SUPPLEMENT. 



(which is a cross-breed from the wedge-shaped Silesian white 

 sugar beet and the Magdeburg chicory beet), and the Qiiedlin- 

 burg variety, with pinkish colored skin and red lines in the 

 centre leaves, are particularly valued. The latter requires the 

 richest soil. The French Vilmorin sugar-beets, on account of 

 their superior saccharine property are also frequently raised ; yet 

 as they are more liable to degenerate in the pits during the 

 winter season, they are only cultivated to a limited extent, and 

 are worked before frost during the latter part of September and 

 October. The sugar-beet in its present state, a child of cultiva- 

 tion, is a variety of an unsightly biennial plant, beta maritima, 

 which grows wild along the coast of the Mediterranean, in south- 

 western Europe. A comparison of the following analyses of 

 the ash constituents of the wild and the cultivated plant gives 

 some idea to what extent a systematic cultivation for partic- 

 ular olyects, aided by climate and soil, may affect the normal 

 mineral constituents of a plant. The wild beet-root may be 

 called a soda plant, while the cultivated sugar-beet is decidedly 

 a potassa-plant.
