the mangold crop is one. In the second place, only one- 

 third of the cost of dung applied to mangolds is credited 

 to them and carried forward to other crops, whilst no part 

 of the cost of artificials applied is carried forward, except 

 in the case of basic slag, or other manure of long duration. 

 In the case of turnips consumed on the land it will be remem-

bered that the whole cost of manures was credited, these 

 being generally consumed on the land, but mangolds are 

 invariably carted off, and except as above the whole cost 

 has been taken as being absorbed into the crop. 



The net cost for the mangold crop (Table XVII) has 

 been analysed on the basis of the cost of one acre. Unfor- 

 tunately, in this case, as also with the turnips, no records of 

 yields by weight were kept and no ton-costs, nor an analysis 

 of them, can be given.
