Facts to be Remembered-1. The approach of
local frost can be foretold with very consider
able accuracy from the readings of properly
exposed dry and 'Cet thermometers.
2. A safe and simple rule to follow in pre-
dieting frost when the temperature is at 500 or
below is to multiply the difference between the
readings of the thermometer by %, and when
the sum thus obtained is subtracted from the
reading of the dry thermometer it leaves the
approximate degrees to which the temperature
of the air will fall the coming night, unless
change of wind to a moister quarter or increase
of cloudiness interferes.
3. Since this lowering of temperature is
caused by radiation, it follows that any method
which will prevent free radiation must materi-
ally check the formation of FROST so that even
thin cloth, layers of straw or even a cloud of
smoke viii protect the tender plants, unless
the frost is very severe.
