also supplies a range of four-inch pipe, which goes 

 round the pit. There are cavities in the wall to per- 

 mit the steam from below to pass to the top of the 

 pit. The aperture to those can be closed at pleasure, 

 thus insuring a perfect command over the moisture of 

 the atmosphere. There is a chamber which formerly 

 contained a flue belonging to the house that occupied 

 the place of the one we are now describing. This 

 chamber has been left with the view of its being 

 useful for filling with hot dung, either for the purpose 

 of assisting to maintain the heat of the house^ or 

 for destroying insects. The tanks and pipes cannot 

 both be worked at the same time, but they are fitted 

 with stop-cocks, so that either can be worked at 

 pleasure ; and a few hours in the middle of the day, 

 when the pipes are not wanted, is found amply suffi- 

 cient to keep up the bottom heat, as the mass of 

 material, when once heated, retains its heat for a con- 

 siderable time. (Gard. Chron.)

 morning until night. Where about fifty pine plants
