OMAHA. NEB. Aug. 30.-As stated in
my last letter secondary weather DIS
iurbance will be due in the Mississippi val
ley not far from September It. After that
the next regular storm wave will be due
to leave the Pacific coast about the I'd,
cross the Mississippi valley from 81 Il
9th, and reach the Atlantic about the
9th. About that time the period OF
heavy rains, shat occurs about every
fiity-two days, will be due, and for the
next two weeks, 9th TO goth. we may ex-
pect general increase in the rainfall.
1t is often important to know what day
iu the week Will probably give US the
best weather for out door work. l ex
pert the clear weather wave to leave the
Pacific coast about the 4th, cross the Mis-
sissippi valley about the 9TH and reach
the Atlantic about the 9Th, and these
dates will probably be the best for out
door work
As the atmosphere rises in the center
of the wnirlwind and the storm Its pres
sure Is less 1t. the atmosphere, rising,
does not weigh so much and therefore its
lighter pressure Is called low barome-
ter. and the latter phrase is Synonymous
10 storm center. But GLOW barometer
is IL misnomrr. ii was formerly sup
posed that the atmosphere moved in
waves like oceun waves, ana that under
the waves the atmosphere would weigh
more, and tbeV called that high Da-
romtter because they supposed that the
tide WIS high there in the atmosphere,
aud where the atmosphere was light and
caused low barometer they supposed
there existed a low tide or depression in
tine atmosphere. But that Is oil IL mis-
tnke. and the very reverse is true. The
atmosphere is deeper over the low bu-
rometer where their whirling or
spiral motion, as do the mir and
clouds in the storm. These whirlwinds
and the storms have forward motion.
Renders of these forecasts will have
recognized the success OF my forecasts as
TO the recent Tomatoes, 18Th and ooh.
| gave the dates of that storm wave as
10th 10 18th for crossing the Mississippi
valley. the 10Th for the greatest force of
the storm in the Eastern states, and Goth
for the time it would reach the Atlantic.
The forecast was completely verified
The storm was destructive in the Missis-
sippi valley, very destructive in the
Eastern states. September will also
hAvd very dangerous tornado period.
dates of which | will give in my next
letter.
In my last letter l was discussing the
nature of storms and had illustrated this
by the whirlwinds. We see that oil
whirlwinds and storms whirl IN the OPP
posite direction from the movements of
the watch hands; that dust, Leaves and
the air move towards the center of the
whirlwiud and rise, besides the air is
lighter from the very simple reason that
the air rises aud shoots far upward, AMI
from the top of that ridge it floats off:
descending again toward the earth till il
reaches the high barometer vortex,
where il Dours down toward the earth
like great waterfall, except that ii
comes down in u cir, le or spiral. When
il reaches the earth it ngnin moves to-
ward the low baro eter aud there again
rises, and thus it keeps up this perpetual
round. The air Is caused thus to move
by an electric current which will lie eX-
