A LL progressive farmers and orchardists know that 

 trees planted in blasted ground grow much faster 

 than those planted in the old way and bear fruit earlier. 

 This proves the truth of the principles of Vertical 

 Farming, which aims to cultivate downward as well as 

 to till the top soil. 



Three years ago tree planting in blasted holes was 

 experimental — now millions of trees are set out by the 

 Vertical Farming method every Spring and Fall. 



In like manner, blasting the subsoil to increase 

 general crop yields, now regarded as experimental, 

 will in a few years be common. 



To learn how and why Vertical Farming may double 

 the yields of your farm, get the Free Reading Course 

 in Vertical Farming by Dr. G. E. Bailey, one of the 

 best works on soils and soil culture ever published.
