The produce of the Mexican mines is veiy 

 unequally apportioned. The 2,500,000 marks, or 

 1,541,015 troy pounds of silver annually exported 

 to Europe and Asia from Vera Cruz and Acapulco, 

 are drawn from a very small number. Guanaxuato, 

 Zacatecas, and Catorce supply more than the half; 

 and the vein of Guanaxuato alone yields more than

 Those of Zacatecas were next commenced, and that 

 of San Barnabe was begun in 1548. The principal 

 one in Guanaxuato was discovered in 1558. As the 

 total produce of all in Mexico, until the beginning of 

 the eighteenth century, never exceeded 369,844 troy 

 pounds of gold and silver yearly, it must be con- 

 cluded that during the sixteenth little energy was 

 employed in drawing forth their stores.
