In the fourth meteorolopica, D.
Professor ]. p. Epsy, of Wash;n
c., We find the following instruc,;,.
Civilizations:

the moderate rains and SHOWS t,s sua

States, during the months Of ~ w
December, January, February ana 'sa
which are the only months to vh Phil y 3
organizations apply.
2. The storms are ACCOMPANIES
depression of the barometer near
trail line of the storm, and a r;.a y
barometer in the front and rear
3. This central line of minimnr
sure is generally of great lenU.I 1,
north to south, and moves side g..
toward the east.
4. This line is sometimes near,v a.
but generally curved, and most i,s,a
with its curvex side toward the ~
8. The velocity Of this line il g,ss J.

necticut River in twenty-four hons
from the Connecticut to st. John n
foundland, in nearly the same ., y
thirty-six miles an hour.
6. When the barometer falls ma.
in the western part Of New Enol.rs
rises at the same time in the valley II !
Mississippi, and also at st. Jch1, NJ
foundland. y
z. In great storms the wind for 90,
hundred miles on both sides of tbeI,J
minimum pressure blows toward ths
directly or obliquely.
8. The force OF the wind is in NM
ton to the suddenness and grestrs1
the depression Of the bar meter
8. In all great and sudden depre,si,,
the barometer there is much rain orr.'
and in all sudden great rains Or snosSJ
is a great depression of the baron.
near the center of the storm, and ~ }
yond its borders.
10. Many storms are of great a.,
known length from north TO south h
ing beyond our observers on the On
Mexico and on the northern lakes +
their east and west diameter is CON-
lively small. The storms Therefore

II. Most storms commence in as

ers, but some commence in the
States.
10. When q storm commences
United States, the line of mining
ure does not come from the fai
but commences with the storm, and
with it toward the eastward.
-. There is generally lull Of wi

times q calm.
IA. When this line of minimizing

on each side of that line the winds "a

16. The fluctuations of the banu1
are generally greater in the northern
in the southern parts of the United 81
II. The fluctuations of the baron
are generally greater in the eastern
in the western parts Of the Unirea 81
10. In the northern parts Of the I'd
States, the wind, generally in great sn
sets in from the north Of east and ID
mates from the north Of west.
10. In the southern parts OF the u
States, the wind generally sets in front
south of east and terminates from
south of west.
20. During the passage Of stom'
wind generally changes rom the aslv1
to The westward by the south esps4
in the southern parts of the UnitedM
81. The northern part Of the storm
orally travels more rapidly toVGd
east than the southern part.

clear and mild in temperature, esp
if very cold weather preceded.

Some of the storms, 1t is true, AMI
