Figures and Facts.
Interesting Information Con-
cerning Phoenix Climate.
A Scientific Prophecy Proclaims
Phoenix the Great Capital of
the Whole Southwest.

Capt. Giassford, of the signal service
department US. A., who was here with
General A. D. McCook a month ago,
has an interesting interview on the
climate of Arizona in late issue of the
Denver Times. The interview should
be sent broadcast throughout the Unit
ed States for the purpose of removing
an erroneous but general impression.
Speaking of stories of Arizona heat
Captain Glassford says 'These stories
about the killing heat in Arizona have
done the country great harm and when
placed beside the meteorological data
collected are about as reliable as the
jokes OF the Arizona Kicker. The facts
developed from the recorded data and
confirmed by experience show the Ari-
zona climate to be comparable with the
shoreline of the Gull states.
On the subject of Arizona eummers
he says: Now let us turn to few
facts. Phoenix is on the line of 11S
degrees extreme maximum tempera-
ture, that being the highest ever OBJ
served here. But there are in all tenn
perature records two elements, the
sensible temperature, that which ex-
presses the heat or cold felt by the
human being, and the apparent tenn
perature, mere record of how the
mechanical Thermometer is affected.
1t is only the apparent temperature,
however, that is published greatly to
the undue advantage 81 the east and
the detriment of the west"
The captain mentioned several
southern and eastern cities in which
when the apparent temperature is loo
the heat is unbearable, while the same
apparent temperature at Phoenix is at
tended with little discomfort or none al
all. He then proceeds to an explana
tion of the difference between the sen
sible and apparent temperature in the
localities mentioned and accounts for il
by the lack of humidity in the south
west. This, of course, is understood ir
Arizona, but is not so we'll understood
outside the arid region. Then follows
a description of scientific method O
showing the difference by thermom
eter between sensible and apparen
temperature.
Continuing on this subject he says
"The difference between apparent ant
sensible heat in this vicinity, beinf
many degrees. explains the summe
comfort while summer prostration i!
the east is explained by the sligh
range of difference. The very highes
official record of heat is l16 degrees a
Yuma, but the sensible heat at tn
time, that is the reading of the we
bulb was 80 degrees lower, S6 degrees
But in the eastern states 66 degrees 0
sensible heat is not uncommon whel
the thermometer stands as high as 90
~ want particularly to illustrate this
especially for summer. Considering
the apparent record the same meal
temperature for July as that at Pneni,
is not found elsewhere in the Unitet
States. but turning to the isotherm O
| places having the same sensible tenn
perature as Phoenix in July, we fnt
ourselves shifted to the vicinity O
Shreveport, Mobile, Savannah an,
| Charleston.
"To further impress these facts
have taken for Phoenix and the entir
country the July apparent and sensibl
temperatures at p. NJ, which is abou
the warmest part of the day. Thes,
temperatures are not for a single da,
but the mean for the whole month O
July for several years. These give tn
July mean for Phoenix as 100 degree
apparent temperature, the sensible
temperature 74.4 degrees, an average
difference of Is degrees. Now drawin,
the isotherms for these apparent ant
sensible temperatures for the entir,
country each through Phoenix it is fount
that it belongs on the same climati,
line that passes through the heatee
places of the tropic, while as an aetna
fact it enjoys the climate of San An
tonic. Tex, Fort Smith, Ark, Mem
phis, Tenn, Augusta, Ga., Meridian
Miss, Montgomery, Ala. and Whining
ton, N. c."
The discouraging effect of the pecu
liar and excellent climate of Pheni1
upon all sorts of disease germs is de
cribed.
The interview is closed as follows:
"These facts are deduced from dats
and supported in theory by the highes
official authority. The reason that ths
facts have not long ago been fully se
forth is that few of sound and oficia
standing ever get to Arizona. You
yourselves scarcely appreciate that a
the head of navigation of the California
gulf and near the mouth of the Colorado
river you have all the climatic condi
