 Note galvanized iron ventilators in concrete foundation. This house has a covered plat- 

 form on two sides. 



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- 

 torj% 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. 



Storage Boom 

 "Cool" Storaire 



Several combined packing and "cool" 



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
