| Dear Sir On Satur-
day last, llth inst. examined the Lode
in tSe new drifts in the Linden mines,
below the Glass rock, and am much pleas
ed with its character and ppearance
which confirms me in the high opinion
have always entertained of the Linden
mines. The lode is composed of Black
Jack, (Btende) alcareous Sp ,r, Trf) and
lead ore or Mineral The upper portion
Is considerably mixed with the Glass rock
1t has more of the character of contn-
uous permanent lode than anything else
| have Sc. n in this lie "a region and my
chances of observation have been e,,nsid-
erable The Sheet will average from two
TO two and half feet thick and jud q

no opportunity of weighin. anv portion of
the lode to get at on which to ound
calculation, but tnIik | am sale in assu,n.

IN waich case each foot will contain Hobs
pure mineral. They are workin. on the
lode cross cutting from both the western
an eastern shafts, and have advanced 80
feet in the former and about It in the
latter 1h,se shafts are some 220 faith

of the lodes pitches /, uncertain; very prob

much further OF the width | cannot
, sp1ak dec,dedly for want of data, but the
Messrs Heathcock had a sheet in an open
ing above the Glass rock which was 200
feet wide an this will certainly be as
wide and probably wider. Assuming 200
feet as the width hy 220 fathoms or 1920
feet Iength YOU have an area of 264 600
feet Tnis ro Present appearances will
average 2&3,t thick which will MAXI 594,
900 cutie feet which at 40fbs Mineral per
cubic foot will amount to III $50 tons be-
tween the two poin where the lode is
now in sights OF the value of this you
can make your own estimate.
The course you are taking of cutting
across the range is the right one you will
OF cours sink shafts on NE north side as
soon us you have reached it, and | would
suggest sinking another shaft on the south
side somewhere about midway between
tue arc~en shafts Cross cut there also,
and sink sh it on the north side oppo-
site | would advise driving those cross
cuts, sinking shafts &c, before taking out
any mineral except What Is removed IN
cross cutting sinking &c., and before en-
pioying many hands on 1t bring IN level
adit deep as you can which Will drain
al the upper workings at leaat to the
glass rock; or, a though YOU are now
keeping out the water comfortably the
necessity of keeping it five feet lower at

bove, ycu will be liable to be flooded. and
1t would not do TO have a large number of
hands with any chance of being hindered.
