CYCLONES.

The last forty years have done much
toward developing the usual course ana
characters Of cyclones, or rotary storms,
and TO lessen the danger by foreteiiing
their approach, in many places. Accord
ing to tho latest authorities on the gen.
eraI topics OF cyclones, person occu-
pyine position toward which one is APP
proaching, may observe a peculiar hazi-
ness In the atmosphere. q cessation OF
the usual trade winds, a lassitude in the |
air, and an ominous stiffness. Then fol-
low The slow fall of the barometer, light
breezes, increasing into high winds, and
the observation OF the sky by uniform
clouds. In the course of twenty-iour |
hours the storm has usually attained
something like its greatest severity,
though the time varies; tremendous
rainfall follows with deafening roar,
violent gusts OF wind, before which trees,
houses and other objects are Frustrated.
The highest speed ever actually marked
in hurricane, was 100 miles an hour on
the British coast In the hurricane of
1871 the U. 5. Signal officers recorded
velocity Of eighty-five miles in the wind
on the coast of Florida. These storms,
on this hemisphere. start on the equator
and move with circular motion toward
the north. being, in fact, vast whirlwinds
moving from the tropics. and varying in
width from q hundred to n thousand
miles, while there is an almost complete
calm in their centers, sometimes thirty
miles in extent, and increasing in dimen-
sions as the storm moves northward.
The barometer falls lowest at the cen
ter Of the storm. where the depression is
sometimes two or three inches. The
barometer begins to fall while the cyclone

milss distant. and falls steadily a. the
tempest approaches.
The waves produced by cyclones are
the most formidable known to navigators
They form in advance OF the approach
ing storm center. and become cross sef
by the changes in the direction OF th
wind and the ref ection OF the waves forl
the shore, and the smaller waves throw

regard to the effect of the wind.
Since the year 100 about twenty-f'

which is the section Of the United Stat
most frequented by them.
These notes refer to cyclones origina
ing on the equator. Modern observe
say that another class originate on Il

Notwithstanding all the inyestigatio
of the last forty years, much is yet
doubt in regard to the phenomena
these great storms, and their alleg
complications with the movements Of
planets and the time of the year, Th
are not wholly confined TO the Fall
Spring, but have occurred during all !
months. The connection between b
ricanes and solar spots is among
most interesting of modern investi
tions on the subject. 1t is held by ma
that when spots on the sun are most !
merous cyclones are most frequent a
severe. SIC
