equipped. The pipes were sixteen inches IN
diameter. They had gasoline lamps arranged
near the giants, SO as to enable them to pros
ecute their work during the night. The
banks in the upper mine were about fifty feet
high These banks are Of light material, and
cave and wash readily. It is gravelly, with
a large amount of sand and clay iutermixed.
In the new bank of the southern mine there
was considerable red material near the sur
face. The lower pit. with the exception of
stratum of pipe clay, was entirely gravel. l
know of my own knowledge that all the ma
tsrial of these mines dumped into Canyon
creek. ! made an estimate of the amount Of
material taken from the Gold Run mine
since mining began, and make it 49, 900, 600
cubic yards. This is a low estimate, and all
of this material was deposited into Canyon
creek, and thence into the North Fork. The
canyon descends rapidly. 1t has fall of
more than 200 feet in less than one mile.

eter on the bank nights There is 400 feet
elevation between the town of Gold Run and
the bottom of the pit. Above the mouth Of
the tunnel the canyon has grade of perhaps
thirty or forty feet to the mile. There per-
haps are 800, 600 yards of deposit on this part
of the canyon. Below the mouth of the
tunnel the channel of Canyon creek is swept
perfectly clean. l have a sample of the water
which was taken from the mouth of the tun-
mel when the mine was in operation June Is,
1881. Here the witness exhibited some fear
fully muddy water, one. eighteenth of which
was solid matter. The appearance Of this
water would make person shudder who
is used to taking Sacramento straight. ]

the canyon and thence into the river. Just
above the point where Canyon creek comes
into the North Fork the river contained
about 11,000 or 1900 inches Of beauti-
full clear water. As coon as the waters of

waters Of the latter became muddy and pre-.

| tanned fourteen per cent of sediment, and
| six miles down the river l found that
| the water in the river contained three
per cent. This reduction wss caused by
| the sediment being scattered through a
much larger volume of water. l visited

and with Mr.. Huntley examined the river
on that day at that point. The next day We

the river, travelling partly in its bed, and
partly on its banks during the whole route.

were not in operation. The mine was in q

on this expedition. Found no deposit tc

the mouth of Canyon creek is quite uniform
These bars in the first ten miles were all Of
the same nature-cobble, gravel and coarse
sand. The bed of the river was hard-iike 8
cobble pavement, and was safe fording

posts of slickens were found, which wert
soft and sticky, and had to be avoided. II
the canyons it was easy to perceive how high
the freshets rose during the winter. The
water.worn rocks on the sides plainly indicate
the hight Of the floods. The velocity of The
North Fork from Gold Run to its junction
with the Middle Fork will average abou
three miles an hour. The following is tn.
