any metal substance allowed 10 enter
the liuuad viii cause il to boil and
aside from the losses. resulting from
this operation Will render IL impos-
siblo 20 secure an accurate gauge.
ON account of the initial boiling
point usually being below atmos-
phcric temperature, any article OF
metal allowed 10 fan into the car Is
liable 10 cause the contents 20 boil
over the top and tho element of
danger attending an accident of this
kind Is readily apparent.
Sampling.
In sampliug the contents Of th'

or the container. with which tho
sample Is TO be taken, is as near thu
initial boiling point OF the gasoline

Unloading.
The practice OF unloading cars
by the use OF air pressure mas been
employed IN some instances but
should be discouraged on account
of the element Of danger Involved

very great and there is on record
one explosion resulting from thls
practice, In that case II Il reported
that the air compressor discharged
directly into the line leading 20 the
car and there were no non-return
or check valves TO prevent the gas0-
line Vapors backing up into the ar
compressor a pressure tank be
