THE GREEN-HOUSE AND CONSERVATORY. 



The heating apparatus may vary at the caprice of the 

 owner ; as these pits waste but little heat, a common brick 

 stove will answer every purpose, and consumes but 

 little fuel. 



This mode of heating is used by Mr. Rivers in all his 

 pits and green-houses, and is thus described : 



The stove is a small mass of brick work, about two 

 feet square and three feet high ; or it may be larger, if 

 great heat is required, the front looking thus : 



On opening the cast iron door, you see a 

 small chamber about twelve inches square, 

 with a grate at the bottom, on which the fire 

 is made ; the other door, ?>, opens to an ash 

 pit, of the same size, or perhaps deeper, 

 below the fire.
