Il the key to all weather changes
The country over which the storm
wave passes, centrally, will have
very cnanseable weather. The
center Of the storm wave produces
warm. clear weather. All around
the center is a cloud belt from which
may be expected snow or rain.
All around outside Of this
cloud belt ia the very cleaIest Of
clear weather. South and east Of
the stora wave the weather viii be
comDarativeiy warm; north anu
west OF it cool. The south half Of Il
win cause rain and in winter the
north half snow. With these facts
well in mind one may know the
kind OF weather to expect by know
ing when to expect a storm wave
and about what route Ii will take. If
the cen er OF q storm passes your
I locality, first viii come the very
clear weather and the heavy frosts;

weather grows warmer, the cloud

/ clouds break away anu many are
led ~ believe that the storm i over,
but the cloud belt will follow the
clear centre and often the worsl
part Of the storm. Following this
comes the very clear belt again with
cooler weather and wind from the
north or northwest

The astronomers have recently
made an Important discovery IL

was formerly supposed that Mercury
rerolved 90 its axis IL about -
hours which conclusion was reacheh
from Observing spot On the planet
which each day appeared nearly in
the same place, thereby leading the
astronomers to believe that in the
interval the planet hai maize a revo-
luton GU lis axis. The error was
difficult % detect because the planet
can bc favOTably d served Only about
one hour eacn day after sunset OF
before sunrise. The planet Is 50
near the sun that the brightness Of
the latter iuterirres with observation
out one Of the European astrun-
OmeTs has made it a speciality for
several years 10 investigate this
planet and with fine telescope he
has made daylight observations aud
now announces that Mercury keeps
the same side 10 the sun as our moon
does to the earth all the time. This
would cause perpetual day on one
side Of Mercury. and perpetual night
on the other This condition would
prevent that planet from haviugany
equinOctial influence on the sun anu
other planets because it Ievolves too
slowly, making q revolution on its
axis only once in IS days. This is
in exact accord with my caleula-
tons for do net include any equi-
nOxial influence for Mercury aud
only ascribe 10 IL great disturbing
influence when it cruises the sun's
equator at2Sl and I minor influence
when IL crosses the suns equator at
81. The moons influence is very
similar. The greatest cause Of
weather changes Is the moon cross
