Work Room 
The important point in the construc- 
tion of the work room is to furnish good 
light for the graders and packers. This 
can be accomplished by a row of windows 
along the side, by skylights in the roof, 
or by a combination of both methods. 
Where side windows are used entirely, a 
north light will be found most satisfac- 
tory, because most even. Packers should 
not be expected to work in direct sun- 
light. In large areas of the Northwest 
apple growing sections it is now possible 
to install electric lighting in the packing 
houses, and this should be done wherever 
possible for use in the late afternoons of 
dark days. Another point to be looked 
to is ventilation without draughts that 
will disturb the wrapping paper. Con- 
venience will be determined to a great 
extent by the disposal of the grading and 
packing furniture. Provision may need 
to be made for heat if the room is to be 
used in the late fall or the winter.

This house has a covered plat- 
storage houses have been built in vari- 
ous orchard sections of the Northwest 
within recent years. The principle of 
“cool” storage consists in the use of 
night air for maintaining a low tempera- 
ture during both night and day. 
The “cool” storage room or building 
is insulated in the same manner as a cold 
storage room. Three or four inch-thick 
dead air spaces separated by partitions of 
moisture proof paper over shiplap are 
said to serve as well as cork, at the 
same time being cheaper. Some of these 
plants, notably in the Payette, Idaho, dis- 
trict, are built with basements to be used 
for common storage, in which case air 
is taken into the room above, the “cool” 
storage room. proper, through openings 
in the walls just above the floor. In one 
room in the Yakima, Washington district, 
which room has been built into the base- 
ment of a warehouse, the air is taken 
in through a chute reaching down from 
the outside and extending along under a 
false floor consisting of planks laid an 
inch apart, the air entering the room 
through these cracks. In the case of two
