that person could at this time travel IN
foot only with great difficulty. The road has
all slid out and into the river. Some of the
slides extend to the top of the mountain.
Some OF them are two and three miles
10 length, and from 30 to 100 feet wide. The
California Water and Mining Company's
canals head at Loon Ike. From Loon lake
is is dropped into Guerle creek, thence taken
through tunnel iato Pilot creek, and thence
down the ridge TO Georgetown The main
reservoir is LEON lske. Its present capacity
is about 600 000, COO cubic yards. It's ultimate
cs9scity, when the dam is comL leted, will be
1850, 900 900 cubic feet. The present capacity
of. cir canal, is about l 200 inches. They
have not cost less than 100000. The Ell
Dorado Deep Gravel and lining Company
has great many canals and distributing
bitches. The main canal takes it's water
from the South Fork Of the American river
at Cedar Rock, about 80 mics from
Placerville. Toe length OF the main trunk
is twenty four and half miles. The fumes
are eight feet wide and six ieet deep,
The maia supply reservoir is Silver lake. It
has an area Of about 600 acres. II contains
WHEN drawn upon 500 coo, coo cubic feet OF
water. Echo lake contains ill a similar man
ner go, QUO, coo cubic feet Of water. There
are several smaller reservoirs, but they are
only for distributing purposes. The property
OF the FL Dorado Deep Gravel sud Mining
Company has cost over 81. 000 000. / have
done all the engineering for that company for
several Years. The bitches and canals cost
more than 100000. Their capacity is 600
inches. The Pcrk cau9ls carry from ], 900 to
1,5OO iaches of water. They were constructed
at very early date-I think IL 1851 and
1852. am we'll acquainted with the country
between Weber creek and the South Fork,
and the north side of the South Fork. | have
been surveying mines in that region for sew
eral years: There ale at LEASE fifty miles
OF this old river channel, filed with grave!
deposits, within the caunty Of Ell, Dorado
L ave surveyed claims on these cham sls,
| both under ground and ON tho surface. Most
| OF these mines are WORKED by what is called
the DRIFT process. Next TO the bedrock in
| these channels is a compact strata of gravel.
This gravel Is alwals covered with lava. The
gravel channels of El Dorado county are diff
| terent from those Of Gold Run. The mines in
Ei Dorado county being covered TO so great
| depth by lava, necessitates their being worked
| by the drifting process. The most extensive
| hydraulic mining ever done in That county
was IN the Excelsior mine. A great many
other mines have bsen worked similarly The
pit washed at the Excelsior mine covers an
area of forty acres, and has an average depth
of 100 feet. Ten acres have been washed of at
| Spanish Hill to a depth Of $50 feet.
The tailings from those mines are dumped
| into streams tributary to Weber creek,
| About 10 per cent. of the mining done il Eel
| Dorado county has been done by the hydraulic
process. Rock creek, John Town creek and
Irish creek have all tiled up to great depth
with sand, cobbles and gravel Drift mining
is being carried on very extensively at the
present time. / know of eighty stamps run
ming on drift gravel They crush from three
and half to four tons per stamp day.
| Quartz stamps crush from ton to a ton and
! a half per day. There is mining going on,
more or less, over the entire county. Since
| / have observed the South Fork, I have
noticed no perceptible change in its channel
| The fill in the river at Coloma is from to 20
| feet deep. IL is composed of cobble and sand
and is very compact Weber creek is about
thirty miles in length The depth Of the fill
ing in this creek varies in different plsces.
At Morrili's bridge it is at least fifteen feet
! deep. In other places there is hardly any.
| The banks of Weber creek are very irregular.
In some places they are nearly vertical. A
| great many Of the residents along Hang
town creek have lmpounded tailiugs for egri-
cultural purposes. 1t makes excellent and
productive soil. l visited the Gold Run mine
on the 18th of November, 1881. l examined
the material Of the pit, the tunnel, the dump,
and then followed down the North Fork from
the mouth of Canyon creek to Rice's bridge.
| Witness described the material composing the
bottom of the mine find by measurement
that Che sewerage discharge from this city, at
this time. to be 455, 600 gallons every "a hours.
| found four artesian wells at the head of
Burns slough. two of them 60 feet, one 70
| feet. and one 200 feet IN depth. l examined
them twice. They discharge about 435 gal
Ions per minute. The new canal carries off
approximately. at the present time, about
$1,000 cubic feet of water per day. On the
14th of December 1 found the level of the
surface of the water in Suffer lake tChina
slough) to be two and one half feet below
that Of the Sacramento river The borders
of the lake are not particularly clean. There
are large deposits of filthy material, garbage,
etc, on the l street side of the lake. Il
