240 NOVEMBER 2, 1872 GRASS VALLEY UNION
The funeral services of the late William Sweet shot on Tuesday last at Underwood’s ranch, were
held in the Episcopal Church yesterday afternoon, Rev. Mr. Anderson officiating.
INQUEST.—Henry Davis Esq., Justice of the Peace, held an inquest last evening to inquire
into the cause of the death of William P. Sweet. We will give in tomorrow’s paper the result of the
Coroner’s investigation.
PERSONAL.—Hon. A. A. Sargent visited Grass Valley yesterday. His health seems to be reestablished and he is very cheerful. We don’t think his cheerfulness arises from any hopes he has
of Grant’s re-election, but from natural good feelings. He ought to leave for Washington before next
Tuesday—something may be going on there to which he should attend.
North Bloomfield Gravel Mining Company.
The Nevada Transcript of yesterday says:
During the past year the North Bloomfield Gravel Mining Co. have extended their
enterprise until now they employ 450 men, and they expect to add considerably to this force
for the purpose of extending their ditch down into Bridgeport township. The operations of
this company extend from Bowman’s dam to Lake City, and they have given life and energy,
more or less, to the business of every mining camp within the range of their operations.
They now have 150 men employed at Bowman’s, and the dam will, it is expected, be
completed in two weeks. Their ditch conveys water from this dam to the township of
Bloomfield.
The most important work of the company now is the bed rock tunnel, which is to open
the basin or channel at Bloomfield. This channel was opened to the bed rock 208 feet, and
found to contain pay gravel from the surface down. The company having ascertained this
determined to run a bed rock tunnel from Humbug cafion to their claims, that sufficient
fall might be obtained to work to advantage. The surveys were made by Hamilton Smith,
Superintendent of the company, and the work commenced about the first of last May.
We have recently passed over the line of works, and a description will be interesting to
our readers. The tunnel will, when completed, be 8,000 feet in length. The mouth of the
tunnel is 440 feet lower than the channel, and will, at the upper end, be about 75 feet lower
than the gravel. A road was built by the company along the line of the tunnel, and eight
hoisting works put up, numbered from one to eight inclusive, coming from the mouth of the
tunnel. They are all built on the same plan, and are run by hurdy-gurdy wheels. The power
is supplied from the company’s reservoir, through 10,000 feet of iron pipe. The shafts are
double and sunk diagonally with the line of the tunnel, in order to give the greatest possible
width for working on the faces where the shafts are completed. The works are about 900
feet apart; and in all of them they are now sinking, and at the same time running the tunnel
from the mouth.
No. 8 is on the rim rock of the channel, and No. 1 the nearest to the tunnel mouth. As
we said before, work was commenced in May, the works completed, and much already has
been accomplished. The shafts vary in depth from 178 to 195 feet, and the tunnel has been
run 235 feet from the mouth. About 720 feet in the aggregate has been completed out of
a total of 1,550 that must be completed before the line for work upon the tunnel will be
reached. When this is done, the tunnel will be run from both faces, in each shaft, and also
continue work in the tunnel. It is expected that the entire work will be completed in the
Spring of 1875. This is to day one of the most extensive mining operations on the coast, and
the work is being done systematically and thoroughly. The channel to be opened is rich, and
the bed rock has only been reached for prospecting. This company deserve credit for their
enterprise, and we hope that the highest anticipation of the company’s managers may be
more than realized.
