Wherever the patches of oxidized ore
are found in the roof, they are sofr,,

Eight shafts have been sunk, the two
principal ones known as No. 8 and No 8
being supplied with hoisting works j."

The shaft has three Compartments, Que
for a pump and, two for double deck
cages. There are two horizontal hoist
ing engines which may be run together
or independently. with a combined 500
horse power. Nearly all Of the castings
of extraordinary weight. for l4inch
Cornish pump are. on the ground; the
missing parts are said to be on the road,
where they were dropped at the time OF
the suspension ofthe work. The pump! !
ing engine was not delivered, but huge
foundation pit has been excayated for IL.
| As stated in that part of this report
which refers to the Raymond 4 Ely, the
pump in that mine will probably be
found Of ample capacity to deal with the
water from the Meadow Valley and the
ground which would be drained byyit, so
that it will probably be many years be.

Meadow Valley pump. 'r' -. ,,.
