aiming tne geolOglca relations OF the rocks
found among the mountains This charac-
terlstc was prevalent as far as the crossing
Of the Scott River mountains, and westerly
for distance Of not less than 40 miles. In
this place we shall resume the consideration
Of the quartz veins, and their relations TO the
other rocks, which will more fully illustrate
the character Of this portion of the State.
The examination OF these rocks was conti-
nued from Lewis Bridge on the Trinity, in
northeastery direction: to the base of what
is known as Browns Mountain, a ridge which
forms the eastern border of the Weavervlle
basin. On this ridge there are no vestiges
of any other than the primitive series, and
trapean rocks, COMFORTING in character with
those spoken of on the Trinity ridge. On the
western decvty, and little more than half
way down to the level of the basin, the veins
were found to be situated in talcose states,
which extend in . broad band from this point
to the bottom of the hill; as usual, the vegc-
table within the line of its range become
much more sparsely distributed than upon
either of its tanks, where the trap rocks and
GRANTEES were found to predominate, Fol
lowing this line for several miles, these tai
cose rocks were found to be part Of an exten-
sive range which composes the major portion

of the town of Weaver, which are designated
as the Weaver Mountains. and which may
be known by their peculiarly barren aspect
when approaching this town from any point
of the compass. This belt extends nearly
across the basin, and has been struck, at va
rious points, in sinking shafts and driving
tunnels for placer mining.
Taking westerly direction along the base
of the ridge, and following that line for four
or FIVE miles, observed three dikes of quartz
cutting the granite, and one near small
branch which empties into Weaver Creek,
which entered the greensboro below the gran
ite In company with some three or four of
the citizens Of Weaver, visit was made to
the high ridge west Of the west branch Of the
main creek In the distance Of two miles in
reaching the summit of this hill we crossed
as many as five distinct parallel odes, three
of which ! subsequently iout,d to contain
gold. On the following day, an examination
of the southern end of this ridge was made,
aud heavy dixie of this rock was found oc-
cupying the summit, and cropping out at va
ri0us points on the decvity towards the RI
YER | think that this dixie is Identical with
one which is found on the south east flank Of
Browns Ridge, and it unquestonably cuts
entirely through that mountain.
ln AL the veins which passed under my OBJ
servauon during my ramblcs in this section
of the State, not one was found to enter any
of the rocks of sedimentary origin, but were
confined exclusively to the primitive group
| On the Trinity River, and between that aud
| the Scott, the same features were prevalent
| in this particular, with one exception, which
| WIS found at The distance of about two miles
from Palmer's ferry; here the Areipite states
on the LETT Of the trail were cut through by a
single small ven which was traeeabe fer q
distance of nearly one mile, and like several
veins in the more southern counties OF the
State: this lode had a strike neatly due east
and west, nearly at right angles TO what are
known here as the primitive lodes, This is
an interesting fact in this county, and serves
70 show a regularity in those perturbatons to
which this part Of the continent has been sub
iccted at different periods. nder the arti-
Gle Of Mines, | shall have occasion to allude
to this subject, in connection with the com
varatlye value OF the mc,aieIous character
Of these lodes, 50 far as they have been exam
med, and are at present understood in this
State.
From the illusions made 70 the primitive
veins in my report Of last year, some idea OF
their intrinsic value may be CLEANED with re-
ference TO the prospects which they present
for mining operations.
Finding so great preponderance of lodes
OF this character in this district Of country,
took occasion to collect and examine a con-
siderable number of these rocks from differ
ent veins, and situated miles apart These
collections were from the counties of Shasta
Trinity and the eastern part Of Klamath, the
aggregate number Of which was forty three
and Of this number fourteen were from the
Weaver Basin and its surrounding ridges, Of
which nine specimens, or about three-tiiths
r contained gold Of the remaining twenty
nine specimens twenty-five were found to
contain the same metal. AS but one Of this
entire number Of veins was fOnnd TO be oca-
ted for mining purposes, within my knowl-
edge, hope that may not incur the charge
Of giving favorable report on private prop
erty for pccunlary considerations, for to be
frank in this matter, found a less quantity
in the vein which was claimed than in any
specimen which proved to be auriterous.
The above facts respecting the aurifcrous
character of the quartz veins Of the northern
section Of this State are detailed for the pur-
pose of calling attention 70 that important
source Of wealth, which in other parts Of the
State has proved Of 50 high value, and
which thus far in the extreme northern por-
ton Of the County have been engaged in to
so limited an extent One Of the greatest
causes, however, which have acted in pre-
venting capital investment in this branch Of
mining, is the hitherto almost inaccessible
condition of this section from bad roads, pre-
,, renting the transit Of heavy machinery which
is 90 necessary TO success in the reduction Of
ores. This difficulty at present seems likely
to be overcome, for active measures are now
being taken for the construction Of good ave-
nues Of communication, which will insure
the means Of the transportation Of heavy
freights to almost any portion Of the north
ern interior.
