THE SUGAR BEET. 



and their analysis made, we will discover that the 

 short and fat ones contain far less sugar than the type 

 mentioned above. To express this idea geometrically 

 we will suppose an axis A B and a line cd forming an 

 angle y with the same (see fig. 17) ; evidently if this re- 

 volves it will thus engender a cone, if a curve a (5 (see

Fiff. 18. 



fig. 18) takes the place of this, the volume thus formed 

 will greatly resemble the rutabaga or roots having but 

 3 to 4 per cent, of sugar ; now, if this curve be con- 

 cave (see fig. 19), the surface will then represent a type 

 containing 15 or 16 per cent., or most favorable for 

 beet sugar manufacture. The necks in this case are 

 short and small, and in the other long and large. This 

 consideration holds good for the greater number of 

 cases, but, as Peligot first remarked, beets having many 

 small adhering roots contain more sugar than others
