23,000,000 cubic yards. From Folsom down
a distance of five miles there were bank Lines
which were mined out in former times. A
mile below Folsom there is sand bar 1,5o0
feet long and 200 feet wide. The width of
the river at that point, including the sand
bar, is 600 feet. For three miles above
ALDER CREEK
The south bank was thirty to fifty feet high.
On the opposite side the bank is high hill.
Near the mouth of Alder creek l noticed
water-worn rocks four feet above the surface,
indicating that the filing had not yet reached
ancient high-water marks. Slickens is pipe
or any clay mixed with water. 1t looks
like hydraulic cement when wet. The
next mile below Alder creek the south bank
is 80 or GO feet high. Below Sailors Bar, for
three miles, are gravel banks. -Four miles lie
below Sailors Bar first noticed sand drifts
on the upland. At Buffalo creek the banks
are quite high and composed of sand. AT
Farmers Diggings there has been considers
Bile mining done, and large quantity of cob
BILE covers the old workings. Below Farmers
Diggings we come to what we call Sacra-
mento valley. The current at sthis point, at
low-water stage, varies from one half to one
mile FER hour. Below this point islands and
bars of sand appear in the channel, covered
with slickens. From Routier's down we be-
gin to find willows. In Rooney's field,
on the south bank, there is large md
sand bar is at least one foot deep.
Where I crossed the north levee, near
Brighton, l found it had hight of ten feet.
l have all the notes that were taken at the
time these observations and surveys were
made. 1 made no direct estimate of the
amount of filing between Folsom and Sacra-
mento. I measured the water in the Ameri-
can river October 80, 1881, where it passes
under the bridge at Folsom. The area of
the water section was ,065 feet. and the dis.
charge was about 700 cubic feet per second.
A constant stream of 700 cubic feet Of water,
charged with one per cent. of sediment,
would in the course of 365 days discharge
SIG 600 cubic yards of material. This 700
cubic feet of water is the amount running In
the American at its lowest stages. High
water would be many hundred times greater.
The width of the river at Folsom would
average stream $50 feet wide and 20 feet
deep. The velocity of the stream at that
hight would be 3 feet per second. The dis
charge would be $1,000 cubic feet per second.
The fall from the
IOWA HILL MINES
To the river is about 1900 feet. They are
gravel mines. I visited those mines at the
same time l went to Gold Run. The ma
terlal or Inc Iowa bll mines Is slmi-
lar to that of the Gold Run. The top
soil of these mines is similar to this Robin
son No. II. The general character of the
bank is something like this (Robinson No. 2).
l measured the mines at Iowa Hill, and
found that 2,50U,000 cubic yards had been
deposited into the North Fork and G, 100000
cubic yards into Indian creek. This creek
empties into the North Fork about 12I miles
below the mouth OF Canyon creek. All of
the mines of Iowa Hill dump either directly
or indirectly into the North Fork. Where
the Iowa Hill mines tail iuto the North Fork
direct is from two to three miles below the
mouth of Canyon creek. At that point the
current of the river is from two to three miles
en- hour. One man is all that is used in the
handling of giant. Most of the bars in the
river are composed of light material, and
easily set in motion by current of water.
II the current remains strong and for any
considerable time the entire bar will be car
ried down stream. When the water falls or
becomes low the same causes that produce
the bar swept away will form a similar de-
pcsit. There are large deposits in Indian
creek at the mouth of the mines, but no de-
posit at the mouth of the creek. Since the
mines were closed the river above Folsom has
become quite clear.
The direct examination of Mr.. Alardt was
closed at 1890, and the Court then adjourned
until $3.50 A. NJ. to-day.
