This little furnace, which is constructed principally 

 of sheet iron, is made double, that part of it which 

 contains the burning charcoal being cylindrical, or 

 nearly so, and being suspended in the axis of a hollow 

 cone, which forms the body of the furnace, and serves 

 as a covering for confining the heat. 



The following figure, which represents a vertical sec- 

 tion of this furnace through its axis, will give a clear 

 idea of the manner in which it is constructed : 



Fig. 57. 



The air is introduced into the fire-place first through 

 a circular hole (represented in the Fig. 56), about i 

 inches in diameter, situated in the side of the hollow 

 cone near its bottom ; and from thence it passes up 

 through a small dishing-grate of cast iron which lies at 

 the bottom of the hollow cylinder which contains the 

 burning fuel. At the upper end of this cylinder there 

 is a narrow rim about half an inch wide, turned out- 

 wards, by which the cylinder is suspended in its place ; 

 and a similar rim being turned inwards below serves as 

 a support for the dishing-grate. 



When this fire-place is used, it will be proper to 

 place it on a flat stone or on a tile ; or, what will be 

 still better, to set it in a thin earthen dish. 



The same earthen dishes which would be proper for
