sixty years whose temperature records
have been dug into, have abnormal
temperatures been so everlastlngly on

Even last winter, which we remem-
Der az an extremely mild one, was the
beginning of the extended heat wave.

Chicago has, however, been the hot
spot OF the country this summer, an
nalysis of reports show. July was
he hottest month that that city has

normal. That city has been SO con
tinually hot that the average temper

Of July has been the large total Of

Europe Also Hit.
| Western Europe has also expert
enced similar continued hot weather,
according to data that have reached
here. and II has been accompanied by
lack of rain and Is causing drought In
England and France. How the rest
of the world Is affected, weather bu-
reau officials do not know, as data
from other sources have come In very
slowly and are meager.
The theory that sunspots have any
thing tn do with the hot spell is scout
ed by Prof. Charles +. Marvin, chief
of the weather bureau. Some scien-
lists In Europe and this country have
declared that there is evidently some
connection, but Professor Marvin, az
ter examining the data that have been
obtained on the intensity of the radI-
alton during the presence and absence
Of sun spots, has come to the con.
elusion that atmospheric tempera lures
are not perceptlbly affected by spots
| on the sun.
1--WE find that the temperatures and
rainfall seem TO vary with the pres
sures of the atmosphere, particularly
in the so-called 'eenters of action
which seem to be critical points for
atmospheric changes" Professor Mar
yin states. "These large air move
ments caused by pressure changes
seem to be real causes of temperature
changes apd precipitation. hut We
have yet TO learn what causes them"

been experiencing is no sure sign that
