Vermont, clear to the Canadian boundary
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 $10000,OO0
The apple crop in Washington, Benton and 9th
err counties in the northwest Arkansas fruit region
will be practically total loss. Peaches and cher
ries were killed and Strawberries damaged almost
80 per cent
Dispatches said about % per cent OF the fruit
crop in Oklahoma is ruined.
II is estimated that Nebraska's crop of early
cherries, apples, pears, and pums is a 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
ington county, the center of the western Maryland
peach belt report the peach crop destroyed.
The fruit crop in Kentucky apparently
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 n recent published report 1t
tells the farmer and fruit grower just what Jacks
Invisible weapon is ana now, ulluef ordinary CON
ditions, the spre's own artillery may be used
against him.
Frost. of course, occurs whenever the mercury
drops TO 30 degrees f. or lower If much mois-
ture Is present in the atmosphere this drop In
temperature is manifested by the white crystals
OF frozen moisture upon leaf grass stem, and
there is what is known white frost" If the
temperature drops TO the required degree and
does not reach the point when water from the
air is condensed there will be few crystals tie
posted, and the result is "black frost" A
freeze" is the term applied TO condition of cold
more permanent than II frost, and such n condition
may occur when there are high Winds True
"froSts' occur only when the surface air is rel
Otivey calm.
Temperature like water, seeks level During
the day the earth receives more heat than il can
throw OF, but ut night this supply of heat Is
stopped. During the day the heat thrown or
by the earth warns the thin blanket Of air next
the ground. This blanket as 1t warns, loses its
density and ascends. Cooling as it rises, present
~ II encounters air of its own temperature, and
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 a wide layer
above the earth has been warmed and the high
est temperature is felt nearest the earth
Earth squanders It's Heat
Now 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 cold
air layer after another; night comes, and with
II the loss of his source of supply, but do these
warm upper layers pass back any of the heat they
begged during the day? They do not-uness
they are made to. The layer close to the earth
does and thus they leave their coolest blanket
against the shiverng earth while they sail about
