VARIETIES OF THE BEET. 73 



Silesiaii, etc., improved as the yield is supposed to be 

 greater. The percentage of sugar remains constant. 

 These have no small roots and grow well under ground 

 when the soil on which they are planted is suitable and 

 thoroughly worked. The average yield is 50,000 kilog. 

 (110,000 lbs.) to the hectare. 



We now have several types created by Simon Le- 

 grand, the most important of which is the " Franco- 

 AUemande." This variety is white, and has a green 

 or rose neck, and contains from 18 to 14 per cent, of 

 sugar. It requires a deep subsoil. There are also a 

 great number of sub-varieties not of the same interest. 

 Of the less important types existing in France might 

 be mentioned " Bettrave dit Dervaux" and " Bettrave 

 dit Toilet," each of which claims from 13 to 14 per cent. 

 of sugar, and last of all in England the Improved 

 Carter^ sugar beet, which is supposed to give a high 

 percentage of sugar. 



' Experiments which we made In Pennsylvania and New Jersey were not 

 satisfactory with this variety.
