other important constituent Of air. was
successfully liquified several years
later. It was at this time that Prof.
Dewar Of England produced some
quantity Of not only liquid oxygen, but
liquid air. at cost of about So, 900 an
ounce. Since the success of this ex-
pertinent scientists believe that every
substance can be reduced to any Of the
three conditions. By heat it may be
vaporized, by extreme cold, even the
most refractory gas be reduced to
sparkling liquid or snowy solid. These
experiments attracted the attention of
Mr.. @. E. Tripler, a civil engineer of
New York, who worked earnestly for
eight years with the result that now
the liquid which was produced at such
great expense is made by the barrel at
a cost Of about 20 cents a gallon.
When extreme cold and pressure are ap-
piled to the air we breathe liquid
with slight BLUSH tinge is obtained
This liquid is not wet to the touch but
causes severe cold, being about 312 de-
lately that compressed air was used
instead of gasoline or electricity for
motive power, but this is likely to be
superseded by the use Of liquid air, the
motive power Of which is it's most i'm
portant factor. Mr.. Tripler has sue
ceedsd in running a small engine in his
laboratory with liquid air and thinks
that if small engines may be made to
run, why not large ones, and he is ell.

may be used in practical machinery.
It is thought that because Of the small
amount Of space occupied by liquid air
it will be applied in aerial navigation. -
She said that in many cases metals
could be frozen by the use of liquid air
and that fruit, butter and eggs may be
frozen so hard that they may be re-
duced to fine. dry powder. 1T is
impracticable to keep this liquid
count Of it's tendency to evaporate. =
She said, ''The discovery Of liquid air
suggests an explanation for the fact
that the moon is without atmosphere.
The heat was radiated from the moon
till the air, becoming cooled below 312
degrees below zero was probably pre-
cipitated as moisture, and as the cold
increased crystalized. 1t is not at all
improbable that millions Of years hence
this will occur to the earth as it is
rapidly radiating it's heat. So many
new discoveries are made in science
nowadays that people are ready to be-
lieve almost any statement that is en-
dorsed by scholarly name; but, while
the name of Mr.. T1ipler has been be-
fore the country for SO short a time, it
promises to remain permanently as
sociated with the greatest scientific
wonder of the closing century,
progress" by Miss Prudence Miller
Miss Prudence Miller's subject was
Progress. She spoke Of the ad-
vancement of the United States in all
the different lines of work. She said in
part:
''The close Of each day finds us either
advancing or retrograding, we are
never standing still; when the sun sets
we are not where we were at it's rising,
we have progressed or we have re-
treated; every action advances or re-
tards our growth; every organ OF our
body, when unused, loses its function
every time we fail to use our power it
becomes weaker; every time we fail to
embrace an opportunity for doing good
we lose the desire for SO doing. Pro-
gress must be mads in the mental
world-mind unless cultivated becomes
stagnant. So a nation must advance
or it will retrograde, it is an impossi-
bility for it to remain stationary
She took Spain as an example of retro
gression and told how Spain had at one
time been mistress of the sea and her
