NAVAL INTELLIGENCE.

PORTSMOUTH, SEPT. 1.

this morning, before seven, and sent to London by the
South Coast Railway, in charge of the Messrs. Casher.
The Daedalus has now (5.30 p.m.) crossed royal yards
and hove short. . She will be under weigh this evening,
Thertr
on her return toDevonport, to be paid off.
A large American paddle mail-packet passed through
Spithead, having " Franklin " at the main,

We have been visited with a complete deluge, the rain
from 9 a.m. .9 to 5 p.m., coming down in torrents,
without cessation, and so dark as to cause several of the
tradesmen to light their gas—a very unusual occurrence
in the country ; nor do we remember it ever having
happened before at this port.
The Prince of Wales, Indiaman, left at daylight this
morning, for Calcutta.
An American liner, from the river, has just brought
up at Spithead, to embark passengers and stores from
Lloyd's agents, the Messrs. Garratt and Gibbon.
Sinbad, lighghter, Follett master, sailed to-day with
stores for Portsmouth and Woolwich.

CHATHAM, SEPT. 1.
Sir James Graham and the other members of the
Board of Admiralty left Rochester at half-past eight
a.m. this morning, by the Vivid, steam-vessel, for Sheer-
ness. Their lordships, last evening, gave a grand din-
ner at the Crown Hotel, Rochester, to all the princi-
pal officers, both naval and military, belonging to the
several departments at Chatham. After their lord-
ships have made their general inspection of the dock-
yard at Sheerness, they proceed to Harwich in
the Vivid, as we have before stated, to view the
harbour making there for the safety ofiarge-class ships.

PLYMOUTH, SEPT. 1.
SECOND TRIAL TRIP OF THE ST. JEAN

D'ACRE.
The morning yesterday was beautifully fine as the St.
Jean d'Acre moved off from where she had been moored
near the Breakwater for the night, and proceeded on her
second trip. At 10.5 she passed the Lighthouse at the
western end, and was steered the usual course for the
Eddystone. This run was occupied with expansion ex-
periments below by the engineers, and was not noted as
a trial of speed. The ship's head having been turned
towards the Breakwater, the time was noted passing the
Eddystone, and the run to the Breakwater light was
effected in 53 minutes, which, estimating the difference
at 10. j knots, is equal to 11.604 knots per hour ; taking
the distance as estimated by some at 10'11 nautical
miles, the rate would be 11.446 knots. The average
revolutions of her engines was 59 per minute, and ave-
rage pressure of steam on the boilers 181 b. per square
inch. When the pressure on the boilers was 201 b., the
revolutions of the engines reached 61 per minute.
This run was before the wind with no sea, the force of
which was about four. On turning the ship at full speed
outside the Eddystone, she came round in eight minutes,
which was remarkably quick for so large a vessel. Cap-
tain Keppel determined on passing the Breakwater light,
to see what his ship was capable of, and she fully satisfied
all expectations, passing the eastern channel to resume
her work with all the ease of a steamer accustomed to
the port.

which had freshened to a force of six, presenting a re-
sistance of eight against the ship at her then velocity.
The rate by log was nine knots when the revolutions were
54k, and steam 161 b. per square inch, and the rate per
hour on the whole distance was 8.538 knots.
It was slack water on the trial before the wind, but
the tide was setting in on the trial against, and was
therefore opposed to the presumed rate of the ship.
On the whole, the rates deduced from the observed
distances seem to bear out the rates taken by common
log. When we consider, therefore, that the machinery
