Experiments in the Growth of Sugar Beet. 47 



months of July and August the rainfall of the kingdom was 

 considerably less, and the period of bright sunshine was more, 

 than the average/ 5 



The year was one in which the }deld of mangolds in Gf eat 

 Britain as a whoJe was 17.65 tons per acre according to the 

 official produce statistics. This was nearly a third of a ton 

 per acre over the average. The mean yield of sugar-beet on 

 the plots enumerated in the accompanying tables is 24*2 tons 

 with leaf and 16*3 tons without leaf. The growers ot these 

 experimental crops state their estimated yields of mangolds 

 in the same season at figures wnich in only three cases fall 

 below twenty tons, and range from that estimate to over forty, 

 and in a single instance as high as sixty tons, the average 

 mangold production of the experimenters being 26*2 tons 

 per acre. 



In the following tables the counties are arranged in the 

 geographical divisions adopted in the Agricultural Returns. 

 Table I. shows the area sown with sugar beetroot, together 

 with the yield and other particulars relating to the cultiva- 

 tion and treatment of the crop. Table II. shows the results of 

 the examinations of the beets supplied to the analysts by 

 the growers. The reference numbers in Table II. apply to 

 the experimenters and crops bearing the same numbers in 

 Table I. 



From Table II. it will be seen that the average quantity of 

 sugar in 100 parts of the juice, as reported by the analysts who 

 examined the samples, works out to 15*65 ; that the average 

 quotient of purity was 85*19 ; and that the average quantity 

 of sugar in 100 parts of the roots was 14*48.
