Might Tell Weather on Sun.

Prof. George Z. Hale, a California
member of the academy, reported that
with suitable instruments an astrono-
mer can tell the kind of weather
which prevails on the sun. The at
mosphere, if a mighty ocean of eX-
ploding hydrogen can be so denoml-
mated, DR.. Hale said could be gauged
and the velocity of the storms which
often disturb the surface of the great
1uminary could be accurately meas
ured.
Dr. Hale intimated that by discov-
ering the kind of weather prevailing
in the sun it may be possible to more
accurately predict the character OF
weather that earth will enjoy.
After discussing the far off heav-
emily bodies, the scientists paid atten-
1ion to the flora and fauna of earth.

Geological examination prior to jan
