was almost precisely what has been calculated and
anticipated, excepting always the allowance to be
made for each engine having in turn to overcome
the resistance offered by driving the paddles or
towing the screw. What, perhaps, was not antici-
pated was the immense accession of momentum
gained by the union of both engines, and which has
now placed the immense speed and consequent
success of the Great Eastern beyond all chance of
doubt.

These trials, with the turnings and slackenings.
they involved, brought the vessel close under the
Smtth Stack Light at Holyhead, which rose in the
now clear sunshine in all its rugged magni-
ficence of light and shadow, its splintered
masses apparently falling to decay, like the ruin of
some island of the olden time. The good folks in
the Stack Light seemed evidently not a little
puzzled to account for what appeared from land to
be a series of most meaningless evolutions. Cer-
tainly to the non-initiated the wayward and eccen-
tric course of the Great Eastern must have looked
unusual, to say the least. The value of the experi-
ments, however, was undoubted, and the results
achieved were on the whole of the most satisfactory
character.

At 3 o'clock the weather had cleared and set in
fine, and the Great Eastern, at last having solved
all the questions which were capable of being
solved under steam in such a narrow channel, stood
in for the harbour of Holyhead. It is not a very
easy place to take a vessel in of the length and
depth of the Great Eastern, but Captain Harrison
had the ship as much under command as a Thames
wager-boat, and moving her easily up to the spot
selected for her, the anchor was let go in about nine
fathoms and the vessel moored at a few minutes to
4 o'clock. Thus terminated, under the most favour-
able auspices, the second trial trip of this ship ; the
whole distance accomplished being 48f1 knots in
about 40 hours, exclusive of the time devoted to
the experiments. This gave an average on the
whole run of a little over 12 knots (15 miles) an
hour, and for more than three-fourths of the whole
voyage the ship was o•-.ly going at half speed.
Fairly estimated, the result exceeded even san-
guile expectations, and Captain Harrison now
feels confident that the vessel may be depended
on to average 14 knots or 18 statute miles .
an hOur, and under ordinary favourable CsifellM-
stances . of summer wind and weather to make
stretches of from 171 to 18 knots an hour: During
the whole voyage the paddles made 23,870 revolu-'
tions, and the screw 81,030. In neither engines
was there an approach either to heating. or noise.
On Monday the escape valve on one of the screw
cylinders of Messrs. Watt and Co. got jammed open
in a similar manner to the screw on Saturday. The
mere accident, if such it may be called, is scarcely
worth mentioning, if it were not for the fact that
peed had to be reduced to remedy the defect. The
question now arises—how long the Great Eastern
will remain at Holyhead, and, whether or no she
will start for America this winter As far as can
be judged from the successful results of this trial
trip it would seem that -the ship is capable of going
anywhere and doing anything. Nevertheless, much
remains to be done in the way of making ready
for an Atlantic cruise, and at present there seems
as little probability of the Great Eastern starting
across the Atlantic this month as of Holyhead
itself.

The visit of her Majesty- is still expected next
week, though whether it will take place on Mon-
day or Tucsday is still uncertain.
