VALUATIONS. 



To have a basis for comparing the values of different fertilizer mate- 

 rials and fertilizers, it is necessary to assign prices to the three valu- 

 able constituents of fertilizers — ammonia, phosphoric acid, and potash. 

 These figures, expressing relative value per ton, are not intended to 

 represent crop-producing power, or agricultural value, but are estimates 

 of the commercial value of ammonia, phosphoric acid and potash in the 

 materials supplying them. These values are only approximate, as the 

 cost of fertilizing materials is liable to change as other commercial 

 products are, but they are believed to fairly represent the cost of making 

 and putting fertilizers on the market. They are based on a careful 

 examination of trade conditions, wholesale and retail, and upon quota- 

 tions of manufacturers. 



Relative value per ton, or the figures showing this, represents the 

 prices on board the cars at the factory, in retail lots of five tons or less, 

 for cash. 



To make a complete fertilizer the factories have to mix together in 

 proper proportions materials containing ammonia, phosphoric acid and 

 potash. This costs something. For this reason it is thought well to have 

 two sets of valuations — one for the raw or unmixed materials, such as 

 acid phosphate, kainit, cotton-seed meal, etc., and one for mixed fer- 

 tilizers.
