out to sea before cxhausting themselves
The center of a tornado is the focus Of
its terrific force and a track of deatl
aud destruction, while ships float safely
in the midst of a cyclone. The two
storms are Numerically opposed,
though commonly spoken OF as similar. u

''Are the storms then which Law waste

IS far West as the Mississippi The
cyclone is a production of the West In
dies. and is unknown during the sum-
mer months. During September and
October the heated tropical currents
develop vast rotary storms from 500 to
$500 miles in diameter. which sweep
in q parabolic curve against the South
Atlantic coast. The cool trade winds
blowing down the coast defect their
course and send them sweeping inland.
Passing northward they describe their
curving fight as far as Nova Scotia and
New Brunswick. and then rush with
bowling force across the Newfoundland
Banks. Some of them reach England
and ireland. The same storm ravages
the coast of Japan. and is called ty-
phOon. The tremendous breadth of
cyclones seldom gives local evidence of
their circular sweep. Their calm GEN.
tiers are much dreaded by navigators.
The Signal Service cautions mariners
against sailing into o cyclone center.
The atmosphere is always striving to
retain its equilibrium, and SO long as
some parts of the earth get warmer
than others storms will rage"
