IF the upper current of clouds comes
from the northwest in the morning, a
fine day viii ensue.
II clouds float at different heights
and rates, but generally in opposite di-
reetions, expect heavy rains.
When you observe greenish- tinted
masses of composite cloud collect in the
southeast and remain there for several
hours, expect a succession Of heavy
rains and gales.
When 1T is evening, we say it will be
fair weather, for the sky Is red; and
IN the morning, it will be foul weather
today, for the sky is red and lowering"
Matthew xvi, 2, g.
The best guide we now have for de-
terminating future weather conditions"
declares Professor Garriott 'is the In
olcations furnished by the barometer"
That is, "a falling barometer, as rule,
indicates rain. or snow or wind; a ris-
ing barometer, fair weather or the ap-
proach of fair weather"
The reasons of these indications are
partly explained. To translate the sci
ence of Prof CARROTS bulletin, a low
barometer means that the atmosphere
is at that time comparatively light and
does not press the mercury upward in
the barometrical tube; a high barom-
eter means that the atmosphere is
heavy and does press the mercury up
ward. But an area of light pressure
or low barometer in the air may be
compared with whirlpool in the sea,
or, more Familiarity, to the eddy in a
WashpoWl when the water is allowed to
escape. The air currents, that is, the
winds, flow out, are squeezed out so to
speak, from the area of high pressure
and take the shape Of great spirals as
they HoW into the area of low pressure.
These spirals, assuming a circular or
oval form, proceed always in the direc-
ton contrary to that taken by the
hands Of clock. And so if ST. Paul
was Tow" to-wit, center Of low
pressure, winds would be blowing into
the neighborhood of st. Paul from all
directions; winds from the eastward
would point toward the north; westerly
winds would point toward the south.
Moreover, Minnesota weather comes
always, or nearly always, from the
northwest; the low pressure areas
moving in a general way from the
northwest to the southeast Thus when
the low is west of ST. Paul the winds
may be blowing here from the east or
southeast, yet at the same time the
weather" itself, that is, the low pres
sure and the highs" near it, may be
going eastward. After the Glow" has
passed here the wind agrees once more
with the weather currents and blows
from the west.
Bulletin No. 80, at this point, heaves
long, proud sigh; it has been ex-
planning matters so profoundly in Ian
guage much larger than that Of the
foregoing paragraphs. ~
1.-The wind directions thus produced. -
resumes the Bulletin, splitting particles
like a layer or a scientist, "give rise
to, and are responsible for, an local
weather signs. The south winds bring
warmth; the north winds, cold; the
east winds, at least in middle ATTITUDES,
indicate the approach from the west
ward Of a low barometer, or storm
area; and the west winds show that the
storm area has passed to the eastward
which is precisely the doctrine of
Izaak the Fisherman.
The following dicta are therefore set
forth with which to line ones head
gear.
Rapid changes in the barometer in
dictate early and marked changes in
the weather.
"a sudden rise in the barometer is
very nearly as dangerous as a sudden
fall, because it shows that the level is
unsteady. In an ordinary gale the wind
often blows the hardest when the ba-
rometer is just beginning to rise, d.
rectly after having been very low.
TN summer, when the barometer
falls suddenly, expect a thunderstorm
and if the mercury does not rise again
when the storm ceases. there will be
several days of unsettled weather.
"A summer thunderstorm which does
not much depress the barometer will be
very local and of slight consequence.
when the barometer falls consid-
erably without any particular change
of weather, you may be certain that a
violent storm is raging at a distance"
