Planetary meteorology Is coming t
be recognized by scientists. Prof. Je
rome s. Picard, the astronomer of Sar
ia Clara college, Santa Clara, Cal
has long believed that sun spots hav
ans important relation to our weathe
changes. He has proven definite re
lation to our weather changes. H
has proven definite relation betwee
the dates on which sunspots reach th
western limb of the sun and the date
on which the highs and lows reac
the Pacific coast and by his dali
telescope observations Is able to fore
cast the arrival of storm waves on tn
Pacific coast. AS the weather burea
has great difficulty in forecasting tn
approach Of weather changes tina
come from the Pacific, Prof. Ricard
Isunspot discoveries are of very cor
siderable Importance.
Prof Ricard Is also a believer
planetary meteorology and in recer
letter to me says: ri have put you
forecast to the severest test | al
capable of by watching day after da
and week after week the entrance {

slope-or to use the language of th
weather map, the appearance Of tn
new lows and the new highs on th
