A few words about barometer readings to
close. An approaching cyclone causes q fall
in the barometer two or three days ahead.
The fall is not serious until the centre is
approaching, then it increases considerably
aud quickly. In the hurricane Of August
1899 the total fall in BossIn was nearly an
inch, in West End it was moro In many
Santa Cruz homes on that |eyenttul night
the barometer was watched With IN interest
it had never aroused before, and great was
the relief when it was first noticed to be ON
the rise, for then it was known that what
ever mighty gusts might yet come, the
hurricane had begun to move away.
