MINING STATISTICS.

POLBERRO MINES NEw ADVENTURE.—Commenced
in 1848, sad divided into 2,000 sham, of which Lew were
appropriated as free shares to the then existing clsimuts on
the concern, and 1,000 were new or preferential shares of
131. each, the preference consisting in the right to T.-pay-
ment of the 151. per share beture a t.ivision of profits with
Me other 1,000 shares. Conducted on the cost principle,
under the management of Mr. John Taylor, jun. The
mine. are situated close to the sea, near St. Agile., in CL,rn-
wall, and arc productive both of tin and copper. Having
bun worked for a considerable time, and at great cost, by
the old adventurers without any profitable result, the
arrangement above indicated was come to, and the works
have since been prosecuted with vigour. Hitherto, how-
ever, the mines have not proved so productive as
expected, and the fall In the price of tin has se-
riously affected the amount of the Yasuo', which
have to be obtained from a large quanti,y of
sluff, by very perfect and costly arrangements for
stamping and dressing. The cutlay pr.vions to the re-
newal of operations amounted to 6,7451. 51. 51., to
satisfy old debts due to merchants and others The
mines have produced, from September, NA to De-
cember, 1349, inclusive, 406 tells of tin ore, and 48 toes of
copper ore, which sold for 17,7011. 13s. 10d. The working
costs and lord's dues amounted to 23,7681. lfes. 11.1., show-
ing a balance of expenditure of 6,0671. 3s. 14., which, added
to the first costs, alms mentioned, shows a total outlay of
12,8121. Si. 6d. At the general meeting of the adveriturers
in Apra las', it was determined to auto: rise a further call
on the wh: le of the shares, for the purpose of draining and
working the old Polberro mine, which is upon a distinct sett
of lodes, upon the northern and north eastern portion of the
setts. The engine has since been repaired and set to work,
the mine drained to the depth of 60 fathoms below the adit
level, and the bottom of the mine will soon be reached.
Three levels are now driving upon the copper lode, and the
appearances are very encouraging. This concern, although.
not yet profitable to the sp. ' d adventurers, has afforded
constant employment to 509 persons, and has conferred great
benefit on a barren district of Cornwall.

IRONMASTERS' QUARTERLY MEETINCI.-WOLVER-
Rametow, JULY 10 —The usual quarterly meeung of the
ironmasten of this district has been held here to-day; the
attendance was not numerous. and the business transacted
was very incontiderable. Vary few orders given, and
although some of the large makers state confidently that the
trade is rather firmer, and the present priors can be well
maintained, it is doubtful whether they will be borne out
by the fact ; needy makers, compelled in many instances by
the condition of their tenancy to produce, must cell at some
price, end the demand at the present moment being limited,
only an increase of it can ensure for the trade anything like
healthiness. The nesting at Birmingham tomorrow may
disclose more precise results, but judging from actual cis-
cemstances, the inclination of prices is rather downward
then oherwise. It is proper to state, however, that the
stock of iron is not large, the make having been as muck as
possiblerestricted daring the lest three mouths.

TDE OLD DIVIDEND Bootie IN THE BANK.—A
separate set of offices is neoesssry to keep all such accounts,
and these stock Wipes contain the most varied and extensive
collection of autographs extant. Those whom Fortune en-
titles to dividends must, by themselves or by their agents,
sign the Stock books. The lest signature of Handel, the
composer, and that upon which Henry Fauntleroy was
condemned and executed, are smoog the foremost of these
hoe". Here, standing in a great long building of divers
mortal, looking dimly upward through iron gratings,
and dimly downward through iron gratings, and into
musty chambers diverging into the walls ea either hand,
you may muse upon the National Debt. All the sheep
that ever came out of Northamptonshire, seem to have
yielded up their skins, to furnish the registers in which its
accounts are kept. Sweating and wasting in this vast silent
library, like manuscripts in a mouldy old convent, are the
re of the dividends that are, and lave been, and of the
dividends unclaimed. Some men wculd sell their father.
into slavery, to have the rummaging of them old volume..
Some, who would let the Tree of Knowledge wither while
they lay contemptuously at its feet, would bestir themselves
to pluck at these leaves, like shipwrecked mariners. These
are the books to profit by. This is the plain for X. Y. Z. to
hear of something to his advantsge in. This is the lend of
Mr. Joseph Ady's dreams. This is the dusty fouutain
whence those wondrous paragraphs occasiona:ly Bow Into
the papers, disclaim' how a l•bouring thatcher ku come
into a hundred thousand potrede—a long, long way to come
—and gone out of his wits—not halt so Pa. to go. Oh,
wonderful Old Lady ! threading the needle with the golden
ere all through the labyrinth of the national debt, and
Wing it in each dry harstacke as are rotting hut :
