TWENTY-FIRST CHAPTER. 



TABLE OF ANALYSES AND VALUATIONS. 



ASA sort of ready reference I give the following 

 table, showing composition and valuation of 

 the more important substances purchasable for 

 manurial purposes. The analyses, for the most part, 

 represent an average of a number of samples, and 

 the valuation is compounded on the basis of this 

 year's schedule of prices as adopted by our experi- 

 ment station. Delivered on the farm, these mater- 

 ials have a correspondingly larger value: —
