VERTICAL FARiMING 



PART VI 



Cultivation Use of Explosives 



The present means and methods of cultivation are behind 

 the times. They are not up to date with the progress made all 

 along other lines. They all work too shallow, cultivating the 

 land a few inches where they should loosen and stir to a depth 

 of several feet. A world of wealth in thought, money, inven- 

 tion and machinery has been bestowed upon the first few inches 

 of the soil at the surface, but up-to-date agriculture demands 

 that the depths of the soil be considered also. It is not enough 

 to just scratch the surface and leave untouched the storehouse 

 of wealth below. 



A World of Tools. The farmer has at his command for 

 working this thin skin of the surface inches a wonderful array 

 of tools. He has plows of all kinds and qualities to select from 

 to fit every surface condition imaginable hillside, landside, 

 hinge, and swivel plows equipped with every shape of mold- 

 board, and coulters that may be fin, knife or rocking.' He may 

 use hand, sulky, or motor plows, and work them single, double, 

 or in gangs. He has harrows without number, home-made and 

 latest patent, coulter, spring, chain, slicing, spading and cuta- 

 way, all of them equipped with teeth set vertical or set slanting, 

 with plain, twisted, shovel, coulter, spike, and spring teeth in a 

 bewildering dental display. He has cultivators of all sorts and 

 breeds hand, walking, and riding. He has drags, rollers, 

 plankers, floats, boats, clod crushers, pulverizers, and smooth- 

 ers, and he has so-called subsoilers in good variety that work 

 only a few inches deeper than the tools already mentioned.
