The changes of weather which are
constantly taking place are not irreg-
ular and accidental. They occur &C
cording TO certain laws, and as the re-
suit Of certain causes. By ascertain
ing these causes, il is possible 10
predict changes, so that storm, or
cold or warm wave of temperature,
may be foretold some hours before il
appears.
The provision made by the niteL
States for noting conditions, and an
nouncing indications. in all parts OF
the country, is Of great Importance. Ii
Is Of great value in agriculture. The
farmer. relying upon these indications,
may select favorable weather for plant
lng his seed or harvesting his crops.
Sfarms.-The central section Of
storm is noted by an area of low ha.
rolneter, or low pressure That is to
say, ii is where the atmosphere is light
er than usual, and on that account is
rising. In front and in the rear of the
storm center, the barometer is high. or
the atmosphere is heavy. In the nited
States, these sections OF low pressure.
which mark the location Of storms. are
generally long aud narrow. extending
across the country from north TO south.
Storms usually appear first in the
western or southern parts of the coun-
Try. and move in an easierlv or north
easterly direction
Naturally, the winds on both sides
of the storm center blow toward it
They are the heavier sections of air
passing IN to take the place Of the
lighter sections. which are rising
hence. storms are generally preceded
by east, northeast, or southeast winds.
aid followed BY west. northwest, or
southwest winds.
Ciimate.-The climate of a region
IS its condition with regard 10 heat and
moisture II may be considered hot
or cold, moist or dry climate
The temperature in any locality de-
ponds chiefly upon the following con

!. Laf1ude.-The extent to which
the earth and the atmosphere near it
become heated depends upon the d.
rectness with which the RAYS of heat
tram the sun ialI upon il. Sections rear
the poles are therefore colder than
those near the equator which have the
sun more directly overhead.
,. EierHtton.-As the atmosphere is
cooler the higher We ascend. so the eli
mate of elevated tracts is colder than
that of plains and valleys. AL
though the high regions receive the full
benefit of the suns heat. they lose heat
rapidly, since the atmosphere in these
regions, being thin and dry, permits
the heat to pass off easily by radiation.
3. Aearness 10 the Ocean.-The ten
dency of the ocean is to render the eli
mate uniform, cooler in summer and
milder in winter. As the water upon
the surface of the ocean becomes heat
ed by the sun, it mingles with the cool
er water below. This prevents the sur
face water from becoming very warm.
and from imparting heat rapidly to The
atmosphere.
As the ocean has stored a large
amount of heat, ard has become heated
to considerable depth, il is not quick
ly cooled as winter approaches, but
parts with its warmth gradually during
the entire winter.
The solid land, on the other hand,
does not become heated to a great
depth. The heat of the sun is concen-
trated upon its surface. and is more
readily radiated into the atmosphere.
In the fall of the year the ground is
more quickly cooled, and has less in
tiuence in tempering the severity Of
winter
Near the coast, the climate is rem
dered comparatively uniform by re-
ceiving the benefit of cool winds from
the sea in summer and mild winds in
winter.
The amount O., moisture depends
mostly upon the nature of the surround
ings and the direction of prevalent
winds.
Hilly and mountainous regions,
which the winds reach first in their
usual course, are generally well sup
piled, while more level regions farther
on have a drier climate Winslow's
