SENSIBLE
TEMPERATURE.
A New Departure in the
Weather Bureau Of the
United States.
BODILY HEAT WILL Be TOLO.
No Longer Necessary to Feel
Warm Fecause the Dry Their
mometer Scores High.
SIMPLE ENOUGH TO UNDERSTAND
Chief Moore Explained the New
Method to an Evening World'
Reporter This Morning.

Willis L. Moore, Chief of the Cnitsd
States Weather Bureau, dropped IN on
Farmer Dunn for a few minutes this .
morning.
He stopped long enough to take
look from the top of the weather
prophets tower. compliment Mr.. Dunn
on the admirable manner in which he
conducts the local bureau. and tell an
Evening World" reporter some things
which will bring JOY to the hearts Of the
people.
Then he left town for Philadelphia
and Baltimore The good news which
Chief Moore wishes disseminated Is
summed up in the statement that very
soon the Weather Bureaus daily charts
will show, in addition to the air tenn
perature. the sensible temperature. The
full Importance of this statement was
explained by Chief Moore as follows:
This new departure is for the benefit
of those people who can never reconcile
their bodily temperature with the state
ments of the degrees of heat and cold
sent out by the Weather Department.
"The average man VIII read that the
thermometer registers 30 degrees, ana
will work himself up to a correspond
aheness. because he thinks something
is wrong If he don't feel miserable with
the mercury at that point
Now, what wa have been oolng for
years s to report only the air tempera-
ture. This daily statement has been or
use only to Boards of Trade and SINH
lar bodies as showing the influence the
temperature may have on plant life.
yI>l.u tiO', Inn al
feels is very different.
1--WE call this the sensible tempefa-
ture Hereafter when a man looks at
his dry bulb thermometer and hnds shc
air temperature 95 degrees. lie need only
turn to his Vet bulb thermometer to f1nd
that the sensible temperature may DO
only So, and he can be last that warm
without letting his imagination help to
make him mere miserable.
'The sensible temperature takes IN
the humidity. and of course, there -
the other side of the question. People
who will! complain that they were never
so warm before in their lives. may fnd
that it is actually cooler by several de-
grees than it was the day before.
ITO illustrate, I'll tell you something
which will be hard to credit. Out West
at some of our RCNAv Morntai'. "fa-

for animal life will be only q, or diff

{ ordinary Thermometer reads and what
man and beast actually reels.

Use wst-bulb thermometers. They can

an ordinary dry-bu.b instrument Just

end covers the mercury bulb and place
the outer end in a cup of water. The

.'In other words the thermometer then
takes the place of perspiring animal

does"
Mr.. Moore said the United States Is
the first Government to adopt the sensi-
BILE temperature reports. Tney Will be.
he SAYS OF great use to medical prac-
ttioners who may now know just what
influence he may expect the temperature
to have on patient.
Chief Moore met a scientific body at
Springfield on Friday night, and toio
| them what strides had been made In
weather science He will return to
Washington after he has inspected the
stations in Philadelphia and Baltimore.
