INTERESTING COMPARISONS OF
DIFFERENT FUELS.
The Southern California Uses Petroleum
Successfully on q Big Locomo-
tive-Ths Prescott and
Ph9uix Road.

The series OF exhaustive tests being
made by the Southern California Rail-
road company with the oil burning
locomotive has proven, SO far. very
successful. The engine is q huge 10
wheeler, and the laet run up the Cajon
pass from San Bernardino was par
ticularly severe. Sometime during the
| current week the engine will be brought
to this city.
Recently some interesting experi>
mepts have been made to determine
the value of different fuels as compared
with crude petroleum, and the results,
as given in certain of the engineering
journals, have been recorded as follows:
Coke that has about "a per cent of car
bon is found to contain 1880 heat
units, requires nearly IL pounds OF air
for complete combustion, the rice in
temperature being 4S77 degrees F.,
and the maximum amount of water
that it will evaporate is 14.12
pounds for each pound of coke. A very
good grade of bituminous coal, contain
ing more than 81 per cent of carbon.
contains IA, l43 heat units, requires IL
pounds of dir for complete com mbustion,
the rise in temperature is 4S30 degrees
F., and the maximum amount of water
evaporsted nearly Is to this, how
ever, being An exceptional case. Illus
minating gas OF 81 per cent carbon con-
tains 20, 800 heat units, requiring nearly
16 pounds of air for the combustion OF
each pound OF gas, the rise in tempera-
ture is 1867 degrees, and each pound Of
it will evaporate more than 81 pounds OF
water. Oak wood, when kiln dried,
contains about 30 per cent of carbon,
has Tl3 heat units per pound of wood,
requiring six times it's own weight of air
for it's combustion, giving rise in tenn
perature OF 42S7 degrees, and each
pound OF it will evaporate eight pounds
OF water. Wet and green eawdust, con-
tanning 45 per cent of wool and 55 per
cent OF moisture, develops 29l6 heat
units, giving a rise in temperature OF
2245 degrees, and will eveporate four
pounds of water for each pound of wood
in the fuel, though for each pound as it
stands-wet and dry together-it is
much less.
SANTA FE, PRESCOTT AND PHOENIX ROAD.
Ex-Governor Murphy of Arizona.
while passing through the city, spoke
very highly OF this road connecting the
Atlantic and Pacific with the southern
portion of Arizona territory. The rail-
road grade is completed to Wickenburg,
65 miles from Phoenix, and the five
grading camps are now working in the
caiion of the Hassa-yampa. Cars are
running to Martinez and within a week
Congress switch will be the terminus.
The construction of the road mas al
ready had good effect in creating a
market for produce, and mineral dsvel-
opments are also being made that ul.
timately will mean a great deal to that
portion of the territory.
NOTES.
E. J. Swords, prominent official Of
the Chicago, Burlington and Quincy
road, arrived with members of his fam.
lip in special car No. 153. Today the Car
will be run through to San Diego, where
Mrs. Swords will remain for some time,
for the benefit of her health.
