gar there they sail for New York.
The fleet consists of the American
Hawaiian, Oregonian and Californian
5000 tons each; Alaskan, Texan and
Nevadan and Nebraskan. $500 tons
each. These are all good American
names. The last two steamers are de-
signed for the San Francisco Honolulu
trade exclusively They are provided
with cold storage plants for transport
ling meats to the Hawaiian islands and
| fruit from the islands to San Francisco.
| The entire fleet is completed with the
exception of the Arizonian, which will
be finished in about two months. The
Nevadan and the Nebraskan have al
ready been fitted with tanks for carry
ing fuel oil. and the other steamers will
be equipped with the apparatus as fast
as possible.
| The Nevadan has made three round
trips between San Francisco and Homo
lulu using oil as fuel, and the Nebras-
kan is now making her first trip. The
distance covered by the Nevadan In the
trips was 1880 miles. The owners are
satisfied that Oil is the best fuel for
them to use on their vessels from the
results obtained from the Nevadan.
In the system used the Oil is atonized
by air introduced at low pressure. and
air before entering the Are boxes. The
Neradan and the Nebraskan are pro-
yided with oil tanks of $50 tons ca
pacity, sufficient to take the steamers
from San Francisco to Honolulu and
back again and leave eight hundred or
nine hundred barrels in the tanks at the
end of the trip.
On the last trip of the Neyadan to
Honolulu, which was begun at San
Francisco on Oct. 9. and terminated on
Oct. 16, the experimenting engineer of
the line said recently:
expected. The boilers and engines We're
worked to their full capacity. Not a
burner was stopped turnout the trip.
The steam was kept at zoo pounds, with
no variation OF more than a pound or
two Ordinarily there was not the least
sign of smoke from the stack. The
boilers developed $500 horsepower.
Only Lag pounds of oil were used per
indicated horsepower. The consumption
was S,o0s pounds, or nine and one
fourth barrels. of oil an hour. The time
of the trip was seven days and three
was 1913 knots. Running with coal, we
would have made one knot less speed.
The advantage of oil over coal, as indi-
Gated by our experience, is that 20 per
cent more power can be obtained from
the same boilers. Not only this. but
the pressure is maintained at the same
point. There is reduction in the cost
for labor in the freroom. We save
twelve men. Instead of nine firemen we
use three, and are obliged to have no
coal passers. of whom we should re-
tluire six IL using coal.
"0n the return trip the engineer was
directed to run at a speed of ten knots
an hour as an experiment. The steam

In San Francisco on Nov. T. The speed
was 1854 knots an hour The burners
worked with the same success as on the |
outward trip. The amount of oil burned
WAS 1890 barrels, or 7.2 per hour This |
was 191 barrels less than on the out
ward trip. The horsepower developed

Ter indicated horsepower was I.27I
pounds. While the difference in the
quantity Of oil used was 1e1 barrels, it |
cost days time. Apparently it is |
more economical to use the maximum
power of the boilers and engines. We
have found that pound of oil will
eyaporate from fourteen to fifteen
pounds of water, while pound Of coal
will evaporate only from nine to nine
and quarter pounds"
Speaking of the future of oil as a |
fuel for steamships, he said that he
thought 1T was better adapted to fast |
passenger steamers than to freighters, |
and that he looked for it's development |
In that direction. 81 think" said he. t
that oil will be used in two years on
such steamers as the Deutschland, the
Lncania and the Kronprinz Wilhelm. |
Oil will give 20 per cent more power
from the same boiler plant, will reduce
the fire room force on such steamers |
from sixty to eighty firemen and forty
toal passers, will give a more even
of steam, and evaporate rs per
cent more water per pound of fuel"
1t has been found that, while the spe-
cine gravity of oil is lighter than that
or coal, ton occupying from thirty-
four and thirty-five cubic feet of space.
t slows so much better that from 15 to
20 per cent more oil than coal can be
slowed in given space.
