Mammoth Ducyrus IDredse to Be
ErActed on Red River Meadows.

VIM. IL. DuttcTS y DiOs., d
Iookane, have purchased the Rec
liver meadows, near Elk City, and
Ire now putting in q mammoth ele-
Iator or chain bucket dredge to
andle the gravel. The machine
being built by the Bucyrus Co.
I South Milwaukee. Wisconsin,
md the first shipment of machin.
nv, consisting Of 10000 pounds,
Fill arrive at Lewiston in a few
lays.
Messrs Chas. E. and Walter E..
Buffers, the promoters Of this
treat enterprise. have been on the
round all winter putting in a saw
bill and getting out the necessary
umber and logs for the dredge.
! nd as soon as the machinery ar.
Ives the dredge will be construct
d at once and they hope to get the
htire plant installed and in opera
ion early in the spring.
Mr.. Edmund Juessen, the well
(nown manager of the American
bill hydralic elevator mine at Elk
tity, is getting up an improved
|old saving device for Messrs But
Frs and has spent some time at
|outh Milwaukee, experimenting
be construction of the same. The
liant will be lighted by electricity
Ind is guaranteed to handle 1000
|ards Of gravel every "a hours.
fhe ground is situated at the low
\ end Of the lower Red River
headows, at the mouth of Sigel

|old An effort was made a few
|ears ago by Messrs. Driver & Gal
lin to work this ground by a dredge
|at their appliances were ON too
|nall q scale aud not we'll adapted
pr the purpose. The gravel pros
|ected well but when they came
b clean up, 10 and behold, the cur
ent of water had swept the gold
|nd quicksilver all away and the
Enterprise was abandoned. With
Pc modern appliances and Mr..
|eessen's new gold-saving devices,
is safe to say that these mead
Tvs will prove a highly profitable
Enterprise to the new owners.
