According to British Consular Report No. 1996, Annual series, the Ryan Tin Com- 

 pany did a good deal of work in 1896, and in the first six months produced upward 

 of 260 tons of black tin. Machinery has been erected. Great drawback to working 

 tin and coal deposits of territory is lack of transportation facilities.

" Another interesting problem for research for the student of mineral chemistry is 

 furnished at the tin ore deposits at Embabaan in Swaziland. Together with tin ore 

 occur at this locality extraordinarily rare and most interesting minerals, such as 

 aeschynite, euxenite, fergusonite and monazite." 



1049. HAMPTON, J. H. On the occurrence of tin. 



Trans. Geol. Soc. South Africa, Vol. 4, 1899, Johannesburg, pp. 37-40. 



The tin deposits of Malay Peninsula, Mt. Bischoff and Swaziland, near Embickel- 

 weni are treated in a brief manner. The author visited Swaziland in 1889-1890, and 

 at that time received the impression from appearance of the country that tin existed 

 in lode or alluvial form.
