Praise From Farm Owner 



Permit me to express my gratefulness to 

 you for the I.C.S. chemical analysis of my 

 soil. In keeping with the knowledge that 

 I gained from the studies of the I.C.S. 

 Agricultural Courses, the analysis of my 

 soil has made it more clear to me that my 

 soil is lacking in the plant foods nitrogen, 

 phosphorus, potassium, calcium, magne- 

 sium, and organic matter, and also gave 

 me the quantity of these foods that should 

 be added to the acre for profitable results. 

 In addition to these, it proved that my 

 soil is not acid, and saved me of the ex- 

 penditure for 30 tons of lime, which I 

 thought my soil needed. I left the farm in 

 1900 after working 5 years as a farm hand, 

 but returned again 3 years ago, taking up 

 farming for myself. It was then, seeing 

 my deficiency, I immediately enrolled for 

 the Agricultural Course of the I.C.S. I 

 greatly appreciate the time spent in and 

 the understanding received by studying 

 these Courses. I am sure half of my suc- 

 cess would have been lost had I done 

 other than studying.
