foreigners.
From the best information could obtain, I am
led to believe that at least $4,000, 900 of the
$40,OOO,0 900 were taken from the rivers, and
that their richness has not been sensiblv dimin-
ished except in few locations, which had early
attracted large bodies of miners This amount
has principally been taken from the northern RI
vers, or those which empty into the Sacramento;
the southern rivers, or those which flow into the
San joaquin, having been comparatively, but lit
| tie resorted to until near the close of the last
season. These rivers are, however, believed by
those who have visited them, to be richer in the
precious metal than those in the northern part of
the gold region. :. ~
There is one river which, from reported re-
cent discoveries, and not included in the descrip-
ton of those flowing into the great plain west O.
the Sierra Nevada, is rich in gold as any of
them. That is the Trinity, which rises north of
the head waters of the Sacramento, and dischar-
ges into the Pacific, not far from the fortieth de-
gree of north latitude.
| There are as nearly as my recollection serves
me, twelve principal rivers in which gold has
been found; but most of the twenty millions in
the above estimate, was taken from six or seven
of them, where it was first discovered and most
accessible.
Adopting the hypothesis that the gold found
In the beds of these streams has been cut or
worn from the veins in the quartz throu oh which
they have forced their way, and considering the
facts that they are all rich, and are said to be
nearly equally productive, we may form some
idea OF the vast amount of treasure remaining un
disturbed in the veins which run through the
masses Of rock in various directions, over space
of forty or fifty miles wide, and near five hun
dred miles long @T'sa
