40 VERTICAL FARMING 



Thorough subsoil blasting opens up these subsoils and permits 

 the drains to collect and carry away the water that has rendered 

 the fields worthless. 



Dynamite and farm powders are also being used to control 

 old-established gullies or washes. The banks are shot down 

 into the bottom of the gully so that teams can be driven across 

 to plow the banks down to the desired level. This shattering 

 also loosens deeply and increases the immediate absorption of 

 water and benefits further by holding out of the surface drain- 

 age much of the water that before increased the run off and 

 attending erosion.
