at present to its requirements. There are several mines and 
mills lying idle in this district, some from mismanagement, 
some for want of ores. The San Marcial American Mining 
Company has sent, in the last two months of the same year, 
17,000 dollars from their ten-stamp mill. The Governor’s 
mine at Banawachi has sent this year, up to November, 15,000 
dollars from its twenty-stamp mill. In the Babicamora 
district, below Arispe, a Mexican is erecting a mill, which 
promises to be remunerative, as much silver was formerly 
obtained here by the old patio process. At La Dura (Rio 
Chico) a Mexican company is commencing work. Then La 
Barronca (San Antonio de la Huerta district) produced con- 
siderable silver for two years, but this has been temporarily 
arrested while a tunnel is being made. At Chipionena an 
American company is also commencing work. At Zubiate a 
Mexican company sent 30,000 dollars to the mint in 1867, | 
and expected to double that amount in 1868. The mill works 
fifteen stamps. Besides Banawachi, Governor Pesquera has a 
mine at Cananea (three days’ journey north of Arispe), of lead, 
silver, and copper. This was a good mine, but having been 
abandoned during the revolution, the Apaches burnt the steam 
engine and destroyed the smelting works. Santa Theresa 
and Los Ginga of Zuape are both good mines, and worked to 
advantage. The yield of the above veins, taking an average 
of all the ores, is about the following :—
