easy distance from town, and in the certainty that if the
sport be net of first-rate character, yet an agreeable day
especial
may be enjoyed on Runnymede. On this occasion, the ele-
ments were, however, unpropitious, and the heavy showers
sadly interfered with the enjoyment of the multitude. The
card did not hold out any great prospect of sport, hut there
were one or two close centeets, and a dead heat for the
Runnymede gave an unlooked for excitement to the pro-
ceedings. The first race for the Betting Stand Plate was
won, after a pretty race, by Bolero, and the King John
Stakes were the hollowest of victories for Mr: Alexander's
good-looking filly by Teddington. For the Runnymede,
Odine was made a very warm favourite at 6 to 5 on her,
and she looked like a winner opposite the stand, but Detec-

tive managed to get up, and a good race between the two
resulted in a dead heat. In the deciding one, Detective
walked over, and the stakes were divided. Mr. W. Beville
cantered in on Devotee for the Welter Stakes, making an
example of his opponents, and for the Ankerwycke, the two
favourites, Reindeer and Fletton, finished first and second.
Her Majesty's Guineas brought the unusual number of 12
to contend for the prize, which was won in hollow style by
Gibraltar. At the conclusion of the race, a tremendous
storm of rain and thunder quickly cleared the course of the
crowds. The attendance was good, though the counter at-
tractions of Stockton detained many professionals in the
North, and the sport was better than was anticipated.
The Betting Stand Plate of 100 soya (Handicap), for all
ages. Winners extra. Three-quarters of a mile.

Gamecock, in company with Deerfoot and Spitfire Kitty,
got away in front, and ran in company to the straight.
where they were joined by the favourite, who took a de-
cided lead as they reached the distance, having Mr. Nel-
son's colt, Deerfoot, and Spitfire Kitty in attendance. Half
way up the latter dropped back, and in a few strides further
Gamecock was out of it, leaving the issue with the two,
Bolero winning cleverly at last by a neck; a length and a
half between the second and third; Gamecock a bad
fourth.

TRIAL TRIP OF TILE AURORA

Since 1810-1, when the screw may be considered
to have been definitely adopted in this country for
both the Roy's' and mercantile navies, there has
been no incident connected with its subsequent his-
tory which has created so great a degree of interest
in the minds of scientific men and the officers of
both services as the introduction of the double, or
" twin" screw principle, each screw worked by in-
dependent engine power. The reason of this is suffi-
ciently obvious to the initiated, although perhaps
not to the general public. The fact is, we are enor-
mously increasing the tonnage of our ships and
their engine power, and, as a natural sequence to
this course, the draught of water of these large
vessels has to be increased in proportion to
their tonnage, in order to fully develope their
screw's power, for, as the engine power
is increased so also increases the diameter
of the screw, and so also must increase in
the same ratio the ship's draught of water. The
natural result of this general increase in size and
driving power is that the deep-loaded merchant
single-screw steamer can only move in certain direc-
tions in narrow and tortuous rivers, and conse-
quently incurs a considerable degree of extra ex-
pense under such circumstances, exclusive of loss of
time, which in the present day is acknowledged to
be of more real value than money itself. Our War-
rior and Black Prince are, and our Minotaur and
Northumberland will be, from their great draught
of water and the great space they require to
turn in, perfectly useless to attack such for-
tresses as Cronstadt, New York, or even Cher-
heurg ; or to run into such a place as Spithead,
passing the proposed marine forts on theNoman and
Horse, and tackle a ship or two inside the forts.
The use of a single screw is, in fact, attended
with so many dangers and difficulties, which may
possibly be avoided by the use of two screws
both in the Royal and mercantile marine, that it
can be no matter of wonder that the subject should
have acquired a degree of importance second only
to the universal adoption of the screw itself in pre-
ference to the paddle. Tee practical introduction
of the "twin" screw principle in this country is
owing to the enterprise of Messrs. J. and W.
Dudgeon, shipbuilders and engineers, of Limehouse,
who, in November last, tried their first vessel fitted
in this way on the Thames, the Flora, of 400 tons
and 130 horse power of engines (collectively), fol-
lowed after wards by two other vessels, the Hebe and
Kste, of about the same dimensions and power, the
trials of which were carried out under the supervision
of Admiralty officials, and were fully reported on each
occasion in The Sun. The success of the trials
were in each instance most unequivocal and satisfac-
tory, and in yesterday's trial of the Aurora, while
the value of the twin screw principle was again de-
monstrated in the most satisfactory manner possible,
it was also on this occasion developed more fully
than in either of the previous trials. The double
screw was adopted by the Admiralty some years
since in the construction of the iron-cased floating
batteries, but they wero driven in those vessels by
collective, not independent engine power ; conse-
quently the adoption of the principle in their case
only enable the Admiralty to construct vessels that
float at a moderately light draught of water, and
carry en immense (for their tonnage) weight of
armour and armament, in addition to the weight of
their engines, but it gave the vessels no increased
powers of turning, or manoeuvring rapidly under
steam in any circumscribed space, which they would
have possessed had their screws been driven by in
dependent engines, as were the Aurora's in yester-
day's trial. It is these increased facilities which
the double independent screws offer to ships
of war for manoeuvring rapidly, whether engaged
with an enemy afloat or with a shore battery, that
has brought the subject so prominently before the
notice of the Admiralty and the general public,
and to these military purposes our report of yester-
day's trial more especially refers.
The Aurora is an iron vessel, 165 ft. in length,
with a beam of 23ft., a depth of 13ft. Gin., an area
of midship section of 150 square feet, and a die-
placement of 400 tons. Her engines have a collec-
tive nominal power of 120 horse, and drive two
three-bladed screws, each independently of the
other, 71t. in diameter, and with a pitch of 14ft. 6in.
The cylinders have a diameter of 26in., and a 21in.
stroke. The Aurora is a smart looking vessel, with
much finer lines forward and aft than were pos-
sessed by either of her predecessors. She carries
two short masts, rigged for fore and aft canvas, and
altogether, although " light as a bladder" on the
water, has the appearance of a thorough steam
" clipper." Her draught of water at starting yes-
terday was 7ft. 3in. aft, and sft. 3in, forward.
A large party of gentlemen left town yesterday
morning by the 10.52 train from Fenchurch-street
tor Tilbury station pier, alongside which the Aurora
lay with her steam up., Immediately on the party
embarking the screws were set to work in opposite
directions, and th© vessel slowed round with her
head down river and started on her trial at
12.20 p.m., under the charge of Mr. Leigh,
Trinity pilot, the wind being strong at S.W., and
the tide at half ebb. In running past the mea-
sured mile, in the Lower Hope, with the engines
not up in the number of their revolutions, she was
timed and found to go ever the ground in 4 min.
8 sec., giving the vessel a speed of 14.516 knots.
At 1.30 p.m. the Aurora was approaching the
Nore Light vessel, the engines averaging 120 revo-
lutions, with 271 b. of steam and a vacuam of 25in.,
and every part working with the greatest possible
smoothness. At 137 the Nore was passed, the dis-
tance from Tilbury, 20 nautical miles, having been
done in 1 hour and 17 minutes, an almost unparal-
leled rate of speed, considering the vessel's horse
power of engine and hull displacement. From the
Nore to the Mouse Light the vessel continued her
course, the wind still fresh from the same quarter,
and the movement of the water which necessarily
accompanied it giving the vessel, from her light
draught and hold upon the water, sufficient " roll"
to detract from the efficient acting of her only just
submerged screws. Notwithstanding this disad-
vantage, however, she ran past the " mile" on
the Maplin Sands in 4 minutes 10 seconds, giv-
ing a speed of 14.400 knots, it being now about
slack water, and the tide of little moment
either way, and accomplished the distance
to the Mouse Light at 2h. sm. 225,, hav-
ing been 28 minutes and 23 seconds from the Nore
--eight nautical miles. During the latter part of
the run doivn a small jib had been set to steady the
vessel, but no other help was given by the vessel's
canvas to her engines in attaining this somewhat
extraordinary rate of speed. From the Mouse the
Aurora was run out between the Maplin and the
Barrow as far as the Swin Light, passing the Jones
Dixon, a fine screw collier under sail and full steam,
with her head in the same direction as the Aurora's
on the way. On reaching the Swin the vessel's head
was brought round end laid homeward, it having been
dechied not to lengthen the trial by making circles,
Se, °Win gtothe high state of the winch the light con-
dttion of the vessel, and the very satisfactory manner
in which she had already turned both to port and star-
board in tins wet to her rudder or screws, proving that
she pose eased the same facilities in that respect as
were pot Isessed by the Flora, Hebe, and Kate, a faci-
lity of rr taneeuvring, in fact, which
mr
and
ad fittedstnece ssarily
be posts( ssed by every vessel built with
double screws driven by independent engines.
South; Intl was passed at 4h. 15m , and about two
miles ithead was seen the Sea Swallow, one of the
fastest. paddle steamers on the Thames, plying be-
tween. London, Southend, and Sheerness, and a hot
chase rsaturally ensued, the Aurora eventually pass-
ing ahe clipper at 4h. 40m. in the midst of a heavy
squall cef wind and rain, and subsequently during
the min up to Blackwell passing everything under
stea.en she came across. Gravesend was passed at
5h..15m., ,the engines making on the average at the
time 127 re volutions, and Blackwall pier, the closing
