SILVER, 



Mexico's greatest mineral wealth, undoubtedly, lies in its vast deposits of silver, 

 as compared with which its treasure of gold is almost insignificant. In our general 

 remarks upon mining, we have described the ancient and modern silver mines, and 

 have related the history of their discovery. It only remains, now, to indicate the 

 districts in which silver is the principal product. For further particulars, the reader 

 is referred to the detailed description of the resources of the states. 



Native Silver, says Humboldt, which is much less abundant in America than 

 is generally supposed, has been found in considerable masses, sometimes weigh- 

 ing more than two hundred kilograms, in the mines of Batopilas. From time 

 to time, he adds, small branches, or cylindrical filaments, of native silver, are 

 discovered in the celebrated vein of Guanajuato ; but these masses have never 

 been so considerable as those which were formerly drawn from the mines of 

 Encino, near Pachuca, and Tasco, where native silver is sometimes contained in 

 foliated gypsum. It is now found in certain districts of Batopilas, State of Chi- 

 huahua, Guanajuato, Pachuca and Zacatecas ; and argentiferous and platiniferous 

 deposits in the district of Jacala, State of Hidalgo, known as Santa Maria de Alamos.
