It Is the late or main crop varieties
Of spuds, intended for winter use,
which are stored, as the early or truck
| crop potatoes are ordinarily disposed
of directly from the field as harvested.
Potato storages are practically Of all
| types and descriptions, from primitive
shelters, such as caves or pits, up TO
rather elaborate, artificially refriger-
ated storage houses. However, the
| fundamental purpose Of the storage
house, be 1t simple or elaborate, Is
to protect the spuds from extremes of
] cold and heat as well as frOis: the
light, and under proper conditions Of
humidity and ventilation. Care must
be exercised not to keep the potatoes
together in large bulk where the devel-
opment of high temperature and de-
terioration will be favored.
Specialists Of the United States de-
partment of agriculture believe that a
temperature of about 36 degrees Fab
renheit is generally low enough for
practical potato storage, and that dur
ing the earlier portion OF the storage
season the temperature Of 40 degrees
Fahrenheit Is just as satisfactory ex-
cept where powdery dry rot Infection
occurs. The freezing point of the po-
tato is between % and 20 degrees
Fahrenheit.
Potatoes. when exposed to strong or
even moderate light are soon Injured
for food purposes, and on this nc
count 1t is essential to exclude the
light from the storage house, although
exposure to modified light, where the
spuds are kept cool and well aired. is
not Injurious to tubers intended for
seed potatoes.

quate ventilation must be made, the
ventilators or air fiues being arranged

tribution of air throughout the struc-
ture.
1t is a bad practice to store pota-
toes In large bins or piles. Not infre-

depth Of 10 or Is feet, the pile being
CORRESPONDENCE large in the other d.
mansions. Such storage almost in
variably results In violent sweating or
curing in which the spuds In the CEN
trail postion Of the pile are frequently
subjected to dangerously high tenn
perature. This Is especially true II
the tubers are slightly Immature or
were not dry and free from moist soif
when gathered, or II stored when the
outside temperature was high, making
1t difficult to lower the inside temper
AZURE Of the house. Such overheating
may be avoided by inserting division
walls at intervals throughout the pile.
The division walls may consist Of
2 by inch uprights, on the Pinch
face of which are nailed u by inch
strips of any desired length, leaving
1-inch space between each strip.
This provides ventilated partition,
which can be Of any height and length
desired. BY placing these In an up
right position to 8 feet apart as the
bin or storage house is being filled,
good ventilation will be secured and
an easy avenue Of escape for both heat
and moisture provided. G..
Storage Adapted to Local Nesda
In. considering the type OF storage
best suited to the needs the grower
should bear In mind the temperature
and rain or snow likely to occur dur
ing the storage period, the character
and cost Of the material involved
the nature Of the soil and drain
age. and the length Of the stofast
period. Potatoes may be pucQesS
