WHY WE HAVE CYCLONES.
They Must Increase Every Year Until We
Plant Trees.

In the SCleltlnc column OF q chicago
Journal, of July 4, it seems that the
whole theory of cyclones was clabo-
rated in u couple Of lines. In an arti-
Gle for the history OF Chicago (vol. /.
p. jSS), the writer gave the following
suggestion: "But Chicago has been
si%ngularly free from the devastating
cyclones that have cut swaths of ruin
in all the contcrminOus country, aud
the reasonable solution OF the fact
appears to be that the light atmosphere
of the lake absOrbs the approaching
cyclone and disScminatesit. The force
Of u cyclone, as The force OF dynamite,
requires repression and compression
TO educate it," In this necessarily
brief allusion the two great factors of
cyclones, SimOonS, northcrs or other
other cereal commissions, m stated
negatively. But in these marvellous
natural commissions all the p~ostulatcs
nave to be expressed in that manner
In fact, TO speak of the ''force" of a
cyclone is almost TO use 4 miSnomer:
for its force is not that of propulsion,
but Of exhaustion.
Take the winter Of Texas, the "nor
ther", as All example. The hot South
crn SUI for days and days beats upon
the ~trcclcss plateau of GEL Llano Esta-
cado," or the Stakcd plains, and as an
inevitable consequence the air becomes
exceedingly rarciicd and expended.
This expansion continues until the
S~upcrGcatcd portion is met by 4 mass
of cool atmosphere, and then the nat.
ural effect of cooling and condensation
of the heated air cnsuc This creates
q vacuum, which hiatus is filled BY Il

On the same principle as that of the
cooling sea breeze, explained in every
work on physical geography. Should
heated ali, then the continuous con-
air makes the "northcr." The same
causes produce the same results in
both the cyclone on land and the tor

uninterrupted rarclaction Of the ain
and the consequent cyclone. Nebraska
used to be uncnviably distinguished
by the violence and frequency of its
WindStOrmS. How man of thcs,
unpleasant %visitations has that State
had since the comprehensive tree
planting that has been carried on there;
1t would seem that that case alone
was sufficient proof for the successful
demonstration OF this axiom, without
any purely scientific reasons being
adduccd. But, ifany reader has not
been to Nebraska, or has had no OPP
portunity to consult the statistics rCia-
tive to that State, the cyclone theory
advanced is easily proved by visiting
any large furnace. Go there and get
the fircmcn 10 opcn the door OF the
furnace and listen for the result; the

Antagonists Of our theory have al.
duCcd the simeon as a simeon as a
COntravcntion of its being a scientific
fact, but, however, comforting the
apparent contradiction may be to tho
"Robbcr Lumber BarOnS", il is, il
faci, no substantial allegation adverse
to the theory at all. The fact that the
simeon is an intensely hot sandstone,
while the northcr is a very cold wind,
negatives nothing, for pyrology has
not yet demonstrated how hot air can
be made; and it is only nccdtu.l that
II section of atmosphere shOnld be
hotter than the air in its vicinity for
the heated portion to ascend and its
location 10 be supplied by the cooler.
And these simOons always occur on
the deserts, where there is absolutely
no forestry.
Hence, as it is impossible to trans
plant the lake which has proved the
safety valve for Chicago-to the cy-
clomc-inicsted regions, the only means
for their abrOgation and ultimate pre-
vcntion is to inau@uratc an extensive
system Of trcc-planting and prcscrva-
ton, and then and not until then
will the terrible devastation of the
cyclone become a thing Of the past. 1t
is the acme of stupidity to imagine
that any part of the fundamental laws
of nature can be set at nought without
the dircst results following, and Just
how any nation can infer that the
whole CONFORMATION of n country can
be changed without a corresponding
change accruing to the atmospheric
condition Of that country is hard TO
