5. No varieties should be commercially planted without a searching 

 investigation by the grower of their merits from the standpoint 

 of both tree and fruit qualities and particularly with respect to 

 their adaptability to the locality where they are to be planted. 



6. Better varieties are needed in most districts, 



7. plant well-grown, vigorous, healthy, virus-free trees with uniformly 

 strong, congenial rootstooks. 



8. An increase in the yield per acre of a good grade of fruit is impera- 

 tive. 



9. Every effort should be made in cooperation with public sind private 

 agencies to reduce the con^^lexity and cost of production and marketing, 



10, The growers need to assume more responsibility for the condition of 

 fruits as delivered to the consumer. 



In future issues of Fruit Notes these recommendations will be 

 discussed further,

APPLE STORAGE COOLED BY NEVf METHOD 



After months of exhaustive tests, a large apple storage in the 

 Wenatchee district in Washington is now being cooled by what is known as 

 the reversed air method. In this storage which holds 260 carloads and 

 looks like a civic auditorium, a huge blast fan pumps 50,000 cubic feet of 

 air per minute past great banks of cold pipes. The air goes through one 

 set of ducts for three hours and then is reversed automatically when a time 

 clock sets the machinery in motion which shifts the dampers and sends the 

 air in the other direction. The intake ducts thus become outlets, and the 

 air passes through the rooms in the opposite direction. This makes it pos- 

 sible for air at a temperature of 26° to be blown through the rooms because 

 its direction will be reversed before the fruit near the intake ducts is 

 frozen. 



The temperature of the air rises a few degrees as it travels across 

 the room although every three hours the direction changes and the warm side 

 becomes the cold side. Extensive tests have shown that less than one degree 

 difference in fruit temperatures will be experienced in any part of the stor- 

 age room, - corner, center, top or bottom. This new method, therefore, 

 means not only quicker cooling but more uniform cooling. 



Believing that the whirling compressors are the most impressive 

 part of a cold storage plant, the architect has placed them in this building 

 where passers-by csin see the wheels spin. A huge sound-proof plate glass 

 panel separates the manager's office from the compressor room. Every con- 

 ceivable modern feature has been built into the plant to keep pace with the 

 new reversed air installation, and to improve the quality of the product 

 during the highly competitive years ahead.
