$50 feet. The ore vein ranges from 80 to %
feet in width Another shaft about 80 feet dis
tant and 20 feet deep, connects with the breast.
This bed is not at present as extensively worked
as the others.
The New bed is abOuthalf mile west ofthe
the former beds and is owned by the Lake Cham
Main Iron Ore CO. The length Of the shaft is
nine hundred feet, the extent ofexcavation
about 100 X 125 feet. The pure ore OF this
he'd commands a price Of 500 per ton, and
the separated $500, and it - impossible
for the company to fill its orders at these prices
The pure and separated ore is used with the
old bed - screened or shot ore, in mixture Oh
one half each. for making slabs for boiler plate
bv f,rgcs in Essex and Clinton counties These
slabs are sold throughout Pennsylvania As the
standard for this purpose.
Two engines are required to raise the ore from
the first six beds, one Of go horse power located
in a building situated Immediately north of

of wood a day are consumed by these engines.
