292 SYSTEMS OF PERMANENT AGRICULTURE 



maintain permanent systems of profitable agriculture, he cannot 

 accept ' parrot ' instruction," not even when offered by the fer- 

 tilizer agent. 



The fact that acid phosphate and " 2-8-2 " fertilizers are still 

 used in the Eastern and Southern states, largely as soil stimulants 

 and for a single crop, or for one year's effect only, fairly raises the 

 question whether agricultural practice in those states is not influ- 

 enced more by the "arguments" of the fertilizer agent than by the 

 established facts and principles from the experiment stations. 



RAW ROCK PHOSPHATE, "FLOATS" 



PUBLISHED BY 

 THE NATIONAL FERTILIZER ASSOCIATION 



For years the raw rock question has cropped out spasmodically, in different 

 parts of the world, like the measles or some other affliction. 



Sometimes it was the result of the recommendation of some impractical 

 theorist who occupied a position that brought him before the farmer oftener 

 it was foisted on an unsuspecting farming community by some one who was 

 either directly or indirectly interested in an offgrade phosphate mine, and who 

 used his official position to further the interests of the rock mine at the expense 

 of the farmer. 



But no matter what started its use, the result has always been the same no 

 benefit derived from its use a distrust of legitimate fertilizers, and a distinct 

 set-back to agricultural interests which has taken several years to overcome. 



In the following pages we give you the opinions of foreign experiment station 

 men as well as those of our own country. 



Both statistics and your good common sense tell you that the older the state 

 or country, the more fertilizers are used and the greater the knowledge they 

 have of their use. 



The mere fact that in these older communities, both abroad and in this 

 country, the use of legitimate fertilizers has increased rapidly from year to year 

 for a hundred years conclusively shows their value. 



The fact that wherever raw rock has been used, its use has been abandoned, 

 shows its worthlessness. 



Read what authorities who know have to say on this subject. 



RESOLUTION passed by the Association of German Agricultural Experiment 

 Stations, in congress assembled, September 14, 1907, at Dresden, Germany: 



"As a result of the extensive advertising which is done by certain parties ad- 

 vocating the use of RAW ROCK PHOSPHATE, the association passed the follow- 

 ing resolution: 



"THE ASSOCIATION HAS CONCLUDED, FROM FERTILIZER EXPERIMENTS AT 

 HAND WITH RAW PHOSPHATE FERTILIZER, THAT THERE IS SHOWN NO PROFIT-
