of less capacity, and made the flue to go round the sides of the boiler ; it is then 
of great length and very effective ; and this I consider the best and most simple 
plan for an open-topped boiler, serving as a partial reservoir of heat. 
A boiler in the form of half a hollow cylinder, affording a great quantity of fire 
and flue surface, is made by Messrs. Bailey (fig. 3), and a bottle-shaped boiler 
is made by Messrs. Cottam and Hallam (fig. 4), which has a considerable quantity 
of fire and flue surface, compared with its capacity ; both these are, therefore, well 
adapted to cases where only a small reserve of heat is required for night. The 
variation of the Scotch distillers' boiler (5) is also a good form for maintaining 
the supply of heat to the house, while a separate reservoir is warmed by one of 
the pipes. 
Another mode of obtaining a large portion of fire and flue surface to a small 
capacity, is shown in figure 7 out complicated forms have little to recommend 
them, and are expensive, except when so small as to be cast in iron, because the 
fire should be partially surrounded by slow conductors of heat, to prevent the 
dissipation of heat being too rapid, and to render the combustion of the fuel 
perfect, and, consequently more effectual ; hence, a fire-place surrounded on three 
sides by bricks is better than one in the middle of the boiler. 
The best mode of regulating the fire is by means of a door to the ash-pit, 
having a register, first suggested by Dr. Black, and afterwards put in practice by 
Count Rumford.

The house now appropriated to the culture of stove plants at Chatsworth, was 
originally built for a greenhouse, to which purpose it was devoted, until little more 
than three years ago, when the interior was remodelled, and a new glass roof was 
placed on it, making of it an excellent plant stove.
