What the photographers Say About
Cyclones and Their Movem ents.
The United States naval photographer
has just issued q chart, giving tracks of a
number of the most memorable cyclones
that have visited the gulf and Atlantic
coasts of the United States since the mod

into use. Reports II sucn storms are o0.

tade and Longitude at sea vhe taeJ were
encountered Reports are als1 recei we'd
from the various shore stations, and in this
way it has been maze possible TO chart tue
acks Of number Of hurric mes.
The following observa ions are deduced
by the photographed from the mass OF id
furmaTon at hand. 1t is found that although
hurricanes may be com ne ICED during any
moath Of the year, yet there is such a
marke !. crease In their humber and vio-
lence during July, August, September and
October, that these four months constitute
what is called the hurricane season. These
months, after considering the statistics tur-
nlshsd by Spanish, Engli-h and other navi-
gators in the America seas for go years,
rank in relative danger as I llows: August
is the worst, September next, October third
and July fou tn.
The following memoranda are worth at
ten ion:
Hurricane Regions-The tropics north
of TIE tenth parallel, the Caribbean sea,
e IF of Mexico AMI broal belt curving
north estward fro about st. Thomas, and
following the Gul stream toward the Grand
Ks of New FJu dlaId.
Earliest Indications Unusually high

cirrus clouds, radlating from point on the
horizon where wlitish arc indicates tue
be ring of h center.
UHmiStakG6te SigBs-As the cirrus veil
spreads over cal, with ha os about the sun
and moon, the barometer begins to fall,
slowly bat sta lily, id the ocean swell ia
creases. The air becomes heavy, hoE and
moist. Dark red and violet tintS seen
at dawn and twilight. The heav cloud bank
OF the hurricane soon appears On the hori-
ION, like distant mountain range. Tne IA
rometer falls more rap dly and the wind
freshens,, with occasional squalls OF fine,
misty rain.
Gene al Size and Velocity of Progress
Sion.-The storm area is smaller in the
{ o,ics tuau farther north, the cloud ring
averaging alb ut 800 miles ia diameter and
the regol If the stormy winds 30) m les, or
even less. In low lati udes the entire storm

more slowly as it recurves; and finally
norUte lstward with a velOcl.y of transa-
ton of TIVE lty or even thirty miles an hour,
its area increasing RAPIDLY as it follows the
Gulf stream toward tn Grand B inks and
sweeps across the Atlantic toward northern
Europe.
TIE following laws of movement have
been annouGceI by Raw. Fs her vi es, tn q

at Havana:
"Recwesn the tent and fifteenth paral-
lels hur icane moves almost due west. In
June "a id Oct)ber) its C urse changes rap
idly to northwest and north, recurring
about the tweltetl OF tw.nt third D lral-
lei. In July land Septsmber), however, it
continues on its rtn est C urse until it
reaches lati lie 27' or % nort1, and in
August latitude 30 or 81 north, before re-
curving."
BY far the greatest number of cyclones
recurve and pass up tue g III stream before
taey fairly enter the G IL Of Mexico. Hav-
i & once got to the westward OF CUBA they
are certain to be ftl6 somewhere Ia toe Gulf
or on its coasts.
