TALKS ON TEMPERATURE.
Possibilities of August Weather, as
Shown by the Records.
Death Valley, East of the Sierra Ne
vadas, the Hottest and Dryest
Spot on the Continent.

The monthly bulletin of the California
Weather Service, in cooperation with the
State Agricultural Society for June, COM
piled by the Director, James A. Barwick,
has been issued. The data is derived
from 81 points of observations, go of
these being reports from the Southern
Pacific Company's different meteorologi-
cal stations in the Pacific Division.
One new feature noticed, is that the Di-
rector has added to his bulletin the COM
parative or average weather for the COM
Ing month Of August, as deduced from
records Of from five to twenty-one years,
it being q years at San Francisco, Is
years at Red Bluff, Sacramento and Los
Angeles, 20 years at San Diego, Is years
at Yuma and years at Keller.
We find in that comparative data that
the highest temperature in California,
north of the Tehachapi range of mount
aims and west Of the Sierra Nevadas, oc-
Cured on the I'D day of August, 1891,
when it was 1862 in Sacramento, 92o in
San Francisco, TO in Eureka and 1l4o in
Red Bluff, while Keeler's hottest August
day in seven years was 1882 on the 10th of
August, 1856; Los Angeles, 1869 on the
the 10Th OF August, 1884, and Yuma,
Ariz., ll5', on the 9TH and 10Th of August
1879.
The above data show the uniformity
OF hot waves in Northern and Central
California-thaU they cover the entire
portion of that part OF the State, and
eliminate in the greatest thermome-
trical record on exactly the same date
and year for very great expanse of
country. Southern California does not
coincide in her records of high tempera-
lures on the same date and the same
year. For instance, Los Angeles re-
corded its hottest day in 1885, Keeler in
1856, San Diego in 1884 and Yuma in
1879.
The selected notes on the climate of
Death Valley, in Inyo County, are well
worth reading. The article reveals the
fact that every day in July and August
the temperature reaches above 1902. The
highest in June was 1920, there being
only two days when the temperature was
below 1902, but in July and August, 1891.
| there were no days when the highest
temperature fell lower than 1922, the
average highest being Il6' for July and
10 for August, and the highest, 1929 in
both months. Itappears to be the dryest
and the most continuous hot country yet
discovered.
