 pliance with the law would entail. 



It has been customary to publish, with the 

 results of analysis, also an estimate of the 

 commercial value per ton of each brand of 

 fertilizer. This estimated commercial value 

 is obtained by multiplying the pounds of 

 each element or combinations of the element 

 in a ton by a value per pound. To the value 

 of the fertilizer thus obtained is added some- 

 thing for cost of mixing, bagging 

 and freight, and something for profit. 

 The price per pound given to each 

 element or combinations of the elements 

 is based upon the commercial value of 

 the element when purchased in raw mate- 

 rials. The price for each year is usually 

 determined by a conference of those in con-

 a matter of fact, the price varies little from 

 year to year.

 tute a table of comparative commercial 

 values as determined by the most expert
