 spaces leave room to draw out the trays from the 

 racks when the worms are being attended to.

 either side of the racks between them and the 

 wall. In this space two single racks may be 

 placed on either side of the room, leaving the 

 opposite diagonal corners for two tables, which 

 will be found necessary for various kinds of
