THE ROYA i; MAIL STEADIER SEINE.

On Saturday s another magnificent addition was
made to the Ro y al Mail Company's fleet, their new
steamship Sein, e, commanded by Captain Robert
Revett, then in a king her official trial trip to the
perfect satisfactiie n of the Government authorities.
This noble vesse 1 , which is a sister ship to the ill-
fated Paramatta. and the more fortunate Shannon,
was built by tile Thames Iron Shipbuilding Com-
pany. Her pri nu .ipal dimensions are as follows
ft. in.
Length bet WE 'en perpendiculars, 330 0
Length over • : all, 339 0
Length on 1 o adline, 328 0
Breadth of lal lam, 43 91
Tonnage (1)1 i ilders' measurement) 3,092 54-94
Area of mids J tip section, 777
Displacemel t, 5,180 tons.
The boilers and Athering paddlewheels have been
constructed at 11 to Royal Mail Company's factory
in the Southern iv ton Docks, under the superinten-
dence of Mr. 11( ert Ritchie, their superintending
engineer. The b oilers are tubular, and have been
built with gre. I,t care, in order to produce the
largest quantity o f steam combined with economy
of fuel. They .ve been fitted with superheating
apparatus design e d by Mr. Ritchie with a view to
increase the eco a omical results, and its perform-
ance has justified, the Expectations formed of it, as
the steam was si aj ,erheated to 388 degrees during
Saturday's trial, a nd at full speed of the engines
the safety valves - t,vere strongly blowing off. The
engines, which a ri •re constructed by Messrs. Sum-
mers, Day, and C ~, of the Northam Ironworks at
Southampton, are • of 800-horse power, on the oscillat-
ing plan. They a re the largest oscillating engines
ever made in Eha rope. The cylinders are of 97
inches in diamett , and 10 feet stroke, while the
paddle-engines i, a the Great Eastern are only 74
inches diameter, tz td 14 feet stroke. The castings
necessary for engi a es of such enormous size were, as
may be imagined, on the largest scale. The Seine
left the Southern] at '.on Water about 11 o'clock on
Saturday mornii it T, and proceeded at once to
Stoke's Bay, v v.b ere she ran the measured
mile four times, and was subsequently taken
down the Sole at towards the Needles, then
rounded to, retur ;rig to the docks shortly before
sin the afternoon._, There was a party of nearly
200 persons on be at d, including a large number of
ladies and gentl. sin en from London. On the re-
turn home the c( m Tarty sat down to a sumptu-
ous banquet in tl to spacious saloon, under the
presidency of Ce t itain Mangles. The trial of
the Seine was m .de under very unfavourable
conditions, as the wind was blowing half a gale
from the S.S.W the force, according to the
Admiralty gauge,, being between 0 and 7 ; and
the Government fe athorities at Portsmouth had
the same mornir ig refused to take one of their
ships to the mea aui ed mile. Notwithstanding finis
disadvantage, tl to average speed attained by the
Seine was 14.11 15 knots per hour, equal to 161-
statute miles; a id in the opinion of practical men
on board anothi knot might be added to compen-
sate for the unf tvaurable weather and the bad trim
of the ship. T he four runs on the measured mile
were made as fo Llows
