them must finally turn upon tlie amount of nutriment produced 

 from a given area of land and the cost of production. Woll * 

 presents the following table, showing the green substance and the 

 dry matter yielded by both crops at four Stations: 



Yield and dry matter per acre of roots and green fodder com — Four 

 Stations. 



It is seen that fodder corn yields about twice the dry matter 

 that can be secured from a crop of roots grown on the same land. 



394. Dry matter in silage and roots. — The value of the dry 

 matter of roots and silage for milk production has been studied 

 at the Ohio, « Pennsylvania ^ and Vermont ^ Stations with the fol- 

 lowing results: 



Milk produced by feeding one hundred pounds of dry matter in com 

 silage and beet rations — Three Stations. 



It will be seen that although practically all of the dry matter 

 of beets is digestible, while a considerable portion of that in com 

 silage is not, dairy cows, when fed rations consisting largely of
