Per Cent, of Sugar and Purity of the Juice Influenced by 



Size of Beets. 



In general the smaller the beet when mature, the higher the per 

 cent, of sugar and purity ; and the larger the beet when mature, the 

 lower the per cent, of sugar and purity. 



Sugar beets may be so small that it would not pay to grow and 

 harve.st them. They may also be grown too large and coarse to be 

 profitably used in sugar making. Between these two extremes there 

 is a size of beet that can be most profitably grown — this ranges from 

 ji^ to 2 pounds. 



Per Cent, of Sugar and Purity of Beet Crowns. 



It is generally supposed that the per cents, of sugar and purity of 

 beet crowns are much lower than in the beet proper. In several cases 

 beets were taken and the crowns removed, and each analyzed sepa- 

 rately with the following results :
