FORECASTER McADlE HEARS
THE MELODY OF FOG HORNS
Sees the Small Mercury in the Glass Tube Crawl Down at
the Rate Of Degree Minute, and Feels the Sea Winds
Blow Over City, Dspelling Hottest Wave on Record

Professor ,-McAdie rested easy lasl
evening. He left his lofty perch on
the Mills building when he saw the
Thermometers showing twenty-five de-
grees cooler than the, preceding day,
and a nice breeze blowing from the
OCEAN at about twenty -eight miles an
hour, and went to his home, out Clay
street, near Broderick. He had seen
the small mercury in. the glass tube
crawl down at a steady pace from
eighty-one at 9 a. m. to seventy-six,
and he felt in a measure vindicated, as
California was getting back TO the nor
NAL.
Another feature of the cooler wave
that is coming over the coast is the
fog horns. They are blowing out be-
yond the heads and Mr.. McAdie- in
his Clay-street home hears their ex-
qtisite melody and he knows that the
white fleece will temper the city and
harbor. ending the sun-stroke danger
period.
II can hear the foghorns;Y. said Fore.
caster Meade last night; cant you?
1t is music, isn't q, The fog was lit
tie slow getting along the coast-slower
than l anticipated, but it is here and
my warning to our cityful Of visitors
to be ready for a quick change holds
good. We have, seen the temperature
drop fifty-three degrees in a day here
in California, and we thought nothing
of it.. At 8 this morning the wind from
the ocean blew twenty-four miles an
hour, and latersit increased to thirty
miles. The temperature dropped stead
lily twenty-five deg0es and. is about
twenty eight degrees lower now. 4
This unusual hot spell is due to one
of two causes. The first is the area
of high pressure, which brings about
a strong air movement in the lower
levels, from the mountains to- the sea.
1t is a condition very similar to the
'foehn,' or north wind, in certain locali-
ties in Germany and noted by the Ger
man forecasters.s The air is warm, prob
ably dynamically. This is the usual
cause.
1.-The otheracausef.is an area of low
barometer over Mexico and Lower Cal
ifornia. And this, / think, was the
cause this time. 1t was an unusual hot
period. intense and prolonged, and the
hottest wave on record. There will be
a falling temperature over the State
now.
with the forty five-mile wind blow
ing at Point Reyes this morning I
knew it would get cooler. There was
fog out at sea as the strong land
currents kept 1T from coming in to the
shore. Now the wind has changed
back to west and has brought the fog
to us. 1t may get quite cool, as it was
last week, and the strangers here will
see another class of San Francisco
weather. However. they may as well
be prepared for it.
Let me quote these two paragraphs
from The Call of Thursday:
All who read the weather forecasts yester-
day morning rejoiced over these words: Fair
Wednesday; cooler; light north wind chang
ing to brisk westerly, with fog.
The prophecy bore Mr.. McAdie's signature,
but there was no wind, there was no fog, and
there never has been hot a day in San
Francisco Furthermore there not so
much heat in Manila or Honolulu. in Boston or
New York. as in this city yesterday.
What appears in this clipping is
essentially correct except in the mat
ter of wind. There was wind day be-
fore yesterday, light wind from 9
O'Clock a. m. September to o'clock
a. m. September s. There were Ill
miles of wind, for which we are fully
grateful; OF ought to be.
May the time never come when we
will be without wind in this dear city,
not too much, but just enough"
