These are both admirable no doubt 10 their way the

fast paddle steamers with few, against heavy sailing
ships with many guns, has by common consent been

THE AMERICAS CAMFLs IN UsE.-Thhty two csmels
brought from Smyrna, in the United States storeship
Supply together with two bonn on the passage, were
safely landed on May l3 at Indianola in Texas, and
have since been put in USE to some extent in carripg
Government stores to the great terror of the horses
and mules ard the equal delight Of wonder seekers in
that vicinity Most of them have shed their hair

are represented in perfect health aud spirits. The
dromedaries. nine ia number, are designed for lex
press, and the cames for slow freight trains scross
the great dry and roadess plains and praires of the
South-west They are accompanied by two Turks
ard three Arabs, and carry loads walk As

probably soon be indicated whether these oriental
monsters can be made of any material service on this
continent
WRouGHT IRov Truss BRiDGE.-Gen Thos. w
II Mosey has lately constructed a bridge at Coving
ton, Ky, the supporting part of which consists en-
,r,y of tubular arches Of wrought iron with light tie
rods acIoss the chords The tubes are triangular and
are made Of double boiler iron. The plates are dis
uosed in such manner the middle of the extension
mates covers the Joints in the interior ones, that no
strain is thrown upon the rivets but the edges abut
fair against each other. The bridge is 90 spsn and
the rise or spring is l2 feet, being segment OF a
circle % feet in diameter. The roadway, OF noer, Is
10 feet WIDE sufficient for two tracks there being three
of the trusses dtscrbedone at each end, one IN the
cepter-the whole OF which, including the tubular
arches, the iron beams which support the roadway,
and non ties weighs about three and halt tuns.
