 those mines from the Capital. 



"The Carmen vein, north of Durango, in the State 

 of Chihuahua, among the mines of Batopilas, upon the 

 western declivity of the Sierra Madre, has produced 

 enormous yields of silver. From this vein three masses 

 of pure malleable silver were taken, weighing collec- 

 tively 870 pounds. 



"The mines of Santa Eulalia, in Chihuahua, are 

 the most northern of any mines in the Mexican States 

 which have been worked with any regularity, and 

 proved by the richness of their ores the superiority of 

 the northern mines of Mexico over those of the interior 

 and southern part. The registered yield of the mines 

 of Santa Eulalia from 1705 to 1737 was $55,959,750, 

 or an average of $1,748,742 per annum; from 1737 to 

 1791 the yield exceeded $44,000,000, making a total 

 for eighty -six years of $100,000,000. 



"This extreme northern district was abandoned in 

 the year 1800 from its proximity to hostile Indian 

 tribes, whose savage incursions could not be prevented 

 by the mining population, who received no assistance 

 from the Mexican Government, which was engaged 

 in civil discord; and the flourishing haciendas for re- 

 ducing metals, which were once in such a flourishing 

 condition, are now a mass of ruins. Thus the tan- 

 talizing wealth of the northern mines of Mexico and 

 the rich tracts of Arizona and Colorado have remained 

 undeveloped until the present day. 



"The report of Mr. Glennie, a very enterprising 

 and intelligent English traveller, who made, in the 

 years 1824 and 1825, a number of excursions over 

 the northern Sierra Madre range, confirms the good
