EXPERIMENTS WITH SUGAR BEETS. 
9 
The Societe Centrale de l’Agriculture, du Pas-de 
Calais, have agreed upon the following standard: 
Specific gravity 1.045 yields 8 per cent, sugar.

This standard must be unfair, as the yield of sugar 
is increased disproportionately in rich juice ; on the other 
hand, the juice may be high in other salts and poor in 
sugar. 
The highest specific gravity as given by Dr. Wiley 
in the analyses of ten samples of the best California 
sugar beets is 1.075 White Imperial, and it corresponds to 
15.19 per cent, of sugar; while there is one sample, White 
Silician, having specific gravity 1.074, which gives 15.85 
per cent, of sugar; and another, White Imperial, specific 
gravity 1.067, which gives 15.19 per cent of sugar. For 
the reason above given, the specific gravity is not always 
a correct index of the per cent, of sugar, as the following 
analyses of varieties raised on the College garden will 
show:
