 of 21 trials in Suffolk in 1906 gave an average yield of 

 14 tons 17 cwt-. per acre, with a sugar content of 16*2 1 per 

 cent. In these trials four cases showed yields of 14 tons, 18 

 tons, 18 tons 15 cwt., and 20 tons 2 cwt., with sugar content 

 of 19*4 per cent., 19*65 per cent., 17*23 per cent., and 16*16

Cost per Acre. — In so far as the 



cost 



of growi 



ng and 



harvesting an acre of sugar-beets is concerned, a good deal 



depends on the soil and local conditions, and there are con- 

 siderable differences between farms in the same district. 

 According to data given by the agricultural school (cornice) 

 at Laon, the net cost of an acre may be estimated as : —
