1. The Effect of Temperature on Cranberry Keeping. 

 Table 4 shows the amounts of rot that developed among different lots 

 of sprayed and unspraj^ed Early Black berries kept at different tempera- 

 tures, some in open and some in closed one-quart cans. All the berries 

 seemed sound when put in the cans. These tests were carried out in 

 Washington, with Brooks and Cooley's temperature apparatus.^ The 

 softening among the fruit was in all cases greater with the higher tempera- 

 tures. Table 4 shows like results in tests wdth Howes berries.
