at Embabaan only are promising. Though tin 

 veins are present, only the alluvials have been worked. 



There has been the following production: 



Year 1894 1895 1896 1897 1898 



Tons 143 250 240 70 53 



According to Dr. Molengraaff the region is one of mica, talc, chlorite, and 

 amphibolite schists with some quartzites carrying magnetite, similar to the forma-, 

 tion at Hospital Hill, Johannesburg. The cassiterite is found, not in the quartz, 

 but in the pegmatite cutting the schists.

 appearing up to the middle of 1908 has been omitted from this bibliography.
