 and sheep, but should be used in connection with dry food and 

 salt. Hogs likewise prosper upon them ; and when the ground 

 is not frozen, they can help themselves and save the cost of har 

 vesting. The nourishing quality of the root is very little, if any 

 lower than that of the potato, while its inorganic constituents 

 are more useful. The stalks are nearly as valuable as the tu 

 bers; and in this respect it has an advantage over the potato. 

 Although cutting the stalk in the beginning of September may 

 diminish the growth of the tubers which is questionable the 

 fodder that is obtained at that season will fully compensate for 

 the loss. 



According to Schwertz, 100 kilogrammes (220.548 Ibs. av 

 oirdupois) of green stalks, equal as regards nutritious qualities 

 31.250 kilogrammes of hay; but the value is increased if they 

 are mixed with other vegetable matters. If for winter fodder, 

 the stalks should be left as late as possible, cut, and dried as hay ; 

 and in this condition all domeetic animals eat them. In some 

 parts of Europe, the stalks are also used as fuel; and Boussin- 

 gault found them profitable as absorbers of liquid manure, ow
