EARTHWORM CULTURE 127 



definite plans for culture boxes, culture beds, and so on. How- 

 ever, each earthworm culturist should experiment and develop 

 plans of his own. Any kind of box, container, or culture bed 

 will serve, provided that it has good drainage and is kept shaded 

 and moist. The plans we have set forth have been found, 

 through long experience, to be good. By following a successful 

 plan that has already been tested, the beginner will avoid many 

 mistakes. On the other hand, if no experimenting is carried out, 

 new and better methods will not be discovered.
