Facts About storms.


The establishment of the Signal
Servlce Bureau by Congress has
proved a most valuable un crtakiny.
\ vast store of practical Information
WITH reference ~ atmospheric condi-
tons, the causes and premonitory in
IiicatlsnS OF changes Of weather. has
been gathered. We confidently ex-
pect that before long the foundation
Of II true science Of storms will he Sc
curclv laid.
The following very interesting
are among the conclusions
'i the Bureau from carefully noted Oh
'ervations:
Storms are accompanied with de.
ressIOn Of the barometer near the
eutral line of The storm, and rise

In central line ofminimum pressure
Is g0eral!y of great length North to
Sout and moves siie-foremost to ~
sea.
This line is sometimes nearly
straight, but generally curved, ana
most freqently with It's convex SIDE
toward th,East.
The veloity Of this line is such that
i, travels froN the Mississippi to the
Connccticut Hker in about twenty
four hours, and Eom the Connecticut.
to St. Johns, Newfoundland, in near
" the same time, Or about thlrty-slx
miles an hour.
When the barometer falls suddenly
in the Western par! Of New England,
it rises at the same time in the valley
Of lbe Mississippi, and also at ST.
Johns. Newfoundland.
/ In great storms the wind for sever
al hundred miles on both sides OF the
line of minimum pressure blows 10

The force of the wind is in proper
tion to the suddenness and greatness
of the depression of the baronetrr:
