some twenty years ago my attention was
attracted by newspaper article based on
the theory of an experienced English sea
captain, touching the theory of storms.
The point that struck my mind with
greatest force was that u storm was raging
at some pointCr place in the world all the
times and, that there were certain laws
which, If wecould learn and observe them,
would keep us as well advised of the place,
progress and destination of storms as are
our commercial men posted on the subject
'cf markets,
My thoughts on the subject were actively
reproduced by series of articles in Scri6-
ner's N0ptllV for the early months of this
year, NJ asenting the "Sea Captains"
theory ie quite a practical form. 1t was
well exhibited in the form of maps and
diagrams and, to make the risk oftrying
to statelin fewywords, the substance of the
much vaat was ably presented, L will say,
that a=5trong or heavy pressure OF the at
mosptere at any given point is at the eX-
pense of light or rare atmosphere around
that point. Taking, then, the place of
! greet lest atmospheric pressure, and describ-
| ings. circle about it so as to embrace fully
circle will constitute the inside margin of
a circular belt upon some part of which a
storm is progresSing-itS force and Vio-
lencce depending upon the measure of pres
sure and the length of time it has contin-
ued. Why this is so? And another item.
Why the course of a storm on such circle
is in n direction as adverse to the move
ment of the haIds of q watch, north
of theequator, and with the hands of the
watch south of the equator? are two very
interesting questions. Theoretical writers,
thus far, have scarcely undertaken, but
not succeeded in giving Il satisfactory eX-
PLANTATION,
If space would admit | would like to pre-
sent my theory on both but l will only
make a comprehensive reference to the
first The action of the upper and lower
Trade Winds upon columns of air rising
rapidly under the influence of evaporation
and heat, is manifestly the cause of the air
| being thrown into circles. The upper and
| lower stratas of air being cut and drifted
in contrary directions; and then, what is
| singular a section of air at given place
| being set in motion seems to provide for its
| continued progress and accelerated speed.
| But however this may be, the fact isknown
that atmosphere runs in circles-whirl-
| winds on a large scale. When the volume
Of circularly moving air is large-broad
and higli-the tendency is to pack and
compress the air about the place of the cir
| cle's center: and for the same reason, the
| the atmosphere about, aud just in front of
| the actively moving column, is quite rare
| the upper strata having been drawn of
4 to supply what we may style partial vac
Il uum in the rear of the column. This
rare section of atmosphere is in the form OF
au inverted cone, so to speak, it represents
the form of n basin, down into which ma
turallY flow and gather the vapors of all
the adjacent higher regions. and llaw
themselves poured out as the contents oil
the bosom of the storm.

letter, | must drop the subiect-or let il
y drop me-Only adding that the emnen
i success of the system OF reports from storm
: signal stations in the nited States for thu
: past few months, leads me to make thi
prediction: The day is not far distan
when our morning papers-the CHRONICLE
