The object Of this survey has been de.
Rnsd and limited BY the terms Of the sub.
seription agreement upon which ths fund,
for carrying out the wsrk are expected I.
be raised.
1t has been deemed Advisable to issus
this bulletiR in advance lof these which
will appear frcm time to time during the
progress Of the survsy, in order to inform
the public Of its scope and advantages.
The prsaent survey does net conte m plate
any precise trianguIstion Of the region to
be surveyed, nor any detailed Topographic
cal work; this will no doubt be accom-
pished in due time by the general govern.
Snent. For the present, the maps and
surveys Of the land office will be utilized
as basis upon which the topography an d
geological features will be drawn in the
Beld, the position Of details being eeunss-
ted with the township and section
corners, mineral monuments, etc, BY
means of magnetic compass bearings and
other convenient and rapid means Of
measurement. The surf1ce oontours will
be sketched in from barometie Observa-
tions. The strike and dip of strata will
likewise be sketched in upon the Reld,
from measurements made by the olinom etor
and magnetic compass. By these rapid
methods reconnaissance can be carried
over the entire county, including outlying
mineral districts lake Valley, Kingston,
Aillsboro and the Mcgolon districts), in
a comparatively short period, traversing
every enc Of the 26O or more townships
several times if nocsssary.
The detail work Of the survey will how
ever, bo in part carried on at the sanae
time in reglons Of particular Importance,
such as iniAeral districts already known.
as well as the now districts which the sur-
vsy IS expected to develop In such re-
gionS the detail work will consist in map
ping the direction and dip of mineral
bearing veins, deposits, dy aes, faults, etc.
upon large scale and in making examln.
tons Of mineral deposits, with especial re-
ference to their nature, value, continuity,
the relatiYe age Of different systems Of
veins OF deposits in the same district. |
their relation to those of other districts,
the effect of fauItIng, and all other phe-
nomena beating upon the economy of min
ing, Gro reduction etc
When lhp general reconnaissance is
cenpleted, the geologic and topographie

IN contours and eolors. on a scale of Q to 4 /
miles to the inch. from which the plates
or the published reports will be reduced
The structural geology viii be exhibited
by numerous sectional drawings showings
he superpositon Of the various strata,
.he fAultlngs, folds, etc. These maps and
drawings, together with special maps OF
mines and collections Of ores, minerals,
ossils, etc, will be placed in the museum
IF the survey at Silver City, where they
will be open to public inspection.
Following upon the work above referred
O, will be the arrangement in systematic
'rder of all the facts observed in the prog
ess Of the survey, so that their relation
nay bo traced out. Especial attention
yll DO paid to tracing out the limits Of
he various metal bearing horizons, some of
Which are at present known only by few
rarely psrceptible outcrops. Studies will
'e made OF the linss of dynamic force
which contributed to the existing arrange
nent of strata, eruptive masses, and fault
ystems Of the region, as well as Of the
aetamorphic indications which accom-
amy the mineral deposits, with a view Of
seertaining far as possible their signif-
,anee in the light Of established geolo-
le science. Purely theoretic deductions, {
owever, will be left for readers of the {
lrvey to mako. The scope Of the survey
,ill therefore be limited chiefly to the col
sctiou of facts bearing directly upon :
ractioal mining.
1t is well established fact, although s
ne not as generally known and appreCia-
ID amongst miners and mine owners here
