| Thermometer, which has a dry bulb. If
the two readings are near together
the air is nearly saturated and should
the air grow cooler, rain is almost sure
to fall. But If the air is growing
warmer. there will be no rain, since
the capacity OF the air to hold moisture
increases with a rising temperature.
When the readings of the wet and the
dry thermometer coincide the air is
saturated, since it is the rate of evap-
Grafton that lowers the reading OF the
wet bulb. In recent experiment the
dry thermometer stood at q, and the
wet one at SEA difference of is de-
grees, showing that the atmosphere
contained only 36 per cent toward COM

precipitation will occur
HIGH AND Low PRESsUREs.
The direction and force of the wind
and the pressure of the air are the
best guides for predicting the weather,
Prof. Garriott of the weather bureau,
says:
AS low barometer readings usually
attend stormy weather. and high bar
ometer readings are generally associat-
ed with clearing or fair weather, it
follows that falling barometer indi-

ic waves OF crests (areas OF high
barometer) and troughs or depressions
Gtreas of low balpmeter, are by ma
tural laws caused to assume circular
or oval forms, the wind directions
with reference to areas of low barome-
ten are spirally and contraclockwise
inward toward the region of lowest at
mQspheric pressure, as indicated by
readings of the barometer. Areas Of
low barometrie pressure are, in fact,
whirlwinds of greater or less magnl-
tude and Intensity. The atmospheric
erests. or areas of high barometer. on
the contrary show winds flowing spir-
ally clockwise outward from the region
of highest barometric pressure"
FoRECAsTING THE WEATHER.
'As a rule, winds from the cast
quadrants aud falling barometer indi-
cate foul weather; aud winds shifting
to the west quadrants indicate clear
ing and fair weather The rapidlty OF
the storms approach and its intensity
are Indicated by the rate and the
amount IN the fall of the barometer"
