Reports are that the damage is heavy in places.
For example, two experts of the crop reporting
service In Missouri estimated the damage to fruits
and early vegetables at $l0000,000.
The apple crop in Washington, Benton, and 9TH
er counties In the northwest Arkansas fruit region
will be practically total loss. Peaches and cher
ries were killed and Strawberries damaged almost
so per cent
Dispatches said about 95 per cent of the fruit
crop In Oklahoma Is ruined.
= Ii Is estimated that Nebraska's crop of early
cherries, apples, pears and plums is total loss
The early varieties of fruit In some eastern
states also suffered heavily
Early peaches, cherries, and plums probably
have been killed In southeastern Pennsylvania.
The cold weather seriously damaged the fruit
crop in the southern part Of Ohio, where the fruit
was far advanced.
Thousands of Maryland fruit trees were in full
bloom when hit by this frost Growers in Wash
ngton county, the center of the western Maryland
peach belt, report the peach crop destroyed.
The fruit crop in Kentucky apparently was
killed
Therefore the following article prepared by
the United States Department Of Agriculture Is
worth the attention of every fruit grower:
The weather bureau of the United States De-
partment of Agriculture has been able to discover
the weapon used by that old enemy of mankind
Jack Frost, and in recent published report 1t
tells the farmer and fruit grower just what Jacks
invisible weapon is, and how under ordinary con-
ditions, the sprite's own artillery may be used
against him.
Frost, of course, occurs whenever the mercury
drops to 81 degrees +. or lower IL much mois-
ture is present In the atmosphere this drop in

"freeze" is the term applied to condition of cold
more permanent than frost, and such condition
may occur when there are high Winds True
'frosts" occur only when the surface air il rel

Temperature, like water, seeks level During
the day the earth receives more heat than II can
throw off but at night this supply of heat is
stopped. During the day the heat thrown off
by the earth warns the thin blanket of air next
the ground This blanket as 1t warns loses its
density and ascends. Cooling as 1t rises present

there 1t stops. Meanwhile Its place has been
taken by other colder air, which is in turn warmed
by contact with the ground. This exchange goes
on until, at shutdown, all the air of wide layer
above the earth has been warmed, and the high
est temperature Is felt nearest the earth.
Earth squanders Its Heat
Nows with the sunset, old earth begins to suffer
from a bit Of aerial trckery. All day long he
has been patiently passing out heat to one cold
air layer after another; night comes, and with
