fore, a valuable article of trade. Besides the silver mines, rich mines also 
of copper, and some of gold, lead, iron, and tin, are found. 'The most 
distinguished mines of the State, of older and more recent date, are the 
following: 
he mines of Santa Eulalia, near Chihuahia, have during the last 
centu ury uced immense masses of mates as sheet pretties fact may 
Eulalia mines, by a grant of one real (12$ cents) on every marc of silver: 
(worth $8 25) obtained from the mines. This fund was created in 1717, 
and in 1789 the cathedral was finished, at an expense of $500, - "The: 
amount of silver taken in these 72 years from the mines would, therefore, 
be $52,800,000. The abundance of lead found in Santa Eulalia makes 
the smelting of the silver ore very convenient... The mites are at present 
not yet exhausted; but from intrusion of water, want of capital, and the 
attraction of new mines, they are but little worked. 
The mines of Parral (Hidalgo) are the oldest of the State, and have also 
been extremely productive in silver; but for want of regular mining, most 
of them, though not exhausted, are made inaccessible and worthless 
The mines of Santa Barbara, discovered in 1547, were renowned for’ 
both silver and gold ores, but are now entirely abandon

~The mine of Sierra Riea, west of the old Presidio de (San Carlos, was 
begun to be-worked by a company in 1829. ‘The prospects at first were 
most flattering: the superficial layers of the silver ore produced from one to 
hundred mares in the carga, sometimes 150, and in one instance even 
327 mares; but at the depth of 80 varas the mine seemed to give = 
the invasions of hostile Indigns became at the same time so trouble 
some, that the mine was abandoned. 
Such extreme richness of the ore is of course nots common: occurrence; 
and the result, mind by comparison of Mexican and European mines, that 
the mines in Mexico are generally poorer as to the relative amount of silver, 
but far superior aan to abundance and extent of the ofe, seems also to Cor 
respond with the mines in the State of eeetnes because a aivee mine 
furnishing from three to four ounces of silver in the carga, is generally 
considered good enough to be worked with advantages and many with less ~ 
per cent. are rendered profitable. 
In recent times, the mines of Guazapares and of Jesus Maria acid 
attracted most of the capital of the State. The latter, southwest from Chi- — 
huahua, on the height of the Sierra marens were discovered in 1821; and 
so many valuable silver mines, and some gold mines, too, have since a 
time been opened, that it promises to be for a long: time one of the ric
