Is This Propaganda Against
Tariff on Mexican Oil
(From New York Horald)


Jugt out OF the hands OF an over
hauling crew and equipped with ad-
ditional oil bunkers, the white Star
liner Olympic, largest British steam
er now In commission, sailed back To
Europe last week with the record TO
her credit of having required only
two days for the turn around in this
port For n vessel of 46,439 tons
register TO have fuelled, replenished
her supplies and taken on cargo and
passengers all in two days was "A
remarkable feat. II was vindica-
tion of the belief that for ships like
the olympic and the Aquitania oil
IN the best fuel. a theory which was
not universally accepted by ship
ping authorities even as late as "A
year ago.
But IL the experience OF the last
year has proved the wisdom of con-
verting the larger passenger steam
ers into oil burners IL also has shown
that oil MS fuel for other classes OF
ships has its limitations. Burned
under steam burners, as Il is in the
case of the Olympic and the Aqui-
tania, oil yields only part OF Its
maximum power producing eff
cheney. No matter how perfect may
he the combustion under the boilers,
a large number OF heat units so up
the stack. The economic waste thus
resulting can be justified only where
speed on voyage and in turning the
vessel around in port Is the first
consideration.
Ships like the Olympic and the
Auuitanla carry little cargo. They
are built TO provide rapid passenger
service, to expedite the mails and
to act as show horses. The vast
amount Of capital tied up In these
ships makes 1t imperative that they
lose no time in port. And each day
clipped from the length OF the voy-
age Is like giving back that much
matter OF a day less in port or Of
half day less on the voyage would
in q few years amortize the cost of
the vessel.
In her former coal burning days
Il would not have been possible for
the olympic to turn around for the
outward voyage In two days. Her
coal bunlSers held 1871 tons and It
look four days to fiji them. And this
coal was only enough for the trip
one way. when she was converted
to an oil burner her tank capacity
was fixed at 5,06s tons. II was
found that 5000 tons We're required
for the round trip. She now comes
out with an oil bunking capacity of
1855 tons and she will In future
be able in six hours to fuel for the
round trip
For the advantage OF saving n day
or so in port the owners OF the giant
passenger steamers can afford to
waste some oil But II all the ships
of the world were to consume oil
without thought of anything but
speed IL would not be long before
tho petroleum supplies would he eS-
hansted.
The internal combustion engine
gets the maximum power from oil
but this type OF propulsion is not
suited TO all ships. especially the
slow going freighters, which must
remain in port several DAYS loading
and unloading and which call at
ports where oil fuel cannot be OBJ
tanned.
OIL for fuel has won the day In
| the particular case OF the Olympic
Rut for every such speed queen OF
the deep there are hundreds OF les
ser ships of the plebean class still
nosing in and out Of all the ports or
the world, running on coal
