one day will be ours, is one of the largest ports for the export
of flour on the Pacific coast north of Chili. She also exports
several millions in silver annually, which finds its way direct
to the English market. Under an intelligent system, the Sonora
mines would yield a hundred millions a year, and the supply is
inexhaustible. If any reader doubts this statement, refer him to
the statistics of Humboldt, Ward, and Wilson, most unquestionedand valuable authorities. Both Humboldt and Ward note the fact
that the silver deposites grow richer as they are traced farther
North. There can be no doubt that the most extensive and valuable
mines, both of pure silver and silver mixed with copper and lead,
are within the limits of Arizona.

The yield of the silver mines of Mexico, as computed by Ward and
Humboldt from the actual official returns to the Government, from
the conquest to 1803, amounts to the enormous sum of
$2,027,955,000, or more than two BILLIONS Of dollars. Again, Ward
says: "I am aware that many of the statements in this and the
preceding books respecting the mineral riches of the North of New
Spain, (Sonora, including the 'Gadsden Purchase,' Chihuahua, and
Durango,) will be thought exaggerated. THEY ARE NOT SO; they will
be confirmed by every future report, and in after years, the
public, FAMILIARIZED WITH facts which are only questioned because
they are new, will wonder at its present incredulity, and regret
the loss of advantages which may not always be within its
reach."

Of the present mining operations in the Territory of Arizona, the
most considerable, in point of labor performed and results, is
"The Arizona Copper Mining Co." This company is incorporated by
the California Legislature, with a capital of one million of
