THE FEEDING VALUE OF ROOTS 29 



through the difficult time during the war, when the import 

 of f ceding- stuffs ceased, in. a manner which would otherwise 

 have been quite impossible. 



A comparison of the relative importance of the root-crop 

 in Denmark and Great Britain during last century was given in 

 the beginning of this chapter. It will be worth while to see 

 how the root- crops in the two countries compare now, and how 

 they have developed during the war, quoting the official 

 statistics of both countries. In Great Britain the acreage under 

 mangels, swedes, and turnips was in 1912 13'6 per cent, of the 

 total arable land, in 1918 it was considerably less, viz. 10-8 per 

 cent. In Denmark it was in 1912 relatively less than what it 

 was in Great Britain, viz. 10 -2 per cent., but it increased during 

 the war, and was in 1918 11*1 per cent. If we calculate the 

 proportion between the acreage under mangels, swedes, and 

 turnips and the total acreage under crops and grass, the rela- 

 tively great importance of the root-crop in Danish Agriculture 

 is more conspicuous.
