THE NAMES TRIAL.
Her Engine We're Tested Yester-
day
IN A FOUR HOURS RUN AT
SEA.
She Developed More Than the
Necessary Horse Power and Acted
spIendidly-Her Speed Was Over II
Knots-The Board of Engineer De-
lighted With Her Engines.

New York, October 1.-THE first off c.
ial trial of the Maine was made this
afternoon In Long Island Sound. 1t de-
monstrated to the satisfaction OF the
official board and the proprietors of the
Quintard Iron Works of this city, who
built her machinery, thai the vessels
engines. will make the 5000 collective in
dicated horse power called for in the
contract with the Navy Department and
something over. The Maine left her an
chorage off the Pequot House at the en-
trance to New London harbor, at noon.
When her anchor was at the bow, SIZE
turned in half her length and headed
out through the race, then eastward to-
ward Block Island. Her manoeuvreing
pleased Captain Bunce and the aides
exceedingly. When off Watch Hill,
southeast of Fishers Island, the helm
was put over, and turning i'll an arc OF
A great circle toward Montauk Point,
she swung round to the westward and
headed back through the race. The
wind was from the westward and fresh,
and gave promise of an increase. When
the. Race Rock light was abeam, at so,
the trial began. 1t was twenty minutes
before she was fairly under way. The
duties of the engineers and judges called
for the taking of data showing the de-
velopment Of power in the Maine's en-
gines, as recorded Sby diagrams taken
from the indicators at both ends of the
three cylinders; also on auxiliaries in
contract as we'll as steam pressure at the
boilers and at the engines the number
of revolutions per minute, the amount of
forced draft, and other factors to deter
mine the result. These observations by
the trial board were taken in periods of
ten minutes each during four hours. At
Rthe end of four hours-5. 80 p. m.-off
Stamford light, the final reading OF the
indicators was made. During the four
hours of unforced draft, the general av-
erage of steam pressure was 141 pounds
at the boiler, and not far from the de-
signed average of 1876 pounds at the cylin-
ders. The propellers were making 127
revolutions per minute on a sustained
average during the four hours, the va
cum being sapproximaty i26 inches. AS
the ship got farther up the Sound to-
wards New York, the wind increased
until clouds of spray from the bow were
at times thrown over the tiyng bridge.
The temperature at the cylinders un-
der the protective deck, in the engine
room, wes 1S0 degrees on Ean average,
and 40 degrees on the fire room. The
PIesiueHb o.. bne oiHcial Doafu CnleI
Engineer Ayres, at the close of the run
had nothing but praise for the apparent
result and the smoothness with which
everything passed off. He said the men,
bers of his corps would be busy at the
navy yard, working out the data, for
several days and full report would 90
to Chief Engineer Melville at Washing
ton about the middle of next week. AL
though the trial was for horse power, the
speed of the Maine was noted For 25
miles her, average speed as 15 SO knots
an hour, with an allowance for tide, the
result WAS II. 25 knots. The trial ended
and the ship came on to the end of the
Sound and shortly before anchored off
Whitestone. Chief Melville and other
guests, with member of the trial board,
took train for New York.
