thirteen new gold dredgers are re-
ported TO have been ordered for use
on the Yuba River in the interest of
the Harmon syndicate. The two larg-
est gold dredgers that have been built
are operating on the bottom lands of
the Yuba near Marysville: The dredge
miners have the idea that at least $780,
100000 in gold Will be rescued from the
river bed. A large electric plant VIII
be constructed In the mountains to fur
nish power for. the dredgers on the
Yuba near Marysville and also for
those near Oroville.
The money that the dredger miners
are supposed to be making is favorite
theme with the papers printed near the
scenes. of operation. The Orovtlle Reg
lister publishes some estimates of the
cost Of dredging for gold in the vicinity
Of Oroville. II the figures are entirely
correct the showing is remarkable in
many respects. especially when the re-
wards for success are considered
Among the statements that the Regis
ter makes are the following:

other form Of gold working. The gold found is
spread almost evenly through the graVels, and
In this district each OF the dredgers be
the entire year. so that the output of a dreige
can be stated at nfty~tWo times $1,000, or fl4'l-
600 a year.
As iheFe are now twenty-five dredgers run
ming here, taking both sides OF the river, the
output for the next twelve months may be
safely estimated at not less than TWO ana
A single year, taking IN about half Of i9O2
and half Of 1908 showed shipments from here
OF Sl.32S, COO
At chat time there were not as many
dredgers running. as there are now, and OF
course IL IS not presumed that all OF. the go'o
shipped by the express company,
During the month Of June. 1904. a report
from one Of the dredgers operating south OF
OroviIle showed that the :rotal number OF CUBIC
yards for each day was 1874 The dreqge
averaged twenty hours and eight minutes per
day OF working time The power was on
iwentE-four hQurs during the month
The cost ef labor for the month was SS2a,
while the cost for power was ST2a The cost
FOR water was $50 The total amount paid out
making a total expense ST $500 The average
Cost of working yard OF earth was OS2 cents
The following data relative to costs -ol a
dredge operating at OToVEle are the averages
covering three years OF work and are taken
from the hooks Of the company;
Size OF buckets. cubic feet; average speed

p. Probably the best showing that. can be made
as 10 low costs is IN another instance at Orc
Vile where a monthly statement shows that
500 go cubic yards were dredged, or an aTer-

OF the ground per cubic yard was lS9 cents
