A CHEMICAL STUDY OF CRANBERRIES

shipped to the laboratory. It was not possible to analyze the varieties simul- 

 taneously nor rapidly with regard to time. Hence both maturity and respir- 

 ation were variables in the life of the cranberry and must have exerted more 

 or less influence on the composition. 



Variation due to stages of maturity is most apparent in the range of 

 composition within a variety. This is because the diflFerences between samples 

 are commonly larger than those which actually have been found to be due to 

 storage. For example, Champion v\as represented by three samples: one was 

 analyzed November 27 and contained 4 per cent of sugar, two were analyzed 

 in February and shoMed over 5 per cent of sugar. The low percentage of 

 sugar must have been due to immaturity at the time of harvesting that 

 sample.
