[Ry Associated Press. ]

n OCKLAND, Me-, Nov. 4.-The
h North Dakota is the fastest bat
~ tleship of the dreadnaught type
afoat, as well as one of the most
powerful ship in the world.
Her screw Standardization tests over
| the Rockland measured course of one
mile today developed a maximum speed
! of 22.25 knots, an average of 21.S33.
Both marks are in excess of the best
performances of either her sister sh. p,
the Delaware or the Bellerophon, the
festest dreadnaught of the British
navy.
In attaining this surprising speed,
the turbine engines of the North Da-
| kato were forced to the development
of more horse power than has been
reached by any battleship afioat.
A maximum of 35, 150 horsepower
was recorded, while 1885 horsepower
was the mean amount.
The maximum number of revolutions
of her nickel composition propellers
was 2S6 a minute. It was found that
263 revolutions in this time were suf-
ficient to maintain the contract speed
of q knots.
Takes Precedence
The North Dakato, by her perform
ance today, takes precedence as a
general first-class battleship. The fig
ures recorded for the North Dakato
today surpass those of any other
dreadnaught.
But one such battleship is ahoat the
attainments of which may exceed those
of the North Dakato. This is the Nep-
tune, just launched from the British
navy.
The Neptune, however, will have to
attain figures much in excess of speci
fications to accomplish this The Bel
lerophon of the British navy has made
but 221 knots.
Comparisons between the trial per-
formances of the North Dakota and
Delaware, sister ships, are as follows:
North Dakota. Delaware
Fastest speed. d......... 22.25 2l.9S
Mean speed ... 21.S33 21.44
Best horse power.:... 35.150 'S0, 900
Mean horse power 1886 2S,b7S
"Unoffcial
1t was on the first of her runs over
the measured course of one mile that
the North Dakota made her record.
The tide was in her favor and this
is not subtracted from the best figures.
Corrections Made
In the recorded mean, or average
however, the tidal corrections are made
Five trials over the mills course were
recorded as follows: 2225, 21.4S6, 22.13
21.505, and 22133.
The influence of the tide on the ves-
sells speed is shown in comparison
of the time in succeeding miles.
While the five speed runs were being
recorded, the North Dakota was also
undergoing two hours test for con-
sumption of oil and coal. The show
ing is understood to have been satis-
factory
Captain Edward G.. Evans was in
charge of the North Dakota. A work.
ing crew of 400 men pushed the vessel
to her record performance.
Beginning at o'clock tomorrow
morning the North Dakota is to be put
through the second test. a four hour
run at 21 knots. 1t is expected that
an average of about 21.75 knots will be
developed. The run will end off Bos-
ton light where the North Dakota will
anchor and prepare for her "a hour
run at IL knots.
Following this, she will go under
another "a hour test at 19 knots
Within six months it is expected the
North Dakota and the Delaware will
take their places in the van of the
American navy's line of sea fighters
and will then rank as the greatest bat
tleships in commission throughout the
world
