Food for Thus in the low grade "complete fertilizers" the con- 



8 sumer pays more for his Nitrogen than he pays for it in 



*34 Nitrate of Soda at One Hundred Dollars ($100.00) per 

 ton ! ! ! 



In the medium grade " complete fertilizers" he pays 

 more than he would pay for it in Nitrate of Soda at Eighty 

 Dollars ($80.00) per ton ! ! 



In the high grade "complete fertilizers" he pays as 

 much for it as he would pay for it in Nitrate of Soda at 

 Seventy-One Dollars ($71.00) per ton! 



Besides which, since one must buy nearly Twenty 

 Tons of low grade fertilizer to get a ton of Nitrate of Soda, 

 or anything like its equivalent, there is a material 

 saving in freight which may amount to 95 percent, of the 

 cost. Instead of transporting twenty tons of more or less 

 inert material you need only to pay the freight charges on 

 one ton of concentrated plant food that is: substance 

 instead of shadow. 



Since Nitrate of Soda is the one immediately available 

 Nitrogenous plant food, and costs less per pound for the 

 available Nitrogen it contains, than any other Nitrogenous 

 fertilizer, its rational use is most profitable at present, and 

 has been so since the very beginning of its use in 

 agriculture.
