The review. [volume] (High Point, N.C.) 1908-19??, 1918-08-08

by DR.. Charles i. Parsons, chief cn0n-
LIST, bureau OF mines department or the
interior, I'm an argument for discontinue
| ance OF the use OF platinum In jewelry.
1.-THE war cannot be won without
| platinum" says Doctor Parsons, land
it is equally essential In times of peace
IL our country is to excel Germany In
the development OF chemical science
| and industry. With the aid Of plati-
| mum from one ordinary wedding ring
about 100 pounds OF nitric acid can be
| made every "a hours. This 100 pounds
OF nitric acid converted into high ex-
| plosfves viii send number of three
inch shells against the Germans and
help to bring the boys back home.
Platinum rings, pins, cigarette
cases, and mesh bags are not factors
In winning this explosives are. |
wonder If the purchasers and wearers
Of platinum jewelry know that explo-
sives cannot be manufactured without
the use Of sulphuric and nitric acids;
that the manufacture Of these acids re-
quires the use Of supplies OF platinum;
that airplanes must have platinum for
important instruments they need; that
platinum is absolutely necessary in the
manufacture Of special promoters !;
that promoters are necessary in all
steel treatments; and that no guns can
be made without the use OF promoters.
There is a shortage In the supply Of
platinum. Russia has a corner on the
worlds supply, and Germany is in Rus
STA. Our domestic production of plati-
iS wv
requirements are increasing at a rapid
rate"
Many housewives have learned from
sad experiences in loss of perishab1e
coolest place in the home refrigerator.
To the housewife who has not had this
experience the food administration
gives this advice:
"Many put their butter and milk
right next to. the Ice because they
think this is the coolest place, but. as
a matter Of fact, the coolest place is
at the bottom Of the refrigerator. Hot
air rises and air that Is not being con-
stantly purified by circulation around
the blocks of ice soon Is unfit to
When the warm air in the refrigera-
tor rises it carries with it impurities
and moisture which are absorbed from
the surface of the food and which If
allowed to remain in the air spoil
the food. The air which is warmed by
passing over the food comes in con-
tact with the ice, where the moisture
is condensed upon the surface and the
impurities are carried Off by the melt
ing ice. The air is thus dried, cooled
and purified. The cooled air immedi-
ately descends to gather up more mois
ture and impurities and thus the
process is repeated continually.
cit is advisable to allow heated food
to cool off before placing 1t in the re-
frigerator. If put in when warm it
raises the temperature Of the refriger-
ator higher than it should go and
melts ice unnecessarily. The trapdoor
through which the meltage passes out
at the bottom of the refrigerator
should be kept in place, because If it
is broken or lost constant stream of
warm air is allowed to flow into the
refrigerator"
The war department has opened a
great storage lumber depot at Gilmer-
ton, Va, to meet emergency demands
OF the army for lumber. Through its
operation it is estimated that a yearly
saving Of approximately $250OOO will
be effected.
Whenever army constructors in the /
past were required to buy additional
lumber the purchases were made at
yards in the immediate vicinity. The
average increase in. price for this ma
terial over the lumber originally pur-
chased for the job would run from 50
to SIP per 1000 feet. By purchasing
In large quantities and charging only
for yard maintenance the greater part
Of this excess price is expected to be
saved to the government.
A stock Of from twelve to fifteen
million feet of lumber will be carried,
and it is estimated that the yearly
turnover will amount to between fifty
and sixty million feet. A fund of
100000 has been set aside by the war
department for use by the construc-
ton division of the army as necessary
working capital for the yard.
The supply Of kerosene will run
short next winter and the government
is urging every user to do his part
toward making every gallon to do full
war duty by giving forth its full
measure Of light and heat. Saving can
be accomplished, it is said, only If
care is given lamps, lanterns, heaters
and stoves.
The director of oil conservation Of
the United States fuel administration
issues these rules for fuel-oil saving:
Keep all lamps and lanterns clean.
Let the light out; don't conf1ne it be- |
hind smoked and dirty chimneys.
See that burners and wicks Of all |
oi1-burning devices are clean Clean |
burners require less OIL and give bet
