circumstances cannot otherwise hut differ also more or less seriously. 

 The more phosphoric acid, potash and iu particular nitrogen a given 

 quantity of a fodder article contains, the more valuable, considered 

 from a commercial standpoint, is the obtainable raauurial refuse 

 resulting from its use, taking everytliing else even. The subsequent 

 abstract of our fertilizer analyses of the different fodder articles used 

 on the present occasion may well serve as an illustration of the pre- 

 vious statements.
