d
to the single company of dragoons at Los Angeles, and the one
company of artillery at Monterey. Nearly all business had ceased,
except that connected with gold; and, during that fall, Colonel
Mason, Captain Warner, and I, made another trip up to Sutter's
Fort, going also to the newly-discovered mines on the Stanislaus,
called "Sonora," named from the miners of Sonora, Mexico, who had
first discovered them. We found there pretty much the same state
of facts as before existed at Mormon Island and Coloma, and we
daily received intelligence of the opening of still other mines
north and south.

But I have passed over a very interesting fact. As soon as we had
returned from our first visit to the gold-mines, it became
important to send home positive knowledge of this valuable
discovery. The means of communication with the United States were
very precarious, and I suggested to Colonel Mason that a special
courier ought to be sent; that Second-Lieutenant Loeser had been
promoted to first-lieutenant, and was entitled to go home. He was
accordingly detailed to carry the news. I prepared with great care
the letter to the adjutant-general of August 17, 1848, which
Colonel Mason modified in a few Particulars; and, as it was
important to send not only the specimens which had been presented
to us along our route of travel, I advised the colonel to allow
Captain Folsom to purchase and send to Washington a large sample of
the commercial gold in general use, and to pay for the same out of
the money in his hands known as the "civil fund," arising from
duties collected at the several ports in California. He consented
to this, and Captain Folsom bought an oyster-can full at ten
dollars the ounce, which was the rate of value at which it was then
received at the custom house. Folsom was instructed further to
contract with some vessel to carry the messenger to South America,
where he could take the English steamers as far east as Jamaica,
with a conditional charter giving increased payment if the vessel
could catch the October steamer. Folsom chartered the bark La
Lambayecana, owned and navigated by Henry D. Cooke, who has since
been the Governor of the District of Columbia. In due time this
vessel reached Monterey, and Lieutenant Loeser, with his report and
specimens of gold, embarked and sailed. He reached the South
American Continent at Payta, Peru, in time; took the English
steamer of October to Panama, and thence went on t
