The figures in this table show how many pounds of 

 Nitrogen are withdrawn from two and one-half acres of 

 ground.

 consumer pays more for his Nitrogen than he pays for 

 it in Nitrate of Soda at One Hundred Dollars ($100.00) 

 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!

 or less inert material you need only to pay the freight
