 slightly increasing the floor space, it seems 

 to increase the yield possibilities. In the 

 writer's experience, however, the first and 

 last parts of the crop harvested from ridge 

 beds have a tendency to run lighter in 

 weight as compared with the product from 

 the continuous flat bed. 



Installation, Whatever may be the type
