Rockland, Me-, Nov. 5.-The battle
ship North Dakota having proved her,
self yesterday to be the swiftest of
the big fighting ships of her class in
the world, left the harbor at 1920
O'Clock today to begin her four hours
endurance test. To meet her con-
tract requirements the North Dakota
must average 60 revolutions Of her
propeller per minute during the four
hours, which. according to her show
Ing in her screw Standardization tests
yesterday, will give her an average
speed of twenty-one knots an hour.
The Delaware. the sister ship of the
North Dakota, on her four hours en-
durance test averaged 21.65 knots and
her fastest. speed during the run was
21.68 which was maintained for half
an hour.
The battleship made such fast time
in her four hours endurance trial
that she reached Massachusetts, bay
ahead OF time and at $3.50 .. m. was
heading back to the northeast past
Cape Ann.
The North Dakota is the fastest
battleship of the dreadnought : type
anlOet, as we'll as one of the two most
powerful battleships in the world. Her
! screw Standardization tests over the
tockland measured mile course yes
terday DEVELOPED a maximum speed of
22.25 knots and an average Of 2l.833.
Both marks are in excess of the best
performance Of either her sister ship,
the Delaware, or the eRellerophon. the
leader dreadnought Uf, the British
navy.
In attaining this surprising T1peed,
| the turbine engines of the North Da-
kota were forced to the development
OF more horse power than has been
reached by any battleship afioat. A
maximum of 35,1 $50 horse power was
recorded. while 1886 horse power
was the mean amount. The maximum
number of revolutions of her nickel
composition propellers was 2S6 a
minute. 1t was found that 263 revolu-
tions in this time were sufficient to
maintain the contract speed of twenty
one knots. -,
The North Dakota, by her perform
ance yesterday, takes precedence ais
general first class battleship over
any other afloat. Her sister ship, the
Delaware. which was given her trials
over the same course on October %,
! was In uncertain possession of this
honor by her trial performance but
the figures recorded for the North
Dakota surpass those of any other
dreadnought. There. is: but one such
battieshipN afoat at the present time
whose attainments may exceed those
of the North Dakota. This is the
Neptune, just launched for the British
navy. The Neptune. however, will
have to attain to figures too much in
excess Of specifications to accomplish
this. The Bellerophon of the British
navy has made but 22.1 knots, as COM
pared with the North Dakota's per-
formance yesterday of 22.25.

formances of the North Dakota and
Delaware, sister ships, are as fol-
