T WO HUNDRED MILLION people eat 
foods grown largely by the aid of commer¬ 
cial fertilizer. In the United States alone nearly 
seven million tons of fertilizer are used annually. 
The Fertilizer Industry performs a most 
valuable service in searching the four corners 
of the earth, gathering sulphur from Spain, 
nitrogen from Chili, phosphate from Florida 
and Tennessee, and potash from the West; 
in recovering waste materials from slaughter 
houses, factories and cities; in reaching up into 
the air and down into the bowels of the earth 
for newer and cheaper forms of raw materials; 
and then manufacturing the whole into a pro¬ 
duct, definite in composition and convenient in 
form, which can be transformed into essential 
life-giving foods. 
The machinery, buildings and equipment 
necessary to perform this great service represent an 
investment running high into the millions of dollars. 
Without fertilizer, agriculture would deteriorate. 
With more fertilizer, agriculture will improve. The use of fer¬ 
tilizer is rapidly becoming universal, and the best use for the 
greatest profit should interest every farmer wherever located. 
Have You Investigated the Possibilities? 
Old theories are being discarded. New fields for 
profitable use of fertilizer are rapidly developing. Have you 
thought of fertilizing that weedy, run-down pasture? Do you 
know that fertilizer can help you to avoid soft corn ? escape the 
Hessian Fly ? overcome drouth ? save farm labor ? get higher prices ? 
Study fertilizer. Let fertilizer make bigger profits for you.
