understand its action, think of theli
air as q great ocean like water, but
much lighter, entirely Surrounding
the globe. Z The sun shines upon this .
ocean of air, and through it on theEil
earth, heating. them both, and rim-
partfng most heat at the eafth's sur
thce. But the suns rays shine more
q 'rectly, down on some Darts than en-
9th ers, and therefore heat them more, 1i
Thus, it is always hotter in the re-
gion of the equator, than at the poles.
Now heat expandsa fluid, making &c
lighter, and when part of the air is
expanded by heat, it rises, ana stne
cooler, heavier surrounding air rlsn..,s..
es in to fill its place, and thus WIND
is produced. The followlng SIM PIE
experiment will show Just hoE5othis Z
works. Fill large tin pail with va
ter, in which scatter some fine bread
crumbs. Place burning lamp under
the MIDDLE Of thepail. and the crumbs
win soon begin to rise, carried up by
the heated column Of water, and then
making q curve toward the sides, will
sink downward, and pass in q hori-
zOntaI direction along the bottom,
lust as wind drives along the earth's
surface, In s room containing hot
stove, drop into the air in different
places bits of light cotton, or dry
thistle blossoms, and you will see how
the air Is moving at each point.
If the earth were all a plain, and
each part received a regular unchang-
ing amount of heat through the year,
the currents of air or winds would
always move in one direction. But
many things prevent this. The land
is more heated than the water by the
SUMS rays some soils also absorb
heat more readily than others then
at night and during cloudy weather
when the source of heat is cut on, the
heat is radiated or passed out une-
aually from different localities, ana
this produces variations in the cur
rents. Mountains, and valleys also,
change the courses Of the winds, and
other causes, such as the. varying
moisture in the air. and probably us

tainty which way the wind will
blow tomorrow, and "fiekle as the
wind, - has come to be prOverb. On
the ocean where no mountains inter-
vene, and where the heat is quite
uniform, currents of air called trade
winds blow steadily in one direction
Their course in the northern heml-
sphere is from northeast to south
west, in the southern hemisphere
: from southeast to northwest. These
steady winds are of great service IN
navigation or trade, as ships are some
times enabled to glide before them
for weeks without changing SAIL
New discoveries are'being made al
most every year, and perhaps at some
, time in the future men may ee aoIe
to foretell the direction Of the wind
at present, we can only try and make
the best of it from whichever quar-
ter it comes; though that IS little
difficult on some March days, when
it seems to blow from all quarters at
once.
