November, December, January February
and March, which are the only months to
which these generalilations apply.

central line ofthc storm. aud rise Of ba.

8. This central line Of minimum press.
ure Is generally Of great length, from
north to south, aud moves side foremost
towards the EAST
1. This line Is sometimes nearly
straight but generally curved, and most
frequently with is convex side towards
the east.

thirtysix miles an hour.
G. When the barometer falls suddenly
in the western part Of New England, II
rises at the same time in the valley of the
I Mississippi, AMI also at st. John, New

4 T. In the great storms the wind flr
several hundred miles on both sides of the
4 line of minimum pressure blows towards
that line directly or obliquely.
! s. The force OF the wind is in proper
tion to the suddenness and greatness OF
the depression Of the barometer.
4 9. In all great and sudden dcpressions
of the barometer there is much rain OF
snow; aud in all sudden great rains OF
SHOWS there is great depression of the
barome CT near the centre of the storm

States.
IL. When storm commences in the
/ United States, the line of minimum pres.
sure does not come from the "far west,
but commences with the storm, aad tray
els with 1t toward the eastward.
l3. There is generally a lull of winc
at the line of minimum pressure, anc
sometimes a calm.
ii, When the line Of minimum pres
sure passes an observer toward tho east
the wiud generally soon changes to the
west, and the barometer begins to rise.
10. There is generally but little winC
near the line Of maximum pressure, anC
on each side of that line the winds are IL
regular, but tend outward from that line
l6. The fluctuations of the barometer
are generally greater IN the northerl
than in the southern part Of the United
States.
II. The fluctuations OF the baromete
are generally greater in the eastern thar
in the western part Of the United States

cd States, the wind, generally in grea
storms, sets IN from the north Of east ant
terminates from the north of west.
10. In the southern parts Of the Unit
cd States the wind generally sets in fron
the south of east and terminates from tn
south OF west.
20 During the passage Of storms th
wind generally changes from the east
ward 10 the westward by south, especial

states.
2l. The northern part Of the storm
generally travels more rapidly toward
the east than the southern part.
