GROUND PLAN 

 ("Knock Down" Construction) 



Boards are laid on top of sand and gravel fill. Makes bed mole- 

 and gopher-proof. Provides easy shoveling surface for emptying 

 bed, without disturbing sand till. Improves drainage and aera- 

 tion. 



PRACTICAL UTILITY 



This bed is a most practical, all-purpose culture bed. While 

 the depth should be kerjt at two feet, the length and breadth may 

 bFyaned to suit individual needs. We use lugbox culture for 

 rapid production of earthworm egg-capsules. We take the in- 

 crease and impregnate larger culture beds, such as illustrated, for 

 soil-building and for development of vast numbers of earthworms. 

 This construction provides an excellent unit for household garbage 

 disposal and for general composting of all kinds of organic 

 waste manures, grass clippings, leaves, etc.
