MINING IMELLIGENCE.

Mr. Cronise gives the following returns of some
of the leaditig mines in California :—" The total

$3,725,000. The quartz raised monthly now is
1,800 tons ; the average gross yield is $2O 04 per
ton ; the expense, $6 04 ; and the net yield,
$l4. The total monthly product for 1867 was
$36,000 ; the net earnings for the year, $302,400 ;
the net estimated value of the ore in sight
at the end of the year, $BlO,OOO ; the total
vertical depth of the deepest workings from
the surface, 1,049 feet. The gross yield of
the North Star for four years ending December
31st, 1866, was 842,000 ; net earnings for five
years ending December 31st, 1867, $375,000. For
six months ending December 31st, 1867, the yield
was $110,545 84, and the profits, $20,000. The
Eureka Mine, at Grass Valley, in the year end-
ing September 30, 1865, took out 11,375 tons
of quartz, the average gross yield per ton being
$45 83, and the expense of extraction and re-
duction $l3 75. The production of the year
was $521,431 41 ; the total expenses, $192,648
44 ; the net profit, $327,782 77. For the year
ending September 30th, 1867, the total net yield,

gross, and in the six months ending December 31,
1867, produced 3,500 tons, yielding 100,000 gross
and $27,000 net. The Banner Mine at Nevada,
in four months ending December 31, 1867, pro-
duced $67,512 72, the quartz averaging $23 74,
and in three years ending at the same time yielded
$207,949 66, an average of $2O 34 per ton."

Gold has been discovered near Laramie, on the
Uuiou Pacific Railroad. It was found in Moore's
gulch, 35 miles to the S.W., in the Medicine Bow
Range of the North Platte slope. Mr. St. Clair,
the discoverer, who is sanguine of the value, is an
old California miner. Only surface prospects have
yet been made, and plenty of good colour is obtained
from half an ounce to an ounce being extracted
from the loose dirt by washing in pans. The bed
rock is from 7 to 18 feet below the surface, and
large results are expected when it is reached, as Mr.
St. Clair asserts that they are the best placer dig.
gings found for ten years.

RAILWAY INTELLIGENCE.

Pennsylvania claims to possess a greater length
of railroad than any other State in the Union. In
round numbers she possesses four thousand miles
to New York's three thousand, or one mile of rail to
every square mile of her territory.
The San Francisco Bulletin says :—The railroad
race for Salt Lake is becoming exciting. The Union
Pacific has reached a point 700 miles west of o.ualia,
and has 20,000 men at work on the line to S.►lt
Lake. The Central Pacific is completed over 200
miles east of Sacramento, and has over 9,000 men
at work, with the advantage of a more level coun-
try. General Case, chief engineer of the Union
Pacific Railroad, is now making the final survey
and location of the north end of the line.

There has been filed in the Secretary of State's
office the res)lutions and order of increase of the
capital stock of the Central Pacid-.., Railroad Coin.

The iron bridge on the line of the Catasauqua and
Foglesville Railroad is the longest iron structure of
the kind in the United States, the extreme length
being 1,165 ft., and height 90ft.

The extension of the Chicago, Rook Island, and
Pacific Railroad, from Des Moines, is being pushed
rapidly. By the Ist of September the road will be
in operation 52 miles west of Des Moines, and,
with good weather i❑ November, the managers ex-
pect to have the road graded to Omaha. It is said
that the large earnings of the company will pay a
great proportion of the expense of the extension
and its equipment, and leave therm with two mil-
lions of dollars on hand to be divided among stock-
holders.

The Michigan Southern and Northern Indiana
Railroad Company report for the year eliding
February 29th, 1868, their net earnings to be
$1,880,831. After payment of interest, rent, taxes,
sinking funds, So., 'there remains $849,751, which
would yield 7i per cent. to the common stock, after
paying 10 per cent. on 5,868 shares of the guaran-
tee 1. The expenses have been reduced from 65i
per cent. in 1866 and 1867 to 601- per cent. in
1867 and 1868, while, daring the same time, the
supplies have been increased to $78,809, a result
quite unusual in railway reports when expenses
are reduce]. The road is in fine order, its track
and equipment being equal to any road in the
West.

The new line of railway between Suez and Alex-
andria via Azazieli was opened last Tuesday, and
passengers by the next Indian mail will proceed by
that route, which will take only ten hours, includ-
ing stoppages.
Railroads are making good progress throughout
Maine. The contracts for the grading of the Knox
and Lincoln Road have been made, and the work

is to be finished by the middle of June, 1870. The
European and North American Railway is pushed
rapidly, and trains will be running to Lincoln by
January next.
