PREFACE 



This study brings up to date a 1941 survey of cold storages in the 

 apple-producing districts of north central Washington. The objective is to 

 provide the apple industry with data helpful in planning its storage and 

 packing programs. With the information contained in this report and a good 

 estimate of the expected crop, apple growers should be able to estimate 

 whether or not they will need to seek storage space outside their respective 

 districts considerably in advance of harvest.

SUMMARY 



A tabulation of apple storage cooling capacity and refrigerated storage 

 space in the north central Washington district shows that, in the last 

 15 years, capacity and space have about doubled. In most shipping areas, 

 production has not substantially changed. The increases in capacity and 

 space have relieved nearly all the inadequacies that existed in 1941. In 

 one district where production has increased, the storage cooling capacity 

 and space, in spite of a threefold increase, is such that it is necessary 

 for growers to seek cold storage space outside their area. 



Although the installed storage capacity is approximately 21,000 carloads, 

 use of a part of the space for pear storage and the greater space requirements 

 for fruit held loose indicate that some common storage will be required when 

 the apple crop reaches 18,000 carloads or more. In 1955, a fairly normal 

 year, the crop was 15,600 carloads, but production varies widely from year 

 to year.
