In fact, many metals of universal estimation, such as gold, silver, mercury, copper, and iron, in a pure state, in grains, in masses, or in dust, as well as mixed with other metals, superficially or in veins, are found in the extensive territory of Sonora; lead, or combinations of lead, for aiding in extracting metals by fire, and for the construction of munitions of war, amianthus or incombustible crystal, divers ores of copperas, exquisite marble, alabaster, and jasper of various colors, as well as quarries of stone of _chrispa_ and magnetic stones, muriate and carbonate of soda, saltpetre or nitrate of potassa, are, in enumeration, the mineral productions which are found in abundance in the territory of the state of Sonora, which comprehends the region from the river of Fort _Monte Clarasal_ at the south to the Gila at the north, and from the Sierra Madre at the east to the Colorado at the northwest. To the disgrace of the nation, these authentic and exact notices of the marvelous riches of this remote state have availed nothing in determining speculators (_empresarios_) to resort to those places in pursuit of a fortune so certain, or at least to have avoided, by the means of colonization, the loss which is _feared_ of this inestimable jewel. The territory of the state of Sonora lacks nothing but security [from incursions of Indians] in order that the hand of man may be profusely recompensed for his labor. Virgin soils, where the agricultural fruits of all climates not only flourish, but many of these improve in quality; navigable rivers, which contribute in part to the easy transportation of the products to the ports of the Pacific for exportation and consumption; mines and _placers_ of precious metals, in many of which there is no necessity of capital to explore and collect them--are not these stimulants enough to attract there a population thrifty and civilized? In order to ascertain the mineral riches which the nation may lose in a short time, we call attention to the mineral statistics which follow, although they are imperfect and diminutive. As already we have said, the whole of Sonora is mineral; but as among us we only give this name to those places in which there have been discovered and worked a conjunction of veins, it results that the places in this state to which for this cause has been given the name of mineral are thirty-four. Some of the mines are _amparadas_ [viz., worked sufficient to confer a legal title to the occupant], and are imperfectly in a state of operation. The names of all of these two classes, which are sixteen in all, are Hermosillo, San Javier, Subiate, Vayoreca, Alamas, Babicanara, Batuco, La Alameda, Rio Chico, El Aguaja, Aigame, El Luaque, Saguaripa, La Trinidad, San Antonio, and El Zoni.
