Tin mines have been discovered in Madison
county, Missouri, near the famous Pilot Knob. A
company has been formed, who have opened a lode
and extracted some small parcels of ore. The tin
crops out from the hill side, giving every facility for
working, and the metal yields from 4 to 15 per
cent. A reward of $lO,OOO was long ago offered
for the discovery of a tin mine, and it is believed
that the United States will derive great advantage
if the mine proves as rich as anticipated. Professor
Nathan H. Parker has reported on this discovery,
and Professor Beauregard has furnished an analysis,
of which the result is as follows :
" Having pulverised one pound five and a half
ounces of ore (tin stone), gathered from the surface
of the lode, and selected from different places, I
united with this ore four ounces of two chemical
agents necessary to facilitate the idisagregation' of
the mineral from the granite and other foreign
matters. After having composed this mass to a
white heat for two hours, in a German sand-pot, I
obtained the following result :
" 11 grains of pure white tin.
"17 grains of pure black tin.
" If we take into consideration the difficulty aris-
ing when extracting a metal so oxidable, and the
loss of which is not less than 20 per cent. from using
a new pot (or crucible), the results of the assay are
certainly very satisfactory."
The Iron Age saya that the importance of the
as the one mineral in which the
dis-
covery is much greater than its money value would
States was hitherto deficient. For the fiscal
indicate, as being
year ending June, 1866, England received in gold
for tin plates $6,097,609, and for blocks, pigs, or
bars of tin for the same period, $1,993,361.
The steam yacht Quaker City arrived at Con-
stantinople from Italy, with 66 American ex-
cursionists, on Saturday last.
On Wednesday, 31st July, the monitor Onon-
daga left New York for France, having been sold
to the French Government. When outside Sandy
Hook she encountered a gale of wind and was com-
pelled to return in distress. She was built by Mr.
Rowland, the iron plates being fixed on the hull
without the usual backing of wood. Two large
centrifugal pumps were placed on board, supposed
to be able to pump her clear of water in an hour,
even if full. For some reason or other they did not
act as anticipated, and as water gained rapidly, for
a short time she was in danger. The Dunderberg
made a trial trip on Friday, Aug. 9, in charge of a
French crew, with Admirals Paris and Raynaud on
board. There was a little delay in consequence of
the ignorance of the French firemen in Using an-
thracite coal, but when the fires had been kindled
the performances of the Ship gave great satisfaction.
Last Saturday she was taken into the basin at
Cherbourg, where there is no dock sufficiently large
to receive her without alteration. Her exact di-
mensions are as follows:—Extrem:3length, 380.0 ft. ;
extreme beam, 72.10 ft. ; depth of main hold, 27.07 ft.;
height of casemate, 7.09 ft. ; length of ram, 50.00 ;
draught when ready for sea, 21.00 ; displace-
ment, 7,000.00; tonnage,
5,090.00 ; weight of iron
armour, I,ooolb. Mr. Webb, it is said, has cleared
$700,000 by thus safely delivering her to France.
The barritie Plato, with the Fenian expedition
on beard, returned to New York on the 28th
July, and .gave the following account of the
cruise. On the 27th of April last this vessel, of
500 tons register, with 350 picked and well-armed
men, left America to liberate Ireland. She was
spoken off Newfoundland by a British man-of-war,
when she displayed American colours. On the 23d
May, having received a supply of fresh water and
provisions from the Isleasi..Torry; she proceeded to
the Kinsale Head, where she was informed a man-
of-war was cruising. On learning this she put to
sea, where she remained several days before run-
ning into Bantry Bay. After communicating with
the shore, they leit the Bay and landed a party on
the 6th June, who were captured at Wexford. On the
9th, at Antrim Bay, they received an account of
the Wexford affair. A descent upon Antrim was
then discussed, from which their friends on shore
dissuaded them. After remaining some time at
Antrim they proceeded to Belfast Lough, where
several consultations were held with Fenians on
shore as to their chanus on heading an insurrection.
On all sides they appear to have been strongly ad-
vised r.ot to attempt it ; therefore, after cruising for
a few days more on the coast, they returned to the
United States. They state that they communicated
freely with their friends in Ireland
.by means of
signal rockets.
A curious case has arisen under the Reconstruction
Act. General Sickles issued an order forbidding
judges in his districts to entertain suits for matters
which had occurred from the 19th December, 1860,
to 15th May, 1865. Lieut.-Colonel Frank, command-
ing the post of Wilmington, interpreted t his order to
extend to the decisions lately made by Chief Justice
Chase in North Carolina. United States Marshal
Goodloe, of North Carolina, reported to Attorney-
General Stanberry that the process o!'.! the United
States Circuit Court, shortly since held by the Chief
Just ice. at Raleigh, was obstructed by the Colonel's

order on the plea that the cases decided were within
