EnRland's Great Cruiser Less Speedy
Than Uncle Sans Fast Ships.
From the London Times.
The Terrible, cruiser, Captain w. H.
Fawkes which was built and engined by
Messrs J, & G.. Thompson Of Clydebank.
Glasgow, arrived at Spithead on Saturday
night at the conclusion of her steam trials.
and her gun trials are to be carried out
forthwith. At the 1900 horsepower trial
on Thursday and Friday the vessel drew 20
feet l inch forward and % feet 10 inches
aft. The steam In the boilers was 1855
pounds to the square inch, and the vacuum
25S inches starboard and 265 inches port.
With 1924 revolutions starboard and 1OS
port the mean indicated horse power was
Is. 1913 for the thirty hours, and the coal
consumption was LII pounds per indicated
horse power per hour. The speed of the
ship. as taken during three runs on the
measured distance between Rame Head
and DOdman Point, was D,9G4 knots.
Following is the official report Of the
principal four-hours' trial on Saturday:
Draught of water forward. % feet 8
inches; aft % feet 3 inches; steam in boil
ers. 229.6 pounds; vacuum, 26 inches star
beard. 25.9 inches port; revolutions per
minute, liz starbOard, 111.& port: ind1-
Gated horse power-starboard, 12,515; port,
13,O0-total, 25.572; speed of vessel, pal
knots.
At the conclusion of the full-power run.
and when the ship had reached Rame
Head. the eastern limit of the distance the
Terrible started for Spithead. in order to
carry out her four hours 1000 horse
power trial. Drawing the same amount
of water as before, with 225 pounds of
steam iE the boilers and d vacuum OF 26.1
inches starboard and 1854 inches port, the
engines made 1OS.SO revolutions starboard
and 1OS.S6 port. the indicated horse power
being 1882 starboard and II $40 port-to-
tai. 222S3
In the 5000 horsepower trial of the Ter
r!ble with sixteen boilers lighted, the coal
consumption was 2.27 pounds per indicated
horse power per hour, but in the Powerful
1t dropped to 2.O7 pounds. When the latter
ship went on her thirty hours 1s.OOO
horsepower trial with all her forty-eight
boilers in use. and with mean of 1s, ABB
horse power. the consumption was 1.S3
pounds. whereas, in the corresponding
trial Of the Terrible, with s,493 horse
power. it dropped to LII pounds.
In speed both ships have surpassed ex-
pectations, and here. again, the same order
of progression that has been referred to is
to be observed. for while on her first trip
the Terrible gave a speed of 13.43 knots
with 64.5 revolutions, the Powerful subse-
quently averaged 14.34 knots, with 623 rev.
olutions. At the $4,000 horsepower triaf
both ships gave identically the same mean
of speed-20.96 knots-over the measured
distance. but while the Powerful worked at
1851 horse power at this period of her
trial. the Terrible attained the same end
with $500 horse power. Then, at the full
power trial. on November q. the Powerful.
with 2',SS6 horse power. gave a speed of
lis knots. whereas the Terrible. on Sat
uIday, with 25.572 horse power, realized
mean of 2.I knots. Perhaps, however
the tn most reliable test of all was made in
the Terrible on Thursday last, when
record was taken of the speed in a light
run from ST. GATHERINGS to the Lizard
when it was found. with little more than
1900 horse power, she maintained a speed
of 21.O3 knots
