to make it wortli wliile to keep it on permanently. This cane lodges 

 rather badly, but ratoons better than the ordinary soft '<^arieties of 

 cane that have been tried from time to time at Winkle Spruit. 



1. Yields of Sugar Cane per Acre frovi the various Plots. — All 

 the crops given in this table are from plant canes which had been in 

 for approximately two years before being harvested : — 



(1) Argentine: J.213 52 tons. 



(2) Argentine: No. 2 45 tons. 



(3) Argentine: E.G. 719 (first lot) 60 tons. 



(4) Argentine: R.G.719 (second lot) .... 41 tons, 



(5) Argentine: J. 36 39 tons. 



(6) Argentine: J. 139 37 tons. 



(7) Egyptian: Cheribon 41 tons. 



(8) Indian: Agual 51 tons. 



(9) TJba Over 30 tons. 



(2) Fields of Sugar frovi the different Varieties of Sugar Cane. 

 — In this investigation six typical canes were selected from each plot 

 and weighed. Each lot separately was then passed three times in 

 succession through a hand-power three-roller laboratory cane mill, 

 and all the juice carefully collected, weighed, and then analysed. 

 The results obtained are given in the following table : — 



In the above table the following terms may require some 

 explanation: — 



Sucrose. — This is the crystallizable cane sugar. 



Glucose. — The uncrystallizable sugar, which is all left in the 

 molasses. 



Solids not Sugar or Non-Sugars. — These are the soluble 

 solids, other than sucrose and glucose, contained in the juice. 

 The sum of the sucrose, glucose, and non-sugars in the juice is 

 known as +he total solids. 



Glucose Ratio. — The proportion of glucose in the juice to 

 every hundred parts of sucrose. 



Quotient of Purity. — The proportion of sucrose to every 

 hundred parts of total solids in the juice.
