morning, we may admit that the change
through east could have taken place without
being recorded. So far, then, it seems that
we are able to show that the cyclone centre
was south of Barbados on the 18th and had
advanced to that position from the east
ward on the previous day. The in
iuence of the cyclone was continued
on the 18th, when we have southeast
winds both morning and afternoon, but by
the 18th it had completely passed away, for
we find ordinary trade wind directions pre-
Vailing on that and the two following days.
Turning to Dominica we find great irregu-
larity, and we should have left the island out
of the list, but for the fact that it falls into
line with two entries of Sc. wind on the
18th. The truth is that the mountains so
greatly modify the air movements around
ROseau that those movements cannot be
trusted TO represent the general movement,
for the local influences are too strong.
Passing on to st. Kits we find northeast
erly winds on the foremost side of cyclone,on
the 14th and 18th, changing to winds of the
back half on the 10Th to 18th, returning to
trade-wind on the 18th and Doth.
Lastly we notice that the st. Croix wind
directions seem to be almost out of the
running. They were carefully noted, but
between calms and light southerly broezes
they are without any very definite story to
tell. St Croix was probably the most dis
tant from the cyclones centre of the islands
named and that is perhaps the reason that
it has so little to say. We noted, however,
that the low clouds on the morning of the
14th were moving slowly from east while
towards the end of the time under cOnsldera-
ton they were moving from southeast. The
study OF the above table of the winds seems,
when compared with the high cloud move
mentsto confirm the after, andtO show that the
cyclone commenced somewhere beyond Bar
bados, perhaps near there, and moved west
wards till on the morning of the 18th it was
about SIS. w. of st. Croix and later in the
day was south of Santo Domingo and south
east of jamaica. The barometer readings
only roughly fit in with the wind table.
They put Barbados first, but by about one
day only ahead of st. Croix, while the
second table put it between one and two
days in advance. The space moved over
would be about $50 miles to the morning
the 18th. II this were trsversed in a day
it would be at 20 miles an hour, if in &c
hours it would be at less than ID miles an
hour, either rate is possiblo the latter more
probable.
1t must be clearly kept in mind that a
cyclone may be without a hurricane. II
you are afraid of the word cyclone you may
speak of a cyclonic disturbance. To this
class the movement here under considera-
ton belonged. It viii be noticed that the
Weather Bureau, in it's notice on the nth,
spoke of it as "a Disturbance. This leads us
to ask What became of itS
3. The later history. AS no information
has later come to hand, it is not possible to
do more than say what seems likely. We
left the high clouds on >uhday afternoon
coming from west. Now experience tells
us that if q cyclone causing them
were about to move out towards the north
into the Atlantic, the high clouds would also
shift their point of origin towards the north.
Even if the cyclone were moving west along
the Caribbean the same thing in a less
marked degree would happen. But it did
not happen, the next day the high clouds
were coming from S.S.W and the following
day from S.W. These are normal directions of
theseclouds, and it aid not appear that any
new cyclone hadarisento try conclusions with
the old one, hence we concluded that it's
power was gone, that the depression after
moving off to the west had filed up. 1t may
of course turn out that we are wrong; wealth
er problems are often complicated in a high
DECREE. and ONLY observations from several
