In each case, it is stated,* meditmi-sized roots were chosen 

 for analysis, as likely to represent an average crop. These 

 were grown on vlei land heavily manured with kraal manure. 

 With the exception of Cooper's Silesian. the roots were regarded 

 as not perfectly matured. 



Later in the season further samples of roots from other 

 localities were analysed. The results obtained were as follows : —

It will be seen that in several instances the percentage of 

 moisture is no higher than in the samples analysed at Capetown 

 and Grahamstowti. 



If any i)art of Soiuh .Vfrica is going to become a beet-pro- 

 ducing country, it is clear that we have much to learn on the 

 subject of beet culture and its adaptability to our conditions. 

 Cultivation in luirope has greatly altered the chemical com- 

 position of the sugar-beet, as I have pointed out on former occa- 

 sions. But cultivaticMi has not only altered its sugar content. 

 Ingle, in Thorpe's " Dictionary, "t sa\'s that " the proportion of 

 ash is much lower than formerly, and the ([uantity of potash 

 is only about half of what it was, while the soda has doubled." 

 These are ini])ortant points : with potash rendered a scarce 

 commodity by the war, the potash re(|tiirements of a crop need
