CHERRIES 



Freezing-point determinations were made on three sour and two 

 sweet varieties of cherries grown on the Arlington Experiment Farm 

 and two varieties of sweet cherries from California. Special interest 

 is attached to the freezing points of the sweet varieties (table 1). 

 Determinations were made on both fully mature black fruit of the 

 two California varieties and on bright-red fruit which, although 

 immature, is often shipped to eastern markets. The immature bright- 

 red cherries were quite sour, whereas the mature dark-red to black 

 fruit w T as sweet and of good eating quality.
