HA YTI AND A AN DOMINGO.

The Haytians at present in Paris, who consider
themselves well informed as to what is passing in
their country, have addressed the following letter
to the Debats

" It is not true, as stated in the telegraphic de-
spatch of the 6th inst. from Cadiz, that the Hay-
tians have invaded the Dominican territory. The
latest true intelligence from Hayti is that the
Dominican Generals Cabral, Sanchez, Valentine,
Bayez, and others, not long since exiled from
Santo-Domingo by Santana, all ardent parti-
sans of Dominican independence, had suc-
ceeded in joining the disaffected popula-
tions. A serious and extensive insurrection had
taken place under their direction ; the towns of
Lamottee, Neybe, Cerca, and San Juan, had raised
the Dominican flag and energetically protested
against the Spanish occupation. They declared
that, if annexation were inevitable, and they must
cease to be independent, they would prefer to be
incorporated with the Haytian republic. In pre-
sence of these grave manifestations, the Haytian
Government, at the departure of the last mail, was
maintaining an attitude of observation. The few
Haytian troops which, as a measure of prudent
precaution, had been stationed near the frontiers,
had not advanced a step beyond them."

THE MOOLTAN STEAMER.

SOUTHAMPTON, THURSDAY.

The official trial of this vessel, the last new ad-
dition to the Peninsular and Oriental Company's
fleet, took place to. day. She left her moorings at
11 30 a.m., drawing 18 ft. 10 in. water forward,
and 19 ft. 2 in. aft, and proceeded down the South-
ampton Water and through the Needles passage to
about four miles beyond the Needles, when she
turned round, and arrived in the docks at 4 5 p.m.,
thus running a distance of 56 nautical miles in 4
hours 35 minutes, or at the rate of 12 1-34 nautical
miles per hour, the tide being favourable for one
hour only. Taking into consideration the small
proportion of horse-power to tonnage, this result
was considered to be very satisfactory, The Mool-
Itan is 2,400 tons burden, and 400-horse power, 370
feet lone., 31 feet deep, and 39 feet wide. Owing
to there being a stiff breeze blowing, the maximum
speed at the measured mile was not taken on this
occasion. The machinery worked admirably, re-
alizing an indicated power of 1,600 horses, or four
times the nominal power. Revolutions of screw 54
to 56 per minute; vacuum in the condensers (sur-
face-condensers, on Hall's principle) 262 to 27
inches. The consumption of fuel during the trip
was rather less that 21b. per indicated horse-power
per hour,—a performance highly creditable to the
constructors of her machinery. The Mooltan is now
fitted with a three-bladed fixed screw, 24 ft. 3 in.
pitch, and 16 ft. diameter. Her engines are super-
heating, on Mr. A. Lamb's patented principle.
All the latest improvements in machinery, &c., are
introduced into this noble vessel, including a num-
ber of useful and ingenious inventions which have
been already detailed in The AS'un on the occasion
of her run round to this port from the Thames.
The cooking apparatus for the saloon passengers
an;l officers, fitted up by Benham and Son, of Lon-
don, is very complete and compact. It includes five
ovens, a large hot-water and steam boiler, a spaci-
ous hot-plate, steam-kettles, &c., affording accom-
modation for cooking dinners for 200 or 300 persons,
including the pastry and the confectionery, as well
as for baking bread, while the temperature of the
gallery is hardly above that of a kitchen ashore, A
party of about 60 gentlemen sat down in the saloon
to an excellent thjeuner, the tables being kept plenti-
fully supplied with ice frozen in large blocks by the
aid of the steam machinery. Among the company
present were Capt. Patey, the Admiralty Surveyor
of Packets at this port ; Mr. llinnan, Engineer Sur-
veyor to the Admiralty; Messrs. Ruble and Murray,
Board of Trade surveyors; Mr. Peter Rolt and
Capt. Ford, of the Thames Iron 17ompany, who built
the vessel; Mr. E. Humphreys and Mr. C. Tennant,
constructors of her machinery; Mr. A. Anderson,
Mr. J. Allen, Capt. Nairne, and Mr. de Salis,
directors of the Peninsular and Oriental Company ;
Capt. Engleclue and Mr. A. Lamb, the general and
engineering superintendents at this port ; Mr.
Justice Haliburton, M.P., Dr. Beattie, Dr. Finch,
Sir Charles Bright, Mr. Angier, Gen. Tchneiv_esk.x
(of the Russian Admiralty), Mr. C. A. Day, Ml%l
Summers, Colonel Burnaby, Mr. Pinnock, Capt.
Graham, &e. The Mooltan is commanded by Capt.
E. Cooper, the senior commander of the company's
fleet.
