Arlington Copper company's work pc,
cause it means TO them much IN iocai
business way, but the experiment Is aiso
being closely watched by expert miners
metallurgists. and financiers generaiy,
because of the adaptation to this ola anu
neglected mine. with low bearing ore OF
the latest and most scientihc processes
for the extraction of copper
The company has already investeu si9o'-
900 in machinery and buildings. ana u Is
said that the plant is now as hneiy eauip-
nod as the famous Anaconda mines IN
Montana.
The company is exceedingly confident OF
success. despite some discouraging opln-
ions of old time miners who think cop
mar cannot be obtained in sufficient guam
t,t,es to make it profitable. The ore Is
very variable in quality, but the company
has enough good average ore in signt 70

investment.

ore may run as low as two per CENT

heretofore been employed will shortly be
Increased to several hundred men, with
La. night and day shift.
The company is considering now
whether to connect the works with the
greenwood Lake branch of the Erie Rail
road or the main lire Of the Lackawanns
railroad at Rutherford. The latter spul
would be slightly longer, but 1t woule
connect the company with a coal-carry'
ing road, which the concern regards as 9
considerable advantage
This method Of communicating with tht
great markets is In marked contrast *
the methods of the early part of the sew
enteenth century, when the Schuylers
Il who first worked the mines, were obliged
to ship all the ore in shallops down th'
Passaic River and thence to Bristol Eng
