 are always much poorer in the plastic or flesh-form- 

 ing elements than the seed ; on this account, we enu- 

 merate the latter with the very invigorating and 

 strongly nutritive, the former with the less invigorat- 

 ing and slightly nutritive kinds of food. The follow-

A mere glance at these figures will probably be 

 sufficient to induce the intelligent farmer to associate 

 with such means of nourishment as are poor in ni- 

 trogen (for example, roots, potatoes, &c.) others rich 

 in this element (for example, bruised corn, coddled 

 grain, or, what indeed is cheapest, oil-cake) ; and 

 more so, as the full benefit derivable from the former 

 is secured only when the proper proportion of the 

 latter is present. This proportion may be considered 

 about the same with that found in good meadow or
