U. S. Geol. Surv. Bull. 285, 1906, Washington, D. C, pp. 146-140, fig. 1. 



Description of the El Paso tin deposits, first described by Weed in U. S. Genl. Siirv. 

 Bull. 178, 1901. Gives a general description of the topography and geology of the 

 Franklin Mountains, and a partial analysis of the tin bearing granite. The tin 

 deposits are close to faults. Found little new development. States that water can 

 be obtained in the mesa east of the mountains.

Describes briefly the geological structure and formation of the Franklin Mountains. 

 Thinks the veins are similar to those of Cornwall, and that the ores are formed 

 largely by replacement. Notes the absence of topaz and presence of wolframite.

California Journ. Tech., Vol. 2, No. 3, 1903, Berkeley, p. 53. 



Quotes from the " British South African Export Gazette," of September 4, 1903, 

 that three tin-bearing lodes have been discovered in the Transvaal. 



1174. . Gold and tin in northern Rhodesia.

Taken from South African Mines, reports a deposit of streimi tin on west bank of 

 Lualaba. 



1175. . Tin discoveries in the Bushveld. 



Journ. Soc. Arts, Vol. 52, 1904, London, pp. 736-737. 



A summary of particulars respecting the discovery of tin in the Bushveld, near 

 Pretoria, taken from the " African Review." 



1176. . Tin in the Transvaal. 



Mg. Sci. Press, Vol. 89, 1904, San Francisco, p. 295, 250 words. (Probably from 

 Hall, A. L., No. 1181.) 



Digest: Mg. Mag., Vol. 10, New York, p. 442. 



" Notes on the occurrence of this metal in several different places in the Transvaal." 



1177. . Tin in the Transvaal. 



Mg. World, Vol. 24, 1906, Chicago, p. 771. 



States that the first output of tin in the Transvaal has recently been declared. Tin 

 lodes in various forms have been traced over a considerable area. Other tin areas in 

 the neighborhood are being discovered from time to time. 



1178. . Failure of tin mine at Vlaklaagte, South Africa. 



Eng. Mg. Journ., Vol. 82, 1906, New York, p. 180. 



It was expected that this mine would prove one of the world's gre.itest deposits. 

 Unless things improve considerably, the tin mine at Vlaklaagte cannot run much 

 longer. Up to date the total amount of material won is ro\iglily 2rA/^ long tons 

 cassiterite equal to 17.85 tons or 1.75 per cent metallic tin, from 1020 tons treated.
