inches deep. 1t is lined on all sides with gal
vanized sheet iron, has a stone sill in the bot
tom, and is furnished with two slate slabs fpr
shelves on which to place the printed pounds
of butter to harden before packing for mark
ct. These shelves are Is inches wide, or three
inches narrower than the depth Of the cup
board, so as to permit a free circulation of
cold air around them. BY means Of the Stat
ted blinds, or ventilators in the top and bot
tom pannels Of the cupboard doors, shown in
figure 8, representing the doors both open
and closed, a circulation Of air in the milk
room is created and maintained, keeping it at
a uniform temperature of GEO. The warmer
air near the ceiling entering in through the
top lattices and being cooled by contact with
the ice box sinks to the bottom of the cup
board and passes out cooled through the low.
or lattices into the milk room to fill the place
made vacant by the warmer air rising to the
ceiling. This constant and continual circula-
ton of the air is maintained until the proper
temperature of 60o is secured, when the blinds
are closed, circulation checked, and the tenn
peratnre in the cooling cupboard is lowered
to $40, or lowerif desired As accessories in
this refrigerative plan, the ventiating pipes
7. S., figure 2, whose registers are shown in
figure 8, marked r. r., communicate directly
with the air chamber npder the ice box, and
with the air flues at each end of the ice box,
extending perpendicularly to the square of
the building BY this arrangement two adj
ditional currents of cold air can be admitted
into the milk room when needed. The win
dows of the vestible and milk room are
located Immediately under the ceiling and
above the surface of the ground outside
They are feet long and IL inches high. The
window frames are made of heavy pine scant-
ling, containing three rabbets each. The first
or outer one for the frame covered with wire
cloth to keep out insec the second or CEN
tire one for the glass sash and the third or
inner one for the shutters or blinds. The
whole is so constructed that the inside blinds
can be closed just as well when the glass sash
is raised as when 1t is down, and all sunshine
can be kept out of the milk room IL desired
and through ventilation be secured
8. PRACTICAL OPERATION Dairy
House has been in operation since July 1st,
1874. Whenever the temperature Of the air
out doors falls to Geo orlower during the night
no ice is needed in the ice box, for by opening
the windows at night, and keeping them clos
ed during the day, the desired temperature can
be secured. During the continuance of heat
ed term, when the mercury ranges among the
nineties during the day, and does not fall be-
low 75o at night, then from ten to fifteen
bushels of ice per week will be required, fill
ing the ice box two or three times a week ac-
cording to the intensity and duration of the
hot spell. The Ice House this season has sup
piled dairy on aneighboring farm with four
bushels per week, the water cooler daily for
drinking water for large family, and the
dary-house whenever needed with from five
to ten bushels per week since July 1st 1874,
the ice is four feet deep in the ice house, suf.
ficient for at least another month of hot
weather.
DRYSEss OF THE AIR IN THE MILK Room.
The circulation of the air against the cold
surface of the ice box rapidly abstracts the
moisture from the air in the milk room, which
is condensed and conveyed to the pool below.
So dry is the atmosphere that the stone floor
will dry in few hours after being washed
and this cool, dry, pu.e air is one Of the chief
