"Bruised fruit were classified as slightly, moderately, or seriously damaged 

 according to the criteria employed by Burt (Burt, S, W,, 1959. An experimental 

 packing line for Mcintosh apples. U.S.D.A., A. M.S. Report No. 330) for the 

 Mcintosh variety. The number of apples with stem punctures were recorded with- 

 out regard to bruising. The percentages of damaged apples, according to variety, 

 type, and degree of damage arp. summarized in Table I. The values of damage at 

 the end of the conveyor include the damage of unloading as well as conveying; 

 the values of damage at the end of the drier include damage of unloading, con- 

 veying and drying. 



Table I - Average Percentage of Fruit With Bruises and Stem Punctures After 

 Unloading From Bulk Boxes (Values for End of Conveyor and End of Drier are 

 Accumulated Damage to That Point) 



"Less than half of the Mcintosh, and approximately one-quarter of the 

 Golden Delicious apples, taken from the water before passing onto the conveyor 

 were damaged. Most of this Injury was slight bruising, and could have occurred 

 to a considerable extent in the boxes before unloading. This factor, however, 

 was not determined. 



"Bruising was increased slightly on Mcintosh by passing over the conveyor 

 and almost doubled for Golden Delicious; however, passage through the drier 

 added much bruising to Mcintosh and a relatively small amount to Golden
