IS apt to wonder if after all there is anything

The last few weeks, as the "great mechanical
engineer of the Pacific coast,'' might also
have something to do with the formation of
the idea, perhaps after all thisi is but s:sound
and fury, signifying nothing" A visit, how
ever, to the interior of the mine completely |
such ideas and gives the impression
the expenditure of 100000 on a forty |
stamp mill will be speedily repaid by the out
come from the mine. Completeness in all
the arrangements above and below the sur-
face is noticeable at once. As the descent is
made in the safety cage no cross-cut is en-
ceuntered at the 1OO-foot level, but just
above the 200-foet level the north vein ia
pierced by the shaft and cross-cut on the
north at a distance Of ten feet. All opera
lions on the north of the shaft are in this
vein, which is again cross-cut at the 3OO-foot
level at a distance of 40 feet from the shaft,
and on the 40O-fost level at a distance of
twent, six feet from the shaft, which meas
urements give an idea of the dip Of the vein.
On the south side of the shaft two large veins
are encountered and cut at the two, three,
four and five hundred-foot levels. Between
tho fonr op1 fva Enndrod foot louole
smaller branch vein Or spur has been struck,
dipping north at an angle not very different
from the inclination of the north vein. At
the two hundred-foot level the centre vein is
cross-cut at q distance Of 129 feet, and at the
three hundred-foot level at . distance of 142
feet. At the four hundred-foot level the
same vein is cut at a distance Of 1915 feet
south frsm the shaft, showing that it dips
south at a very decided angie between the
three and four hundred-foot levels.
The main or south vein is. the larg-
est of all, and promises the richest
results from its development in the near fu-
turs. On tho 2OO-foot level it las not been
cut at all. On the 3O0-foot level the cross
cut south cuts the main vein at q distance of
312 feet from the shaft, and has already been
advanced into 1t "a feet. The observer will
draw the inference from the apparent direc-
ton Of this main vein At this point, and from
its groupings under the mill, on the surface.
that it dips greatly to the north below the
3OO-foot level. Finding the centre vein Dip
ping quite as greatly to the south between
the same levels, the natural conclusion is
that these two veins come together at some
point near the 40O-foot level, on which a tie
mendous body of water was recently struck.
and which is now bulk-headed at a distance
of 80 feet from the shaft, awaiting the opera
tons OF the new Cornish pump. The only
explanation Of this head of water on the 400
foot level, so soon after striking on the one
above, is to be found in the dip to the north
of the main vein between these levels, the
body Of water following this vein downward,
The new pump will very soon be in position,
with a capacity to manage the water, and will
thus afford an opportunity ofjudging whether
Or net this hypothesis is correct. In the
meantime its accuracy is almost demon.
strated by the distance south at which the
centre vein was cut on the 400 foot level,
B esides these main veins there are two othe,
smaller streaks or veins of ore, which have
already been pierced, one dipping north from
. cropping at the southwest corner of the
mill, and another dipping north from a poin,
under the hosting works, from both of which
very rich ore has been taken. Allusion has
already been made to the spur running off t.

near the SoO-foot level. Stopping is being
done now principally at the sections indicat
ed on the two and three hundred foot levels
some twenty-five tons of ore being extracted
daily. The shaft is now full of water up to
point a short distance below the 4OO-foo
level, and the bulkhead on the cross-cut froa
the 40O-toot level stops operations on tina
level until the Cornish pump can be oper
ated, as before stated. From these details
faint idea may be gathered of the exte mt o
operations in the Moulton mine, but the rich
ness and size of the ore bodies can only b,
realized by an actual visit to the drifts. A
far as all indications Eay be trusted the or,
will be abundantly forthcoming for the new
mill, and the latter when started, as it will
be shortly, will be beyond a doubt the mos
complete dry-crushing, chlsridizing mill OF
the Pacific coast.
