TARIFF OF PRICES OF FERTILIZER-

226); is given below, with the prices estimated in gold^Qv 

 pound. 



The editor greatly regrets that he has not had the time 

 or the opportunity to make a careful examination of the 

 various forms in which nitrogen, phosphoric acid, and pot- 

 ash, are to be had in this country, so that this tariff miglit 

 be conformed therewith, and answer the same purpose for 

 the American farmer that the original one does for the 

 farmers throughout Germany. But, nevertheless, the 

 values allowed for these three substances in the tariff as 

 it stands are not far out of the way. Prof Johnson {Be- 

 port to the Secretary of the State Board of Agriculture, 

 0)1 Commercial Manures, April, 1869) gives the follo\ving 

 values in gold: potash, 4 cents; soluble phosplioric acid, 

 12|- cents; insoluble, 4^ cents; nitrogen, 17 cents. The 

 mean of the four values of nitrogen in Stockhardt's tariff 

 is 17.9 cents. 



Prof. Johnson says very truly in the same report, " The 

 farmer will not often err in refusing to lay out his money 

 for any article whose cost much exceeds the calculated 

 Aalue," with reference to his own tariff; and the same- may 

 as well be said of the scale of prices adopted in this work.
