PIT in the Stove is the excavation, or brick inclosure, 

 in which is the tan, or other material for plunging the 

 pots ; and for Forcing, it is a structure having a glass 

 roof, and differing from a hotbed and frame only in being 

 large, and with sides fixed to the soil. (See HOTBED and 

 MELON for examples of various kinds of Pit.) A Cold 

 Pit is one where no artificial heat is used, the protection 

 the plants receive being given solely by coverings. 

 During summer and spring, these pits, when not covered, 

 are still a great protection to plants by their walls. 

 Either a Melon or Cucumber Pit unheated, or an inclosure 

 made with turf walls, and covered with the glass lights 

 of a hotbed frame, answer admirably as cold pits.
