CALIFORNIA.

Dates from Sin Francisco, to June 1, state that
trade had suffered a little from the fire which bad occurred

- ..... -
on the 4th of the previous month. Dealers bought but
small quantiti, s, jutt sufficient for present supplies.
EXCHANOWC—BiIIs on England, short eight, 430. and
49d. ; France, 51r. ; United States, par, three days' sight.
The interest on money is 2 per cent. per month on good
security.
The total export of dust, according to the clearances at the
Custom-hoagie, from the Ist October, 1849 (before which date
no entry was made), to the 28th of May last, has been
8,845,952 dole ; to this we may add 2,203,000 dole. to be
taken away by the mail steamer to-day. Of the amount of
dust exported as above (per Custom-house clearances)
8,616.814 dots. went to Panama; 319,138 dole. to Clatit 1 i e.
289,138 doh. to Valparaiso, and 30,000 dole. to Talcahuano—
port of Conception in the south of Chili); and 10,000 dole. to
Peru. To the amount of exports cleared we may add as
foibles:—Taken away by private parties in their luggage
and about their persons (which is reckoned at about
330,000 doll. a month, although I think the eetinante Liw),
would give in the eight months—October to Mey-
-2,800,000 dole.; add also amount taken by the vessels
trading to Sow h America (captains and paesmeers seldom
"clearing" their gold) in the same period, 500,000 dole.;
and the quantity taken in the same time by men•ot.war
500,000 dole.; and the whole will give an export of gold in
the eight months of 14,845,952 dole. This estimate is rather
under than over the mark.

Respecting the imports of bullion during the same period
of eight mouths—October to Mar lest—there is much
greater uncertainty. According to the manifests pr. s.nted
at the Custom-house, the value of the imparts of bullion
(In coin of all nations) is only 1,337,331 dole . of which
1,235,331 came from Panama, mid the remains 102,000 (rum
Idelica. What the customs call "declared" amount cf
imports is not one•tenth of the amount " brought here."
The is none at all "declared" as brought from South
America, I mean Peru and Chili, although large amounts
have come (rem Chili ; and again the sum " declared" as
from Ms air° does not amount to a tithe brought by gam-
biers alone from that country. • . . _

The tax of 30 dole. a month per man upon foreign miners
had canted much dissatisfaction among that numerous and

hardworking body. The tsx is undoubtedly high. and as
it eanno• be reduced until the legislature meet next January.
the trade of the southern mining disttict (Stockton) will
suffer severely.
The price current presents none of those exorbitantly high
prices which at one time made it a document of no ordinary
interest.

SUNDAY UTTER CARRIERS.—Some of the pass-
engem, when they arrived at Southampton on Sanday last.
by the excursion train from London, immedistcly sent off
two starrier pigeons, with noses announcing their arrival safe
from railway accidents. The pigeons, as soon as they were
let go, ascended over the town of Southampton, and for •
few mements, they kept darting towards all points of the
compass, and revelling apparently in the sunbeams that were
playing on Southampton Water. In a very short time,
however, true to unerring instinct, the, flew t!ff rapidly in •
north-easterly direction :owarde the metropolis.
THE NEM SUNDAY POSTAL REGULATIONS here
instentoesly multiplied human labour on the Sabbath day.
All the common Barriers sending their goods by railway were

poet, and it often happened that half a s n h dupli-
cates were delivered, in various towns in the kingdom, by a
single postmen. It is necessarythat these bills of parcels
should be delivered on Sunday in order that carriers may
commence work a: five cc six o'clock on Monday inotning.
Blues the late postal regulations, the carriers bare had theta
duplica'es sent by rail, and every Sunday all the c .rricrs ate
obliged to send each • man to fetch them, so shat it often
baptisms that where one platman was formerly employ..,) on
Sundays, six earriers' servants are now empleyed instead
