THE WIND VANE
Is one of ordinary size and construc-
ton, which is soon to be replaced
with one larger and more sensitive
The direction of the winds is of great
importance as q weather sign. In
atmospheric disturbances of a gen
eral nature the tendency of the winds
on the borders Of the storm area is
developing in the northwest atLouis-
vile, it is preceded by a continuous
southeast wind. Similarly IN a storm
approaching from the southwest
ward, a northeast wind blows with
equal persistency. The wind is
equally accommodating in giving
notice Of the termination of "bad
spell" a northWesterly wind being
premonitory to rising barometer
and clearing weather.
THE ANEBIoMETER
Is an ingenius arrangement for
measuring the force of the wind. For
light, metallic, hemispherical cups
are fastened upon two rods crossed
at angles. The rods at their inter
section rest firmly on an upright
spindle, upon the lower extremity of
which there is an endless screw,
which works two toothed dial-plates.
Allowance being made for the weight
of the rods, resistance of the air and
friction, it has been found that five
hundred revolutions of the cups are
equivalent to a mile of wind. The
two dial-plates are placed one over
the other. The scale upon the outer
plate is divided into miles, and from
this the hourly velocity is obtained.
The scale upon the inner plate reg
listers to one thousand miles. The
daily velocity Of the wind is obtained
from the latter place.
BULLETINS AND RECORDS.
| Five regular observations are ta-
ken daily-at Z A. NJ, 2, 4, 9 and IL
2. NJ. Each observation is practi-
cally photograph of the weather at
the time-the temperature, moisture
and pressure of the air, the direction
and force of wind, the fall of rain, the
lamount of lower cloud, the amount
and direction Of upper cloud-all be,
ling given explicitly. Then A. NJ.
4 and IL P. NJ. observations are tel
egraphed to Chicago and thence tc
all the stations using the Louisville
report. At the same hours report;
from thirty stations are received, ,anC
from these the morning and evening
bulletins and press reports are made
At 8 o'clock at all river stations, al
observation of the stage of water il
taken from the standard loca
guages, and sent with the Afternoon
report.
In addition to their value a
weather intelligence, the observa
tions of the signal service have i'm
portance and permanent records
! They are all entered in the 'Dail
Record of Observations" and tn
entries for each week duplicated an
, forwarded to Washington. At tn
same time, there is also made dis
,, /, gram or chart which is an uniqu
, history Of the weather of the month

Of equal parts the positions of a
the instruments at every observation
are separately located. The point
thus fixed are joined by lines whicl
present to the eye undulations col
responding to the motions of tn
several instruments. The chart is
