require, with little trouble, by watering the pipes with a 

 watering pot. 



The annexed plans, will explain more fully the arrange- 

 ment of the apparatus ; and I am persuaded that the advan- 

 tages of this mode of heating, with its great simplicity, will 

 give satisfaction to every practical gardener who has an op- 

 portunity of trying it. When once the water is heated, and 

 the fires well made, he may retire to rest, certain that the 

 pipes will not get cold during the night, but retain a con- 

 siderable heat in the morning. 



I have the honour to be, Sir, 

 Your most obedient humble servant,

A, Boiler. 



B, B, Cast-iron pipes that convey the water to the iron 

 reservoirs at the ends of the house. 



C, C, Cast-iron reservoirs. 



D, D, Smoke flues, which are conducted by the sides of 

 the water-pipes, return at each end of the house, go under 

 the paths, and are brought in the back wall to Chimneys at 

 E, E, in the fire-place shed. 



There are dampers in each chimney when they are both 

 open ; the smoke from the fire-place passes through the flues 

 of both east and west compartments of the house, but the 

 heat may be confined to one compartment by closing the flue 

 of the other with the damper.
