This mine, known to the aborigines from time immemorial as a ‘‘ cave of red earth,” from which they ohtained paint for thei bodies, was first discovered to contain quick silver ahout four years since, during ex periments made by some Mexicans to smelt the orefor the purpose of obtaining gold, which they supposed it to contain. Ahout two years ago it fell into the hands of Barron, Forhes & Co., who sent on hands, tools and funds to commence working it, Untortunately the vessel fell intu the hands” of the United States forccs, and was confiseated; the operations of the mime were of course delayed till the arrival of Mr. Forbes himself a few months since, with miners, tools, and whatever things he was ‘ahle to procure in Mexico, to enahle him to make a fair experiment ou the capahilities of the mine. The great trouble was to obtai suitable apparatus for extracting the ore, At length jour potash ketiles were found, which were set iu a furnace of adobes, with condensers of mason-work immediately adjacent—a wretched apparatus indeed for managing so subtle a thing as mercurial vapor. The mode of working was to fill each of these pots in the morning with 400 pounds of the ores of average quality, hroken in lumps of the size of apples, put on the covers and due them with clay. The fires were then kept up till near night, when the furnaces were allowed to cool gradnall The next morning the condensers wer opened, and the metal dipped up; which usually amounted to from 200 to 300 pounds for the four pots. This was a much less percentage than the assay iudicated, and it was ohvious that a large portion of metal was lost. The upper parts of the pots and condensers were found to he generally coated with a crustof sulphuret of mercury. Mr. Forhes wished to devise some way of extracting the metal without mixing lime with the ore in the roasting, hut was nn-— successful, At lengtha kiln of lime, which occurs in theimmediate vicinity, was hurned, © and mingled with this, the ores yieldinga © vastly larger percentage of metal. In the last three weeks ahout 10,000 pounds of metal have been extracted with the same apparatus, heing a yield of over 50 per cent. Whether the ores were picked or not the writer cannot say, but presume they were, Between 15,000 and 20,000 pounds have been extracted in about two months, only six miners having been employed in digging the ore, and the hands of the establishment, all told, miners, furnace-men, wood choppers, ete., etc., numbering onlya score, The mine is probably yiclding a net profit of $100,000 a year with its present cruds apparatus. Withsuitable furnaces and iron cylinders or retorts, the mine would easily yield $1,000,000 and upwards. Mr. Forbes sails to Europe shortly for the apparatus necsssary. The bed has as yet been followed but a few hundred feet, but the ores grow more and more rich and abundant. The other mines opened in the vicinity have not yet heen sufficiently developed to decide upon their character. Ore has hesn found in fifteen or twenty other places within a few miles around, and within a few days in hills that do not seem to belong to the same range with that which contains the mine already descrihed. Some ores of silver have also been recently discovered in this region ; but I hays had no opportunity of procuring any gennine specimens as yet, and whether silver mines worth the working will be fonnd 18 at least problematical.There are traces of coalin the country, but nothing of value has yet heen discovered. Gold has heen found recently on the Sacramento, near Sutter’s Fort. It occurs in small masses iu the sands of a new millyace, and is said to promise well.
