The official report of analyses and of all materials used for manu- 

 rial purposes, which are sold in this state under a certificate of com- 

 pliance with the present laws for the regulation of the trade in these 

 articles, has been restricted to a statement of chemical composition 

 and to such additional information as relates to the former. 



The practice of affixing to each analysis of this class of fertilizers 

 an approximate commercial valuation per ton of their principal con- 

 stituents has, therefore, been discontinued. Those ^ho are not yet 

 familiar with the current market value of fertilizing ingredients may 

 benefit by a short discussion of that subject at the close of tliis Bul- 

 letin.
