' The results obtained by analysis were : — 



Beets untouched. Beets stripped. 



Water 85.600 88.250 



Sugar 9.320 6.210 



Nitric elements . . . . 4.360 4.559 



Mineral salts .... 0.719 0.981 



100.000 100.000 



* Schwartz, a Belgium agriculturist, considers that if 100 represents roots 

 untouched, 98 would be the yield if stripped once, and 58 twice, etc.
