GLEAsINGs FROM THE FOREIGN MAILS.

England.
The completion and trial Of the Britannia tubu-
lar bridge took place ON Tuesday, 9th inst. At
half past six o'clock in the morning, three power
full engines (the Cambria, the 81. David, and the
Pegasus) of from fifty 10 sixty horse power each,
decorated with flags Of all nations and union jacks,
steamed up and harnassed together, started from
the Bangor station, with several gentlemen, who
were carried through the tube at me rate OF seven
miles per hour, with the view of boldly proving,
by means Of dead weight, the cabre OF the bridge
at every hazard. The total weight OF the locomo-
tives was ninety tons. The locomotives We're
brought TO stand-stil in the centre of each Of the
great spans, without causing the slightest strain
detection. The first process-that OF gong through
the tube and returning occupied altogether ten
minutes.
through consisted of twenty four heavily laden
wagons, filled with huge blocks OF Brymbo coal; in
all, engines included, an aggregate weight OF three
hundred tons. This was drawn deliberately
through at the rate of from eight to ten miles an
hour. During the progress OF the train, those
who stood upon its top to ascertain any possible
vibration, reported they could detect no sensible
detection.
An ordeal stronger still was then resorted to-a
train Of 200 tons Of Goals allowed TO rest, with
all its weight, for two hours In the centre OF the
Carnarvonshire tube, and at the end OF the time, on
the load being removed, 1t was found to have
caused a detection of only fourt enths of inch
II is remarkable that this amount of detection is
not 30 much one-half hour OF sunshine would
produce upon the structure; II being, moreover,
calculated with confidence that the whole bridge
might with safety and without injury to itself, be
DETECTED to the extent of thirteen inches These
loads it is most material to remember, i'm
mensely more than the bridge VIII ever be called
upon to bear in the ordinary run Of traffic.
During the trial Of the dead weights very In
tcresting episoda proceeding took place in the in
terror OF the Carnarvonshire land tube; that Of
putting the last rivet into the plates, making ex
actly the 2 900 ,OOOth that have been used.
About twelve O'Clock another testing train was
prepared to be taken through the tube. 1t con-
sisted of the three engines the 200 tons OF COAL and
from thirty six to forty railway carriages, contain
ing between 600 and TOO passengers. As the huge
train trailed slowly through the tube, successive
salvos of artillery were fired at each end.
The public Inauguration for everyday traffic
may be expected on the 18th instant.
The CALIFORNIA GOLD IN ENGLAND.-Amongst
the list of consignees in England of gold from San
Francisco, by late arrival, the name OF Roths
child appears opposite shipment Of some two num-
dred thousand dollars.
New STArUE.-Gibson, the eminent sculptor, is
now occupied in making design in his studio at
Rome for national monument for the British
House of Lords which affords high promise OF beau
ty, and is most rich in poetical illusions. il con-
ssts of the statue of her majesty, supported by two
figures, one representing Wisdom, the other Vic
tory who makes Queen Victorias name speak
really the truth, when look to events which rem
der her reign glorious. On the pedestal are three
bas- reliefs, representing Commerce, Science, and
Agriculture, the triple root OF Britannias unri-
vailed grandeur.
LocoMoTIvE.-We are informed that there will
shortly be brought before the public new locomo-
tive, in which the requirements Of either steam,
fire. air. or water, will be dispensed with; its power
of traction, while effective, will be perfectly safe
by it one half at least Of the present working ex
penses will be saved Mining Journal.
The CoLoNIEs.-From Australia we have con-
tinued complaints Of the conduct of the officers and
surgeons on board the emigrant ships on their pas
sage to southern colonies. Some of the atroci-
ties ar q
ticular cases having been mentioned in Parliament.
Lord Grey promises to punish the parties with the
whole weight of his power. We have no further
from the Cape; but the proceedingsin Parlia-
elected that the bloody proclamatons in Cingalese
were clever forgeries, and the party in the Com
mons, which counted upon proving the complete
guilt of Lord Torrington and the military officers
under his command, have found that the ground
has been cut under them, and 80 the matter will
probably terminate.
