mine, but in order to open the ground East by
the aid Of a cross cut drift, it will be istis-
pensable at present to sink the Eastern Shaft a
few feet, when the sinking of this Shaft should
be suspended. The cross course may be driven
from the Lump Shaft with but little expense.
the ground being principally pipe clay, by
which that part of the mine will be drained
With attention TO the several levels, DC, double
the number of hands might be employed either
with tribute or tutwork, without any expense
to the Company when the men NAV obtain
high wages, and the dividends be augmented
The price per foot for sinking the Engine or
/ Lump Shaft is s 10, which is more than usual in
consequence of the Green Rock which requires
blasting more than any other except the Glass
Rock. The ground for operating is, however
/ by no means extensive.
! The greatest expense is in operating the Lump
Shafts am inclined to think the Western
Lump Shaft should of itself drain the mine ad-
vantageously to answer every purpose.
| zinc ORE 1t frequently happens that the
Lead Ore in assures gradually diminishes and
is eventually entirely replaced by Zine Ore
Such is frequently the case in this mine Large
quantities OF the Carbonate are disseminated
throughout the mine, in fact hundreds of tons
are laying on the surface, rejected as worthless
dross.
OF the valuable properties of this Ore, mi
ners as well many scientific and well in
formed persons, have not the least Knowledge
An analysis proves II to be true Carbonate of
Zinc, giving about forty per cent, and often
more, of pure metal

generally, and in this valuable field of specula-
ton ii is to be found in abundance 1t there
fore demaEi's attention. The demand for the
article is increasing from the increased demand
for brass. l would remark, that the great guam
tiy raised in England is insufficient for the de-
mand, and that large quantity from other parts
of the globe is annually imported into that
Kingdom.
In this as in other mines obstacles have hith- |
erto opposed its progress. such as the unsettled
character of the country, high wages for the Ia
Dor, dc Still they do not threaten to continue
great here, ii except the advance which max
arise from the discovery of other Lodes in this
section which undoubtedly embraces more.
The mineral vein already proved in this sec
ton is sufficient to engage a great increase of
laborers, with advantage TO the Company and /

seen westward, near the streams, and is very
powerful. 1t must, however be remembered
that the same phenomena may possibly be
caused by comparatively small veins of other
minerals. othing can be correctly known,
however until operations are carried on in depth
at which time all viii be explained
With regard TO the Surface Operations such
as Buildings, dc, everything has been done with
economy and skill The Flat Rods. with their
connections are wei laid in, without the least
friction with any part of the machinery. The /
length of the Flat Rods from the Lump Shafts
to the wheel, which is twenty five feet in cir
cumference and six feet breastwork are 1850 /
and 400 feet, respectively. The wheel has
sufficient power to drain the mine 230 feet from
the surface, the clay Strata being calculated /
to retain the water Ia fact, there is little no
expense required for outlays in the future oper- |
ations of this mine, the Lump Shaft excepted. |
Ia conclusion, would remark the Deficiencies /
and imperfections which l well a
critical examination may detect in the Report, /
without being aware OF the length of time per-
mitted me to complete it. Thus. an explana-
tion examination hastily made hss been OF
necessity as hastily reported, preventing obtain
ing accuracy of chemical analysis suitable /
materials for Geological Report. Without be- |
ing hastily or oyer-sanguine in expressing my |
opinion in regard to the value and importance /
of this NINE have endeavored TO avoid errofs. |
1t is with the greatest satisfaction and pleasure
am able to pronounce the Linden Lead Mines" /
to be emphatlcally the richest of all tEat L have
examined, and must congratulate the adventur-
on their operations and undertakings. believ-
ing the mine to be lasting and of dividend
paying character.
