Mass , Processing and Utilizing Mcintosh Apples and Cranberries , 

 (l) Learn nitrogenous constituents and thiamine content of 

 Mcintosh and other varieties in relation to efficient con- 

 version of apple carbohydrate to ethanol in preparation of 

 vinegar stock. Effort will be made to identify specific 

 deficient constituents and to devise practical methods of 

 correcting same. (2) Application of Hunter Colormeter to 

 grade cranberries and crsuiberry products will be investigated. 

 Influence of environmental conditions in various bogs on devel- 

 opment of red pigment of fresh fruit will be studied. Work 

 on quinic acid content of fruit will be completed, and a 

 search will be made for unknown acids in cranberry by applica- 

 tion of chromatography.
