MINING NEWS.

[The following extract from a letter, dated San Fran-
cisco, May 2, 1852, which appeared in the New York
Herald, affords strong corroboration of the statements
put forward on behalf of the Anglo-Californian Gold
Mining Company. It also proves that other associations
are actively, and, we have no doubt, profitably, engaged,
notwithstanding the assertion that no reliance can be
placed upon labourers discharging the obligations they
have undertaken previous to their arrival in the auri-
ferous districts —ED. Sun. J
" Among the many rich leads of which I can speak
from personal observation, is a vein belonging to the Key
Stone Quartz Mining Company. I saw over one dollar
of the 11 carer of gold washed from a pan of decayed
rock, without any quicksilver or other help than pure
cold water. Thu same quartz will yield from forty to
fifty cents per pound upon a careful assay with quick-
silver. The lead is said to be one of the richest in Cali-
fornia. Sir H. V. Eluntly, the president of that com-
pany, is fitting up machinery and preparing to work the
lead upon an extensive scale. In the immediate vicinity
are several large companies, to wit: the Sutter, Colonel
Hagan's, Russell's, &c., with their machinery in readi-
ness to run. Oae thing which has heretofore and still
is retarding the progress and 3,uccoss of quartz opera-'
tions, is the want of sot better mode of amalgamating
than is now in use, and any improvement in this respect
would meet a handsome reward in the region I have
spoken of.—Yours, &c.,
" April 27, 1852. " A. A. BOYDEN.
" P.S. Since writing the above, I have seen a letter
from Mr. William Fitzpatrick, published in your paper
of the 25th inst., in which ho refers to the same mining
region. Having been present and inspected the Key
Stone Mining Company's claim, I can speak more confi-
dently of it, and your readers may rest assured that it
will prove one of the best claims in the State.

'We belif•ve that it is not premature to state that
Sir Henry Lytton Bulwer has been able to bring the Mather
affair to something of a more satisfactory conclusion. Sir
Henry Bulwer has not stirred again the question of pecu-
niary compensation. which has been so much mismanaged,
andles brought so mach discredit upon the British name in
that quarter of Italy, where it was, of all others, requisite
that it should stand high. He has perstrided the Duke de
Casiiiano to agree to a note, not only expressive of the regret
of the Tuscan Government in reference to the past, but also
promising isr the future to recognise the principle of respon-
sibility for all acts relating io British subjects, committed in
the territories of the Grand Duke.—Sunday Paper.
