Processing and Utilization 



Hawaii The Drying of Coffee Beans . To (l) learn design require- 

 ments for driers capable of greater economies and efficiencies 

 in processing and increasing coffee quality; and, (2) obtain 

 data on thermodynamic properties of coffee while drying, and

Disease Control 



Calif. Orange ttee Quick Decline; Roots tock Scion Relations 



Affecting Its Occurrence and Prevention . Methods to be used 

 include determination of the susceptibility to quick decline 

 of commercial citrus scions on varioiis rootstocks, topwork- 

 ing to non-susceptible tops, inarching with resistant root- 

 stocks, and roots tock identification in investigation of: 

 (1) degree of susceptibility of various stock-scion combina- 

 tions including sweet orange, lemons, grapefruit, and miscel- 

 laneous scion varieties on sour orange stock; (2) the effects 

 of topworking susceptible sweet orange trees to other species 

 of citrus including degree of response after topworking trees 

 which are free of symptoms and those showing symptoms of vari- 

 ous degrees; (3) the effects of substituting resistant root- 

 stocks for susceptible so\ir orange roots on sweet orange trees 

 by inarching; and, (k) identification of rootstocks.
