Tlio above selectidii of one beet, of ai)pn)xiniately avcraj^e 

 \vcij:[bt. from each of the four varieties naturally loft the remain- 

 ing five beets in each class divided into two sections, one soctiun 

 ((") consistinj^ of beets UTider the average weight, and the other 

 section ( </ ) of beets over the average. The beets belonging to 

 each section were then minced u]) together, and each section 

 separately analysed as one sample. Thus the following results 

 were ol)tained : —

T (d) ... 2 203/. I 82.72 1.44 12.70 — 



The results in the al)ove two tables bear out the generally 

 accepted view that small beets contain more sugar than large 

 ones of the same class. The best all-round results are those of 

 Classes II and III. which, it will be noted, do not show a high 

 moisture content. 



The average results obtained from the four classes of beet 

 are set forth in the following table : — 



Water Asli Cane Sugar Total Sugar 



Class. per cent. per cent. per cent, p^r cent. 



I 82.37 1.46 14. or 15.89 



II 80.25 1.2^ 16.46 18.05 



III 78.83 1. 31 16.17 17.86 



IV 80.77 1.29 18. TC) 18.43 



In this table of averages,' allowance must of cotirse be made 

 for the fact that in Classes III and IV there were only two deter- 

 minations of cane sugar made, and in each case only in one beet. 

 In Class IV the average perce;itage of cane sugar would certainly 

 have been lowered by determinations in respect of IVV and l\ d. 



A second lot of beets of Class II, sown early in .'^cinember, 

 191 5, was supplied by Mr. Edmeades in March, from the farm 

 *' Gwaayang," 6^2 miles south-west of (leorge. This soil had 

 had a little irrigation, and had been treated with cow manure. 

 All the beets comi)osing this lot were cut up together and analysed 

 as one sample, the resulting i)ercentages of cane and total sugar 

 being res])ectively tS.cji and -^0.59. 



These records may justly include sotne reference to a tew 

 chemical investigations made in the Laboratory at Cedara, Xatal. 

 prior to Union. In 1907 roots of the Klein W'anzelebener and 

 White Viltnorin varieties, grown at Inchanga. were harvested
